Forward Looking Statements

This Annual Report on Form 10-K contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “forecast,” “project,” “should” or “will” or other comparable words or the negative of such words. The accuracy of the Company’s assumptions, expectations, beliefs and projections depend on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. Our actual future results might differ from the forward-looking statements made in this Annual Report on Form 10-K for a variety of reasons, which include: our inability to successfully and timely complete our various vessel construction and conversion programs, especially our MPSV program, which involves the construction and integration of highly complex vessels and systems; unsuccessful operations of our MPSVs, which are a class of vessels that we have not previously owned or operated; the inability to successfully market our MPSVs at dayrates that we have forecasted; unplanned customer suspensions; cancellations or non-renewals of vessel charters; loss of customers; uncollectible accounts receivable; the financial stability of our customers; industry risks; activity levels in the energy markets; changes in capital spending budgets by customers; effects of competition; fluctuations in oil and natural gas prices; variations in demand for vessel services; changes in demand for refined production products or methods of delivery; increases in operating costs; the inability to accurately predict vessel utilization levels and dayrates; changes in laws that affect our domestic or international operations; less than anticipated subsea infrastructure demand activity in the GoM and other markets; the level of fleet additions by competitors that could result in over-capacity; economic and political risks; weather related risks; the ability to attract and retain qualified marine personnel; regulatory risks; the repeal or administrative weakening of the Jones Act; our ability to successfully integrate acquisitions; our ability to maintain adequate levels of insurance; drydocking delays and cost overruns and related risks; vessel accidents; oil spills; acts of terrorism; unexpected litigation and insurance expenses; our ability to finance operations or access debt and equity markets; fluctuations in foreign currency valuations compared to the U.S. dollar; risks associated with foreign operations and the expansion thereof; adverse domestic or foreign tax consequences and other risks described under the heading “Risk Factors” of this Annual Report on Form 10-K. Should one or more of the foregoing risks or uncertainties materialize, or should our underlying assumptions prove incorrect, our actual results may vary materially from those anticipated in our forward-looking statements, and our business, financial condition and results of operations could be materially and adversely affected.

BUSINESS

General

We are a leading provider of technologically advanced, new generation OSVs serving the offshore oil and gas industry, primarily in the U.S. Gulf of Mexico, or GoM, and in select international markets. The primary focus of our OSV business is on complex exploration and production activities, which include deepwater, ultra-deepwater, deep well and other logistically demanding projects. Such other projects include, among others, the construction, installation, inspection, repair and maintenance of offshore infrastructure and military and specialty services. We also provide to other vessel owners, vessel management services including crewing, daily operations management and maintenance activities. Through our ocean-going tug and tank barge, or TTB, segment, we are a leading transporter of petroleum products serving the energy industry, primarily in the northeastern United States, the GoM and Puerto Rico. Although our vessels can operate in domestic and international waters, both of our fleets are predominately comprised of vessels that are qualified under Section 27 of the Merchant Marine Act of 1920, also known as the Jones Act, to engage in the U.S. coastwise trade. Foreign owned, built or crewed vessels are restricted in their ability to conduct U.S. coastwise trade and are typically excluded from such trade.

In the mid-1990s, oil and gas producers began seeking large hydrocarbon reserves at deeper well depths using new, specialized drilling and production equipment. We recognized that the then-existing fleet of conventional OSVs operating in the GoM was not designed to support these more complex projects or to operate in the challenging environments in which they were conducted. Therefore, in 1997, we began a program to construct new generation OSVs based upon our proprietary designs. Since that time, through a series of newbuild programs, we have constructed 17 new generation OSVs and currently have 16 new

Index to Financial Statements

generation OSVs and four MPSVs under construction or conversion. All 17 of the new generation OSVs that we have constructed to date, and all but one of the 16 such vessels that we currently have under construction, have been built using proprietary designs. We have further expanded our OSV fleet through multiple vessel acquisitions. These acquisitions, in the aggregate, were comprised of 16 new generation OSVs, 10 conventional OSVs and two AHTS vessels. Our new generation OSV fleet is among the youngest in the industry with an average age of approximately eight years.

Our OSV fleet was purposefully assembled with the flexibility to meet the diverse needs of our clients in all stages of their exploration and production activities. All of the new generation vessels in our OSV fleet have enhanced capabilities that allow them to more effectively support premium drilling equipment required for deep drilling and related specialty services. Such vessels have dynamic positioning capability, as well as greater storage and off-loading capacity. The new generation vessels in our OSV fleet are capable of providing services to our customers anywhere in the world. While we are committed to maintaining a critical mass of new generation vessels operating in the GoM, we currently have vessels working offshore Mexico, Trinidad and Qatar and are actively pursuing additional contracts in these and select other U.S and international markets.

Our TTB operating fleet currently consists of 16 ocean-going tugs and 21 ocean-going tank barges. Since 2005, we have taken delivery of eight new double-hulled tank barges and seven retrofitted tugs under our first and second TTB newbuild programs, with one additional tug expected to be delivered during the second quarter of 2008. These newbuild tank barges added 780,000 barrels of double-hulled capacity, more than replacing the 180,000 barrels of carrying capacity permanently lost when we retired two of our single-hulled tank barges from service at the end of 2004 as mandated by OPA 90. With the delivery of all of the double-hulled tank barges under our first and second TTB newbuild programs, 50% of our tank barge fleet barrel-carrying capacity is now double-hulled, up from 7% at the end of 2004.

We believe that our TTB business complements our OSV business by providing additional revenue and geographic diversification, while allowing us to offer another service line to integrated oil and gas companies. For example, we have been successful in deploying our TTB equipment to non-traditional markets, such as supporting deepwater well testing and other specialty applications for our upstream customers in the GoM. In addition, our TTB equipment has occasionally transited to the Great Lakes and GoM regions to perform traditional petroleum transportation services. However, demand for our TTB services has historically been driven by the level of refined petroleum product consumption in the northeastern United States and Puerto Rico, our core operating markets. Demand for refined petroleum products is primarily driven by population growth, the strength of the U.S. economy, seasonal weather patterns, oil prices and competition from alternate energy sources.

Offshore Supply Vessels

The OSV Industry

OSVs primarily serve exploratory and developmental drilling rigs and production facilities. They also support offshore construction and subsea maintenance activities. OSVs differ from other types of marine vessels in terms of their cargo carrying flexibility and capacity. In

Index to Financial Statements

addition to transporting deck cargo, such as pipe or drummed material and equipment, OSVs also transport liquid mud, potable and drilling water, diesel fuel, dry bulk cement and personnel between shore bases and offshore rigs and facilities. In general, demand for OSVs, as evidenced by dayrates and utilization rates, is primarily related to offshore oil and natural gas exploration, development and production activity, which in turn is influenced by a number of factors, including the drilling budgets of offshore exploration and production companies and oil and natural gas prices. Increasingly, demand for our OSVs has come from specialty services to the energy industry and military applications.

OSVs operate worldwide, but are generally concentrated in relatively few offshore regions with high levels of exploration and development activity such as the GoM, the North Sea, Southeast Asia, West Africa, Latin America and the Middle East. While there is some vessel migration between regions, key factors such as mobilization costs, vessel suitability and government statutes prohibiting foreign-flagged vessels from operating in certain waters, or cabotage laws such as the Jones Act, can limit the migration of OSVs.

MPSVs also support the offshore exploration and production activities of the energy industry. MPSVs are distinguished from OSVs in that they are not solely utilized to provide transportation services, but are significantly larger and more specialized vessels that are principally used to support complex deepwater subsea construction, installation, repair, maintenance and other sophisticated activities. These vessels are usually equipped with a variety of lifting and deployment systems, including large capacity cranes, winches or reel systems that can support a broad array of complex tasks. For example, MPSVs serve as an installation platform for subsea risers, jumpers and umbilicals. MPSVs often support ROV operations, diving activities, well intervention, platform decommissioning and other offshore topside and subsea construction applications. Generally, MPSVs command higher dayrates than OSVs due to their versatility and higher construction and operating costs. Because MPSVs do not typically carry material cargoes, they are not as constrained by cabatoge laws.

The GoM is a critical oil and natural gas supply basin for the United States. Since the late 1990’s, the primary emphasis for the exploratory efforts of offshore operators has increasingly been in the deepwater and ultra-deepwater areas of the GoM rather than the shallow waters of the Continental Shelf. According to the Minerals Management Service, or MMS, from the first major deepwater leasing boom in 1995 to March 2007, oil production grew 525% to 950 thousand barrels per day and natural gas production grew 663% to 3.8 billion cubic feet per day. Recent discoveries of large hydrocarbon reserves in deepwater fields in the GoM and at deeper well depths on the Continental Shelf have resulted in increased developmental and exploratory drilling activities in these areas. The deepwater region of the GoM is an increasingly important source of oil and natural gas production with many unexplored areas of potential oil and natural gas reserves. According to the MMS report, “Deepwater Gulf of Mexico 2006: Americas Expanding Frontier,” there have been over 980 exploration wells drilled in the deepwater GoM since 1995 with at least 126 announced deepwater discoveries over the same time period. Twenty-four deepwater field discoveries have been announced over the last ten years in water depths greater than 7,000 feet. In addition, the pending expiration of leases with substantial reserve potential is expected to stimulate further exploration and development in the GoM. According to the MMS, in 2006 the deepwater region accounted for 73% of total GoM oil production and 38% of total GoM natural gas production, up substantially from 4% and 1%, respectively, in 1990. To capitalize on these

Index to Financial Statements

market trends, rig companies continue to expand their newbuild construction programs to build more deepwater rigs and enhanced ultra-deepwater drillships designed to operate in deepwater and ultra-deepwater regions.

While the shallow waters of the Continental Shelf have been actively explored for decades, until recently, relatively few deep wells have been drilled due to the historically high cost associated with such wells. The higher costs associated with the drilling of deep wells can be attributed to, among other things, the need for specialized, high-end drilling rigs and related equipment, greater volumes of downhole materials such as liquid mud, tubular products and cement, and longer drilling times. Despite the higher costs associated with deep well Continental Shelf drilling, operators, especially those in search of natural gas, have continued to demonstrate interest driven by several factors. The abundance of existing platforms, production facilities and pipelines on the Continental Shelf allow newly discovered deep gas to flow quickly to market. Because oil and natural gas exploration, development and production costs in the shallow well Continental Shelf market are generally lower than those in the deepwater or deep well environments, shallow well drilling activity on the Continental Shelf is typically more sensitive to demand drivers such as commodity prices or the number of jack-up rigs servicing the Continental Shelf. In contrast, the relatively larger capital commitments and longer lead times and investment horizons associated with deepwater, particularly ultra-deepwater, and deep well developments make it less likely that an operator will abandon such projects in response to a temporary decline in commodity prices or the movement of new generation drilling equipment to and from deepwater or deep well environments. We believe that dayrates and utilization rates for new generation vessels that serve the deepwater and deep well markets generally experience less volatility compared to conventional OSVs.

The new generation vessels in our OSV fleet are capable of providing specialty services in support of certain of our customers, including well stimulation, remotely operated vehicles, or ROVs, used in oilfield subsea construction and maintenance, underwater inspections, marine seismic operations, and certain non-energy applications such as fiber optics cable installation, military work and containerized cargo transportation. The deadweight capacity, deck space, berthing accommodations, improved maneuverability and greater fuel efficiency are characteristics of our new generation OSVs that strengthen demand for our vessels in specialty situations.

We have increasingly observed that the technology for exploratory drilling and subsea infrastructure in the deepwater and ultra-deepwater GoM, which has been developed since the late-1990’s, has begun to create repeatable operational efficiencies that have resulted in more predictable outcomes. Oil and gas operators are now capable of deploying proven technologies based on their industry experiences over the past several years. We believe that such operators are more confident in their processes and procedures for drilling wells in deeper waters and that their successes should result in more deepwater field development, deepwater production systems and deepwater infrastructure. Orders for subsea trees continue to grow and it is estimated by industry sources that over $51.0 billion will be invested in subsea equipment from 2007 through 2012, which includes an estimated 2,700 to 3,500 tree installations worldwide. The growth in subsea tree awards is driven by the demand for smaller subsea tiebacks off existing production platforms, as well as robust deepwater drilling activity, particularly in the GoM. As further evidence of this trend, we estimate that there are approximately 50 incremental subsea tiebacks planned or underway in the GoM through 2010.

The Market for New Generation OSVs

Complex exploration, production and construction projects require specialized equipment and higher supply volumes to meet the more difficult operating environments associated with such offshore developments. In order to better serve these projects and meet customer demands, new generation vessels are designed with larger capacities, including greater liquid mud and dry bulk cement capacities, as well as larger areas of open deck space. These features are essential to the effective servicing of deepwater drilling projects, which are often distant from shore-based support infrastructure, because they allow a vessel to make fewer trips to supply the liquid mud, drilling water, dry bulk cement and other needs of the customer. New generation vessels operating in deepwater environments generally require dynamic positioning, or anchorless station-keeping capability, primarily because customers’ safety procedures preclude such vessels from tying up to deepwater installations. In addition, select specialty service customers require these capabilities to conduct offshore operations such as flexible umbilical and flexible pipe laying, saturation diving systems and military support. Dynamic positioning also increases new generation vessels’ ability to safely continue operations in adverse weather conditions. We believe that conventional OSVs, substantially all of which lack dynamic positioning capability and sufficient on-deck or below-deck cargo capacity, are not capable of operating effectively or economically in the deepwater market. In addition, certain ports have draft or other logistical impediments, which limit the pool of new generation vessels capable of servicing such ports. Our proprietary vessels were designed to work under these shallow draft and logistically demanding conditions.

The capabilities and capacities of larger new generation OSVs have resulted in average utilization rates for such OSVs working in the GoM of approximately 95% since their introduction in 1999, a period that spans two significant market downturns. In contrast, the average utilization rate for the conventional OSV fleet over the same period has been approximately 65%, not taking into account cold-stacked conventional OSVs. Additional utilization for new generation OSVs has come from increasing demand for these vessels in support of conventional shelf drilling projects. Moreover, during the same period, average dayrates for new generation OSVs were generally more than double the average dayrates of conventional OSVs. We believe that demand will continue to outpace the supply of new generation OSVs in the GoM for the foreseeable future, despite occasional imbalances of limited duration. We base our belief on the recent and expected drilling and production activity in all sectors of the GoM and the observed departure of certain new generation OSVs to domestic non-oilfield and foreign oilfield markets, after taking into account vessels currently available and vessels being constructed under announced construction plans. Although U.S.-flagged vessels operating in overseas locations may be remobilized to the GoM, remobilization of such vessels has historically been limited.

As of December 31, 2007, our updated internal estimates based on various industry sources indicate that 183 U.S.-flagged new generation OSVs are currently in service, of which we believe 141 are working in the GoM with the remaining 42 working in foreign or non-oilfield markets. Not included in these estimates are 45 announced OSVs that are currently planned or under construction at domestic shipyards, with deliveries ranging from 2008 through 2010. Once all currently announced newbuilds have been delivered by the end of 2010, and assuming that none of them transit to foreign or non-oilfield markets, we project that the visible supply of 187 new generation vessels in the GoM will still be below our current estimate of visible demand for new generation OSVs in the GoM over the same timeframe.

Our OSV Business

We own and operate a fleet of 35 new generation OSVs and 10 conventional OSVs. We also have 16 additional new generation OSVs now under construction. Our new generation fleet also includes two coastwise sulfur tankers that are currently undergoing conversion into MPSVs and two newbuild MPSVs currently under construction. Our logistics shore-base in Port Fourchon, which we recently doubled in size, supports logistics requirements of our new generation fleet, as well as certain of our customers. We also provide vessel management and brokerage services to other vessel owners including crewing and daily management of operations and maintenance activities.

OSVs

In a series of three newbuild programs, we have engineered and supervised the construction of 17 of our OSVs expressly to meet the demands of deepwater regions and other complex drilling projects, based on our proprietary designs. Drawing from the vessel operating experience of our in-house engineers, we work closely with potential charterers to design aspects of our vessels specifically to meet their anticipated needs. This is particularly significant when the charterer will operate a project that could have a duration of more than 20 years and require expenditures exceeding $1 billion. Our 17 proprietary OSVs have up to three times the dry bulk capacity and deck space, two to ten times the liquid mud capacity and two to four times the deck tonnage compared to conventional OSVs. The advanced cargo handling systems of our proprietary OSVs allow for dry bulk and liquid cargos to be loaded and unloaded three times faster than conventional OSVs, while the solid state controls of their engines typically result in 20% greater fuel efficiency than vessels powered by conventional engines. In addition, our proprietary 240 ED, 250 EDF and 265 class vessels were designed, in part, to supply the substantially greater liquid mud volume and other cargo capacity required for ultra-deepwater drilling.

In September 2005, we announced, and have since expanded our fourth OSV newbuild program. This program is now expected to add, in the aggregate, approximately 48,000 deadweight tons of DP-2 capacity to our OSV fleet. We are currently committed under vessel construction contracts with three domestic shipyards to build six 240 ED class OSVs, nine 250 EDF class OSVs and one 285 class new generation OSV, respectively. Projected delivery dates for these 16 vessels range from 2008 through 2010. Our newest proprietary design, the 250 EDF class, is based on our highly successful 240 ED design modified to lengthen the vessel and expand the propulsion package to achieve faster transit speeds. We believe that our customers’ recognition of the superior capabilities of our proprietary OSVs has contributed to our ability to achieve higher dayrates and utilization rates and increased overall operating cost efficiencies compared to our competitors, whether operators of conventional OSVs or new generation vessels.

All of our proprietary new generation OSVs are equipped with dynamic positioning systems and controllable pitch thrusters, which allow our vessels to maintain position with minimal variance, and state-of-the-art safety, emergency power, fire alarm and fire suppression systems and systems monitoring equipment. The unique hull design and integrated rudder and thruster system of our proprietary OSVs provide for a more maneuverable vessel. These proprietary vessels also have double-bottomed and double-sided hulls that should minimize environmental impact in the event of vessel collisions or

Index to Financial Statements

groundings, solid state controls that minimize visible soot and polluting gases and zero discharge sewage and waste systems that minimize the impact on marine environments. In addition, our proprietary OSVs are either fully SOLAS (Safety of Life at Sea) certified or SOLAS ready. SOLAS is the international convention that regulates the technical characteristics of vessels for purposes of ensuring international standards of safety for vessels engaged in commerce between international ports. These features allow us to market our proprietary OSVs for service in international markets.

We have further expanded our OSV fleet through acquisitions. We acquired six 220 class DP-1 new generation OSVs from the Candy Fleet in 2003 and two foreign-flagged AHTS vessels from a private owner in 2005. In August 2007, we completed the acquisition of 20 OSVs, comprised of ten 200 class DP-1 new generation OSVs and ten conventional OSVs and their related business, or the Sea Mar Fleet, from certain affiliates of Nabors Industries, Ltd., or Nabors. We also acquired from Nabors one 285 class DP-2 new generation OSV currently under construction at a domestic shipyard with an anticipated late-2008 delivery. This newbuild vessel is included in our fourth OSV newbuild program discussed above. In connection with the Sea Mar Fleet acquisition, we also agreed to manage nine vessels on behalf of other vessel owners. Under a management agreement, we operate five vessels owned by an affiliate of Nabors in Mexican waters. In a separate operating agreement, we manage four vessels in the GoM on behalf of another vessel owner. We earn operating fees for the management and operation of these vessels. These strategic acquisitions complement our proprietary new generation OSV fleet and have allowed us to expand our service offerings to clients through our growing market presence in domestic and international waters.

MPSVs

In May 2005, we launched an innovative MPSV program, in which we have undertaken the conversion of two former U.S.-flagged sulfur carriers into proprietary 370 class DP-2 MPSVs. Unlike most MPSVs, our 370 class will have significant cargo-carrying capability and will be the first vessels to receive certification by the United States Coast Guard for service under all three of subchapters “L,” “I” and “D” of Title 46 of the Code of Federal Regulations. This unique distinction will allow them to engage in offshore supply, industrial and construction operations, and petroleum transportation services. These MPSVs will have nearly three times the deadweight and liquid mud capacity of one of our 265 class new generation OSVs and more than eight times the liquid mud capacity of one of our 200 class new generation OSVs. The hulls of these two sister vessels, which were purpose-built for the specific gravity of molten sulfur as a cargo, made them uniquely suited to be converted into large liquid mud carriers. This is especially important given the ever-increasing volumes of liquid mud necessary to spud an ultra-deep well today, with some projects requiring as many as 100,000 barrels of drilling fluid per spud. With these MPSVs, we will introduce vessels that can uniquely and single-handedly perform a variety of specialty services for which customers must currently use several vessels or a semi-submersible drilling rig. In addition, these versatile MPSVs will be able to assist in large-volume well-testing, pipeline remediation or flow-back operations. Finally, the vessels can be equipped with a variety of “tool kits” including large capacity cranes, winches and other apparatus to support offshore construction, subsea well intervention, ROV operations, pipe-hauling and flotel services, among others.

