Adjustment to additional paid in capital resulting from the recognition of convertible debt instruments as two separate components - a debt component and an equity component. This bifurcation may result in a basis difference associated with the liability component that represents a temporary difference for purposes of applying accounting for income taxes.

| 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 or commencing shipyard modifications to meet customer requirements. 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:
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 expenditures (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 $1.4 million, $9.5 million and $9.7 million during 2012, 2011 and 2010, respectively, associated with the mobilization and pre-positioning of vessels to or from different geographic 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, 2012, 2011 or 2010. 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 the relative age of customer balances, 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. No triggering events occurred in 2012, 2011 or 2010 and the Company did not record any impairment losses related to its long-lived assets during these periods. |

| Property, Plant and Equipment | 5. Property, Plant and Equipment Property, plant and equipment consisted of the following (in thousands):
During 2012, the Company announced its 200 class OSV retrofit program. This program consists of a contract with a domestic shipyard for the upgrading and stretching of six of the Company’s Super 200 class DP-1 OSVs, converting them into 240 class DP-2 OSVs. Re-delivery of these vessels under this program is expected to occur on various dates during 2013. The project costs for these discretionary vessel modifications are expected to be approximately $50.0 million, in the aggregate ($8.3 million each). From the inception of this program through December 31, 2012, the Company had incurred approximately $2.3 million, or 4.6%, of total expected project costs. During 2011, the Company announced, and has since expanded, its fifth OSV newbuild program. On January 31, 2013, this program consisted of vessel construction contracts with two domestic shipyards to build four 300 class OSVs, six 310 class OSVs, and ten 320 class OSVs. In February 2013, the Company announced the expansion of its fifth OSV newbuild program by four vessels, as well as its intentions to ultimately build up to eight Jones Act-qualified MPSVs as a subset of its growing OSV newbuild program. We are currently negotiating with shipyards regarding these new vessels and how these new vessels will impact our outstanding contractual options. The first two vessel commitments will be reconfigured as a new class of Jones Act-qualified MPSVs based upon the HOSMAX 310 vessel design, with expected deliveries in 2015. The Company is currently evaluating various alternatives, for the remaining two vessels announced in February, and is in the process of finalizing its plans to either exercise its next two options to build additional HOSMAX OSVs for delivery in 2015; or (in lieu of building those vessels) construct one or more additional new Jones Act-qualified MPSVs. Assuming the Company opts to build two additional HOSMAX OSVs and two MPSVs, the aggregate incremental cost of the four vessels announced in February 2013 will be approximately $260.0 million (roughly $85.0 million per MPSV and $45.0 million per OSV) before construction period interest. Delivery of the first 24 vessels to be constructed under this program is expected to occur on various dates during 2013 through 2015. The aggregate cost of the Company’s fifth OSV newbuild program, excluding construction period interest, is expected to be approximately $1,160.0 million. From the inception of this program through December 31, 2012, the Company has incurred $274.6 million, or 23.7%, of total expected project costs. |

| Long-Term Debt | 6. Long-Term Debt 6.125% 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 2014 senior notes, governed by an indenture, or the 2004 indenture. The effective interest rate on the 2014 senior notes was 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 2014 senior notes and additional notes, collectively, the 2014 senior notes, had a maturity date of December 1, 2014 and required 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 were 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 were entitled to the benefits of the same 2004 indenture. On March 2, 2012, the Company commenced a cash tender offer for all of the outstanding $300.0 million aggregate principal amount of its 2014 senior notes. Senior notes totaling approximately $252.2 million, or approximately 84% of the 2014 senior notes outstanding, were validly tendered during the designated tender period and were repurchased on March 16, 2012. The remaining $47.8 million of 2014 senior notes were redeemed at 101.021% of par on April 30, 2012. A loss on early extinguishment of debt for the 2014 senior notes of approximately $5.2 million was recorded during the first quarter of 2012, which included the tender offer costs, an allocable portion of the write-off of unamortized financing costs and original issue discount, and a bond redemption premium. A loss on early extinguishment of debt of $0.9 million was recorded during the second quarter of 2012 for those costs allocable to the remaining 2014 senior notes redeemed on April 30, 2012. 8.000% Senior Notes 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 transaction costs. The Company used $200.0 million of proceeds to repay debt then-outstanding under its revolving credit facility, which may be reborrowed. The remaining proceeds were available for general corporate purposes, which included partial funding of the construction of vessels under the Company’s then existing fourth OSV newbuild program and MPSV program. 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. 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. 