Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

Represents the noncurrent portion of deferred tax liabilities, which result from applying the applicable tax rate to net taxable temporary differences pertaining to each jurisdiction to which the entity is obligated to pay income tax. A noncurrent taxable temporary difference is a difference between the tax basis and the carrying amount of a noncurrent asset or liability in the financial statements prepared in accordance with generally accepted accounting principles. In a classified statement of financial position, an enterprise separates deferred tax liabilities and assets into a current amount and a noncurrent amount. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. A deferred tax liability or asset that is not related to an asset or liability for financial reporting, including deferred tax assets related to carryforwards, are classified according to the expected reversal date of the temporary difference.

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

The Company, through its subsidiaries, operates offshore supply vessels, or OSVs, multi-purpose support vessels, or MPSVs, and a shore-base facility 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, Latin America 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. |

| Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Revenue Recognition The Company charters its OSVs, MPSVs 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 or billings submitted to 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 and amounts to be rebilled to customers. Property, Plant and Equipment Property, plant and equipment is 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 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. Salvage values for marine equipment are estimated to range between 5% and 25% of the originally recorded cost, depending on the vessel type. The estimated useful lives by classification are as follows:
All of the Company’s single-hulled tank barges, which have been sold, had 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. Assets having shorter useful lives primarily relate to acquired vessels. See “Impairment of Long-Lived Assets” below for more information. 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 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-base port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease. Mobilization Costs The Company incurs mobilization costs to transit its vessels to and from certain regions and/or for long-term contracts. These costs, which are typically expensed as incurred, include, but are not limited to, fuel, crew wages, vessel modification and pre-positioning expenses, materials and supplies and importation taxes. The Company incurred mobilization costs of $9.5 million and $9.7 million during 2011 and 2010, respectively, associated with the mobilization and pre-positioning of vessels to foreign locations. 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.
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. Interest and penalties relating to uncertain tax positions are recorded as general and administrative expenses. In addition, the Company provides a valuation allowance for deferred tax assets if it is more likely than not that such items will either expire before the Company is able to realize the benefit or the future deductibility is uncertain. No valuation allowances were recorded for the years ended December 31, 2011, 2010 or 2009. 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. Legal Liabilities In the ordinary course of business, the Company may become party to lawsuits, administrative proceedings, or governmental investigations. These matters may involve large or unspecified damages or penalties that may be sought from the Company and may require years to resolve. The Company records a liability related to a loss contingency to such legal matters in accrued liabilities if the Company determines the loss to be both probable and estimable. The liability is recorded for an amount that is management’s best estimate of the loss, or when a best estimate cannot be made, the minimum loss amount of a range of possible outcomes. Significant judgment is required in estimating such liabilities, the results of which can vary significantly from the actual outcomes of lawsuits, administrative proceedings or governmental investigations. Concentration of Credit Risk Customers are primarily major and independent, domestic and international, oil and oil service companies, as well as national oil 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):
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. See Note 14 for further information. Recent Accounting Pronouncements In September 2011, the Financial Accounting Standards Board, or FASB, issued guidance that simplified how entities test for goodwill impairment. This guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a two-step goodwill impairment test. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, and early adoption is permitted. We adopted this guidance for our annual goodwill impairment test that was conducted as of November 30, 2011. This guidance is not expected to have a material effect on our financial condition or results of operations. In June 2011, the FASB issued new guidance regarding the presentation of comprehensive income. This guidance eliminates the option to present the components of other comprehensive income, or OCI, as part of the statement of stockholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income, which contains two sections, net income and OCI, or in two separate but consecutive statements. In each case, the entity is required to present reclassification adjustments on the face of the financial statements for items that are reclassified from OCI to net income in the statement where those components are presented. The amendments do not change the items that must be reported in OCI or when an item of OCI must be reclassified to net income. This new guidance is effective for interim and annual periods beginning after December 15, 2011. In October 2011, the FASB announced it would defer the effective date of the requirement to present reclassifications from OCI to net income on the face of the financial statements. However, it did not change the requirement to present net income, components of OCI, and total comprehensive income in either one continuous statement or two separate consecutive statements. The Company elected to early adopt this new guidance effective for the year ended December 31, 2011 and has presented components of OCI in two consecutive statements. The Company does not believe the adoption of the remainder of this guidance will have a material impact on its consolidated financial statements. Management does not expect other accounting standards that have been issued by the FASB or other standards-setting bodies to have a material impact on the Company’s financial position, results of operations or cash flows. |

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.