In May 2007, we expanded our MPSV program to include the HOS Iron Horse, which is a newbuild MPSV currently under construction at a shipyard in the Netherlands. We further

Index to Financial Statements

expanded the MPSV program in January 2008 with the acquisition of the Superior Achiever, which is being constructed at an affiliate of the same shipyard in the Netherlands. The HOS Iron Horse and Superior Achiever are T-22 class DP-3 new generation MPSVs that will have 8,000 deadweight tons of capacity. They will also each be equipped with two cranes, a helideck, a moon pool and accommodations for 100 or more people. These T-22 MPSVs are designed to handle a variety of global deepwater and ultra-deepwater oilfield applications, many of which are not tied directly to the exploratory rig count. Unlike our 370 class MPSVs, these vessels are not currently configured to have any significant cargo-carrying capacity.

We have agreed to a five-year time charter with Superior Offshore International, Inc., or Superior, for the Superior Achiever or another acceptable vessel at a dayrate of $100,000. Superior will have the option to terminate the charter with 90-days’ advance notice at the end of each sequential six-month period within the five-year term. We currently plan to deploy the HOS Iron Horse in our primary operating market, the deepwater and ultra-deepwater GoM. While the HOS Iron Horse and Superior Achiever are foreign-built vessels and cannot qualify for coastwise trade under the Jones Act, we still intend to U.S.-flag the HOS Iron Horse, which offers certain strategic benefits to us and our GoM customers. The vessels under our MPSV program are expected to be delivered on various dates throughout 2008 and 2009. We also have an exclusive four-year option to construct two additional “sister vessels” based on the same T-22 class DP-3 MPSV design at a U.S. shipyard of our choice, which would qualify for domestic coastwise trade under the Jones Act.

HOS Port

In December 2005, we acquired the lease rights for a shore-base facility in Port Fourchon, Louisiana formerly known as ASCO Magnolia, which we renamed “HOS Port.” The facility lease has seven years remaining on its initial term, with four additional five-year renewal periods. In January 2008, we expanded HOS Port by purchasing a leasehold interest in an additional parcel of improved real estate adjacent to the original site. The new facility lease has approximately six years remaining on its initial term, with four additional five-year renewal periods. The combined acreage of the two adjoining properties now comprising HOS Port is approximately 60 acres, more than double the previous size of HOS Port, which we believe now represents the second largest marine shore-base in Port Fourchon. The newly acquired facility, formerly known as the Rowan Base, increased our shore-base lifting capacity by two cranes, and extended our waterfront bulkhead by over 1,000 additional linear feet to nearly 3,000 total linear feet.

HOS Port not only supports our existing OSV fleet and customers’ logistics requirements, but it underscores our long-term commitment to, and continued favorable outlook for, the GoM as our primary operating market. The acquisition of the Rowan Base will support our rapidly expanding operations in the GoM’s largest deepwater offshore port and provide an expanded lay-down area for our MPSV program.

Tugs and Tank Barges

The Tug and Tank Barge Industry

Introduction. The domestic tank barge industry provides marine transportation of crude oil, petroleum products and petrochemicals by ocean-going tugs and tank barges and is a critical link in the U.S. petroleum distribution chain. Petroleum products are transported in the northeastern United States through a vast network of terminals, tankers and pipelines. According to the Energy Information Administration, or EIA, approximately 240 million barrels of petroleum products were transported in 2006 by tankers and tank barges along the East Coast. Additionally, the EIA estimates that Puerto Rico, another core area of our TTB operation, consumes 234 thousand barrels of oil daily or approximately 85 million barrels annually. Since Puerto Rico relies on imports to meet its energy needs, petroleum products are delivered by tank barge for transportation and electric power generation. According to the EIA, demand for petroleum products in the northeastern United States is expected to increase approximately 1.1% annually through 2011, which we believe will generate steadily increasing demand for the tank barge industry.

The largest tank barge market in the northeastern United States is New York Harbor. Imported petroleum products are primarily delivered to New York Harbor as it has the capacity to receive products in cargo lots of 50,000 tons or more per tanker. By contrast, draft limitations in most New England ports and drawbridge limitations in Boston and Portland, Maine limit the average cargo carrying capacity of direct imports into many of the largest New England ports to about 30,000 tons per tanker. As a result, ships importing directly into New England must frequently discharge in multiple ports or terminals or transfer cargos to tank barges. As existing single-hulled tankers are retired due to age or as mandated under OPA 90, they are typically replaced by larger tankers. These larger-sized tankers are being built to facilitate the importation of crude oil and petroleum products into the United States. According to the EIA, over the last 20 years, importation of crude oil to the Northeast has grown at a compounded annual rate of 1.7% while the volume of imported crude oil and petroleum products is expected to grow at a compound annual rate of 1.5% through 2025.

As larger petroleum tankers are being built, we believe that direct delivery into New York Harbor will generate increased tank barge demand for lightering services and further shipment to New England, the Hudson River and Long Island.

Our Tug and Tank Barge Business

We offer marine transportation, distribution and logistics services primarily in the northeastern United States, the GoM and Puerto Rico with our operating fleet of 16 ocean-going tugs and 21 ocean-going tank barges. We provide our services to major oil companies, refineries and oil traders. Generally, a tug and tank barge work together as a tow to transport refined or bunker grade petroleum products. Our tank barges carry petroleum products that are typically characterized as either clean or dirty. Clean products are primarily gasoline, home heating oil, diesel fuel and jet fuel. Dirty products are mainly crude oils, residual crudes and feedstocks, heavy fuel oils and asphalts.

Our tugs and tank barges serve the northeastern U.S. coast, primarily New York Harbor, by transporting both clean and dirty petroleum products to and from refineries and distribution terminals. Our tugs and tank barges also transport both clean and dirty petroleum products

Index to Financial Statements

from refineries and distribution terminals in Puerto Rico to the Puerto Rico Electric Power Authority and to utilities located on other Caribbean islands. In addition, we provide ship lightering, bunkering and docking services in these markets and are well positioned to provide such services to the increasing number of new tankers that are too large to make direct deliveries to distribution terminals and refineries. Since 2005, we have accessed a new market for our double-hulled tank barges by performing upstream services for our OSV customers in the deepwater GoM. Re-deploying some of our TTB equipment to the GoM provided additional market opportunities with new downstream customers. We now have 45% of our TTB equipment working in the GoM region performing petroleum transportation services. In recent years, our tug and tank barge fleet has also served the Great Lakes region on a seasonal basis to support increased demand for clean fuels during the summer driving season.

During 2005, we completed the construction of two 135,000-barrel barges and three 110,000-barrel barges using proprietary designs, and the retrofit of two 6,100 horsepower tugs. Under our first TTB newbuild program, the Energy 13501 and Energy 13502, Energy 11103, Energy 11104 and Energy 11105, added new cargo-carrying capacity of 600,000 barrels in the aggregate. These five double-hulled barges more than replaced the 270,000 barrels of aggregate barrel-carrying capacity lost when we retired three single-hulled barges from service at the end of 2004, as mandated by OPA 90. The Energy 8701, one of the previously retired tank barges, was reactivated in October 2006 based on Coast Guard approval of an extended OPA 90 retirement date, which reversed the early retirement of approximately 86,000 barrels of fleet capacity. During 2006, we completed the retrofit of two additional 6,100 horsepower tugs under our first TTB newbuild program, thus finalizing the retrofit of a total of four 6,100 horsepower tugs.

In September 2005, we announced the commencement of our second TTB newbuild program. Our second TTB newbuild program consists of vessel construction and conversion contracts with three domestic shipyards to build three 60,000-barrel double-hulled tank barges and retrofit four 3,000 horsepower ocean-going tugs that were purchased in July 2006. We have delivered six vessels under this program. Three retrofitted ocean-going tugs, the Michigan Service, Huron Service, and Superior Service, and three newbuild double-hulled tank barges, the Energy 6506, Energy 6507 and Energy 6508 were placed in service on various dates during late 2007 and early 2008. The remaining vessel to be delivered under this program, the retrofitted ocean-going tug, Erie Service, is expected to be placed in service during the second quarter of 2008.

The following tables provide information, as of February 15, 2008, regarding the tugs and tank barges that we now own and operate, as well as one additional tug currently being retrofitted.

Our first and second TTB newbuild programs included the retrofitting of a total of eight tugs that were acquired in 2004, 2005 and 2006. These vessels were significantly improved and modernized to accommodate our newbuild double-hulled tank barges. The ocean-going tug, Erie Service, is currently being retrofitted at a domestic shipyard under our second TTB newbuild program and is expected to be placed in service during the second quarter of 2008.

Customers and Charter Terms

Major oil companies, large independent oil and gas exploration, development and production companies and large oil service companies constitute the majority of our customers for our offshore support services, while refining, marketing and trading companies constitute the majority of our customers for our TTB services. The percentage of revenues attributable to a customer in any particular year depends on the level of oil and natural gas exploration, development and production activities undertaken or refined petroleum products or crude oil transported by a particular customer, the availability and suitability of our vessels for the customer’s projects or products and other factors, many of which are beyond our control. We enter into a variety of contract arrangements with our customers, including spot and time charters, COAs, consecutive voyage contracts and, occasionally, bareboat charters. Our contracts are obtained through competitive bidding or, with established customers, through negotiation. For the year ended December 31, 2007, Military Sealift Command accounted for more than 10% our total revenues. For a discussion of significant customers in prior periods, see note 13 to our consolidated financial statements.

Most of the contracts for our OSVs contain early termination options in favor of the customer; however, some have early termination penalties designed to discourage the customers from exercising such options. Our tank barges have historically operated under time charters or COAs commensurate with market conditions. However, since the non-renewal of our five-year COA with Amerada Hess, which expired March 31, 2006, we have primarily operated under time charter contracts. Since we commenced operations, our OSVs have performed services for more than 90 different customers, and our tugs and tank barges have performed services for more than 250 different customers. Because of the variety and number of customers historically using the services of our fleet, and the approximate equilibrium between supply and demand in both the OSV and TTB markets, we believe that the loss of any one customer would not have a material adverse effect on our business.

Because of our successful proprietary newbuild designs, charterers have contacted us in certain circumstances to construct vessels with features designed to meet their needs. In such circumstances, we have generally contracted these specially designed vessels for three to five years, with renewal options, before construction is completed. Although we will design vessels to meet the specific needs of a charterer, we ensure in our design that customization does not preclude efficient operation of these vessels for other customers, for other purposes or in other situations.

Competition

We operate in a highly competitive industry including competitors with conventional OSVs, competitors with new generation OSVs and MPSVs and competitors in the TTB business with both single-hulled and double-hulled tank barges. Competition in the OSV and

Index to Financial Statements

domestic ocean-going TTB segments of the marine transportation industry primarily involves factors such as:

•

quality and capability of the vessels and crew members;

•

vessel availability and ability to meet the customer’s schedule;

•

safety record;

•

reputation;

•

price; and

•

experience.

All but three of our existing vessels are U.S.-flagged and are qualified under the Jones Act to engage in domestic coastwise trade. The Jones Act restricts the ability of vessels that are not built in the United States, documented under the laws of the United States and controlled by U.S. citizens from engaging in the coastwise trade in the United States and Puerto Rico. Nearly all of the cargo transportation services provided by our vessels, in both of our fleets, constitute coastwise trade as defined by the Jones Act. Consequently, competition for our services is largely restricted to other U.S. vessel owners and operators. Two of our four MPSVs will not have Jones Act privileges. See “—Environmental and Other Governmental Regulation” for a more detailed discussion of the Jones Act.

We believe that only about 36% of the new generation OSVs currently operating in the GoM are owned by publicly-traded companies. We believe we operate the second largest fleet of new generation OSVs in the GoM, and are the only publicly traded company with a significant fleet of U.S.-flagged, new generation OSVs. In contrast, approximately 51% of the conventional OSVs operating on the Continental Shelf of the GoM are owned by publicly-traded companies. We operate one of the largest tank barge fleets in Puerto Rico and believe that we are one of the largest transporters by tank barge of petroleum products in New York Harbor, a market that has a fairly even distribution among the top six competitors. All but two of our direct competitors in our segment of the TTB industry are privately held.

We do not anticipate significant competition in the near term from pipelines as an alternative method of petroleum product delivery in the northeastern United States or Puerto Rico. No pipelines are currently under construction that could provide significant competition to tank barges in the northeastern United States or Puerto Rico, nor are any new pipelines likely to be built in the near future due to cost constraints and logistical and environmental requirements.

Although some of our principal competitors are larger and may have greater financial resources and, with respect to OSVs and MPSVs, extensive international operations, we believe that our operating capabilities and reputation enable us to compete effectively with other fleets in the market areas in which we operate. In particular, we believe that the relatively young age and advanced features of our OSVs and MPSVs provide us with a competitive advantage. The ages of our new generation OSVs range from four years to ten years, while the average age of the industry’s conventional U.S.-flagged OSV fleet is approximately 27 years. We believe that many more of these older vessels will be retired in the next few years.

Index to Financial Statements

Worldwide competition for new generation vessels has been impacted in recent years by the increase in newbuild OSVs placed in service and greater interest in deep well, deepwater and ultra-deepwater drilling activity.

Competition for MPSVs differs from OSVs in that MPSVs that do not have coastwise trade privileges might be permitted to operate in the U.S. GoM, provided they do not engage in certain activities that are reserved for Jones Act qualified vessels. Consequently, our MPSVs may face more competition from foreign flag vessels in the GoM than do our OSVs. In addition, some potential MPSV customers are also owners of MPSVs that will compete with our vessels. Our OSVs, by contrast, are usually contracted by oil companies which do not own their own vessels and therefore do not compete with us. In addition, our MPSVs will compete internationally, as opposed to only in the U.S. GoM.

Environmental and Other Governmental Regulation

Our operations are significantly affected by a variety of federal, state, local and international laws and regulations governing worker health and safety and the manning, construction and operation of vessels. Certain U.S. governmental agencies, including the Department of Homeland Security and agencies under its auspices (such as the U.S. Coast Guard and the U.S. Customs and Border Protection), the National Transportation Safety Board, and the Maritime Administration of the U.S. Department of Transportation, have jurisdiction over our operations. In addition, private industry organizations such as the American Bureau of Shipping oversee aspects of our business. The U.S. Coast Guard and the National Transportation Safety Board establish safety criteria and are authorized to investigate vessel accidents and recommend improved safety standards, requirements, tonnage requirements and restrictions, hull and shafting requirements and vessel documentation. Coast Guard regulations require that each of our vessels be drydocked for inspection at least twice within a five-year period.

Under the Jones Act, the privilege of transporting merchandise or passengers for hire in the coastwise trade in U.S. domestic waters is restricted to only those vessels that are controlled by U.S. citizens and are built in and documented under the laws of the United States. To engage in coastwise trade, a corporation is not considered a U.S. citizen unless, among other things:

•

the corporation is organized under the laws of the United States or of a state, territory or possession of the United States;

•

at least 75% of the ownership of voting interests with respect to its capital stock is held by U.S. citizens;

•

the corporation’s chief executive officer, president and chairman of the board are U.S. citizens; and

•

no more than a minority of the number of directors necessary to constitute a quorum for the transaction of business are non-U.S. citizens.

We meet all of the foregoing requirements. If we should fail to comply with these requirements, our vessels would lose their eligibility to engage in coastwise trade within U.S. domestic waters. To facilitate compliance, our certificate of incorporation:

•

limits ownership by non-U.S. citizens of any class of our capital stock (including our common stock) to 20%, so that foreign ownership will not exceed the 25% permitted;

Index to Financial Statements

•

permits withholding of dividends and suspension of voting rights with respect to any shares held by non-U.S.citizens that exceed 20%;

•

permits a stock certification system with two types of certificates to aid tracking of ownership;

•

permits our board of directors to redeem any shares held by non-U.S. citizens that exceed 20%; and

•

permits our board of directors to make such determinations to ascertain ownership and implement such measures as reasonably may be necessary.

Jones Act restrictions have been challenged by interests seeking to facilitate foreign competition for coastwise trade. Historically, their efforts have been defeated by large margins when considered by the U.S. Congress. In addition, in the interest of national defense, the Secretary of Homeland Security may suspend the citizen requirements of the Jones Act. Should foreign competition be permitted to enter the U.S. coastwise market to any significant extent, it could have an adverse effect on the U.S. marine industry and on us.

Our operations are also subject to a variety of federal, state, local and international laws and regulations regarding the discharge of materials into the environment or otherwise relating to environmental protection. The requirements of these laws and regulations have become more complex and stringent in recent years and may, in certain circumstances, impose strict liability, rendering a company liable for environmental damages and remediation costs without regard to negligence or fault on the part of such party. Aside from possible liability for damages and costs including natural resource damages associated with releases of oil or hazardous materials into the environment, such laws and regulations may expose us to liability for the conditions caused by others or even acts of ours that were in compliance with all applicable laws and regulations at the time such acts were performed. Failure to comply with applicable laws and regulations may result in the imposition of administrative, civil and criminal penalties, revocation of permits, issuance of corrective action orders and suspension or termination of our operations. Moreover, it is possible that changes in the environmental laws, regulations or enforcement policies that impose additional or more restrictive requirements or claims for damages to persons, property, natural resources or the environment could result in substantial costs and liabilities to us. We believe that we are in substantial compliance with currently applicable environmental laws and regulations.

OPA 90 and regulations promulgated pursuant thereto impose a variety of regulations on “responsible parties” related to the prevention and/or reporting of oil spills and liability for damages resulting from such spills. A “responsible party” includes the owner or operator of an onshore facility, pipeline or vessel or the lessee or permittee of the area in which an offshore facility is located. OPA 90 assigns liability to each responsible party for oil removal costs and a variety of public and private damages. Under OPA 90, as amended by the Coast Guard and Maritime Transportation Act of 2006, “tank vessels” of over 3,000 gross tons that carry oil or other hazardous materials in bulk as cargo, a term, which includes our tank barges, are subject to liability limits of (i) for a single-hulled vessel, the greater of $3,000 per gross ton or $22.0 million or (ii) for a tank vessel other than a single-hulled vessel, the greater of $1,900 per gross ton or $16.0 million. “Tank vessels” of 3,000 gross tons or less are subject to liability limits of (i) for a single-hulled vessel, $6.0 million or (ii) for a tank vessel other than a single-hulled vessel, $4.0 million. For any vessels, other than “tank vessels,” that are subject to OPA

Index to Financial Statements

90, the liability limits are the greater of $950 per gross ton or $800,000. A party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconduct or resulted from violation of a federal safety, construction or operating regulation. In addition, there are no liability limits for vessels carrying crude oil from a well situated on the Continental Shelf. If the party fails to report a spill or to cooperate fully in the cleanup, the liability limits likewise do not apply and certain defenses may not be available. Moreover, OPA 90 imposes on responsible parties the need for proof of financial responsibility to cover at least some costs in a potential spill. As required, we have provided satisfactory evidence of financial responsibility to the U.S. Coast Guard for all of our vessels over 300 tons.

OPA 90 also imposes ongoing requirements on a responsible party, including preparedness and prevention of oil spills, preparation of an oil spill response plan and proof of financial responsibility (to cover at least some costs in a potential spill) for vessels in excess of 300 gross tons. We have engaged the National Response Corporation to serve as our independent contractor for purposes of providing stand-by oil spill response services in all geographical areas of our fleet operations. In addition, our Oil Spill Response Plan has been approved by the U.S. Coast Guard.

OPA 90 mandates that all single-hulled tank vessels operating in U.S. waters be removed from petroleum transportation service according to a set time schedule. Data provided by a U.S. Coast Guard report dated September 2001 indicated that 5.5 million barrels of single-hulled tank barge capacity would be retired by 2005 and an additional 3.5 million barrels by 2010, as mandated by OPA 90. According to the report, this represented on a cumulative basis as of each such retirement date, 32% and 52%, respectively, of the total 17.2 million barrel single-hulled tank barge capacity that existed in 2001. OPA 90 also requires that all newly-built tank vessels used in the transportation of petroleum products be built with double hulls and provides for a phase-out period for existing single hull vessels. We previously retired from service three single-hulled tank barges at the end of 2004 pursuant to OPA 90. One of the three single-hulled barges, the Energy 8701, returned to service during 2006 after a re-measurement conducted by the U.S. Coast Guard and recertification extending its retirement date to 2015. Currently, nine of our tank barges are double-hulled and are not subject to OPA 90 retirement dates. Ten of our 12 single-hulled tank barges are not required under OPA 90 to be retired or double-hulled prior to January 1, 2015. The two other single-hulled tank barges are required to be retired from service in 2009.