5.875% Senior Notes On March 2, 2012, the Company issued $375.0 million in aggregate principal amount of 5.875% senior notes due 2020, or 2020 senior notes. The net proceeds to the Company from the offering were approximately $367.4 million, net of transaction costs. The Company used $259.9 million of proceeds on March 16, 2012 to repurchase approximately 84% of the outstanding 2014 senior notes pursuant to its tender offer noted above under “6.125% senior notes.” The Company used $49.5 million of proceeds on April 30, 2012 to redeem the remaining 16% of the outstanding 2014 senior notes pursuant to the redemption noted above under “6.125% senior notes.” The remaining proceeds are available for general corporate purposes, which may include funding for the acquisition, construction or retrofit of vessels. The 2020 senior notes mature on April 1, 2020 and require semi-annual interest payments at an annual rate of 5.875%, or $11.0 million semi-annually, on April 1 and October 1 of each year until maturity. The effective interest rate on the 2020 senior notes is 6.08%. No principal payments are due until maturity. Pursuant to a registered exchange offer, the 2020 senior notes issued in March 2012 that were initially sold pursuant to private placements were exchanged by the holders for 2020 senior notes with substantially the same terms, except that the issuance of the 2020 senior notes in the exchange offer was registered under the Securities Act. The original 2020 senior notes and the similar notes exchanged were issued under and are entitled to the benefits of the same 2012 indenture. The 2017 senior notes and 2020 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 2017 senior notes and the 2020 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 2017 senior notes and the 2020 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 2017 senior notes or 2020 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. 1.625% 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 2026 convertible senior 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 2026 convertible senior notes by the holders thereof. The 2026 convertible senior 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 2026 convertible senior 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, 2012, the Company’s closing share price was $34.34.
If, upon the occurrence of certain events, the holders of the 2026 convertible senior notes exercise the conversion provisions of the 2026 convertible senior notes, the Company may need to remit the principal balance of the 2026 convertible senior notes to them in cash as discussed below. In such case, the Company would classify the entire amount of the outstanding 2026 convertible senior notes as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the 2026 convertible senior 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 2026 convertible senior note, or (ii) the conversion value, determined in the manner set forth in the indenture governing the 2026 convertible senior notes, of a number of shares equal to the conversion rate. If the conversion value exceeds the principal amount of the 2026 convertible senior 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 2026 convertible senior notes. In connection with the sale of the 2026 convertible senior 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 2026 convertible senior note hedge transactions involves the purchase of call options with exercise prices equal to the conversion price of the 2026 convertible senior notes, and are intended to mitigate dilution to the Company’s stockholders upon the potential future conversion of the 2026 convertible senior notes. Under the 2026 convertible senior 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 2026 convertible senior notes with respect to the conversion. The 2026 convertible senior note hedge transactions cover approximately the same number of shares of the Company’s common stock underlying the 2026 convertible senior 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 2026 convertible senior note hedge transactions expire at the close of trading on November 15, 2013, which is the date that the 2026 convertible senior notes are first putable by the 2026 convertible senior noteholders, although the counterparties will have ongoing obligations with respect to the 2026 convertible senior 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 2026 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 2026 convertible senior 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 2026 convertible senior 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 2026 convertible senior notes. For income tax reporting purposes, the Company has elected to integrate the 2026 convertible senior notes and the 2026 convertible senior note hedge transactions. Integration of the 2026 convertible senior note hedge with the 2026 convertible senior notes creates an in-substance original issue debt discount for income tax reporting purposes and, therefore, the cost of the 2026 convertible senior note hedge is accounted for as interest expense over the term of the 2026 convertible senior 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. 