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 profit sharing contributions to the 401(k) plan. During the years ended December 31, 2011, 2010 and 2009, the Company made contributions to the 401(k) plan of approximately $0.6 million, $2.9 million, and $2.9 million, respectively. Contributions declined in 2011 because the Company temporarily suspended its 401(k) discretionary match from March 2011 through December 2011 in an effort to manage costs during the de facto regulatory moratorium in the GoM. |

| Property, Plant and Equipment | 5. Property, Plant and Equipment Property, plant and equipment consisted of the following (in thousands):
During 2011, the Company announced its fifth OSV newbuild program, which consists of vessel construction contracts with two domestic shipyards to build four 300 class OSVs, four 310 class OSVs, and eight 320 class OSVs. Delivery of the first 16 vessels to be constructed under this program is expected to occur on various dates during 2013 and 2014. The Company expects to own and operate 51, 56 and 67 new generation OSVs as of December 31, 2012, 2013 and 2014, respectively. These vessel additions result in a projected average new generation OSV fleet complement of 51.0, 52.2 and 62.8 vessels for the fiscal years 2012, 2013 and 2014, respectively. The aggregate cost of the Company’s fifth OSV newbuild program, excluding construction period interest, is expected to be approximately $720.0 million. From the inception of this program through December 31, 2011, the Company has incurred $42.4 million, or 5.9%, of total expected project costs. During 2010, the Company completed its fourth OSV newbuild program and its MPSV program. The Company’s fourth OSV newbuild program consisted of vessel construction contracts with three domestic shipyards to build six 240 ED class OSVs, nine 250 EDF class OSVs and one 290 class OSV. These vessels were delivered on various dates from 2008 to 2010. The aggregate cost, prior to the allocation of construction period interest, of the fourth OSV newbuild program was approximately $431.6 million. The Company’s MPSV program consisted of the conversion of two coastwise sulfur tankers into U.S.-flagged, proprietary 370 class DP-2 new generation MPSVs at domestic shipyards, and the newbuild construction of two 430 class DP-3 new generation MPSVs at foreign shipyards. These vessels were delivered on various dates from 2008 to 2010. The aggregate cost of the MPSV program, prior to the allocation of construction period interest, was approximately $491.1 million. |