Modifying or replacing existing vessels to provide for double hulls will be required of all single-hulled tank barges and tankers in the industry by the year 2015. We are in a favorable position concerning this provision because a significant number of vessels in our fleet of tank barges measure less than 5,000 gross tons. Vessels of such tonnage may continue to operate without double hulls through the year 2015. Under existing legal requirements, therefore, we will be required to modify or retire from service only two of our existing single-hulled tank barges before 2015. However, if there are changes in the law that accelerate the time frame for retirement of such vessels, or if customer policies or preferences that mandate the use of double-hulled vessels become significantly more prevalent, absent our implementation of an additional replacement or newbuild program, such changes in law or in customer mandates could adversely affect our results of operations and financial condition.

The Clean Water Act imposes strict controls on the discharge of pollutants into the navigable waters of the United States. The Clean Water Act also provides for civil, criminal

Index to Financial Statements

and administrative penalties for any unauthorized discharge of oil or other hazardous substances in reportable quantities and imposes liability for the costs of removal and remediation of an unauthorized discharge. Many states have laws that are analogous to the Clean Water Act and also require remediation of accidental releases of petroleum in reportable quantities. Our OSVs routinely transport diesel fuel to offshore rigs and platforms and also carry diesel fuel for their own use. Our OSVs also transport bulk chemical materials used in drilling activities and liquid mud, which contain oil and oil by-products. In addition, our tank barges are specifically engaged to transport a variety of petroleum products. We maintain response plans as required by the Clean Water Act to address potential oil and fuel spills on either our vessels or our shore-base facility.

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, also known as “CERCLA” or “Superfund,” and similar laws impose liability for releases of hazardous substances into the environment. CERCLA currently exempts crude oil from the definition of hazardous substances for purposes of the statute, but our operations may involve the use or handling of other materials that may be classified as hazardous substances. CERCLA assigns strict liability to each responsible party for all response costs, as well as natural resource damages and thus we could be held liable for releases of hazardous substances that resulted from operations by third parties not under our control or for releases associated with practices performed by us or others that were standard in the industry at the time.

The Resource Conservation and Recovery Act regulates the generation, transportation, storage, treatment and disposal of onshore hazardous and non-hazardous wastes and requires states to develop programs to ensure the safe disposal of wastes. We generate non-hazardous wastes and small quantities of hazardous wastes in connection with routine operations. We believe that all of the wastes that we generate are handled in all material respects in compliance with the Resource Conservation and Recovery Act and analogous state statutes.

In addition to laws and regulations affecting us directly, our operations are also influenced by laws, regulations and policies which affect our customers’ drilling programs and the oil and natural gas industry as a whole.

The Outer Continental Shelf Lands Act gives the federal government broad discretion to regulate the release of offshore resources of oil and natural gas. Because our operations rely primarily on offshore oil and natural gas exploration, development and production, if the government were to exercise its authority under the Outer Continental Shelf Lands Act to restrict the availability of offshore oil and natural gas leases, such an action would have a material adverse effect on our financial condition and results of operations.

We currently have in place protection and indemnity insurance that includes coverage for pollution incidents. Our OSVs have $5 million in primary insurance coverage for such offshore pollution incidents, with an additional $150 million in excess umbrella coverage. In addition, our tugs and tank barges have insurance coverage for oil spills with a coverage limit of $1 billion.

Both of our principal office locations in Covington, Louisiana and Brooklyn, New York, our shore-base facility in Port Fourchon, Louisiana, our field office in Trinidad, as well as all of our

Index to Financial Statements

new generation vessels in our OSV fleet and a majority of our vessels in our TTB fleet, are certified to the standards of the ISM Code for the safe management and operation of ships and for pollution prevention. In addition, our OSVs, domestically and internationally, participate in the U.S. Coast Guard’s Streamlined Inspection Program (SIP), which ensures the overall readiness level of our vessel lifesaving and other critical safety and emergency systems. We believe that our voluntary attainment and maintenance of these certifications and participation in these programs provides evidence of our commitment to operate in a manner that minimizes any impact on the environment from our fleet operations. During 2007, the Environmental Management System of HOS Port was certified to ISO 14001:2004 Standards by the American Bureau of Shipping.

RISK FACTORS

Our results of operations and financial condition can be adversely affected by numerous risks. You should carefully consider the risks described below as well as the other information we have provided in this Annual Report on Form 10-K. The risks described below are not the only ones we face. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.

Demand for our OSV services substantially depends on the level of activity in offshore oil and gas exploration, development and production.

The level of offshore oil and gas exploration, development and production activity has historically been volatile and is likely to continue to be so in the future. The level of activity is subject to large fluctuations in response to relatively minor changes in a variety of factors that are beyond our control, including:

•

changes in capital spending budgets by our customers;

•

unavailability of drilling rigs in the GOM, our principle operating area;

•

prevailing oil and natural gas prices and expectations about future prices and price volatility;

•

the cost of offshore exploration for, and production and transportation of, oil and natural gas;

•

worldwide demand for oil and natural gas;

•

consolidation of oil and gas and oil service companies operating offshore;

•

availability and rate of discovery of new oil and natural gas reserves in offshore areas;

•

local and international political and economic conditions and policies;

•

technological advances affecting energy production and consumption;

•

weather conditions;

•

environmental regulation; and

•

the ability of oil and gas companies to generate or otherwise obtain funds for exploration and production.

We expect levels of oil and gas exploration, development and production activity to continue to be volatile and affect the demand for our OSVs.

A prolonged, material downturn in oil and natural gas prices is likely to cause a substantial decline in expenditures for exploration, development and production activity, which would likely result in a corresponding decline in the demand for OSVs and MPSVs and thus decrease the utilization and dayrates of our OSVs and MPSVs. Such decreases could have a material adverse effect on our financial condition and results of operations. Moreover, increases in oil and natural gas prices and higher levels of expenditure by oil and gas companies for exploration, development and production may not necessarily result in increased demand for our OSVs and MPSVs.

Index to Financial Statements

Increases in the supply of vessels could decrease dayrates.

Certain of our competitors have announced plans to construct new OSVs to be deployed in domestic and foreign locations. A remobilization to the GoM oilfield of U.S.-flagged OSVs currently operating in other regions or in non-oilfield applications would result in an increase in OSV capacity in our primary market. Additionally, construction of double-hulled, ocean-going tank barges in sufficient size and number to exceed the replacement of the single-hulled tank barges that have been or still need to be retired under OPA 90 would create an increase in ocean-going tank barge capacity. Further, a repeal, suspension or significant modification of the Jones Act, or the administrative erosion of its benefits, permitting OSVs or tank barges that are either foreign-flagged, foreign-built, foreign-owned, foreign-controlled or foreign-operated to engage in the U.S. coastwise trade, would also result in an increase in capacity. Any increase in the supply of OSVs, whether through new construction, refurbishment or conversion of vessels from other uses, remobilization or changes in law or its application, could not only increase competition for charters and lower utilization and dayrates, which would adversely affect our revenues and profitability, but could also worsen the impact of any downturn in oil and natural gas prices on our results of operations and financial condition. Similarly, any increase in the supply of ocean-going tank barges, could not only increase competition for charters and lower utilization and dayrates, which could negatively affect our revenues and profitability, but could also worsen the impact of any reduction in domestic consumption of refined petroleum products or crude oil on our results of operations and financial condition.

Intense competition in our industry could reduce our profitability and market share.

Contracts for our OSVs and tank barges are generally awarded on an intensely competitive basis. The most important factors determining whether a contract will be awarded include:

•

quality and capability of the vessels and crew members;

•

vessel availability and ability to meet the customer’s schedule;

•

safety record;

•

reputation;

•

price; and

•

experience.

Some of our competitors, including diversified multinational companies in the OSV segment, have substantially greater financial resources and larger operating staffs than we do. They may be better able to compete in making vessels available more quickly and efficiently, meeting the customer’s schedule and withstanding the effect of declines in dayrates and utilization rates. They may also be better able to weather a downturn in the oil and gas industry. As a result, we could lose customers and market share to these competitors. Some of our competitors may also be willing to accept lower dayrates in order to maintain utilization, which can have a negative impact upon dayrates and utilization in both of our market segments.

Index to Financial Statements

The failure to successfully complete construction or conversion of our vessels or repairs, maintenance and routine drydockings on schedule and on budget and to utilize such vessels and the other vessels in our fleet at profitable levels could adversely affect our financial condition and results of operations.

We have 16 new generation OSVs and two MPSVs currently under construction, one ocean-going tug being retrofitted and two coastwise sulfur tankers currently undergoing conversion into MPSVs. We may plan to construct other such vessels as market conditions warrant. We also routinely engage shipyards to drydock our vessels for regulatory compliance and to provide repair and maintenance. Our construction projects and drydockings are subject to the risks of delay and cost overruns inherent in any large construction project, including shortages of equipment, lack of shipyard availability, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, inability to obtain necessary certifications and approvals and shortages of materials or skilled labor. Significant delays could have a material adverse effect on anticipated contract commitments or anticipated revenues with respect to vessels under construction, conversion or for other drydockings. Further, significant cost overruns or delays for vessels under construction, conversion or retrofit not adequately protected by liquidated damages provisions, in general could adversely affect our financial condition and results of operations. Moreover, customer demand for vessels currently under construction or conversion may not be as strong as we presently anticipate, and our inability to obtain contracts on anticipated terms or at all may have a material adverse effect on our revenues and profitability. In addition, our OSVs are typically chartered or hired to provide services to a specified drilling rig. A delay in the availability of the drilling rig to our customer may have an adverse impact on our utilization of the contracted vessel and thus on our financial condition and results of operations.

We have grown, and may continue to grow, through acquisitions that give rise to risks and challenges that could adversely affect our future financial results.

We regularly consider possible acquisitions of single vessels, vessel fleets and businesses that complement our existing operations to enable us to grow our business. Acquisitions can involve a number of special risks and challenges, including:

•

diversion of management time and attention from our existing business and other business opportunities;

•

delays in closing or the inability to close an acquisition for any reason, including third party consents or approvals;

•

any unanticipated negative impact on us of disclosed or undisclosed matters relating to any vessels or operations acquired;

•

any unanticipated negative impact on us of disclosed or undisclosed legal liabilities, including such things as fines or penalties imposed by governmental authorities;

•

loss or termination of employees, including costs associated with the termination or replacement of those employees;

•

assumption of debt or other liabilities of the acquired business, including litigation related to the acquired business;

•

the incurrence of additional acquisition-related debt as well as increased expenses and working capital requirements;

•

dilution of stock ownership of existing stockholders;

Index to Financial Statements

•

increased costs and efforts in connection with compliance with Section 404 of the Sarbanes-Oxley Act; and

•

substantial accounting charges for restructuring and related expenses, impairment of goodwill, amortization of intangible assets, and stock-based compensation expense.

Even if we consummate an acquisition, the process of integrating acquired operations into our own may result in unforeseen operating difficulties and costs and may require significant management attention and financial resources. In addition, integrating acquired businesses may impact the effectiveness of our internal control over financial reporting. Any of the foregoing, and other factors, could harm our ability to achieve anticipated levels of utilization and profitability from acquired vessels or businesses or to realize other anticipated benefits of acquisitions.

We can give no assurance that we will be able to identify desirable acquisition candidates or that we will be successful in entering into definitive agreements or closing such acquisitions on satisfactory terms. An inability to acquire additional vessels or businesses may limit our growth potential.

Revenues from our TTB business could be adversely affected by a decline in demand for domestic refined petroleum products and crude oil or a change in existing methods of delivery in response to insufficient availability of TTB services and other conditions.

A reduction in domestic consumption of refined petroleum products or crude oil may adversely affect the revenues of our TTB business and, therefore, our financial condition and results of operation. Weather conditions also affect demand for our TTB services. For example, a mild winter may reduce demand for heating oil in the northeastern United States.

Moreover, alternative methods of delivery of refined petroleum products or crude oil may develop as a result of insufficient availability of TTB services, the cost of compliance with homeland security, environmental regulations or increased liabilities connected with the transportation of refined petroleum products and crude oil. For example, long-haul transportation of refined petroleum products and crude oil is generally less costly by pipeline than by tank barge. While there are significant impediments to building new pipelines, such as high capital costs and environmental concerns, entities may propose new pipeline construction to meet demand for petroleum products. To the extent new pipeline segments are built or existing pipelines converted to carry petroleum products, such activity could have an adverse effect on our ability to compete in particular markets.

The early termination of contracts on our vessels could have an adverse effect on our operations.

Most of the long-term contracts for our vessels contain early termination options in favor of the customer; however, some have early termination penalties or other provisions designed to discourage the customers from exercising such options. We cannot assure that our customers would not choose to exercise their termination rights in spite of such penalties or the threat of litigation with us. Until replacement of such business with other customers, any termination could temporarily disrupt our business or otherwise adversely affect our financial condition and results of operations. We might not be able to replace such business on economically equivalent terms.

Index to Financial Statements

We are subject to complex laws and regulations, including environmental regulations, that can adversely affect the cost, manner or feasibility of doing business.

Stringent federal, state, local and foreign laws and regulations governing worker health and safety and the manning, construction and operation of vessels significantly affect our operations. Many aspects of the marine industry are subject to extensive governmental regulation by the United States Coast Guard, the National Transportation Safety Board and the United States Customs Service, and their foreign equivalents, and to regulation by private industry organizations such as the American Bureau of Shipping. The Coast Guard and the National Transportation Safety Board set safety standards and are authorized to investigate vessel accidents and recommend improved safety standards, while the Customs Service is authorized to inspect vessels at will. Our operations are also subject to federal, state, local and international laws and regulations that control the discharge of pollutants into the environment or otherwise relate to environmental protection. Compliance with such laws, regulations and standards may require installation of costly equipment, increased manning, or operational changes. While we endeavor to comply with all applicable laws, we might not and our failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions, imposition of remedial obligations or the suspension or termination of our operations. Some environmental laws impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault. These laws and regulations may expose us to liability for the conduct of, or conditions caused by, others, including charterers. Moreover, these laws and regulations could change in ways that substantially increase costs that we may not be able to pass along to our customers. Any changes in laws, regulations or standards that would impose additional requirements or restrictions could adversely affect our financial condition and results of operations.

We are also subject to the Merchant Marine Act of 1936, which provides that, upon proclamation by the President of a national emergency or a threat to the security of the national defense, the Secretary of Transportation may requisition or purchase any vessel or other watercraft owned by United States citizens (which includes United States corporations), including vessels under construction in the United States. If one of our OSVs, tugs or tank barges were purchased or requisitioned by the federal government under this law, we would be entitled to be paid the fair market value of the vessel in the case of a purchase or, in the case of a requisition, the fair market value of charter hire. However, if one of our tugs is requisitioned or purchased and its associated tank barge is left idle, we would not be entitled to receive any compensation for the lost revenues resulting from the idled barge. We would also not be entitled to be compensated for any consequential damages we suffer as a result of the requisition or purchase of any of our OSVs, tugs or tank barges. The purchase or the requisition for an extended period of time of one or more of our OSVs, tugs or tank barges could adversely affect our results of operations and financial condition.

Finally, we are subject to and depend upon the Merchant Marine Act of 1920, commonly referred to as the Jones Act, which requires that vessels engaged in coastwise trade to carry cargo between U.S. ports be documented under the laws of the United States and be controlled by U.S. citizens. To ensure that we are determined to be a U.S. citizen as defined under these laws, our certificate of incorporation contains certain restrictions on the ownership of our capital stock by non-U.S. citizens and establishes certain mechanisms to

Index to Financial Statements

maintain compliance with these laws. If we are determined at any time not to be in compliance with these citizenship requirements, our vessels would become ineligible to engage in the coastwise trade in U.S. domestic waters, and our business and operating results would be adversely affected. The Jones Act’s provisions restricting coastwise trade to vessels controlled by U.S. citizens have recently been circumvented by foreign interests that seek to engage in trade reserved for vessels controlled by U.S. citizens and otherwise qualifying for coastwise trade. Legal challenges against such actions are difficult, costly to pursue and are of uncertain outcome. To the extent such efforts are successful and foreign competition is permitted, such competition could have a material adverse effect on domestic companies in the offshore service vessel industry and on our financial condition and results of operations. In addition, in the interest of national defense, the Secretary of Homeland Security is authorized to suspend the coastwise trading restrictions imposed by the Jones Act on vessels not controlled by U.S. citizens. Such a waiver was issued following Hurricane Katrina and was in effect on a temporary basis for tank vessels that carried petroleum products.

Our business involves many operating risks that may disrupt our business or otherwise result in substantial losses, and insurance may be unavailable or inadequate to protect us against these risks.

Our vessels are subject to operating risks such as:

•

catastrophic marine disaster;

•

adverse weather and sea conditions;

•

mechanical failure;

•

collisions or allisions;

•

oil and hazardous substance spills;

•

navigation errors;

•

acts of God; and

•

war and terrorism.

The occurrence of any of these events may result in damage to or loss of our vessels and their tow or cargo or other property and injury to passengers and personnel. If any of these events were to occur, we could be exposed to liability for resulting damages and possible penalties, that pursuant to typical marine indemnity policies, we must pay and then seek reimbursement from our insurer. Affected vessels may also be removed from service and thus be unavailable for income-generating activity. While we believe our insurance coverage is at adequate levels and insures us against risks that are customary in the industry, we may be unable to renew such coverage in the future at commercially reasonable rates. Moreover, existing or future coverage may not be sufficient to cover claims that may arise. Finally, we do not maintain insurance for loss of income resulting from a marine casualty.

Our expansion of operations into international markets and shipyard activities in foreign shipyards subjects us to risks inherent in conducting business internationally.

Over the past several years we have derived an increasing portion of our revenues from foreign sources. In addition, certain of our newbuild construction, shipyard repair and

Index to Financial Statements

procurement activities are being conducted with foreign vendors. We therefore face risks inherent in conducting business internationally, such as legal and governmental regulatory requirements, potential vessel seizure or nationalization of assets, import-export quotas or other trade barriers, difficulties in collecting accounts receivable and longer collection periods, political and economic instability, kidnapping of or assault on personnel, adverse tax consequences, difficulties and costs of staffing international operations, currency exchange rate fluctuations and language and cultural differences. All of these risks are beyond our control and difficult to insure against. We cannot predict the nature and the likelihood of any such events. If such an event should occur, however, it could have a material adverse effect on our financial condition and results of operations.

Future results of operations depend on the long-term financial stability of our customers.

Many of the contracts we enter into for our vessels are full utilization contracts with initial terms ranging from one to five years. We enter into these long-term contracts with our customers based on a credit assessment at the time of execution. Our financial condition in any period may therefore depend on the long-term stability and creditworthiness of our customers. We can provide no assurance that our customers will fulfill their obligations under our long-term contracts and the insolvency or other failure of a customer to fulfill its obligations under such contract could adversely affect our financial condition and results of operations.

We may be unable to attract and retain qualified, skilled employees necessary to operate our business.

Our success depends in large part on our ability to attract and retain highly skilled and qualified personnel. Our inability to hire, train and retain a sufficient number of qualified employees could impair our ability to manage, maintain and grow our business.

In crewing our vessels, we require skilled employees who can perform physically demanding work. As a result of the volatility of the oil and gas industry and the demanding nature of the work, potential vessel employees may choose to pursue employment in fields that offer a more desirable work environment at wage rates that are competitive with ours. With a reduced pool of workers, it is possible that we will have to raise wage rates to attract workers and to retain our current employees such as occurred in 2006. If we are not able to increase our service rates to our customers to compensate for wage-rate increases, our financial condition and results of operations may be adversely affected. If we are unable to recruit qualified personnel we may not be able to operate our vessels at full utilization, which would adversely affect our results of operations.

Our employees are covered by federal laws that may subject us to job-related claims in addition to those provided by state laws.

Some of our employees are covered by provisions of the Jones Act, the Death on the High Seas Act and general maritime law. These laws preempt state workers’ compensation laws and permit these employees and their representatives to pursue actions against employers for job-related incidents in federal courts based on tort theories. Because we are not generally protected by the damage limits imposed by state workers’ compensation statutes, we may have greater exposure for any claims made by these employees.

Index to Financial Statements

Our success depends on key members of our management, the loss of whom could disrupt our business operations.

We depend to a large extent on the efforts and continued employment of our executive officers and key management personnel. We do not maintain key-man insurance. The loss of services of one or more of our executive officers or key management personnel could have a negative impact on our financial condition and results of operations.

Restrictions contained in the indenture governing our 6.125% Senior Notes due 2014 and in the agreement governing our revolving credit facility may limit our ability to obtain additional financing and to pursue other business opportunities.

Covenants contained in the indenture governing our 6.125% Senior Notes due 2014 and in the agreement governing our revolving credit facility require us to meet certain financial tests, which may limit or otherwise restrict:

•

our flexibility in operating, planning for, and reacting to changes, in our business;

•

our ability to dispose of assets, withstand current or future economic or industry downturns and compete with others in our industry for strategic opportunities; and

•

our ability to obtain additional financing for working capital, capital expenditures, including our newbuild programs, acquisitions, general corporate and other purposes.