1.500% Convertible Senior Notes On August 13, 2012, the Company issued $300.0 million of convertible senior notes due 2019, or the 2019 convertible senior notes, to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2019 convertible senior notes bear interest at a fixed rate of 1.500% per annum, or $2.3 million semi-annually, which started accruing from August 13, 2012, and are payable semi-annually on March 1 and September 1 of each year, with the first interest payment on March 1, 2013. The 2019 convertible senior notes mature on September 1, 2019. Because the 2019 convertible senior notes are considered to be cash convertible debt, the Company has separately accounted for the liability and equity components of the 2019 convertible senior notes by allocating the $300.0 million in proceeds from the issuance between the liability component and the embedded conversion option, or the equity component. The allocation was conducted by estimating an interest rate at the time of issuance of the 2019 convertible senior notes for similar debt instruments that do not include the embedded conversion feature. A non-convertible interest rate of 5.75% was used to compute the initial fair value of the liability component of $227.6 million. For purposes of the fair value measurement, the Company determined that the valuation of the 2019 convertible senior notes falls under Level 2 of the fair value hierarchy. The excess of the $300.0 million of proceeds from the issuance of the 2019 convertible senior notes over the $227.6 million initial amount allocated to the liability component, or $72.4 million, was allocated to the embedded conversion option, or equity component. This excess was treated as a debt discount and is being amortized through interest expense, using the effective interest method, over the seven-year term of the 2019 convertible senior notes, which runs through September 1, 2019. The effective interest rate for these notes is 6.23%. The initial conversion rate of the 2019 convertible senior notes is 18.5718 shares per $1,000 principal amount of notes, which corresponds to a conversion price of approximately $53.85 per share. The conversion rate was based on the last reported sale price of the Company’s common shares on The New York Stock Exchange of $39.16 on August 7, 2012. The conversion rate will be subject to adjustment in some events but will not be adjusted for accrued interest. In addition, following certain corporate transactions that constitute “fundamental changes” (as defined in the indenture for the 2019 convertible senior notes), the conversion rate will be increased for holders who elect to convert notes in connection with such corporate transactions in certain circumstances. The 2019 convertible senior notes are convertible based on the applicable conversion rate only under the following circumstances:
Upon conversion, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election. If the holders of the 2019 convertible senior notes exercise the conversion provisions of the 2019 convertible senior notes and the Company elects to settle such conversions partially in cash (which it presently intends to do at least up to the principal amount of the notes), the Company will need to remit such cash amount to the converting holders. For that reason, in any period during which the 2019 convertible senior notes are convertible as provided above, the Company would classify the entire principal amount of the outstanding 2019 convertible senior notes as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the 2019 convertible senior notes will occur every calendar quarter. The 2019 convertible senior notes are not redeemable at the option of the Company prior to their maturity. No sinking fund is provided for the 2019 convertible senior notes and the 2019 convertible senior notes are not subject to legal defeasance.
If the Company experiences specified types of corporate transactions, including certain change of control events or a de-listing of the Company’s common stock, holders of the 2019 convertible senior notes may require the Company to purchase all or a portion of their 2019 convertible senior notes. Any repurchase of the convertible senior notes pursuant to these provisions will be for cash at a price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the purchase date. In connection with the sale of the 2019 convertible senior notes, the Company entered into convertible senior note hedge transactions with respect to its common stock with affiliates of the initial purchasers of the notes, Barclays, Inc., JP Morgan Chase and Wells Fargo Bank, or the counterparties. Each of the 2019 convertible senior note hedge transactions is a privately-negotiated transaction that is economically equivalent to the purchase of call options on the Company’s common stock with strike prices equal to the conversion price of the 2019 convertible senior notes, and is intended to mitigate dilution to the Company’s stockholders and/or offset cash payment due upon the potential future conversion of the 2019 convertible senior notes. Under the 2019 convertible senior note hedge transactions, subject to customary anti-dilution provisions, the counterparties are required to deliver to the Company the approximate number of shares of the Company’s common stock and/or an amount of cash that the Company is obligated to deliver to the holders of the 2019 convertible senior notes assuming the conversion of such notes. The Company also entered into separate privately-negotiated warrant transactions, whereby the Company sold to each of the counterparties call options to acquire approximately the same number of shares of its common stock underlying the convertible senior note hedge transactions, subject to customary anti-dilution adjustments, at a strike price of $68.53 per share of common stock, which represented a 75.0% premium over the closing price of the Company’s shares of common stock on August 7, 2012. Upon the exercise of the warrants, if the market price of the common stock exceeds the strike price of the warrants on any day within the valuation period, the Company will be required to deliver the corresponding value to the counterparties, at its option in cash or shares of its common stock. The 2019 convertible senior 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 2019 convertible senior notes. For income tax reporting purposes, the Company has elected to integrate the 2019 convertible senior notes and the note hedge transactions. Integration of the 2019 convertible senior note hedge with the 2019 convertible senior notes creates an in-substance original issue debt discount for income tax reporting purposes and, therefore, the cost of the 2019 convertible senior note hedge is accounted for as interest expense over the term of the 2019 convertible senior 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.