| Long-Term Debt | 6. Long-Term Debt Senior Notes On November 23, 2004, the Company issued in a private placement $225.0 million in aggregate principal amount of 6.125% senior unsecured notes due 2014, or senior notes, governed by an indenture, or the 2004 indenture. The effective interest rate on the 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 unsecured 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 senior notes and additional notes, collectively, the 2014 senior notes, mature on December 1, 2014 and require semi-annual interest payments at a fixed annual rate of 6.125%, or approximately $9.2 million semi-annually, on June 1 and December 1 of each year until maturity. No principal payments are due until maturity. Pursuant to registered exchange offers, the 2014 senior 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, as amended, or the Securities Act. Both series of 2014 senior notes were issued under and are entitled to the benefits of the same 2004 indenture. On August 17, 2009, the Company issued in a private placement $250.0 million in aggregate principal amount of 8.000% senior unsecured notes due 2017, or 2017 senior notes, governed by an indenture, or the 2009 indenture. The net proceeds to the Company from the offering were approximately $237.3 million, net of original issue discount and estimated transaction costs. The Company used $200.0 million of proceeds to repay debt under its revolving credit facility, which may be reborrowed. The remaining proceeds were available for general corporate purposes, which include partial funding of the construction of vessels under existing newbuild programs. The 2017 senior notes mature on September 1, 2017 and require semi-annual interest payments at a fixed annual rate of 8.000%, or $10.0 million semi-annually, on March 1 and September 1 of each year until maturity, with the first interest payment made on March 1, 2010. The effective interest rate on the 2017 senior notes is 8.63% and no principal payments are due until maturity. Pursuant to a registered exchange offer, the 2017 senior notes issued in August 2009 that were initially sold pursuant to a private placement were exchanged by the holders for 8.000% senior notes with substantially the same terms, except that the issuance of the senior notes issued in the exchange offer was registered under the Securities Act of 1933, as amended, or the Securities Act. The original 2017 senior notes and the similar notes exchanged therefor were issued under and are entitled to the benefits of the same 2009 indenture. The 2014 senior notes and 2017 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. These 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 the Securities and Exchange Commission, or Commission, regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of these 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 2014 senior notes or 2017 senior notes from time to time at specified redemption prices and subject to certain conditions required by the indentures. The Company is permitted under the terms of the indentures to incur additional indebtedness in the future, provided that certain financial conditions set forth in the indentures are satisfied by the Company. Convertible Senior Notes On November 13, 2006, the Company issued in a private placement $250.0 million in aggregate principal amount of 1.625% 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 a fixed 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 made on May 15, 2007. The effective interest rate on such notes is 6.36%. The convertible notes are convertible into shares of the Company’s common stock based on the applicable conversion rate only under the following circumstances:
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, 2011, the Company’s closing share price was $31.02. 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. The convertible notes are general unsecured, senior obligations of the Company, ranking equally in right of payment with all of its existing and future senior indebtedness, including its outstanding 6.125% senior notes due 2014, 8.000% new senior notes due 2017, and indebtedness under its revolving credit facility. 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 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., JP Morgan Chase 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 $48.48 per share of common stock, which represented a 37.5% premium over the closing price of the Company’s shares of common stock on November 7, 2006. 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. In addition, on November 15, 2016 and November 15, 2021, holders of the 1.625% convertible senior notes may require the Company to purchase their notes for cash.
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. 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 is accounted for as interest expense over the term of the convertible notes for income tax reporting purposes. The associated income tax deductions 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. Revolving Credit Facility On September 27, 2006, the Company closed on a five-year senior secured $100.0 million revolving credit facility with an accordion feature that allowed for the expansion of the facility up to an aggregate of $250.0 million. On February 20, 2008, the Company exercised its accordion feature in full and increased the then-undrawn borrowing base of its revolving credit facility from $100.0 million to $250.0 million. In accordance with the terms of the expanded facility, the Company pledged an additional 16 new generation OSVs as collateral commensurate with the higher borrowing base. On November 4, 2009, the Company amended and extended its revolving credit facility, which maintained its $250.0 million borrowing base but included an accordion feature that allowed for the expansion of the facility up to an aggregate of $350.0 million. The amended facility, among other changes, also extended the maturity from September 2011 to March 2013. With the amended facility, the Company had the option of borrowing at a variable rate of interest equal to either (i) LIBOR, plus an applicable margin, or (ii) the greatest of the Prime Rate, the Federal Funds Effective Rate plus 1/2 of 1%, and the one-month LIBOR plus 1%, 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 amended revolving credit facility. Unused commitment fees were payable quarterly at the annual rate of 50.0 basis points of the unused portion of the borrowing base of the amended facility. The Company also exchanged certain vessels pledged as collateral under the amended revolving credit facility such that the total number of vessels pledged as collateral was 19 new generation OSVs. None of the Company’s Downstream vessels were pledged under the November 2009 amended and extended facility or any subsequent amendments.
On March 14, 2011, the Company amended the credit agreement governing its revolving credit facility to favorably adjust certain financial ratios and provide for additional new maintenance covenants. The key changes to the Company’s revolving credit facility were effective commencing with the fiscal quarter ended December 31, 2010 and are noted below:
On November 2, 2011, the Company further amended and restated its revolving credit facility, which increased its borrowing base to $300.0 million and included an accordion feature that allows for the potential expansion of the facility up to an aggregate of $500.0 million. The key changes to the Company’s revolving credit facility were effective commencing with the fiscal quarter ended September 30, 2011 and are noted below:
Other than these key changes, all other definitions and substantive terms in the Company’s credit agreement governing its revolving credit facility were unchanged with the November 2011 amendment and remain in effect through the remaining life of the facility. As of December 31, 2011, there were no amounts drawn under the Company’s $300.0 million revolving credit facility and $0.9 million posted in letters of credit. As of December 31, 2011, the Company was in compliance with all financial covenants contained in its amended revolving credit facility. The credit agreement governing the amended revolving credit facility and the indentures governing the Company’s 2014 senior notes and 2017 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. The Company estimates the fair value of its 6.125% senior notes due 2014, its 8.000% senior notes due 2017 and its 1.625% convertible senior notes due 2026 by using quoted market prices. The fair value of the Company’s revolving credit facility, when there are outstanding balances, approximates its carrying value. The face value, carrying value and fair value of the Company’s total debt was $800.0 million, $770.6 million and $810.3 million, respectively, as of December 31, 2011. Interest expense excludes capitalized interest related to the construction or conversion of vessels in the approximate amount of $0.4 million, $3.7 million, and $23.8 million, for the years ended December 31, 2011, 2010, and 2009, respectively.
As of the dates indicated below, the Company had the following outstanding long-term debt (in thousands):
Annual maturities of debt, excluding the potential effects of conditions discussed in Convertible Senior Notes, during each year ending December 31, are as follows (in thousands):