We have high levels of fixed costs that will be incurred regardless of our level of business activity.

Our business has high fixed costs, and downtime or low productivity due to reduced demand, weather interruptions or other causes can have a significant negative effect on our operating results and financial condition.

If we are required to retire our existing single-hulled tank barges earlier than anticipated due to either regulatory or other requirements, it could adversely affect our business.

OPA 90 requires that all newly-built tank vessels used in the transportation of petroleum products be built with double hulls and provides for a phase-out period for existing single-hulled vessels. Modifying or replacing existing vessels to provide for double hulls will be required for all tank barges and tankers in the industry by the year 2015. A significant number of vessels in our tank barge fleet measure less than 5,000 gross tons. Under current law, certain of our vessels may continue to operate without double hulls through 2014. However, if there are changes in the law that accelerate the time frame for retirement of such vessels, or if customer policies or preferences that mandate the use of double-hulled vessels become significantly more prevalent, absent our implementation of a more aggressive replacement or newbuild program, such changes in law or in customer mandates could adversely affect our results of operations and financial condition.

Our revenues and operating results may vary significantly from quarter to quarter due to a number of factors such as volatility in our vessel dayrates, changes in utilization, vessel incidents and other unforeseen matters. Many of these factors that may cause our actual financial results to vary from our publicly disclosed earnings guidance and forecasts are outside of our control.

Index to Financial Statements

Our actual financial results might vary from those anticipated by us or by securities analysts and investors, and these variations could be material. From time to time we publicly provide earnings or other forms of guidance, which reflect our projections about future dayrates, utilization, operating costs and capital structure, among other factors. These numerous assumptions may be impacted by factors that are beyond our control and might not turn out to be correct. Although we believe that the assumptions underlying our projections are reasonable, actual results could be materially different.

We are susceptible to unexpected increases in operating expenses such as materials and supplies, crew wages, maintenance and repairs, and insurance costs.

Many of our operating costs are unpredictable and vary based on events beyond our control. Our gross margins will vary based on fluctuations in our operating costs. If our costs increase or we encounter unforeseen costs, we may not be able to recover such costs from our customers, which could adversely affect our financial position, results of operations and cash flows.

We may not have the ability to raise the funds necessary to settle conversion of the 1.625% convertible senior notes or to purchase such notes upon a fundamental change or on other purchase dates as defined in the agreement, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of shares.

Upon conversion of the 1.625% convertible senior notes, we may pay a settlement amount in cash and shares of our common stock, if any, based upon a 25 trading-day observation period. In addition, on November 15, 2013, November 15, 2016 and November 15, 2021, holders of the 1.625% convertible senior notes may require us to purchase their notes for cash. We cannot assure you that we will have sufficient financial resources, or would be able to arrange financing, to pay the settlement amount in cash, or the purchase price or fundamental change purchase price for the 1.625% convertible senior notes tendered by the holders in cash. Further, our ability to pay the settlement amount in cash, or the purchase price or fundamental change purchase price for the 1.625% convertible senior notes in cash may be subject to limitations in our revolving credit facility or any other indebtedness we may have in the future. If the holders of the 1.625% convertible senior notes convert such notes or require us to repurchase them, we may seek the consent of our lenders or attempt to refinance the debt, but there can be no assurance that we will be able to do so. Failure by us to pay the settlement amount upon conversion or purchase the notes when required will result in an event of default with respect to the notes, which may also result in the acceleration of our other indebtedness.

The convertible note hedge and warrant transactions may affect the value of our common stock.

In connection with the original issuance of the 1.625% convertible senior notes, we entered into convertible note hedge and warrant transactions with counterparties that include affiliates of the initial purchasers of the convertible senior notes. The convertible note hedge transactions are expected to reduce the potential dilution upon conversion of such notes. However, if the warrants are exercised, such exercise would mitigate some of that reduction. In connection with these hedging and warrant transactions, such counterparties or their affiliates may enter into, or may unwind, various derivatives and/or purchase or sell our common stock in secondary market transactions (and are likely to do so during any observation period related to a conversion of notes).

Index to Financial Statements

The effect, if any, of these convertible note hedge and warrant transactions or any of these hedging activities on the market price of our common stock or the convertible senior notes will depend in part on market conditions and cannot be ascertained at this time, but any of these activities could materially and adversely affect the value of our common stock.

The fundamental change purchase feature of the 1.625% convertible senior notes and provisions of our certificate of incorporation, bylaws, stockholder rights plan and Delaware law may delay or prevent an otherwise beneficial takeover attempt of our company.

The terms of the notes require us to purchase the notes for cash in the event of a fundamental change. A takeover of our company would trigger the requirement that we purchase the notes. Furthermore, our certificate of incorporation and bylaws, Delaware corporations law, and our stockholder rights plan contain provisions that could have the effect of making it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, control of us. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock and may have the effect of delaying or preventing a takeover of our company that would otherwise be beneficial to investors.

Conversion of the 1.625% convertible senior notes or exercise of the warrants issued in the warrant transactions may dilute the ownership interest of existing stockholders.

The conversion of the 1.625% convertible senior notes or exercise of some or all of the warrants we issued in the warrant transactions may dilute the ownership interests of existing stockholders. Although the convertible note hedge transactions are expected to reduce potential dilution upon conversion of the 1.625% convertible senior notes, the warrant transactions could have a dilutive effect on our earnings per share to the extent that the price of our common stock exceeds the strike price of the warrants. Any sales in the public market of our common stock issuable upon such conversion of the 1.625% convertible senior notes could adversely affect prevailing market prices of our common stock. In addition, the anticipated exercise of the warrants for shares of our common stock could depress the price of our common stock.

Operating Hazards and Insurance

The operation of our vessels is subject to various risks, such as catastrophic marine disaster, adverse weather conditions, mechanical failure, collision and navigation errors, all of which represent a threat to personnel safety and to our vessels and cargo. We maintain insurance coverage that we consider customary in the industry against certain of these risks, including, as discussed above, $1 billion in pollution insurance for the TTB fleet and $155 million of pollution coverage for the OSVs. We believe that our current level of insurance is adequate for our business and consistent with industry practice, and we have not experienced a loss in excess of our policy limits. We may not be able to obtain insurance coverage in the future to cover all risks inherent in our business, or insurance, if available, may be at rates that we do not consider to be commercially reasonable. In addition, as single-hulled tank barges increase in age, insurers may be less willing to insure and customers less willing to hire single-hulled vessels. The terms of our entry into a mutual protection and indemnity association covering marine risks relating to our TTB business allows additional premiums to be called for from time to time, and paid by association members in respect of unanticipated reserve requirements of the association.

Employees

On December 31, 2007, we had 1,092 employees, including 906 operating personnel and 186 corporate, administrative and management personnel. None of our employees are represented by a union or employed pursuant to a collective bargaining agreement or similar arrangement. We have not experienced any strikes or work stoppages, and our management believes that we continue to enjoy good relations with our employees.

Properties

Our corporate headquarters are located in Covington, Louisiana. Our primary office lease covers 23,756 square feet and has an initial term of five years, which commenced in September 2003, with two additional five-year renewal periods. In August 2005 and December 2005, we entered into agreements that increased our total office space by an additional 5,500 square feet and 4,700 square feet, respectively. In March 2008, we intend to exercise our first five-year renewal option with respect to our corporate headquarters in Covington. We also hold a one-year lease on 4,500-square-feet in a warehouse near our corporate headquarters to maintain spare parts inventory. To support our OSV operations in the GoM, we lease office and warehouse space in New Iberia, Louisiana, and a shore base facility in Port Fourchon, Louisiana operated under the name HOS Port. The New Iberia lease covers 5,000 square feet of office space and 5,000 square feet of warehouse space. This lease commenced in August 2007 and has a term of two years with one renewal option for two years. We have two facility leases for HOS Port. The first lease commenced in December 2005 and has an initial term of seven years with four additional five-year renewal periods. The second lease commenced in January 2008 and has an initial term of approximately six years with four additional five-year renewal periods. The base facility covers approximately 60 acres of land and includes approximately 2,900 linear feet of dock space and 29,893 square feet of warehouse and office space. For local support in Puerto Rico, we lease an office consisting of approximately 1,900 square feet. To support our operations in the northeastern United States, we lease office space and warehouse space in Brooklyn, New York, consisting of

Index to Financial Statements

approximately 66,760 square feet. We also lease dock space, consisting of approximately 36,000 square feet, in Brooklyn, New York. We primarily operate our TTB fleet from these New York facilities. The lease on our Brooklyn facilities is currently scheduled to expire in March 2008 and we intend to exercise a month to month extension option for that facility prior to expiration. Information regarding our fleet is set forth above in “—Offshore Supply Vessels—Our OSV Business” and “—Tugs and Tank Barges—Our Tug and Tank Barge Business”.

Seasonality of Business

Demand for our offshore support services is directly affected by the levels of offshore drilling activity. Budgets of many of our customers are based upon a calendar year, and demand for our services has historically been stronger in the second and third calendar quarters when allocated budgets are expended by our customers and weather conditions are more favorable for offshore activities. Many other factors, such as the expiration of drilling leases and the supply of and demand for oil and natural gas, may affect this general trend in any particular year. In addition, we typically have an increase in demand for our OSVs to survey and repair offshore infrastructure immediately following major hurricanes in the GoM.

Tank barge services are significantly affected by the strength of the U.S. economy, changes in weather patterns and population growth that affect the consumption of and the demand for refined petroleum products and crude oil. The TTB market, in general, is marked by steady demand over time, although such demand is seasonal and often dependent on weather conditions. Unseasonably mild winters result in significantly lower demand for heating oil in the northeastern United States, which is a significant market for our TTB services. Conversely, the summer driving season can increase demand for automobile fuel and, accordingly, the demand for our services.

We owned and operated 35 new generation OSVs as of December 31, 2007, including ten new generation OSVs that were acquired on August 8, 2007. Excluded from this data are 10 conventional OSVs that were also acquired on August 8, 2007, which we consider to be non-core assets. The averages for the year ended December 31, 2005 reflect the acquisition of the HOS Saylor and the HOS Navegante in the first quarter of 2005. The averages for the year ended December 31, 2004 give effect to the delivery of the HOS Silverstar in March 2004. The averages for the year ended December 31, 2003 reflect the acquisitions of six new generation OSVs in mid-2005 and the delivery of three newbuild OSVs on various dates throughout 2003.

(7)	Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues.

(8)	Average dayrates represent average revenue per day, which includes charter hire, crewing services and net brokerage revenues, based on the number of days during the period that the OSVs generated revenue.

(9)	Effective dayrate represents the average dayrate multiplied by the average utilization rate.

We owned and operated 20 tank barges as of December 31, 2007, including the Energy 6506 and the Energy 6507, two double-hulled tank barges delivered under our second TTB newbuild program in August 2007 and November 2007, respectively. The averages for the year ended December 31, 2006 include the Energy 8701, a previously retired tank barge that was reactivated in October 2006 following a U.S. Coast Guard approved extension of its retirement date to 2015. The averages for the year ended December 31, 2005 reflect the delivery of five double-hulled tank barges under our first TTB newbuild program, including two 135,000-barrel double-hulled tank barges in March 2005 and December 2005 and three 110,000-barrel double-hulled tank barges in July 2005, October 2005 and December 2005, respectively. As of December 31, 2004, our TTB fleet consisted of 16 vessels, of which three tank barges were retired from service by the end of 2004. The averages for the year ended December 31, 2003 give effect to our sale of the Energy 5502 on January 28, 2003 and our acquisition of the Energy 8001 on February 28, 2003.

Average dayrates represent average revenue per day, including time charters, brokerage revenue, revenues generated on a per-barrel-transported basis, demurrage, shipdocking and fuel surcharge revenue, based on the number of days during the period that the tank barges generated revenue. For purposes of brokerage arrangements, this calculation excludes that portion of revenue that is equal to the cost of in-chartering third-party equipment paid by customers.

Non-GAAP Financial Measures

We disclose and discuss EBITDA as a non-GAAP financial measure in our public releases, including quarterly earnings releases, investor conference calls and other filings with the Commission. We define EBITDA as earnings (net income) before interest, income taxes, depreciation and amortization. Our measure of EBITDA may not be comparable to similarly titled measures presented by other companies. Other companies may calculate EBITDA differently than we do, which may limit their usefulness as comparative measures.

We view EBITDA primarily as a liquidity measure and, as such, we believe that the GAAP financial measure most directly comparable to this measure is cash flows provided by operating activities. Because EBITDA is not a measure of financial performance calculated in accordance with GAAP, it should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP.

EBITDA is widely used by investors and other users of our financial statements as a supplemental financial measure that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our ability to service debt, pay deferred

Index to Financial Statements

taxes and fund drydocking charges and other maintenance capital expenditures. We also believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our cash flow generating capacity from quarter to quarter and year to year.

EBITDA is also a financial metric used by management (i) as a supplemental internal measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; (ii) as a significant criteria for annual incentive cash compensation paid to our executive officers and other shore-based employees; (iii) to compare to the EBITDA of other companies when evaluating potential acquisitions; and (iv) to assess our ability to service existing fixed charges and incur additional indebtedness.

The following table provides the detailed components of EBITDA as we define that term for the years ended December 31, 2007, 2006, 2005, 2004, and 2003 respectively (in thousands). Information for years prior to 2007 has been reclassified to conform to the 2007 presentation.

In addition, we also make certain adjustments to EBITDA for loss on early extinguishment of debt, stock-based compensation expense and interest income to compute

ratios used in certain financial covenants of our revolving credit facility with various lenders. We believe that these ratios are a material component of certain financial covenants in such credit agreements and failure to comply with the financial covenants could result in the acceleration of indebtedness or the imposition of restrictions on our financial flexibility.

The following table provides the detailed adjustments to EBITDA, as defined in our revolving credit facility for the years ended December 31, 2007, 2006, 2005, 2004 and 2003, respectively (in thousands).

Set forth below are the material limitations associated with using EBITDA as a non-GAAP financial measure compared to cash flows provided by operating activities.

•

EBITDA does not reflect the future capital expenditure requirements that may be necessary to replace our existing vessels as a result of normal wear and tear,

•

EBITDA does not reflect the interest, future principal payments and other financing-related charges necessary to service the debt that we have incurred in acquiring and constructing our vessels,

•

EBITDA does not reflect the deferred income taxes that we will eventually have to pay once we are no longer in an overall tax net operating loss carryforward position, and

•

EBITDA does not reflect changes in our net working capital position.

Management compensates for the above-described limitations in using EBITDA as a non-GAAP financial measure by only using EBITDA to supplement our GAAP results.

Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our historical consolidated financial statements and their notes included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements or as a result of certain factors such as those set forth under “Forward Looking Statements.”

General

We own and operate a fleet of 35 technologically advanced, new generation OSVs. We also own two former coastwise sulfur tankers that are being converted into MPSVs and 10 conventional OSVs that were acquired in August 2007. In addition, we have 16 new

Index to Financial Statements

generation OSVs and two MPSVs under construction with expected deliveries in 2008 through 2010. Of our 24 new generation OSVs currently operating in domestic waters, 20 are operating in the U.S. Gulf of Mexico, or GoM, and four are operating along other U.S. coastlines. Of our eleven new generation OSVs currently working in international waters, four are operating offshore Trinidad, five are operating offshore Mexico and two are operating offshore Qatar. We also own 16 ocean-going tugs and 21 ocean-going tank barges, nine of which are double-hulled. Currently, ten of our tank barges are operating in the northeastern United States, primarily New York Harbor, nine are operating in the GoM and two are operating in Puerto Rico. Except for one foreign-flagged AHTS, one foreign-flagged well stimulation vessel and one foreign-flagged conventional OSV, all of our vessels are qualified under the Jones Act to engage in U.S. coastwise trade.

We charter our OSVs on a dayrate basis, under which the customer pays us a specified dollar amount for each day during the term of the contract, pursuant to either fixed term or spot time charters. A fixed term time charter is a contract for a fixed period with a specified dayrate, generally paid monthly. Spot time charters in the OSV industry are generally charter contracts with either relatively short fixed or indefinite terms. In all time charters, spot or fixed, the vessel owner absorbs crew, insurance and repair and maintenance costs in connection with the operation of the vessel, while customers absorb all other direct operating costs. In addition, in a typical time charter, the charterer obtains the right to direct the movements and utilization of the vessel while the vessel owner retains operational control over the vessel. We have also earned revenues by providing crewing and vessel management services to other vessel owners.

All of our OSVs operate under time charters, including twelve that are chartered under long-term contracts with expiration dates ranging from September 2008 through June 2012. The long-term contracts for our supply vessels are consistent with those used in the industry and are typically either fixed for a term of one or more years or are tied to the duration of a long-term contract for a drilling rig for which the vessel provides services. These contracts generally contain, among others, provisions governing insurance, reciprocal indemnifications, performance requirements and, in certain instances, dayrate escalation terms and renewal options.

While OSVs service existing oil and gas production platforms as well as exploration and development activities, incremental OSV demand depends primarily upon the level of drilling activity, which can be influenced by a number of factors, including oil and natural gas prices and drilling budgets of exploration and production companies. As a result, utilization rates have historically been tied to oil and natural gas prices and drilling activity. However, the relatively large capital commitments, longer lead times and investment horizons associated with deepwater and deep well projects have diminished the significance of these factors compared to conventional shelf projects.

Although the demand for new generation equipment has historically been driven by deepwater, deep well and highly complex projects, we are experiencing increased demand for our vessels for all types of projects, including transition zone and shelf activity, irrespective of water depth, drilling depth or project type, and non-oil and gas production activities, including military applications. Notably, this prevailing shift in customer preference does not appear to be limited to the GoM, as we have also observed this preference in foreign areas such as Mexico, Trinidad, Brazil and West Africa.

Index to Financial Statements

Our TTB equipment transports petroleum products between U.S. ports and along the coast of Puerto Rico. We operate our ocean-going tugs and tank barges under fixed time charters, spot time charters, contracts of affreightment, or COAs, and consecutive voyage contracts. A fixed term time charter is a contract for a fixed period of time with a specified day rate, generally paid monthly. Spot time charters in the TTB industry are generally single-voyage COAs, consecutive voyage contracts, or time charter contracts with either relatively short fixed or indefinite terms. A consecutive voyage contract is a contract for the transportation of cargo for a specified number of voyages between designated ports over a fixed period of time under which we are paid based on the volume of products we deliver per voyage. Under consecutive voyage contracts, in addition to earning revenues for volumes delivered, we earn a standby hourly rate between voyages. We may also charter vessels to a third party under a bareboat charter. A bareboat charter is a “net lease” in which the charterer takes full operational control over the vessel for a specified period of time for a specified daily rate that is generally paid monthly to the vessel owner. The bareboat charterer is solely responsible for the operation and management of the vessel and must provide its own crew and pay all operating and voyage expenses. We also provide tug services to third party vessels on a periodic basis. Typically, these services include vessel docking and towage assistance.

The primary demand drivers for our TTB services are population growth, the strength of the U.S. economy, seasonal weather patterns, oil prices and competition from alternate energy sources. The TTB market, in general, is marked by steady demand over time. Our results for the first and fourth quarters of a given year are typically higher due to normal seasonal winter-weather patterns that typically result in a drop-off of activity during the second and third quarters. Because we have recently shifted nearly all of our TTB fleet from COAs to time charters and continue to diversify our services and geographical areas of operation, some of our historic seasonality for this segment should be diminished. We generally take advantage of seasonal weather patterns to prepare our TTB fleet for peak demand periods by performing our regulatory drydocking and maintenance programs during the second and third quarters. In addition, we regularly evaluate our customers’ needs and often elect to accelerate scheduled drydockings to take advantage of certain market opportunities.

As the most recent major OPA 90 milestone approached on January 1, 2005 and since that date, customer demand for double-hulled equipment has led to increased dayrates for this equipment. We are actively working to ensure that our fleet is well positioned to take advantage of emerging market opportunities as they develop. To expand our geographic market area and current service offering, we are now operating vessels from our TTB fleet in the GoM. These vessels are being used for the transportation of petroleum products and, more recently, ethanol. In recent years, we have also been successful in deploying our vessels in non-traditional TTB services, such as support of deepwater well testing and other specialty applications for our upstream customers. We now have 16 of our tank barges operating under time charters, including seven that are chartered under long-term contracts with expiration dates ranging from April 2008 through August 2009.

Our operating costs are primarily a function of fleet size and utilization levels. The most significant direct operating costs are wages paid to vessel crews, maintenance and repairs and marine insurance. Because most of these expenses are incurred regardless of vessel utilization, our direct operating costs as a percentage of revenues may fluctuate considerably with changes in dayrates and utilization.