The Company used a portion of the $290.8 million in net proceeds of the 2019 convertible senior notes offering, along with a portion of the $48.2 million in proceeds from the sale of warrants, to fund the $73.0 million cost of convertible senior note hedge transactions. The Company intends to use the remaining net proceeds of approximately $266.0 million from the sale of the 2019 convertible senior notes and the sale of the warrants, along with other available sources of cash, to retire its 2026 convertible senior notes, which are first subject to repurchase by the Company at the option of holders of such 2026 convertible senior notes, on November 15, 2013, and subject to redemption at the Company’s option on or after November 15, 2013, in each case at par plus accrued and unpaid interest, or for general corporate purposes, which may include retirement of other debt or funding for the acquisition, construction or retrofit of vessels. The Company expects to retire its 2026 convertible notes on or promptly after November 15, 2013 in full with cash on-hand today. The Company incurred $9.3 million of fees and other costs related to the issuance of the 2019 convertible senior notes. These fees and other origination costs have been allocated to the liability and equity components of the 2019 convertible senior notes in proportion to their allocated values. Approximately $2.2 million of these fees and other origination costs were recorded as a reduction in additional paid-in capital. The remaining $7.1 million of fees and other costs are being amortized as interest expense over the seven-year term of the 2019 convertible senior notes, which runs through September 1, 2019. The 2019 convertible senior notes and the 2026 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 the Securities and Exchange Commission, or Commission, regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the 2019 convertible senior notes and the 2026 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 2019 convertible senior notes and the 2026 convertible senior 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 2017 senior notes, and its 2020 senior notes. 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, 2012, 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, 2012, 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 2017 senior notes and 2020 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 2017 senior notes, 2020 senior notes, 2019 convertible senior notes and 2026 convertible senior notes by primarily 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 $1,175.0 million, $1,089.4 million and $1,210.1 million, respectively, as of December 31, 2012. Given the observable nature of the inputs to these estimates, the fair values presented for long-term debt have been assigned a Level 2, of the three-level valuation hierarchy. Interest expense excludes capitalized interest related to the construction or conversion of vessels in the approximate amount of $11.0 million, $0.4 million, and $3.7 million, for the years ended December 31, 2012, 2011, and 2010, 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.

| 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. As of December 31, 2012, there were 708,936 shares available for future issuance to employees under the incentive compensation plan. 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 financial impact of stock-based compensation expense related to the Company’s incentive compensation plan on its operating results are reflected in the table below (in thousands, except for per share data):
For the years ended December 31, 2012 and 2010, approximately $0.1 million and $0.4 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 $0.9 million, $0.4 million, and $0.4 million for the years ended December 31, 2012, 2011, and 2010, respectively. Net cash proceeds from the exercise of stock options were $1.8 million, $0.6 million, and $0.6 million for the years ended December 31, 2012, 2011, and 2010, respectively. The income tax benefit from stock option exercises and restricted stock vesting was $3.0 million, $2.0 million, and $2.7 million for the respective periods. As of December 31, 2012, the Company has approximately 0.7 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 to any employees during 2012 or 2010.