| Stockholders' Equity | 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 The Company’s Board of Directors previously implemented a stockholder rights plan, as amended, establishing one right for each outstanding share of common stock. 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. Public Offerings of Common Stock On November 16, 2011, the Company completed an underwritten public offering of 8.1 million shares of its common stock at $30.00 per share, for total gross proceeds of $241.5 million before underwriting discounts, commissions and offering expenses. This includes 1,050,000 additional shares of common stock purchased pursuant to the exercise in full of the underwriters’ over-allotment option. Underwriting discounts, commissions and offering expenses of approximately $11.4 million were recorded as a reduction of additional paid-in capital. The Company intends to use net proceeds from the offering to partially fund its fifth OSV newbuild program. In addition, offering proceeds may be used in connection with possible future acquisitions and additional new vessel construction, as well as for general corporate purposes. |

| Stock-Based Compensation | 8. Stock-Based Compensation Incentive Compensation Plan During the Company’s Annual Meeting of Stockholders in June 2010, the Company’s stockholders approved an increase in the number of shares available to issue under its stock-based incentive compensation plan by 700,000. The Company’s stock-based incentive compensation plan now covers a maximum of 4.2 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options and stock appreciation rights to employees and directors. 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. The table below reflects selected financial captions and the related impact stock-based compensation expense charges have on the Company’s operating results (in thousands, except per share data):
For the years ended December 31, 2010, and 2009, approximately $0.4 million, and $1.1 million of stock-based compensation expense, respectively, was capitalized as part of the Company’s newbuild construction programs and general corporate projects. No such stock-based compensation expense was capitalized during the year ended December 31, 2011. The accounting rules also require the benefits of tax deductions in excess of recognized compensation expense to be reported as financing cash flows, rather than as operating cash flows. The Company recorded financing cash flows for such excess tax deductions of approximately $0.4 million, $0.4 million, and $0.2 million for the years ended December 31, 2011, 2010, and 2009, respectively. Net cash proceeds from the exercise of stock options were $0.6 million, $0.6 million, and $1.0 million for the years ended December 31, 2011, 2010, and 2009, respectively. The income tax benefit from stock option exercises and restricted stock vesting was $2.0 million, $2.7 million, and $1.3 million for the respective periods. As of December 31, 2011, the Company has approximately 0.8 million shares available for future grants of stock options, restricted stock, stock appreciation rights or other awards to officers, 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 the year ended December 31, 2011 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 three-year period. Stock options were granted to executive officers of the company during 2011. No stock options were granted during 2010 and 2009. The fair value of the options granted under the Company’s incentive compensation plan during the year ended December 31, 2011 was estimated using the Black-Scholes pricing model with the following weighted-average assumptions for the respective option periods.
The following table represents the Company’s stock option activity for the year ended December 31, 2011 (in thousands, except per share data and years):
The following table represents the Company’s nonvested stock option activity for the year ended December 31, 2011 (in thousands, except per share data):
As of December 31, 2011, the Company had unamortized stock-based compensation expense of $1.8 million that will be recognized on a straight-line basis over the remaining vesting period, or 1.5 years, and has recorded approximately $0.7 million of compensation expense during 2011, respectively, associated with stock options. Restricted Stock The Company’s incentive compensation plan allows the Company to issue restricted stock units, with either performance-based or time-based vesting provisions. The Company has issued two types of performance-based restricted stock unit awards whose vesting is determined by achieving either external or internal performance criteria. For the first type of performance-based restricted stock unit 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 unit agreements governing such awards. Performance for such types of awards has historically been 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 group. This type of performance-based restricted stock unit was granted in 2011. The second type of performance-based restricted stock unit 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 unit agreement governing such awards. Performance for these types of awards has historically been measured by a number of factors, including the Company achieving a targeted return on invested capital, return on equity, Upstream operating profit margin and growth in earnings (net income) before interest, income taxes, depreciation and amortization or EBITDA. 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 unit 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 unit awards, which is determined using a Monte Carlo simulation, 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 unit awards, which is amortized over a one to four-year 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, 2011, the Company had unamortized stock-based compensation expense of $7.5 million, which will be recognized on a straight-line basis over the remaining vesting period, or 1.5 years. In addition, the Company has recorded approximately $5.4 million of compensation expense during the year ended December 31, 2011 associated with restricted stock unit awards. The following table summarizes the restricted stock awards activity during the year ended December 31, 2011 (in thousands, except per share data):
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. The Company has an effective Registration Statement on Form S-8 with the Commission registering the issuance of shares of common stock under the ESPP. As of December 31, 2011, there were 358,666 shares available for future issuance to employees under the ESPP. The Company has recorded approximately $0.4 million of compensation expense during the year ended December 31, 2011 associated with the ESPP. The fair value of the employees’ stock purchase rights granted under the ESPP was estimated using the Black-Scholes model with the following assumptions for years ended December 31, 2011 and 2010:

| Commitments and Contingencies | 10. Commitments and Contingencies Operating Leases The Company is obligated under certain operating leases for marine vessels, office space, shore-base facilities and vehicles. The Covington facility lease, which commenced on September 1, 2003, provides for an initial term of five years with two five-year renewal options. In September 2008, the Company exercised its first five-year renewal option. A shore-base 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. On January 30, 2008, the Company purchased a leasehold interest in a parcel of improved real estate as an adjacent addition to HOS Port, its existing shore-base facility located in Port Fourchon, Louisiana. At December 31, 2011, the new facility lease had approximately three years remaining on its initial term, with four additional five-year renewal periods. Future minimum payments under noncancelable leases for years subsequent to 2011 are as follows (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 $0.2 million during the year ended December 31, 2009. The Company did not have any rent expense related to such vessels during the years ended December 31, 2010 and 2011.
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. The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 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, as well as by marine liability policies in excess of the P&I Club’s coverage. In February 2011 and 2010, the terms of entry for our Downstream segment contained an annual aggregate deductible, or AAD, for which the Company remains responsible. The P&I Club is responsible for covered 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 claims and revise its estimates. Although historically revisions to such estimates have not been material, changes in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows. As of December 31, 2011, the Company’s claims incurred under its P&I Club policies have not exceeded the AAD for the 2011 or 2010 policy years. During 2010 and 2011, the Company mobilized 12 vessels, in the aggregate, to Brazil to operate under long-term contracts for Petrobras. These vessels required a significant amount of modifications to comply with requirements of the contracts. The Company has been assessed penalties by Petrobras for late-deliveries. In addition, these vessel charters with Petrobras include limitations regarding fuel consumption. Petrobras has asserted claims against the Company relating to excess fuel consumption. The Company’s exposure for these assessments, net of amounts accrued, is in the range of approximately $0.5 million to $8.0 million. The Company disagrees with a majority of these assessments. In addition, the Company also has claims against Petrobras for their contributory actions related to the vessels’ late deliveries. Such claims exceed the maximum exposure noted above. The Company is not able to predict the ultimate outcome of these claims and counterclaims with Petrobras as of December 31, 2011. While the Company cannot currently estimate the amounts or timing of the resolution of these matters, the Company believes that the outcome will not have a material impact on its liquidity or financial position, but the ultimate resolution could have material impact on its interim or annual results of operations. |

| Asset and Goodwill Impairment Assessment | 14. Asset and Goodwill Impairment Assessment In the second quarter of 2009, triggering events occurred that resulted in the Company performing impairment tests on its Downstream segment assets, as well as the conventional OSVs in its Upstream Segment. This analysis resulted in the Company recording a non-cash asset impairment charge of $25.8 million, included in depreciation expense, related to ten single-hulled tank barges and six ocean-going tugs, and a $0.9 million non-cash charge, included in amortization expense, for the write-off of remaining goodwill associated with the Company’s Downstream segment. Based on the analysis performed, no impairment existed for any of the Company’s conventional OSVs. The specific triggering events were the Downstream segment operating loss for the quarter ended June 30, 2009, the lack of any material new contracts for the Downstream segment since March 31, 2009, and the lack of any expected change in performance in that segment in the near term. As of June 30, 2009, the Company had stacked all of its conventional OSVs, which it considered to be a triggering event for those specific assets. The impairment assessment compared the net book values of the Company’s Downstream marine assets, as well as Downstream segment goodwill that was booked upon the Company’s formation in June 1997, to their respective fair values. The analysis performed during the second quarter of 2009 included considering recent vessel sales, quoted market prices and past third-party appraisals. No further impairment for the Company’s vessels was deemed necessary as of December 31, 2011, 2010, and 2009. No new triggering events have occurred since June 30, 2009. The Company considered whether the curtailed level of drilling activity in the GoM represented an indicator of impairment for any of its asset groups and concluded it did not. Some factors that the Company considered were the anticipated temporary nature of the reduced drilling activity, projected operating results for assets groups, the significant remaining operating useful life, mobility and flexibility of the Company’s vessels. The Company did not record any impairment losses related to its long-lived assets during 2010 or 2011. As of December 31, 2011 and 2010, the Company’s Other Assets included approximately $1.7 million of goodwill related to its Upstream segment. |