Index to Financial Statements

In addition to the operating costs described above, we incur fixed charges related to the depreciation of our fleet and amortization of costs for routine drydock inspections and maintenance and repairs necessary to ensure compliance with applicable regulations and to maintain certifications for our vessels with the U.S. Coast Guard and various classification societies. The aggregate number of drydockings and other repairs undertaken in a given period determines the level of maintenance and repair expenses and marine inspection amortization charges. We generally capitalize costs incurred for drydock inspection and regulatory compliance and amortize such costs over the period between such drydockings, typically 30 or 60 months. Applicable maritime regulations require us to drydock our vessels twice in a five-year period for inspection and routine maintenance and repair. If we undertake a large number of drydockings in a particular fiscal period, comparative results may be affected.

Critical Accounting Policies

Our consolidated financial statements included in this Annual Report on Form 10-K have been prepared in accordance with accounting principles generally accepted in the United States. In many cases, the accounting treatment of a particular transaction is specifically dictated by generally accepted accounting principles. In other circumstances, we are required to make estimates, judgments and assumptions that we believe are reasonable based upon available information. We base our estimates and judgments on historical experience and various other factors that we believe are reasonable based upon the information available. Actual results may differ from these estimates under different assumptions and conditions. We believe that of our significant accounting policies discussed in note 2 to our consolidated financial statements, the following may involve estimates that are inherently more subjective.

Purchase Accounting. Purchase accounting requires extensive use of estimates and judgments to allocate the cost of an acquired enterprise to the assets acquired and liabilities assumed. The cost of each acquired operation is allocated to the assets acquired and liabilities assumed based on their estimated fair values. These estimates are revised during an allocation period as necessary when, and if, information becomes available to further define and quantify the value of the assets acquired and liabilities assumed. For example, costs related to the recertification of acquired vessels that are drydocked within the allocation period immediately following the acquisition of such vessels are reflected as an adjustment to the value of the vessels acquired and the liabilities assumed related to the drydocking. The adjusted basis of the vessel is depreciated over the estimated useful life of the vessel. The allocation period does not exceed one year from the date of the acquisition. To the extent additional information to refine the original allocation becomes available during the allocation period, the allocation of the purchase price is adjusted. For example, if an acquired vessel was subsequently disposed of within the allocation period, the sales price of the vessel would be used to adjust the original assigned value to the vessel at the date of acquisition such that no gain or loss would be recognized upon disposition during the allocation period. If information becomes available after the allocation period, those items are reflected in operating results.

Carrying Value of Vessels. We depreciate our tugs, tank barges, and OSVs over estimated useful lives of 14 to 25 years, three to 25 years and 20 to 25 years, respectively. Effective January 1, 2007, we prospectively modified our assumptions for estimated salvage

Index to Financial Statements

values for our marine equipment. Salvage values for marine equipment are now estimated to range between 5% and 25% of the originally recorded cost, depending on vessel type. The useful lives used for single-hulled tank barges are based on their classification under OPA 90, and for double-hulled tank barges it is 25 years. In assigning depreciable lives to these assets, we have considered the effects of both physical deterioration largely caused by wear and tear due to operating use and other economic and regulatory factors that could impact commercial viability. To date, our experience confirms that these policies are reasonable, although there may be events or changes in circumstances in the future that indicate that recovery of the carrying amount of a vessel might not be possible. Examples of events or changes in circumstances that could indicate that the recoverability of a vessel’s carrying amount should be assessed might include a change in regulations such as OPA 90, a significant decrease in the market value of a vessel and current period operating or cash flow losses combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with a vessel. If events or changes in circumstances as set forth above indicate that a vessel’s carrying amount may not be recoverable, we would then be required to estimate the undiscounted future cash flows expected to result from the use of the vessel and its eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of the vessel, we would be required to recognize an impairment loss.

Recertification Costs. Our vessels are required by regulation to be recertified after certain periods of time. These recertification costs are incurred while the vessel is in drydock where other routine repairs and maintenance are performed and, at times, major replacements and improvements are performed. We expense routine repairs and maintenance as they are incurred. Recertification costs can be accounted for in one of two ways: (1) defer and amortize or (2) expense as incurred. We defer and amortize recertification costs over the length of time that the recertification is expected to last, which is generally 30 or 60 months. Major replacements and improvements, which extend the vessel’s economic useful life or functional operating capability, are capitalized and depreciated over the vessel’s remaining economic useful life. Inherent in this process are estimates we make regarding the specific cost incurred and the period that the incurred cost will benefit.

Revenue Recognition. We charter our vessels to customers under time charters based on a daily rate of hire and recognize revenue as earned on a daily basis during the contract period of the specific vessel. We also contract our TTBs to customers under COAs, under which revenue is recognized based on the number of days incurred for the voyage as a percentage of total estimated days applied to total estimated revenues. Voyage related costs are expensed as incurred. Substantially all voyages under COAs are less than 10 days in length.

Allowance for Doubtful Accounts. Our customers are primarily major and independent, domestic and international, oil and gas and oil service companies. Our customers are granted credit on a short-term basis and related credit risks are considered minimal. We usually do not require collateral. We provide an estimate for uncollectible accounts based primarily on management’s judgment. Management uses historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts. Our historical losses have not been significant. However, because amounts due from individual customers can be significant, future adjustments to the

Index to Financial Statements

allowance can be material if one or more individual customer’s balances are deemed uncollectible.

Income Taxes. We follow SFAS No. 109, “Accounting for Income Taxes.” SFAS 109 requires the use of the liability method of computing deferred income taxes. Under this method, deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of our assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The assessment of the realization of deferred tax assets, particularly those related to tax net operating loss carryforwards, involves the use of management’s judgment to determine whether it is more likely than not that we will realize such tax benefits in the future. In addition, we adopted Financial Accounting Standards Board, or FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109”, or FIN 48, on January 1, 2007. As a result of the implementation of FIN 48, each reporting period, we assess and adjust for any significant changes to our liability for unrecognized income tax benefits. We account for any interest and penalties relating to uncertain tax positions in our current period income statement, as necessary.

Stock-Based Compensation Expense. Effective January 1, 2006, we adopted FAS No. 123 (revised 2004), “Share-Based Payment,” or FAS 123R, utilizing the modified prospective method. Prior to the adoption of FAS 123R, we accounted for stock option grants in accordance with APB Opinion No. 25, “Accounting for Stock Issued to Employees,” utilizing the intrinsic value method, and accordingly, recognized no compensation expense for stock option grants for periods prior to 2006. However, FAS 123R requires all share-based payments to employees and directors, including grants of stock options and restricted stock, to be recognized in the income statement based on their fair values. Compensation expense for the portion of awards for which the requisite service had not been rendered that were outstanding as of January 1, 2006 has been recognized as the service has been rendered on or after January 1, 2006. The compensation expense for that portion of awards was based on the grant-date fair value estimated in accordance with the original provisions of FAS 123, “Accounting for Stock-Based Compensation.” At December 31, 2007, approximately $0.2 million of unrecognized compensation expense related to nonvested stock option awards issued prior to January 1, 2006 is expected to be recognized over a weighted-average period of 0.2 years.

During the third quarter of 2007, the FASB proposed a new Staff Position (FSP) on APB 14-A, “Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement).” This proposal would specify that convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) are not addressed by paragraph 12 of APB Opinion No. 14, “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants.” In general, paragraph 12 of Opinion 14 precludes considering cash proceeds from the issuance of specified types of convertible debt instruments as attributable to the conversion feature. This FSP would nullify EITF No. 90-19, “Convertible Bonds with Issuer Option to Settle for Cash upon Conversion,” and EITF No. 03-7, “Accounting for the Settlement of the Equity-Settled Portion of a Convertible Debt Instrument That Permits or Requires the Conversion Spread to Be Settled in Stock (Instrument C of Issue No. 90-19).” The proposed FSP would also require that the

Index to Financial Statements

liability and equity components of a convertible debt instrument within the scope of the FSP be accounted for separately so that the accounting would reflect the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This FSP was issued on August 31, 2007 and had a 45-day comment period that ended on October 15, 2007. While the FASB is currently in re-deliberations regarding this proposed FSP, we are currently evaluating the potential impact of this proposed FSP on our prior and future operating results.

Index to Financial Statements

Revenues. Revenues for 2007 increased $64.4 million, or 23.5%, to $339.0 million from 2006 due to improved OSV market conditions in the GoM and additional vessels that were placed in service during 2007. Our average operating fleet was approximately 63 vessels for 2007 compared to 57 vessels for 2006.

Revenues from our OSV segment increased $62.0 million, or 37.2%, to $228.4 million for 2007 compared $166.4 million for 2006. The increase in revenue is due primarily to additional revenues generated by the vessels acquired in the Sea Mar Fleet acquisition that occurred in August 2007 and stronger dayrates for new generation OSVs that were in service during both 2007 and 2006. Additional revenues generated by the recently acquired 20 OSVs accounted for approximately $36.3 million of the OSV revenue increase. The remaining $25.7 million of the OSV revenue increase was attributable to vessels that were in service during 2006 and 2007. Our new generation OSV average dayrate was $21,505 in 2007 compared to $19,380 in 2006, an increase of $2,125 or 11.0%. Our new generation OSV utilization was 93.3% in 2007 compared to 90.3% in 2006. Our new generation OSV dayrates and utilization improved due primarily to continued strength in the GoM. Domestic revenues for our OSV segment increased $52.3 million during 2007 on the basis of strong market conditions in the GoM and the growth of our fleet. Foreign revenues for our OSV segment increased $9.7 million primarily due to the Sea Mar Fleet acquisition, which included four vessels that were operating in foreign markets.

Revenues from our TTB segment increased $2.4 million, or 2.3%, to $110.6 million for 2007 compared to 2006. The increase in TTB revenue was due primarily to the full-year contribution from a previously retired single-hulled tank barge, the Energy 8701, that was placed back into service in October 2006 and the partial-year contribution from two newbuild double-hulled tank barges, the Energy 6506 and Energy 6507, which were delivered in the latter half of 2007 under our second TTB newbuild program. Our tank barge average dayrates and utilization for 2007 were relatively flat compared to 2006.

Operating expenses. Operating expenses for 2007 grew 32.7% to $126.9 million compared to the same period in 2006 due primarily to the vessels added to our operating fleet through newbuild deliveries or acquisition and higher personnel costs. We expect cash operating expenses per vessel-day in 2008 for each segment to increase 5% to 10% over 2007.

Operating expenses for our OSV segment were $78.5 million, an increase of $23.3 million, or 42.3% for 2007 compared to 2006. The recently acquired Sea Mar vessels that were added to our operating fleet in August 2007 accounted for approximately $13.2 million of the operating expense increase over the year-ago period. Operating expenses were also impacted by higher personnel costs, including increased wages and FAS 123R stock-based compensation related to restricted stock unit awards granted to mariners. We also experienced higher maintenance and repair costs in 2007 compared to 2006.

Operating expenses for our TTB segment were $48.4 million, an increase of $7.9 million, or 19.7%, for 2007 compared to 2006. Operating expenses increased primarily due to wage increases for TTB mariners, higher FAS 123R stock-based compensation related to restricted stock unit awards granted to mariners, the increased cost of in-chartered third-party tugs and the full-year contribution of the Energy 8701, which was returned to service in late 2006. Vessels that were delivered in the latter half of 2007 under our second TTB newbuild program also contributed to the increase in TTB operating expense over the 2006 period. These factors were offset, in part, by lower insurance costs incurred during 2007.

Index to Financial Statements

Depreciation and Amortization. Depreciation and amortization expense was $3.1 million higher for 2007 compared to 2006, due to higher amortization of drydock costs for our vessels and incremental depreciation related to 20 vessels acquired in August 2007 and four vessels that were placed in service under our second TTB newbuild program during the second half of 2007. These increases were offset, in part, by the effect of our change in estimated salvage value for our vessels effective January 1, 2007. Depreciation and amortization expense is expected to increase further when the vessels under our current newbuild and conversion programs are placed in service and when these and any other recently acquired and newly constructed vessels undergo their initial 30 and 60 month recertifications.

General and Administrative Expense. General and administrative expenses of $32.9 million, or 9.7% of revenues, increased by $4.5 million during 2007 compared to 2006 due to higher personnel costs, FAS 123R stock-based compensation expense related to restricted stock unit awards granted to shore-based employees and increased costs for our variable incentive compensation plan. Our general and administrative expenses, inclusive of FAS123R expenses and the full-year effects of the Sea Mar Fleet acquisition, are expected to be approximately 9% to 10% of revenues in 2008.

Gain on Sale of Assets. During 2007, we recorded a $1.9 million gain in our OSV segment due to the sale of our only fast supply vessel. During 2006, we recorded a $1.9 million gain in our TTB segment due to the sale of the Energy 2202, a single-hulled tank barge, and the Ponce Service, a 3,900 horsepower tug, in May 2006 and October 2006, respectively.

Operating Income. Operating income increased by $25.5 million, or 21.2%, to $145.9 million during 2007 compared to 2006 for the reasons discussed above. Operating income as a percentage of revenues for our OSV segment was 49.9% for 2007 compared to 48.3% for 2006. The primary driver for this margin increase relates to higher effective dayrates. Operating income as a percentage of revenues for our TTB segment was 28.9% for 2007, compared to 37.0% for 2006. The primary driver for this margin decrease relates to flat dayrates compared to the prior year coupled with the increase in operating expenses discussed above.

Interest Expense. Interest expense decreased $2.0 million during 2007 compared to 2006. This decrease in interest expense was primarily due to a $5.7 million increase in capitalized interest during 2007 compared to 2006, offset by the November 2006 issuance of $250.0 million of 1.625% convertible senior notes. The increase in capitalized interest resulted from higher newbuild construction and conversion activity during 2007. See “Liquidity and Capital Resources” for further discussion.

Interest Income. Interest income increased $2.3 million during 2007 due primarily to higher interest rates earned on invested cash balances. Our average cash balance for 2007 was $323.9 million compared to $373.0 million for 2006. Our interest income is expected to trend downward in 2008 with lower average cash balances primarily resulting from cash outflows for the Sea Mar Fleet acquisition in August 2007, the acquisitions of the Superior Achiever and an additional shore-base in January 2008 and projected cash outflows committed to ongoing newbuild and conversion programs.

Income Tax Expense. Our effective tax rate was 36.2% and 36.3% for 2007 and 2006, respectively. Our income tax expense primarily consists of deferred taxes generated by accelerated depreciation for tax purposes. Our income tax rate is higher than the federal statutory rate, due primarily to expected state and foreign tax liabilities and items not deductible for federal income tax purposes. We expect our effective tax rate to be 36.5% in 2008.

Index to Financial Statements

Net Income. Net income increased by 25.2%, or $19.1 million, to $94.8 million primarily due to the increase in operating income and net interest income for the reasons discussed above, which was offset in part, by higher income tax expense.

Index to Financial Statements

Revenues. Revenues for 2006 increased 50.4%, or $92.0 million, to $274.6 million from 2005 due to continued favorable market conditions in each of our two business segments and the increase in our average fleet size due to acquisitions and new vessel construction. Our average operating fleet was approximately 57 vessels for 2006 compared to 53 vessels for 2005.

Revenues from our OSV segment were 41.7% higher for 2006 compared to 2005, due primarily to dayrate improvement attributed to continued strength in the GoM, the operation of a shore-based port facility leased in December 2005 and, to a lesser extent, a full-year contribution of one AHTS vessel acquired in early 2005 and placed in service in June 2005. Our OSV utilization rate was 90.3% in 2006 compared to 96.2% in 2005. Our OSV average dayrate was $19,380 in 2006 compared to $13,413 in 2005, an increase of $5,967 or 44.5%. Domestic revenues for our OSV segment were $141.3 million in 2006, an increase of $52.6 million or 59.2%, compared to $88.8 million in 2005. Foreign revenues for our OSV segment decreased by $3.6 million, or 12.6%, to $25.0 million for 2006 compared to $28.7 million in 2005 because we had an average of three fewer vessels operating internationally during 2006.

Revenues from our TTB segment were 66.0% higher in 2006 compared to 2005, due to market-driven higher utilization and dayrates and the full-year contribution of five newbuild double-hulled tank barges delivered on various dates throughout 2005. Our tank barge utilization increased to 92.7% for 2006 compared to 87.1% for 2005, due primarily to our continued shift in contract mix from COAs to time charters. Our tank barge average dayrate of $18,064 for 2006 increased $4,522, or 33.4%, from $13,542 for 2005. The increase in average dayrates was primarily attributed to our ability to capitalize on higher demand in the northeastern United States and diversified non-traditional TTB services, such as the support of deepwater well testing and other specialty applications for our upstream customers.

Operating expenses. Operating expenses for 2006 grew 42.9% to $95.6 million. The increase in operating expense during 2006 is primarily due to higher personnel costs, increases in our average fleet size, expansion of our shore-based operations and higher costs for in-chartering third party equipment.

Operating expenses for our OSV segment increased 53.5% for 2006 compared to 2005, primarily due to market-driven wage increases for OSV mariners, FAS 123R stock-based compensation related to restricted stock awards granted to mariners during 2006; the operation of an OSV shore-based port facility that was leased in December 2005; and an increase in customer-requested contract labor, the cost of which is offset by higher dayrates charged to such customers.

Operating expenses for our TTB segment increased 30.5% for 2006 compared to 2005, primarily as a result of market-driven wage increases for TTB mariners, FAS123R stock-based compensation related to restricted stock awards granted to mariners in 2006, the increased cost of three in-chartered third party tugs to fulfill time charter requirements, the full-year contribution of five new double-hulled tank barges delivered on various dates throughout 2005, the partial-year contribution of two higher horsepower, ocean-going tugs placed in service during the first half of 2006, and higher insurance costs. These increases were offset, in part, by lower fuel costs in 2006 due to a shift in contract mix from COAs to time charters. Under time charter arrangements, the charterer is typically responsible for fuel costs.

Index to Financial Statements

Depreciation and Amortization. Depreciation and amortization expense was $4.8 million higher for 2006 compared to 2005, due to a full year of depreciation for five new double-hulled tank barges that were placed in service throughout 2005, a shore-based port facility leased in December 2005, an AHTS vessel that was acquired in early 2005 and placed in service in June 2005 and, to a lesser extent, non-vessel capital expenditures that were completed during the second half of 2005. In addition, there were six OSVs that underwent their initial regulatory drydocking event during 2006, which resulted in amortization expense being recorded for these vessels for the first time.

General and Administrative Expense. General and administrative expenses of $28.4 million, or 10.3% of revenues, increased $8.1 million during 2006 compared to 2005. During 2006, we recorded $5.2 million of stock-based compensation expense as a result of adopting FAS 123R. No such expense was booked for periods prior to 2006. The remainder of the increase in general and administrative expense is the result of increased headcount to implement our growth strategy and increased amounts related to our cash incentive compensation plan awards, which vary commensurate with our financial results.

Gain on Sale of Assets. During 2006, we recorded a $1.9 million gain in our TTB segment due to the sale of the Energy 2202, a single-hulled tank barge, and the Ponce Service, a 3,900 horsepower tug, in May 2006 and October 2006, respectively. During 2005, we recorded a $1.9 million gain in our TTB segment due to the sales of the Energy 9801 and the Energy 9501, two retired single-hulled tank barges, and the Yabucoa Service and the North Service, two older, lower horsepower tugs.

Operating Income. Our operating income increased by $50.4 million, or 72.1%, during 2006 for the reasons described above. Operating income as a percentage of revenues for our OSV segment was 48.3% for 2006 compared to 48.5% for 2005. Operating income as a percentage of revenues for our TTB segment was 37.0% for 2006 compared to 19.9% for 2005. The 2006 TTB margin increase was primarily related to the shift in our TTB contract mix from COAs to time charters and the ability to deploy our TTB vessels in non-traditional TTB services, such as the support of deepwater well testing and other specialty applications for our upstream customers.

Interest Expense. Interest expense increased $5.1 million in 2006 compared to 2005, primarily as a result of the October 2005 issuance of an additional $75.0 million in principal amount outstanding under our 6.125% senior notes, lower capitalized interest and, to a lesser extent, the November 2006 issuance of $250.0 million of 1.625% convertible senior notes. Capitalized interest decreased $1.4 million during 2006 compared to 2005, due to a lower average construction work-in-progress balance and, to a lesser degree, a lower blended-average interest rate. See “Liquidity and Capital Resources” for further discussion.

Interest Income. Interest income increased $12.9 million in 2006 resulting from increased interest rates on higher invested cash balances primarily due to the October 2005 debt and equity offerings along with approximately $156.6 million of net proceeds from the November 2006 convertible senior notes offering. Our average cash balance for 2006 was $373.0 million compared to $163.0 million in 2005. Our cash balance as of December 31, 2006 was $474.3 million. Our average interest rate earned on invested cash during 2006 was approximately 5.0% compared to approximately 3.9% in 2005, primarily due to six sequential 25-basis point changes in the Federal Funds rate in 2006.