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, 2012 (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, 2012 (in thousands, except per share data):
As of December 31, 2012, the Company had unamortized stock-based compensation expense of $0.9 million that will be recognized on a straight-line basis over the remaining vesting period, or 1.0 year, and has recorded approximately $0.8 million of compensation expense during 2012, associated with stock options. Restricted Stock Equity-Settled 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 that may differ from year to year, including such examples as the Company achieving a targeted return on invested capital, return on equity, Upstream operating profit margin, safety record 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 and/or extent of performance goals attained by the Company. This type of performance-based restricted stock unit was granted in 2012. 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 awards, which is amortized over a one to three-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, 2012, the Company had unamortized stock-based compensation expense of $7.2 million, which will be recognized on a straight-line basis over the remaining vesting period, or 1.4 years. In addition, the Company has recorded approximately $8.5 million of compensation expense during the year ended December 31, 2012 associated with restricted stock-based unit awards. The following table summarizes the restricted stock awards activity during the year ended December 31, 2012 (in thousands, except per share data):
Cash-Settled Restricted Stock The Company’s incentive compensation plan allows the Company to issue restricted stock units with cash-settled vesting provisions. The compensation expense related to cash-settled phantom restricted stock awards is amortized over a vesting period of up to three years, as applicable, and 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. The cash-settled phantom restricted stock units are re-measured quarterly and classified as a liability, due to the settlement of these awards in cash. This type of phantom time-based restricted stock unit was granted in 2012. As of December 31, 2012, the Company had unamortized cash-settled phantom compensation expense of $3.3 million, which will be recognized on a straight-line basis over the remaining vesting period, or 2.0 years. In addition, the Company has recorded approximately $1.3 million of compensation expense during the year ended December 31, 2012 associated with cash-settled phantom awards. The following table summarizes the phantom cash-settled restricted stock awards activity during the year ended December 31, 2012 (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, 2012, there were 272,903 shares available for future issuance to employees under the ESPP. The Company has recorded approximately $0.7 million of compensation expense during the year ended December 31, 2012 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, 2012 and 2011:

| Commitments and Contingencies | 10. Commitments and Contingencies Operating Leases The Company is obligated under certain operating leases for office space, shore-base facilities and vehicles. The Covington facility lease, which is a new lease that commenced on July 1, 2012, provides for an initial term expiring in September 2025 with three additional five-year renewal period options. 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, 2012, this latter facility lease had approximately two years remaining on its initial term, with four additional five-year renewal periods. Rent expense related to operating leases was approximately $3.2 million, $2.3 million and $2.1 million for the years ending December 31, 2012, 2011 and 2010, respectively. Future minimum payments under noncancelable leases for years subsequent to 2012 are as follows (in thousands):
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 2012 and 2011, 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, 2012, the Company’s claims incurred under its P&I Club policies have not exceeded the AAD for the 2012 or 2011 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, 2012. 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 a material impact on its interim or annual results of operations. During 2012, an Upstream customer, ATP Oil and Gas, Inc., initiated a reorganization proceeding under Chapter 11 of the United States Bankruptcy Code. Pre-petition receivables from ATP were $4.8 million and the Company has recorded $0.9 million in reserves. While the Company believes that the net receivables are collectible, it will continue to monitor the proceedings, which may result in actual collections that may differ from the current estimate. |

| 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 or commencing shipyard modifications to meet customer requirements. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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:
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 expenditures (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 $1.4 million, $9.5 million and $9.7 million during 2012, 2011 and 2010, respectively, associated with the mobilization and pre-positioning of vessels to or from different geographic 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, 2012, 2011 or 2010. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentration of Credit Risk | 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 the relative age of customer balances, 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. No triggering events occurred in 2012, 2011 or 2010 and the Company did not record any impairment losses related to its long-lived assets during these periods. |

Tabular disclosure of the extent of the entity's reliance on its major customers, if revenues from transactions with a single external customer amount to 10 percent or more of entity revenues, including the disclosure of that fact, the total amount of revenues from each such customer, and the identity of the reportable segment or segments reporting the revenues. The entity need not disclose the identity of a major customer or the amount of revenues that each segment reports from that customer. For these purposes, a group of companies known to the entity to be under common control is considered a single customer, and the federal government, a state government, a local government such as a county or municipality, or a foreign government is each considered a single customer.