| Revenue Recognition | Revenue Recognition The Company charters its OSVs, MPSVs 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 or billings submitted to customers in advance of vessels commencing time charters. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents | 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 Accounts receivable consists of trade receivables net of reserves and amounts to be rebilled to customers. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment is 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 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. Salvage values for marine equipment are estimated to range between 5% and 25% of the originally recorded cost, depending on the vessel type. The estimated useful lives by classification are as follows:
All of the Company’s single-hulled tank barges, which have been sold, had 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. Assets having shorter useful lives primarily relate to acquired vessels. See “Impairment of Long-Lived Assets” below for more information. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deferred Charges | 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 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-base port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Mobilization Costs | Mobilization Costs The Company incurs mobilization costs to transit its vessels to and from certain regions and/or for long-term contracts. These costs, which are typically expensed as incurred, include, but are not limited to, fuel, crew wages, vessel modification and pre-positioning expenses, materials and supplies and importation taxes. The Company incurred mobilization costs of $9.5 million and $9.7 million during 2011 and 2010, respectively, associated with the mobilization and pre-positioning of vessels to foreign locations. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes | 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.
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. Interest and penalties relating to uncertain tax positions are recorded as general and administrative expenses. In addition, the Company provides a valuation allowance for deferred tax assets if it is more likely than not that such items will either expire before the Company is able to realize the benefit or the future deductibility is uncertain. No valuation allowances were recorded for the years ended December 31, 2011, 2010 or 2009. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates | 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. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Legal Liabilities | Legal Liabilities In the ordinary course of business, the Company may become party to lawsuits, administrative proceedings, or governmental investigations. These matters may involve large or unspecified damages or penalties that may be sought from the Company and may require years to resolve. The Company records a liability related to a loss contingency to such legal matters in accrued liabilities if the Company determines the loss to be both probable and estimable. The liability is recorded for an amount that is management’s best estimate of the loss, or when a best estimate cannot be made, the minimum loss amount of a range of possible outcomes. Significant judgment is required in estimating such liabilities, the results of which can vary significantly from the actual outcomes of lawsuits, administrative proceedings or governmental investigations. |

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):

| Impairment of Long-Lived Assets | 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. See Note 14 for further information. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In September 2011, the Financial Accounting Standards Board, or FASB, issued guidance that simplified how entities test for goodwill impairment. This guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a two-step goodwill impairment test. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, and early adoption is permitted. We adopted this guidance for our annual goodwill impairment test that was conducted as of November 30, 2011. This guidance is not expected to have a material effect on our financial condition or results of operations. In June 2011, the FASB issued new guidance regarding the presentation of comprehensive income. This guidance eliminates the option to present the components of other comprehensive income, or OCI, as part of the statement of stockholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income, which contains two sections, net income and OCI, or in two separate but consecutive statements. In each case, the entity is required to present reclassification adjustments on the face of the financial statements for items that are reclassified from OCI to net income in the statement where those components are presented. The amendments do not change the items that must be reported in OCI or when an item of OCI must be reclassified to net income. This new guidance is effective for interim and annual periods beginning after December 15, 2011. In October 2011, the FASB announced it would defer the effective date of the requirement to present reclassifications from OCI to net income on the face of the financial statements. However, it did not change the requirement to present net income, components of OCI, and total comprehensive income in either one continuous statement or two separate consecutive statements. The Company elected to early adopt this new guidance effective for the year ended December 31, 2011 and has presented components of OCI in two consecutive statements. The Company does not believe the adoption of the remainder of this guidance will have a material impact on its consolidated financial statements. Management does not expect other accounting standards that have been issued by the FASB or other standards-setting bodies to have a material impact on the Company’s financial position, results of operations or cash flows. |