Index to Financial Statements

Income Tax Expense. Our effective tax rate was 36.3% and 36.5% for 2006 and 2005, respectively. Our income tax expense primarily consists of deferred taxes due to our federal tax net operating loss carryforwards. Our income tax rate is higher than the federal statutory rate, due primarily to expected state and foreign tax liabilities and items not deductible for federal income tax purposes. We recorded deferred taxes due to our federal tax net operating loss carryforwards of approximately $37.3 million as of December 31, 2006 primarily generated by accelerated depreciation for tax purposes. These loss carryforwards are available through 2025 to offset future taxable income.

Net Income. Net income increased by $38.3 million, or 102.2%, to $75.7 million primarily due to the growth in operating income and net interest income for the reasons discussed above, which was offset in part, by higher income tax expense in 2006.

Liquidity and Capital Resources

Our capital requirements have historically been financed with cash flows from operations, proceeds from issuances of our debt and common equity securities, borrowings under our credit facilities, and cash received from the sale of assets. We require capital to fund on-going operations, vessel construction, retrofit or conversion, acquisitions, vessel recertifications, discretionary capital expenditures and debt service. The nature of our capital requirements and the types of our financing sources are not expected to change significantly during 2008.

We have from time to time made, and will make additional, short-term draws on our revolving credit facility to satisfy scheduled capital expenditure requirements or for other corporate purposes. Any liquidity in excess of our planned capital expenditures will be utilized to repay debt or finance the implementation of our growth strategy, which includes expanding our fleet through the construction of new vessels, conversion or retrofit of existing vessels or acquisition of additional vessels, including, but not limited to, OSVs, MPSVs, AHTS vessels, ocean-going tugs, tank barges, tankers and other specialty vessels, as needed to take advantage of the market demand for such vessels. In January 2008, we increased the borrowing base of our revolving credit facility from $100.0 million to $250.0 million by exercising the accordion feature under such facility. See further discussion in Commitments and Capital Obligations.

We believe that our current working capital, projected cash flows from operations and available capacity under our revolving credit facility, will be sufficient to meet our cash requirements for the foreseeable future. These sources of cash were available to fund, and will continue to fund our recent acquisitions and previously announced vessel newbuild and conversion programs, including the expansion of such programs announced since their commencement. Although we expect to continue generating positive working capital through our operations, events beyond our control, such as declines in expenditures for exploration, development and production activity, mild winter conditions or a reduction in domestic consumption of refined petroleum products and other reasons discussed under “Forward Looking Statements” below, may affect our financial condition or results of operations. Depending on the market demand for such vessels and other growth opportunities that may arise, we may require additional debt or equity financing.

Index to Financial Statements

As of December 31, 2007, we had total cash and cash equivalents of $173.6 million. The January 2008 acquisition costs for the Superior Achiever and leased property adjacent to HOS Port have been, and the remaining construction costs related to our MPSV program, our fourth OSV newbuild program and our second TTB newbuild program will be, funded, in part, with cash on hand, including a portion of the net proceeds from our prior debt and equity securities offerings, projected cash flows from operations and borrowings available under our recently expanded revolving credit facility, which is currently undrawn.

Cash Flows

Operating Activities. We rely primarily on cash flows from operations to provide working capital for current and future operations. Cash flows from operating activities were $135.4 million in 2007, $131.8 million in 2006 and $75.8 million in 2005. The increase in operating cash flows from 2006 to 2007 was primarily the result of an increase in effective dayrates in our OSV segment and the growth of our fleet. The increase in cash flows from operations for 2007 reflects a full-year contribution from a previously retired tank barge that was returned to service during the fourth quarter of 2006, the partial-year contribution from two additional double-hulled newbuild tank barges that were placed in service during the latter half of 2007 and the partial-year contribution from OSVs that were acquired in August 2007. The increases were offset, in part, by higher deferred drydocking costs. These increases in operating cash flows from 2005 to 2006 was the result of substantially improved market conditions in both of our business segments and the growth of our fleet as a result of acquisitions and new construction. In addition, our cash flows from operations for 2006 reflect a full period of revenue contribution from two additional AHTS vessels and five new double-hulled tank barges that were placed in service during 2005 offset, in part, by higher deferred drydocking costs. Our cash flows from operations should continue to be positively impacted in 2008 by a full-year contribution of revenue from the recently acquired Sea Mar Fleet and vessels delivered during 2007 under our second TTB newbuild program and a partial-year of revenue contribution from vessels to be delivered on various dates throughout 2008 under our MPSV program, our fourth OSV newbuild program, and our second TTB newbuild program.

Investing Activities. Net cash used in investing activities was $438.9 million in 2007, $87.1 million in 2006 and $120.6 million in 2005. Cash utilized in 2007 primarily consisted of the Sea Mar Fleet acquisition from Nabors in August 2007 and construction costs incurred for our MPSV program, our fourth OSV newbuild program, and our second TTB newbuild program. These investing activities were partially offset by approximately $5.9 million in net cash inflows from the April 2007 sale of the HOS Hotshot, our only fast supply vessel. Cash invested for 2006 consisted of construction costs incurred for our first and second TTB newbuild programs, our MPSV conversion program, our fourth OSV newbuild program and improvements made to our shore-based port facility. The cash utilized for investing activities during 2006 was partially offset by approximately $4.1 million of cash inflows from the sale of a single-hulled tank barge and an ocean-going tug. Cash invested for 2005 primarily consisted of construction costs incurred for our first TTB newbuild program and the acquisitions of two foreign-flagged AHTS vessels and one coastwise tanker, the latter of which is being retrofitted under our MPSV conversion program. The cash utilized for investing activities during 2005 was partially offset by approximately $4.3 million of net cash inflows

Index to Financial Statements

from the sales of two retired single-hulled tank barges and two ocean-going tugs. Investing activities for 2008 are anticipated to include costs related to our MPSV program, our fourth OSV newbuild program, our second TTB newbuild program, and other capital expenditures, including discretionary vessel modifications and corporate projects.

Financing Activities. Net cash provided by financing activities was $2.7 million in 2007, $157.8 million in 2006 and $262.2 million in 2005. Net cash provided by financing activities for 2007 resulted from the net proceeds from common stock issued under employee benefit programs. Net cash provided by financing activities for 2006 primarily resulted from net cash proceeds generated from our November 2006 convertible senior note offering and the accompanying convertible note hedge, warrant sale, and stock repurchase transactions. Net cash provided by financing activities for 2005 primarily resulted from our October 2005 public offering of 6.1 million shares of our common stock resulting in net proceeds of approximately $205.4 million. We also received approximately $73.1 million in net proceeds in connection with the concurrent private placement of an additional $75.0 million in aggregate principal amount of our 6.125% senior notes due 2014, or additional notes, under our indenture dated as of November 23, 2004. The additional notes were priced at 99.25% of principal amount to yield 6.41% and have substantially the same terms as the existing 6.125% senior notes issued in November 2004. Net cash provided by financing activities during 2005 was also offset by the redemption of the $15.5 million non-tendered 10.625% senior notes in January 2005. Financing activities for 2008 are expected to include proceeds from borrowings under our recently expanded revolving credit facility.

Debt

As of December 31, 2007, we had outstanding debt of $299.5 million, net of original issue discount, under our 6.125% senior unsecured notes, or senior notes, that were issued on November 23, 2004. The effective interest rate on the senior notes is 6.38%. Semi-annual cash interest payments of $9.2 million are due and payable each June 1 and December 1. The senior notes do not require any payments of principal prior to their stated maturity of December 1, 2014, but pursuant to the 2004 indenture under which the senior notes were issued, we would be required to make offers to purchase such senior notes upon the occurrence of specified events, such as certain asset sales or a change in control.

On October 5, 2005, we closed an underwritten public offering of 6.1 million shares of our common stock under an effective Form S-3 universal shelf for total gross proceeds to us of $215.6 million before underwriting discounts, commissions and offering expenses. On October 5, 2005, we used a portion of the net proceeds from the public offering of common stock and concurrent private placement of $75.0 million of additional 6.125% senior notes to pay down our then-outstanding $21.0 million balance under our prior revolving credit facility due February 2009 to a zero balance.

On September 27, 2006, we entered into a new senior secured revolving credit facility with a borrowing base, at that time, of $100.0 million and an accordion feature that allowed for an increase in the size of the facility to an aggregate of $250.0 million in certain circumstances. This new senior secured revolving credit facility replaced our prior revolving credit facility. On February 20, 2008, we exercised the accordion feature of such revolving credit facility and increased the borrowing base to $250.0 million. We now have a total of four ocean-going tugs and 24 new generation OSVs, with an aggregate market value of at least $500 million, pledged as collateral under this expanded facility. The facility has a maturity date of September 27, 2011. As of December 31, 2007, based on our then-borrowing base of $100.0 million, we had $99.6 million of credit immediately available under such revolving credit facility as we had approximately $0.4 million pledged as letters of credit. As of December 31, 2007, no amounts were drawn against the letters of credit.

On November 13, 2006, we completed a private offering of $250.0 million of our 1.625% convertible senior unsecured notes due 2026, or the convertible notes, to “qualified institutional buyers” pursuant to Rule 144A under the Securities Act. During the first quarter of 2007, we registered the resale of the convertible notes by the holders thereof. The convertible notes will initially bear interest at a fixed rate of 1.625% per year, declining to 1.375% beginning on November 15, 2013, payable semi-annually on May 15 and November 15 of each year, with the first interest payment payable on May 15, 2007. The convertible notes are convertible into shares of our common stock at an initial conversion price of approximately $48.48 per share, upon the occurrence of certain events, including the closing price of our common stock exceeding 137.5% of the conversion price per share for 20 of the last 30 trading days of any calendar quarter. If, upon the occurrence of certain events, the holders of the convertible notes exercise the conversion provisions of the convertible notes, we may need to remit the principal balance of the convertible notes to them in cash as discussed below. As such, we would classify the entire amount of the convertible notes outstanding as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the convertible notes will occur every calendar quarter. Upon conversion, a holder will receive, in lieu of shares of common stock, an amount of cash equal

Index to Financial Statements

to the lesser of (i) the principal amount of the convertible note, or (ii) the conversion value, determined in the manner set forth in the indenture governing the convertible notes, of a number of shares equal to the conversion rate. If the conversion value exceeds the principal amount of the convertible note on the conversion date, we will also deliver, at our election, cash or shares of our common stock or a combination of cash and shares of our common stock with respect to the conversion value upon conversion. If conversion occurs in connection with a change of control, we may be required to deliver additional shares of our common stock by increasing the conversion rate with respect to such convertible notes.

We used a portion of the $243.8 million in net proceeds of the convertible notes offering, along with a portion of the $51.9 million in proceeds from the sale of warrants, to fund the $75.8 million cost of convertible note hedge transactions and the $63.3 million cost to repurchase approximately 1.8 million shares of our common stock contemporaneously with the closing of the convertible notes offering on November 13, 2006. The remaining net proceeds of the convertible notes offering and the warrant transactions of approximately $156.6 million was available for general corporate purposes, including possible acquisitions and additional new vessel construction.

Holders of the convertible notes may convert their notes prior to the close of business on the business day before the stated maturity date based on the applicable conversion rate only under the following circumstances:

•

during any calendar quarter (and only during such calendar quarter), if the closing price of our shares of common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is more than 135% of the conversion price per share, which is $1,000 divided by the then applicable conversion rate;

•

prior to November 15, 2013, during the five business day period after a 10 consecutive trading day period in which the trading price per $1,000 principal amount of convertible notes for each day of that period was less than 95% of the product of the closing price for our shares of common stock for each day of that period and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the convertible notes;

•

if the convertible notes have been called for redemption, or

•

upon the occurrence of specified corporate transactions, as defined by the convertible note agreement.

The initial conversion rate is 20.6260 shares of common stock per $1,000 principal amount of the convertible notes. This is equivalent to an initial conversion price of approximately $48.48 per share of common stock.

In addition, holders of the convertible notes have the right to require us to purchase all or a portion of their notes on each of November 15, 2013, November 15, 2016 and November 15, 2021. Among other conditions, the holders of the convertible notes will be required to deliver a written purchase notice to a paying agent with such notice being delivered beginning any time from the opening of business on the date that is 20 business days prior to the relevant purchase date. The purchase price payable will be equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest, including any additional amounts, to such purchase date.

Index to Financial Statements

Prior to November 15, 2011, the convertible notes will not be redeemable. However, on or after November 15, 2011, but prior to November 15, 2013, we may redeem for cash all or part of the convertible notes provided that the last reported sale price of shares of our common stock is greater than or equal to 135% of the conversion price then in effect for at least 20 trading days within a period of 30 consecutive trading days and proper notice, as described in the convertible note agreement, has been given to the trustee, holder of the convertible notes and the paying agent. On or after November 15, 2013, we may redeem for cash all or part of the convertible notes at any time provided notice is given to the trustee, holder of the convertible notes and the paying agent.

In early 2007, the SEC declared effective our shelf registration statement with respect to the resale of the convertible notes and the shares of our common stock issuable upon conversion of the convertible notes. We have agreed to keep such shelf registration statement effective until the earlier of (i) the sale pursuant to the shelf registration statement of all of the convertible notes and/or shares of common stock issuable upon conversion of the convertible notes, and (ii) the date when the holders, other than the holders that are our affiliates, of the convertible notes and the common stock issuable upon conversion of the convertible notes are able to sell all such securities immediately without restriction pursuant to the volume limit provisions of Rule 144(k) under the Securities Act or any successor rule thereto or otherwise. We will be required to pay additional interest, subject to some limitations, to the holders of the convertible notes if we fail to comply with our obligations to keep such shelf registration statement effective for the specified time period.

For additional information with respect to our new revolving credit facility, our 6.125% senior notes and our 1.625% convertible senior notes, including the related convertible note hedge and warrant transactions, please refer to note 6 of our consolidated financial statements included herein.

Capital Expenditures and Related Commitments

The following table sets forth the amounts incurred, before construction period interest, during the year ended December 31, 2007 and since each program’s inception, respectively, as well as the estimated total project costs for each of our current expansion programs (in millions):


	For the Year Ended December 31, 2007		Incurred Since Inception		Estimated Program Totals⁽¹⁾		Projected Delivery Dates⁽¹⁾
Growth Capital Expenditures:
MPSV program⁽²⁾	$	106.7	$	145.9	$	450.0	3Q2008-4Q2009
OSV newbuild program #4⁽³⁾		71.5		93.6		393.0	2Q2008-4Q2010
TTB newbuild program #2⁽⁴⁾		49.6		69.0		77.0	3Q2007-2Q2008
Sea Mar Fleet acquisition⁽⁵⁾		186.0		186.0		186.0	3Q2007

Total:	$	413.8	$	494.5	$	1,106.0

(1)

Estimated Program Totals and Projected Delivery Dates (other than for the Sea Mar Fleet acquisition) are based on internal estimates and are subject to change due to delays and possible cost overruns inherent in any large construction project, including shortages of equipment, lack of shipyard availability, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, inability to obtain necessary certifications and approvals and shortages of materials, component equipment or skilled labor. All of the above historical and budgeted capital expenditure project amounts for our newbuild and conversion programs represent estimated cash outlays and do not include any allocation of capitalized construction period interest. Projected delivery dates correspond to pending vessels that are currently contracted with shipyards for construction, retrofit or conversion.

Our MPSV program now consists of two coastwise sulfur tankers that are being converted into U.S.-flagged, proprietary 370 class DP-2 new generation MPSVs at a domestic shipyard, and two T-22 class DP-3 new generation MPSVs that are being constructed in a foreign shipyard. The first converted DP-2 MPSV is expected to be delivered from the shipyard in the third quarter of 2008, while the second converted DP-2 MPSV is expected to be delivered in late 2008 or early 2009. The first newbuild DP-3 MPSV is expected to be delivered from the foreign

shipyard during the fourth quarter of 2008, while the second newbuild DP-3 MPSV is expected to be delivered during the fourth quarter of 2009. Based on internal estimates, the aggregate cost of the MPSV program, prior to the allocation of construction period interest, is expected to be approximately $450.0 million, including the recent acquisition cost of the Superior Achiever,

(3)

Our fourth OSV newbuild program now consists of vessel construction contracts with three domestic shipyards to build six proprietary 240 ED class OSVs, nine proprietary 250 EDF class OSVs and one 285 class DP-2 new generation OSV, respectively. These 16 new generation OSVs are expected to be placed in service on various dates from the second quarter of 2008 through the end of 2010. Inclusive of the two recently announced vessel additions, the aggregate cost of our fourth OSV newbuild program is now expected to be approximately $393.0 million.

(4)

Our second TTB newbuild program consists of vessel construction contracts with three domestic shipyards to build three 60,000-barrel double-hulled tank barges and retrofit four 3,000 horsepower ocean-going tugs that were purchased in July 2006. We delivered three newbuild double-hulled tank barges, the Energy 6506, Energy 6507 and Energy 6508, and three retrofitted ocean-going tugs, the Michigan Service, Huron Service, and Superior Service, on various dates throughout the latter half of 2007 and early 2008. We expect to place in service one retrofitted tug, the Erie Service, during the second quarter of 2008. We estimate the total cost of our second TTB newbuild program, before construction period interest, to be approximately $77.0 million.

(5)	In August 2007, we completed the acquisition of the 20-vessel Sea Mar Fleet from Nabors for cash consideration of $186.0 million.

The following table summarizes the costs incurred for the purposes set forth below for the years ended December 31, 2007, 2006 and 2005, as well as a forecast for 2008 (in millions):


	Year Ended December 31,
	2008		2007		2006		2005
	Forecast		Actual		Actual		Actual
Maintenance Capital Expenditures:
Deferred drydocking charges⁽¹⁾	$	19.3	$	19.8	$	12.9	$	6.8
Other vessel capital improvements⁽²⁾		24.4		18.0		8.4		4.0
Non-vessel capital expenditures⁽³⁾		24.6		4.9		5.1		2.6

Total:	$	68.3	$	42.7	$	26.4	$	13.4

(1)	Deferred drydocking charges for 2008 include the projected recertification costs for nine OSVs, four tugs, and ten tank barges.

(2)	Other vessel capital improvements include costs for discretionary vessel enhancements, which are typically incurred during a planned drydocking event to meet customer specifications.

(3)	Non-vessel capital expenditures for 2008 are comprised of the recent acquisition of and planned improvements to the shore-base adjacent to HOS Port, with the balance of such costs primarily related to information technology initiatives, transportation assets and corporate projects.

Inflation

To date, general inflationary trends have not had a material effect on our operating revenues or expenses.

Item 7A—Quantitative and Qualitative Disclosures About Market Risk

We have not entered into any derivative financial instrument transactions to manage or reduce market risk or for speculative purposes, other than the convertible note hedge and warrant transactions entered into concurrently with our convertible note offering in November 2006. Such transactions were entered into to mitigate the potential dilutive effect of the conversion feature of the convertible notes on our common stock.

Changes in interest rates may result in changes in the fair market value of our financial instruments, interest income and interest expense. Our financial instruments that are exposed to interest rate risk are cash equivalents and long-term borrowings. Due to the short duration and conservative nature of our cash equivalent investment portfolio, we do not expect any material loss with respect to our investments. The book value for cash equivalents is considered to be representative of its fair value.

We are subject to interest rate risk on our long-term fixed interest rate 6.125% senior notes and 1.625% convertible senior notes. In general, the fair market value of debt with a fixed interest rate will increase as interest rates fall. Conversely, the fair market value of debt will decrease as interest rates rise. The currently outstanding 6.125% senior notes accrue interest at the rate of 6.125% per annum and mature on December 1, 2014 and the effective interest rate on such notes is 6.39%. Our outstanding 1.625% convertible senior notes accrue interest at the rate of 1.625%, which will decline to 1.375% beginning on November 15, 2013, and mature on November 15, 2026 and the effective interest rate on such notes is 2.04%. Our revolving credit facility has a variable interest rate and, therefore, is not subject to interest rate risk.

Our operations are primarily conducted between U.S. ports, including along the coast of Puerto Rico, and historically we have not been exposed to significant foreign currency fluctuation. However, as we expand our operations in international markets, we may become exposed to certain risks typically associated with foreign currency fluctuation. We currently have time charters for four of our OSVs for service offshore Trinidad. Although such contracts are denominated and will be paid in U.S. Dollars, value added tax, or VAT, payments are paid in Trinidad & Tobago dollars which creates an exchange risk related to currency fluctuations. In addition, we are currently operating under fixed time charters with five OSVs offshore Mexico and two OSVs offshore Qatar. Although we are paid in U.S. Dollars, there is an exchange risk to foreign currency fluctuations related to the payment terms of such time charters. We also have two shipyard contracts denominated in Euros for the construction of two MPSVs in the Netherlands, which creates an exchange risk to foreign currency fluctuations related to the payment terms of such shipyard draw payments. To date, we have not hedged against any foreign currency rate fluctuations associated with foreign currency VAT payments or other foreign currency denominated transactions arising in the normal course of business. We continually monitor the currency exchange risks associated with conducting international operations. To date, gains or losses associated with such fluctuations have not been material.

Item 9A—Controls and Procedures

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13(a)-15(f) or Rule15d-15(f) under the Exchange Act. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes maintaining records that, in reasonable detail, accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with U.S. generally accepted accounting principles; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with authorizations of the Company’s management and board of directors; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies of procedures may deteriorate.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2007, utilizing the criteria set forth in the report entitled Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon such assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2007.

Ernst & Young LLP, an independent registered public accounting firm, who audited our consolidated financial statements included in this Form 10-K, has issued an attestation report on our internal control over financial reporting which is included herein.

There were no changes in our internal controls over financial reporting that occurred during the quarter ended December 31, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Hornbeck Offshore Services, Inc.

We have audited Hornbeck Offshore Services, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Hornbeck Offshore Services, Inc’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Hornbeck Offshore Services, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Hornbeck

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Hornbeck Offshore Service, Inc. and subsidiaries at December 31, 2007 and 2006, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2007 the Company adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109”, effective January 1, 2007 the Company changed its estimated salvage values for marine equipment, and effective January 1, 2006 the Company adopted the provisions of FASB No. 123 (revised 2004) regarding share-based payments.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board, Hornbeck Offshore Service, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2008 expressed an unqualified opinion thereon.

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

Nature of Operations

Hornbeck Offshore Services, Inc., or the Company, was incorporated in the state of Delaware in 1997. The Company, through its subsidiaries, operates offshore supply vessels, or OSVs, to provide logistics support and specialty services to the offshore oil and gas exploration and production industry, primarily in the U.S. Gulf of Mexico, or GoM, and select international markets. The Company, through its subsidiaries, also operates ocean-going tugs and tank barges that provide transportation of petroleum products, primarily in the northeastern United States, GoM and Puerto Rico. All significant intercompany accounts and transactions have been eliminated.

The Company owns a 49% interest in Hornbeck Offshore Trinidad & Tobago Limited, or HOTT-Ltd. HOTT-Ltd is a vessel crewing and management services company established to support the Company’s Trinidad & Tobago-based operations. The 49% interest owned by the Company is being recorded using the equity method. The Company’s equity in income from investments is not material.

2. Summary of Significant Accounting Policies

Revenue Recognition

The Company charters its OSVs and certain of its tank barges to clients under time charters based on a daily rate of hire and recognizes revenue as earned on a daily basis during the contract period of the specific vessel.

The Company also contracts certain of its tank barges to clients under contracts of affreightment, or COAs, under which revenue is recognized based on the number of days incurred for the voyage as a percentage of total estimated days applied to total estimated revenues. Voyage related costs are expensed as incurred. Substantially all voyages under these contracts are less than 10 days in length.

Deferred revenue represents payments received from customers in advance of vessels commencing time charters.

Cash and Cash Equivalents

Cash and cash equivalents consist of all highly liquid investments in money market funds, deposits and investments available for current use with an initial maturity of three months or less.

Accounts Receivable

Accounts receivable consists of trade receivables net of reserves, amounts to be rebilled to customers and interest receivables.

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation and amortization of equipment and leasehold improvements are computed using the straight-line method based on the estimated useful lives of the related assets. Major modifications and improvements, which extend the useful life or capabilities of the vessel, are capitalized and amortized over the remaining useful life of the vessel. Gains and losses from retirements or other dispositions are recognized as incurred. Effective January 1, 2007, the Company modified its assumptions regarding estimated salvage values for its marine equipment. Salvage values for marine equipment are estimated to range between 5% and 25% of the originally recorded cost, depending on vessel type. For the year ended December 31, 2007, this change in estimated salvage values resulted in an increase in operating income, net income and diluted earnings per share of approximately $6.2 million, $4.0 million and $0.15, respectively. The Company’s depreciation expense for vessels that were in service as of January 1, 2007, as well as for vessels placed in service after that date, are expected to be lower for the remaining estimated useful life of such assets based on the change in the Company’s estimated salvage values.

The estimated useful lives by classification are as follows:


Tugs		14-25 years
Tank barges		3-25 years
Offshore supply vessels		25 years
Non-vessel related property, plant and equipment		3-28 years

All of the Company’s single-hulled tank barges have estimated useful lives based on their classification under the Oil Pollution Act of 1990. The Company’s double-hulled tank barges have an estimated useful life of 25 years.

Deferred Charges

The Company’s vessels are required by regulation to be recertified after certain periods of time. The Company defers the drydocking expenditures incurred due to regulatory marine inspections and amortizes the costs on a straight-line basis over the period to be benefited from such improvements (generally 30 or 60 months). Financing charges are amortized over the term of the related debt.

Deferred charges also include prepaid lease expenses related to the Company’s shore-based port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

F-8

Index to Financial Statements

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Deferred tax assets and liabilities are measured using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The provision for income taxes includes provisions for federal, state and foreign income taxes.

Use of Estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Concentration of Credit Risk

Customers are primarily major and independent, domestic and international, oil and oil service companies. The Company’s customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company usually does not require collateral. The Company provides an estimate for uncollectible accounts based primarily on management’s judgment using historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts.

The following table represents the allowance for doubtful accounts (in thousands):


	December 31,
	2007		2006		2005
Balance, beginning of year	$	745	$	495	$	407
Changes to provision		303		250		88

Balance, end of year	$	1,048	$	745	$	495

Goodwill

Goodwill reflects the excess of cost over the estimated fair value of the net assets acquired. Fair value is determined based on discounted cash flow or appraised values, as appropriate. The Company has performed goodwill impairment reviews by reporting unit based on a fair value concept as required by Statement of Financial Accounting Standards (SFAS) No. 142, “Goodwill and Other Intangible Assets”, using a multiple of earnings before interest, taxes, depreciation and amortization (EBITDA) and earnings per share. Such fair value calculations have not resulted in the impairment of goodwill.

Stock-Based Compensation

Effective January 1, 2006, the Company adopted SFAS No. 123 (revised 2004), “Share-Based Payment,” or FAS 123R, using the modified prospective method. Prior to the adoption of FAS 123R, the Company accounted for stock option grants in accordance with APB 25, using the intrinsic value method, and accordingly, no compensation expense was recorded for

F-9

Index to Financial Statements

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

stock option grants for periods prior to 2006. Under the modified prospective method, FAS 123R applies to new awards and to awards that were outstanding on January 1, 2006 or were repurchased or cancelled after the FAS 123R-required effective date. Additionally, compensation expense for the portion of awards for which the required service has not been rendered that are outstanding as of January 1, 2006 shall be recognized as the service is rendered on or after January 1, 2006. The compensation expense for that portion of awards shall be based on the grant-date fair value estimated in accordance with the original provisions of FAS 123, and compensation expense for all share-based payments granted subsequent to January 1, 2006, shall be based on the grant-date fair value estimated in accordance with the provisions of FAS 123R. Prior periods were not restated to reflect the impact of adopting the new standard.

Impairment of Long-Lived Assets

When events or circumstances indicate that the carrying amount of long-lived assets to be held and used or intangible assets might not be recoverable, the expected future undiscounted cash flows from the assets are estimated and compared with the carrying amount of the assets. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Fair value is determined based on discounted cash flow or appraised values, as appropriate. The Company did not record any impairment losses related to its long-lived assets during 2007, 2006 or 2005.

Reclassifications

Certain prior year amounts in the financial statements have been reclassified to conform to the current year presentation. These reclassifications had no impact on the Company’s results of operations.

Recent Accounting Pronouncements

In September 2006, the FASB issued FASB Statement No. 157, “Fair Value Measurements”, or SFAS 157, which defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about fair value measurements. This statement is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. Management currently does not expect SFAS No. 157 to have a material effect on the results of operations or financial position of the Company.

On January 1, 2007 the Company adopted Financial Accounting Standards Board, or FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109”, or FIN 48. As a result of the implementation of FIN 48, the Company did not record any significant changes to its liability for unrecognized income tax benefits. As of December 31, 2007, the Company had approximately $0.4 million of unrecognized income tax benefits, of which approximately $0.3 million would affect the effective tax rate if recognized. The Company accounts for interest and penalties relating to

uncertain tax positions in the current period income statement, as necessary. The 2003 through 2007 tax years remain subject to examination by various federal, state and foreign tax jurisdictions.

In December 2007, the FASB issued FASB Statement No. 141(R), “Business Combinations”, or SFAS 141(R). SFAS No. 141(R) applies to any transaction or other event that meets the definition of a business combination. Where applicable, SFAS No. 141(R) establishes principles and requirements for how the acquirer recognizes and measures identifiable assets acquired, liabilities assumed, noncontrolling interest in the acquiree and goodwill or gain from a bargain purchase. In addition, SFAS 141(R) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. This statement is to be applied prospectively for fiscal years beginning after December 15, 2008. The Company is in the process of evaluating the impact of SFAS No. 141(R) on its Consolidated Financial Statements.

3. Earnings Per Share

Basic earnings per common share was calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share was calculated by dividing net income by the weighted average number of common shares outstanding during the year plus the effect of dilutive stock options. Weighted average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period. The table below reconciles the company’s earnings per share (in thousands, except for per share data):


	Year Ended December 31,
	2007		2006		2005
Net income	$	94,791	$	75,715	$	37,443

Weighted average number of shares of common stock outstanding		25,662		26,966		22,369
Add: Net effect of dilutive stock options⁽¹⁾⁽²⁾		805		495		468

Adjusted weighted average number of shares of common stock outstanding⁽³⁾		26,467		27,461		22,837

Earnings per common share:
Basic	$	3.69	$	2.81	$	1.67

Diluted	$	3.58	$	2.76	$	1.64

(1)

As of December 31, 2007, 2006 and 2005, stock options representing rights to acquire 146, 323, and 42 shares, respectively, of common stock were excluded from the calculation of diluted earnings per share because the effect was antidilutive. Stock options are anti-dilutive when the exercise price of the options is greater than the average market price of the common stock for the period or when the results from operations are a net loss.

(2)	For the year ended December 31, 2007 and 2006, the 1.625% convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of the notes. See note 6 for further information.

(3)	Dilutive restricted stock is expected to fluctuate from quarter to quarter depending the Company’s performance compared to a predetermined set of performance criteria. See note 4 for further information regarding certain of the Company’s restricted stock awards.

4. Defined Contribution Plan

The Company offers a 401(k) plan to all full-time employees. Employees must be at least twenty-one years of age and have completed three months of service to be eligible for participation. Participants may elect to defer up to 60% of their compensation, subject to

certain statutorily established limits. The Company may elect to make annual matching and/or profit sharing contributions to the 401(k) plan. During the years ended December 31, 2007, 2006 and 2005, the Company made contributions to the 401(k) plan of approximately $1.5 million, $0.9 million, and $0.6 million, respectively.

6. Long-Term Debt

Senior Notes

On July 24, 2001, the Company issued $175.0 million in aggregate principal amount of 10.625% senior notes, or old senior notes. The old senior notes were due to mature on August 1, 2008 and required semi-annual interest payments at an annual rate of 10.625% on February 1 and August 1 of each year until maturity. The effective interest rate on the old senior notes was 11.18%. No principal payments were due until maturity. On November 3, 2004, the Company commenced a cash tender offer for all of the old senior notes. Old senior notes totaling approximately $159.5 million, or 91% of the notes outstanding, were validly tendered during the designated tender period and repurchased during 2004. The remaining $15.5 million of old senior notes were redeemed on January 14, 2005. A loss on early extinguishment of debt for the old senior notes of approximately $22.4 million and $1.7 million was recorded during the fourth quarter of 2004 and the first quarter of 2005, respectively. These losses include the tender offer costs, the write-off of unamortized financing costs and original issue discount, and a bond redemption premium.

On November 23, 2004, the Company issued in a private placement $225.0 million in aggregate principal amount of 6.125% senior notes, or new senior notes, governed by an indenture, or the 2004 indenture. The net proceeds to the Company from the private placement were approximately $219.0 million, net of transaction costs. The Company used $198.0 million of the proceeds to repurchase or redeem all of the old senior notes. The $198.0 million comprised the total consideration paid for the old senior notes, including

F-12

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

related tender offer costs, consent fees, and bond redemption premium required to be paid to holders of the old senior notes. The residual proceeds were used for the acquisition, construction and retrofit of vessels. The effective interest rate on the new senior notes is 6.38%.

On October 4, 2005, the Company issued in a private placement an additional $75.0 million in aggregate principal amount of 6.125% senior notes, or additional notes, governed by the 2004 indenture. The additional notes were priced at 99.25% of principal amount to yield 6.41%. The net proceeds to the Company from this private placement were approximately $73.1 million, net of transaction costs. The Company used the proceeds from the sale of the additional notes, as well as the proceeds from its concurrent public offering of common stock, to partially fund the construction of new OSVs, ocean-going tugs and ocean-going, double-hulled tank barges and the retrofit or conversion of certain existing vessels, including MPSVs. In addition, the combined proceeds may be used in connection with possible future acquisitions and additional new vessel construction programs, as well as for general corporate purposes. Pending these uses, the Company repaid debt under its revolving credit facility, which may be reborrowed.

Pursuant to a registered exchange offer, the new senior notes and additional notes issued in November 2004 and October 2005 that were initially sold pursuant to private placements were exchanged by the holders for 6.125% senior notes with substantially the same terms, except that the issuance of the senior notes issued in the exchange offers was registered under the Securities Act of 1933, or Securities Act. Both series of senior notes were issued under and are entitled to the benefits of the same 2004 indenture.

The new senior notes and additional notes, or collectively, the senior notes, mature on December 1, 2014 and require semi-annual interest payments on June 1 and December 1 of each year until maturity. No principal payments are due until maturity. The senior notes are senior unsecured obligations and rank equally in right of payment with other existing and future senior indebtedness and senior in right of payment to any subordinated indebtedness that may be incurred by the Company in the future. The senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in Commission regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability or the ability of any guarantor to obtain funds from its subsidiaries by such means as a dividend or loan, except for certain restrictions contained in the Company’s revolving credit facility restricting the payment of dividends by the Company’s two principal subsidiaries. The Company may, at its option, redeem all or part of the senior notes from time to time at specified redemption prices and subject to certain conditions required by the 2004 indenture. The Company is permitted under the terms of the 2004 indenture to incur additional indebtedness in the future, provided that certain financial conditions set forth in the 2004 indenture are satisfied by the Company.

Convertible Senior Notes

On November 13, 2006, the Company issued in a private placement $250.0 million of convertible senior notes due 2026, or the convertible notes, to qualified institutional buyers pursuant to Rule 144A under the Securities Act. During the first quarter of 2007, the Company registered the resale of the convertible notes by the holders thereof. The convertible notes bear interest at an annual rate of 1.625%, declining to 1.375% beginning on November 15, 2013, payable semi-annually on May 15 and November 15 of each year, with the first interest payment payable on May 15, 2007. The convertible notes are convertible into shares of the Company’s common stock based on the applicable conversion rate only under the following circumstances:

•

during any calendar quarter (and only during such calendar quarter), if the closing price of the Company’s shares of common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is more than 135% of the conversion price per share, which is $1,000 divided by the then applicable conversion rate;

•

prior to November 15, 2013, during the five business day period after a 10 consecutive trading day period in which the trading price per $1,000 principal amount of senior subordinated convertible notes for each day of that period was less than 95% of the product of the closing price for the Company’s shares of common stock for each day of that period and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the convertible notes;

•

if the convertible notes have been called for redemption, or

•

upon the occurrence of specified corporate transactions, as defined by the convertible note agreement.

The initial conversion rate of 20.6260 shares per $1,000 principal amount of notes, which corresponds to a conversion price of approximately $48.48 per share, is based on the last reported sale price of the Company’s common shares on The New York Stock Exchange of $35.26 on November 7, 2006. As of December 31, 2007, the Company’s closing share price was $44.95.

The convertible senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in Commission regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the convertible senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability or the ability of any guarantor to obtain funds from its subsidiaries by such means as a dividend or loan, except for certain restrictions contained in the Company’s revolving credit facility restricting the payment of dividends by the Company’s two principal subsidiaries.

If, upon the occurrence of certain events, the holders of the convertible notes exercise the conversion provisions of the convertible notes, the Company may need to remit the

F-14

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

principal balance of the convertible notes to them in cash as discussed below. In such case, the Company would classify the entire amount of the outstanding convertible notes as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the convertible notes will occur every calendar quarter. Upon conversion, a holder will receive, in lieu of common stock, an amount of cash equal to the lesser of (i) the principal amount of the convertible note, or (ii) the conversion value, determined in the manner set forth in the indenture governing the convertible notes, of a number of shares equal to the conversion rate. If the conversion value exceeds the principal amount of the convertible note on the conversion date, the Company will also deliver, at the Company’s election, cash or common stock or a combination of cash and common stock with respect to the conversion value upon conversion. If conversion occurs in connection with a change of control, the Company may be required to deliver additional shares of its common stock by increasing the conversion rate with respect to such convertible notes.

In connection with the sale of the convertible notes, the Company is a party to convertible note hedge transactions with respect to its common stock with Jefferies & Company, Inc., Bear, Stearns International Limited and AIG-FP Structured Finance (Cayman) Limited, or the counterparties. Each of the convertible note hedge transactions involves the purchase of call options with exercise prices equal to the conversion price of the convertible notes, and are intended to mitigate dilution to the Company’s stockholders upon the potential future conversion of the convertible notes. Under the convertible note hedge transactions, the counterparties are required to deliver to the Company the number of shares of the Company’s common stock that the Company is obligated to deliver to the holders of the convertible notes with respect to the conversion. The convertible note hedge transactions cover approximately the same number of shares of the Company’s common stock underlying the convertible notes, subject to customary anti-dilution adjustments, at a strike price of approximately $48.48 per share of common stock. The convertible note hedge transactions expire at the close of trading on November 15, 2013, which is the date that the convertible notes are first putable by the convertible noteholders, although the counterparties will have ongoing obligations with respect to convertible notes properly converted on or prior to that date of which the counterparty has been timely notified.

The Company also entered into separate warrant transactions, whereby the Company sold to the counterparties warrants to acquire approximately the same number of shares of its common stock underlying the convertible notes, subject to customary anti-dilution adjustments, at a strike price of $62.59 per share of common stock, which represented a 77.5% premium over the closing price of the Company’s shares of common stock on November 7, 2006. If the counterparties exercise the warrants, the Company will have the option to settle in cash or shares of its common stock equal to the difference between the then market price and strike price. The convertible note hedge and warrant transactions are separate and legally distinct instruments that bind the Company and the counterparties and have no binding effect on the holders of the convertible notes.

Pursuant to Emerging Issues Task Force (EITF) Issue No. 90-19, “Convertible Bonds with Issuer Option to Settle for Cash upon Conversion,” (EITF 90-19), EITF Issue No. 00-19

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

“Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock,” (EITF 00-19), and EITF Issue No. 01-06, “The Meaning of Indexed to a Company’s Own Stock” (EITF 01-06), the convertible notes are accounted for as convertible debt in the accompanying consolidated balance sheet and the embedded conversion option in the convertible notes has not been accounted for as a separate derivative. In addition, pursuant to EITF 00-19 and EITF 01-6, the convertible note hedge and warrant transactions are accounted for as equity transactions and, therefore, the payment associated with the issuance of the convertible note hedge and the proceeds received from the issuance of the warrants were recorded as a charge and an increase, respectively, in additional paid-in capital in stockholders’ equity as separate equity transactions.

For income tax reporting purposes, the Company has elected to integrate the convertible notes and the convertible note hedge transactions. Integration of the convertible note hedge with the convertible notes creates an in-substance original issue debt discount for income tax reporting purposes and, therefore, the cost of the convertible note hedge will be accounted for as interest expense over the term of the convertible notes for income tax reporting purposes. The associated income tax benefits will be recognized in the period that the deduction is taken for income tax reporting purposes. The Company has also treated the proceeds from the sale of warrants as a non-taxable increase in additional paid-in capital in stockholders’ equity.

The Company has filed with the SEC a shelf registration statement with respect to the resale of the convertible notes and the shares of the Company’s common stock issuable upon conversion of the convertible notes. The Company has agreed to keep such shelf registration statement effective until the earlier of (i) the sale pursuant to the shelf registration statement of all of the convertible notes and/or shares of common stock issuable upon conversion of the convertible notes, and (ii) the date when the holders, other than the holders that are the Company’s affiliates, of the convertible notes and the common stock issuable upon conversion or the convertible notes are able to sell all such securities immediately without restriction pursuant to the provisions of Rule 144(k) under the Securities Act or any successor rule thereto or otherwise. The Company will be required to pay additional interest, subject to certain limitations, to the holders of the convertible notes if the Company fails to comply with its obligations to keep such shelf registration statement effective for the specified time period. The additional interest will accrue at a rate per annum equal to 0.25% for the first 90 days and 0.50% after the first 90 days after the date on which any registration statement default occurs to the date such default has been cured. As of December 31, 2007, the Company was not in default of its shelf registration requirements set forth in the convertible note agreement and has not accrued for any such additional interest.

The Company used a portion of the $243.8 million in net proceeds of the offering, along with a portion of the $51.9 million in proceeds from the sale of warrants, to fund the $75.8 million cost of convertible note hedge transactions and the $63.3 million cost to repurchase approximately 1.8 million shares of its common stock contemporaneously with the closing of the convertible notes offering. The remaining net proceeds of the convertible notes offering and the warrant transactions of approximately $156.6 million will be used for general corporate purposes, including acquisitions and additional new vessel construction.

Revolving Credit Facility

On September 27, 2006, the Company closed on a five-year senior secured revolving credit facility that increased the borrowing base, extended the maturity, lowered the interest rate and improved the financial flexibility of the covenant package of the Company’s prior revolving credit facility. The revolving credit facility initially increased the Company’s borrowing base from $60.0 million to $100.0 million, with an accordion feature that allowed for the expansion of the facility up to an aggregate of $250.0 million. The facility also extended the maturity of the prior facility from February 2009 to September 2011.

With the new facility, the Company has the option of borrowing at a variable rate of interest equal to either (i) the greater of the Prime Rate or the Federal Funds Effective Rate plus ¹/2 of 1% or (ii) the London Interbank Offered Rate, or LIBOR; plus in each case an applicable margin. The applicable margin for each base rate is determined by a pricing grid, which is based on the Company’s leverage ratio, as defined in the credit agreement governing the new revolving credit facility. The applicable LIBOR margin for the new facility ranges from 50 to 150 basis points, which is substantially less than the comparable range of the prior facility of 150 to 350 basis points. Unused commitment fees are payable quarterly at the annual rate of 17.5 to 30.0 basis points of the unused portion of the borrowing base of the new revolving credit facility, based on the defined leverage ratio.

As of December 31, 2007, the Company had posted $0.4 million in letters of credit and had $99.6 million of credit immediately available under its revolving credit facility. There were no amounts drawn on either the letters of credit or the revolving credit facility as of December 31, 2007. As of that date, eight new generation offshore supply vessels and four ocean-going tugs and associated personalty collateralized the new facility. On February 20, 2008, the Company exercised its accordion feature in full and increased the undrawn borrowing base of its revolving credit facility from $100.0 million to $250.0 million. In accordance with the terms of the new facility, the Company pledged an additional 16 new generation OSVs as collateral commensurate with the higher borrowing base. The new revolving credit facility is available for working capital and general corporate purposes, including acquisitions, additional newbuild and conversion programs and other capital expenditures.

The credit agreement governing the new revolving credit facility and the 2004 indenture governing the Company’s senior notes impose certain operating and financial restrictions on the Company. Such restrictions affect, and in many cases limit or prohibit, among other things, the Company’s ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments.

Interest expense excludes capitalized interest related to the construction or conversion of vessels in the approximate amount of $8.3 million, $2.5 million, and $3.9 million for the years ended December 31, 2007, 2006 and 2005, respectively.

7. Stockholders’ Equity

Preferred Stock

The Company’s certificate of incorporation authorizes 5.0 million shares of preferred stock. The Board of Directors has the authority to issue preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the Company’s stockholders.

Stockholder Rights Plan

On June 18, 2003, the Company’s Board of Directors implemented a stockholder rights plan, as amended on March 5, 2004 and September 3, 2004, declaring a dividend of one right for each outstanding share of common stock to stockholders of record on June 18, 2003. One right will also attach to each share of common stock issued after June 28, 2003. The rights become exercisable, and transferable apart from the Company’s common stock, 10 business days following a public announcement that a person or group has acquired beneficial ownership of, or has commenced a tender or exchange offer for, 10% or more of the Company’s common stock.

F-18

Index to Financial Statements

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The rights have anti-takeover effects, causing substantial dilution to a person or group who attempts to acquire the Company without the approval of the Board of Directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire the Company even if such acquisition may be favorable to the interests of the Company’s stockholders. Because the Board of Directors can redeem the rights or approve certain offers, the rights should not interfere with any merger or other business combination approved by the Company’s Board of Directors.

Public Offerings of Common Stock

On October 6, 2005, the Company completed an underwritten public offering, or the Offering, of 6.1 million shares of its common stock at $35.35 per share, for total gross proceeds of $215.6 million. Underwriting discounts, commissions and offering expenses of approximately $0.6 million incurred to date were recorded as a reduction of additional paid-in capital. The Offering was pursuant to the effective shelf registration statement previously filed with the Commission and included an additional 2.0 million shares sold by a selling stockholder. The Company used a portion of the net proceeds of the Offering to repay the $21 million balance then-outstanding under its revolving credit facility. The Company has used a portion of the offering proceeds and intends to use the remaining proceeds from the Offering to partially fund the construction of new OSVs, ocean-going tugs and ocean-going, double-hulled tank barges and the retrofit or conversion of certain existing vessels, including MPSVs. In addition, a part of the proceeds were used in the Sea Mar Fleet and Superior Achiever acquisitions and may be used in connection with possible future acquisitions and additional new vessel construction programs, as well as for general corporate purposes.

Repurchase of Common Stock

On November 13, 2006, the Company repurchased approximately 1.8 million shares of its common stock at a cost of $63.3 million. The stock repurchase was executed contemporaneously with the private offering of $250.0 million of 1.625% convertible senior unsecured notes due 2026 as discussed in note 6.

8. Stock-Based Compensation

Incentive Compensation Plan

The Company has an incentive compensation plan covering a maximum of 3.5 million shares of common stock that allows the Company to grant stock options, restricted stock awards and restricted stock unit awards, or collectively restricted stock, and stock appreciation rights to employees and directors. Effective January 1, 2006, the Company adopted FAS No. 123 (revised 2004), “Share-Based Payment,” or FAS 123R, using the modified prospective method. Prior to the adoption of FAS 123R, the Company accounted for stock option grants in accordance with APB 25, using the intrinsic value method, and accordingly, no compensation expense was recorded for stock option grants for periods prior to 2006.

F-19

Index to Financial Statements

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Under the modified prospective method, FAS 123R applies to new awards and to awards that were outstanding on January 1, 2006 or were repurchased or cancelled after the FAS 123R-required effective date. Additionally, compensation expense for the portion of awards for which the required service had not been rendered that were outstanding as of January 1, 2006 will be recognized as the service is rendered on or after January 1, 2006. The compensation expense for that portion of awards was based on the grant-date fair value estimated in accordance with the original provisions of FAS 123, and compensation expense for all share-based payments granted subsequent to January 1, 2006, was based on the grant-date fair value estimated in accordance with the provisions of FAS 123R. Prior periods were not restated to reflect the impact of adopting the new standard. The issuance of shares of common stock under the incentive compensation plan has been registered on Form S-8 with the Securities and Exchange Commission.

If compensation cost for the Company’s stock-based compensation plan had been determined based on the fair value at the grant dates for awards under that plan consistent with the method under SFAS 123, the Company’s net income for the year ended December 31, 2005 would have been as indicated below (in thousands, except per share data):


	Year Ended December 31, 2005
Net income:

As a result of adopting FAS 123R on January 1, 2006, the Company’s income before taxes, net income and basic and diluted earnings per share for the year ended December 31, 2007, included $7.4 million, $4.7 million, $0.18 per share and $0.18 per share of stock-based compensation expense charges, respectively. The Company’s income before taxes, net income and basic and diluted earnings per share for the year ended December 31, 2006, included $5.2 million, $3.3 million, $0.12 per share and $0.12 per share of stock-based compensation expense charges, respectively.

2006, approximately $1.1 million and $0.2 million of stock-based compensation expense, respectively, was capitalized as part of the Company’s newbuild construction programs and general corporate projects. FAS 123R also requires the benefits of tax deductions in excess of recognized compensation expense to be reported as financing cash flows, rather than as operating cash flows as required under previous accounting literature. The Company recorded financing cash flows for such excess tax deductions of approximately $1.2 million and $1.4 million for the years ended December 31, 2007 and 2006, respectively. Net cash proceeds from the exercise of stock options were $2.3 million and $2.1 million for the years ended December 31, 2007 and 2006, respectively, and the income tax benefit from such exercises was $1.1 million and $1.5 million for the respective periods. As of December 31, 2007, the Company has approximately 0.9 million shares available for future grants of stock options, restricted stock units, stock appreciation rights or other awards to employees and directors under the incentive compensation plan.

Stock Options

The Company is authorized to grant stock options under its incentive compensation plan in which the purchase price of the stock subject to each option is established as the closing price on the New York Stock Exchange of the Company’s common stock on the date of grant and accordingly is not less than the fair market value of the stock on the date of grant. All options granted during both of the years ended December 31, 2006 and 2005 expire ten years after the date of grant, have an exercise price equal to or greater than the actual or estimated market price of the Company’s stock on the date of grant and vest over a one to four-year period. No stock options were granted during the year ended December 31, 2007.

The fair value of the options granted under the Company’s incentive compensation plan during both of the years ended December 31, 2006 and 2005 was estimated using the Black-Scholes pricing model using the minimum value method with the following weighted-average assumptions for the respective periods.

Restricted Stock

The Company’s incentive compensation plan allows the Company to issue restricted stock and restricted stock units, collectively restricted stock awards, with either performance-based or time-based vesting provisions. The Company has issued two types of performance-based restricted stock awards whose vesting is determined by achieving either external or internal performance criteria. For the first type of performance-based restricted stock award, the number of shares that will ultimately be received by the award recipients at the end of the performance period is dependent upon the Company’s performance relative to a peer group, as defined by the restricted stock agreements governing such awards. Performance is measured by the change in the Company’s stock price measured against the peer group during the measurement period, generally three years. The actual number of shares that could be received by the award recipients can range from 0% to 200% of the Company’s base share awards depending on the Company’s performance ranking relative to the peer

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

group. The second type of performance-based restricted stock award, calculates the shares to be received based on the Company’s achievement of certain performance criteria over a three year period as defined by the restricted stock agreement governing such awards. The actual number of shares that could be received by these award recipients can range from 0% to 100% of the Company’s base share awards depending on the number of performance goals attained by the Company. Compensation expense related to restricted stock awards is recognized over the period the restrictions lapse, from one to three years. The fair value of the Company’s performance-based restricted stock awards, which is determined using a binomial lattice model, is applied to the base shares and is amortized over the vesting period based on either their relative performance compared to peers or internal performance goals attained. The compensation expense related to time-based restricted stock awards, which is amortized over the vesting period, is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. As of December 31, 2007, the Company had unamortized stock-based compensation expense of $10.5 million and has recorded approximately $6.2 million of compensation expense during the year ended December 31, 2007, respectively, associated with restricted stock awards.

The following table summarizes the restricted stock awards activity during the year ended December 31, 2007 (in thousands):

Employee Stock Purchase Plan

On May 3, 2005, the Company established the Hornbeck Offshore Services, Inc. 2005 Employee Stock Purchase Plan, or ESPP, which was adopted by the Company’s Board of Directors and approved by the Company’s stockholders. Under the ESPP, the Company is authorized to issue up to 700,000 shares of common stock to eligible employees of the Company and its designated subsidiaries. Employees have the opportunity to purchase shares of the Company’s common stock at periodic intervals through accumulated payroll deductions that will be applied at semi-annual intervals to purchase shares of common stock at a discount from the market price as defined by the ESPP. The ESPP is designed to satisfy the requirements of Section 423 of the Internal Revenue Code of 1986, as amended, and thereby allows participating employees to defer recognition of taxes when purchasing the shares of common stock at a 15% discount under the ESPP. On May 6, 2005, the Company filed a Registration Statement on Form S-8 with the Commission to register the issuance of

F-23

10. Commitments and Contingencies

Vessel Construction

On May 5, 2005, the Company announced a conversion program to retrofit two coastwise sulfur tankers into U.S.-flagged, proprietary 370 class DP-2 new generation multi-purpose support vessels, or MPSVs. The Company has contracted for the conversion of these two vessels at a domestic shipyard and anticipates delivery of the converted vessels during the third quarter of 2008 and late 2008 or early 2009, respectively. In May 2007 and January 2008, the Company announced the expansion of its MPSV program to include the newbuild construction of two Merwede T-22 class DP-3 new generation MPSVs at a foreign shipyard, with anticipated deliveries of the fourth quarter 2008 and fourth quarter 2009, respectively. Based on internal estimates, the total project cost to acquire and convert the two DP-2 MPSVs and construct the two DP-3 MPSVs, prior to construction period interest, is expected to be approximately $450.0 million in the aggregate. As of December 31, 2007, the Company had incurred construction and conversion costs of approximately $145.9 million since the inception of the MPSV program.

In September 2005, the Company announced, and has since expanded, its fourth OSV newbuild program. The Company is currently committed under vessel construction contracts with three domestic shipyards to build six proprietary 240 ED class OSVs, nine proprietary 250 EDF class OSVs and one 285 class new generation OSV, respectively. Projected delivery dates for these 16 DP-2 vessels range from 2008 through 2010. Based on current contracts and internal estimates, the aggregate total cost of this program, before construction period interest, is expected to be approximately $393.0 million. As of December 31, 2007, the Company had incurred construction costs of approximately $93.6 million since the inception of its fourth OSV newbuild program. See note 18 for further discussion of the expansions to the Company’s MPSV program and fourth OSV newbuild program.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In September 2005, the Company announced its second tug and tank barge, or TTB, newbuild program and announced an expansion to such program in August 2006. Under this newbuild program, two retrofitted ocean-going tugs, Michigan Service and Huron Service, were delivered in July 2007 and November 2007, respectively, and two newbuild double-hulled tank barges, Energy 6506 and Energy 6507, were delivered in August 2007 and November 2007, respectively. As of December 31, 2007, the Company was committed under vessel construction contracts with one domestic shipyard to build the remaining 60,000-barrel double-hulled barge under this program and another domestic shipyard for the retrofit of the two remaining 3,000 horsepower ocean-going tugs that were purchased in July 2006. The acquisition, retrofit and construction costs for these seven vessels are expected to be $77.0 million, in the aggregate. The retrofitted ocean-going tug, Superior Service, and newbuild double-hulled tank barge, Energy 6508, were delivered during the first quarter of 2008. The final remaining vessel under this program is expected to be delivered during the second quarter of 2008. As of December 31, 2007, the Company had incurred construction costs of approximately $69.0 million since the inception of its second TTB newbuild program.

Operating Leases

As of December 31, 2007, the Company is obligated under certain operating leases for marine vessels, office space, shore-based facilities and vehicles. The Company is currently committed to leases for three tugs with terms of four months, one year and three years, respectively. The Covington facility lease, which commenced in September 2003, provides for an initial term of five years with two five-year renewal options. In March 2008, the Company intends to exercise its first five-year renewal option with respect to its corporate headquarters in Covington and renew the lease of its Brooklyn facility for an additional year. A shore-based facility lease in Port Fourchon commenced on December 20, 2005 and provides for an initial term of seven years with four additional five-year periods upon the terms and conditions contained in the lease agreement.

Future minimum payments under noncancelable leases for years subsequent to 2007 follow (in thousands):

In addition, the Company leases marine vessels used in its operations under long-term and month-to-month operating lease agreements. Total rent expense related to such leases was approximately $9.4 million, $7.8 million, and $1.2 million during the years ended December 31, 2007, 2006 and 2005, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Contingencies

In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. It is management’s opinion that the Company’s liability, if any, under such claims or proceedings would not materially affect its financial position or results of operations.

In early 2007, several actions were filed in the United States District Court on behalf of certain plaintiffs and other similarly situated purchasers of the Company’s securities from November 1, 2006 to January 10, 2007. In their complaints, the plaintiffs alleged that Hornbeck Offshore Services, Inc. and certain of its senior executive officers violated Section 10(b) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, by allegedly making false and misleading statements, and/or by omitting to state material facts necessary to make the statements not misleading, in connection with its forward earnings guidance and its January 10, 2007 announcement of preliminary financial results for the fourth quarter of 2006 that fell short of such guidance and indicated a reduction in 2007 guidance. The Company and such officers vigorously denied those allegations and believe that the actions were without merit. Prior to September 2007, the lawsuits were consolidated into a single proceeding with the plaintiffs seeking certification as a class. In September 2007, the purported class action lawsuit against the Company and such officers, was voluntarily dismissed by the lead plaintiffs without any payment by the Company, its officers or its insurers. An order granting the dismissal of the case without prejudice was entered by the United States District Court for the Eastern District of Louisiana.

The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 27 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity association, or P&I Club. In March 2006, the terms of entry for both of the Company’s segments contained an annual aggregate deductible (AAD) for which the Company remains responsible, while the P&I Club is responsible for all applicable amounts that exceed the AAD, after payment by the Company of an additional individual claim deductible. The Company provides reserves for those portions of the AAD and any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel. As additional information becomes available, the Company will assess the potential liability related to its pending litigation and revise its estimates. Such revisions in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows. As of December 31, 2007, the Company’s claims reserves related to one of its segments incurred under its P&I Club policies have exceeded the AAD for the current policy year.

14. Segment Information

The Company provides marine transportation and logistics services through two business segments. The Company primarily operates new generation OSVs in the U.S. Gulf of Mexico, or GoM, other U.S. coastlines, Trinidad, Mexico, and Qatar and operates a shore-based facility in Port Fourchon, Louisiana through its OSV segment. The OSVs and the shore-based facility principally support complex exploration and production projects by transporting cargo to offshore drilling rigs and production facilities and provide support for oilfield and non-oilfield specialty services, including military applications. The TTB segment primarily operates ocean-going tugs and tank barges in the northeastern United States, GoM, Great Lakes and Puerto Rico. The ocean-going tugs and tank barges provide coastwise transportation of refined and bunker grade petroleum products as well as non-traditional TTB services, such as support of deepwater well testing and other specialty applications for the Company’s upstream customers.

17. Sea Mar Fleet Acquisition

On July 20, 2007, the Company entered into a definitive asset purchase agreement to acquire 20 offshore supply vessels, or OSVs, and their related business, or the Sea Mar Fleet, from certain affiliates of Nabors Industries, Ltd., or Nabors, for $186.0 million in cash, plus the cost of the fuel inventory on such vessels. The Company also agreed to purchase one newbuild 285 class DP-2 vessel currently under construction with an anticipated late-2008 delivery. The expected cost of this vessel, prior to the allocation of construction period interest, is approximately $34.0 million, of which $7.3 million was paid to Nabors at closing. The acquisition closed on August 8, 2007. The Company did not record any goodwill as a result of the acquisition. The Company recorded accrued liabilities of approximately $8.0 million related to the estimated cost of the regulatory drydocking of acquired vessels expected to be completed within the allocation period and an estimated pre-acquisition contingency for personnel costs. As of December 31, 2007, the purchase price was allocated to the acquired assets based on the estimated fair values as follows (in thousands):


Property, plant and equipment	$	193,955
Construction work in progress		7,300
Inventory		1,000
Accrued liabilities		(7,955	)

Purchase price	$	194,300

18. Subsequent Events

On January 9, 2008, the Company entered into a definitive asset purchase agreement with Superior Offshore International, Inc., or Superior, to acquire the Superior Achiever, a T-22 class DP-3 new generation MPSV and related owner-furnished equipment, currently under construction at Merwede Shipyard in Holland with an anticipated fourth quarter 2008 delivery. The Company also agreed to a five-year time charter with Superior for the Superior Achiever or another acceptable vessel at a dayrate of $100,000. Superior will have the option to terminate the charter with 90-days' advance notice at the end of each sequential six-month period within the term. The definitive agreement also provides that Hornbeck and Superior will agree to negotiate in good faith toward the establishment of a non-exclusive joint marketing and cooperation agreement and that the parties will endeavor to seek mutually beneficial business opportunities utilizing their complementary resources. The Superior Achiever acquisition closed on January 22, 2008.

On January 9, 2008, the Company announced plans to expand its fourth OSV newbuild program. The Company contracted for the construction of two additional proprietary 240 ED class OSVs with Atlantic Marine in Jacksonville, Florida, which is the same U.S. shipyard that is currently building four identical "sister vessels" for the Company. The two new vessels are anticipated to be delivered in 2010.

On January 30, 2008, the Company purchased a leasehold interest in a parcel of improved real estate adjacent to HOS Port, its existing shore-base facility located in Port Fourchon, Louisiana. The new facility lease has approximately seven years remaining on its initial term, with four additional five-year renewal periods.

The Company plans to fund the incremental expected cost of these January 2008 transactions of approximately $190 million in the aggregate, along with its previously announced newbuild and conversion programs, from cash on hand, projected cash flows from operations and an expanded revolving credit facility. In conjunction with these transactions, on February 20, 2008, the Company exercised the accordion feature of such revolving credit facility and increased the borrowing base to $250 million, up from $100 million as of December 31, 2007.
