ASC 842, Leases Lessor Accounting In July 2018, the Financial Accounting Standards Board, or FASB, issued ASU 2018-11 that allows for 1) a transition option that will allow companies to not apply the new lease standard in the comparative periods presented in their financial statements in the year of adoption and will allow the Company to continue to apply legacy guidance, ASC 840 Leases, including its disclosure requirements, for comparative periods presented, and 2) an option for lessors to combine lease and non-lease components contained within the same agreement when certain criteria are met. The Company does not expect a change in the timing or amounts of revenues recognized upon the adoption of this standard. Lessee Accounting The primary difference between current accounting standards and ASC 842 is the recognition of right-of-use assets and corresponding liabilities by lessees for those leases classified as operating leases under current accounting standards. The estimated impact of the adoption of this ASC based on the lease arrangements for which the Company is the lessee as of June 30, 2018, will be an increase to assets and liabilities on the Company's financial statements to reflect the right-of-use assets and lease obligations in a range from $27.0 million to $30.0 million. The adoption of the new standard is not expected to result in a change in the amount of lease expense currently being recognized. |

| Revenue from Contract with Customer [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue from Contract with Customer | Revenues from Contracts with Customers Effective January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers using the modified retrospective method. The adoption of this standard did not have a material impact on the Company's financial position or results of operations. Accordingly, the Company did not make an adjustment to the opening balance of retained earnings in order to account for the implementation of the new requirements of this standard, and it did not restate prior period information for the effects of the new standard. The services that are provided by the Company represent a single performance obligation under our contracts that are satisfied at a point in time or over time. Revenues are earned primarily by (1) chartering the Company's vessels, including operation of such vessels, (2) providing vessel management services to third party vessel owners, and (3) providing shore-based port facility services, including rental of land. These revenue streams are provided to customers based upon contracts that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The Company's vessel revenues, vessel management revenues and port facility revenues are recognized either at a point in time or over the passage of time when the customer has received or is receiving the benefit from the applicable service. Revenues are recognized when the performance obligations are satisfied in accordance with contractual terms and in an amount that reflects the consideration that the Company expects to be entitled to in exchange for the services rendered or rentals provided. Revenues are recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Invoices are typically billed to our customers on a monthly basis and payment terms on customer invoices typically range 30 to 60 days. A performance obligation under contracts with the Company's customers to render services is the unit of account under Topic 606. The Company accounts for services rendered separately if they are distinct and the service is separately identifiable from other items provided to a customer and if a customer can benefit from the services rendered provided on its own or with other resources that are readily available to the customer. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. As of June 30, 2018, the Company has certain remaining performance obligations representing contracted vessel revenues for which work has not been performed and such contracts have an original expected duration of more than one year. As of June 30, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations for such contracts was $16.4 million, of which $15.8 million and $0.6 million are expected to be recognized in 2018 and 2019, respectively. The Company has elected to apply the optional exemption for the disclosure of the remaining performance obligations for any of its revenue streams that are expected to have a duration of one year or less and, therefore, such amounts have not been disclosed. Disaggregation of Revenues For the three and six months ended June 30, 2018 and 2017, the Company recognized revenues as follows (in thousands):

| Earnings (Loss) Per Share | Loss Per Share Basic loss per common share was calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per common share was calculated by dividing net loss by the weighted average number of common shares outstanding during the year plus the effect of dilutive stock options and restricted stock unit awards. When reporting a net loss, the Company uses weighted average basic shares outstanding to calculate diluted earnings per share. Weighted average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period. The table below reconciles the Company’s loss per share (in thousands, except for per share data):

| Property, Plant and Equipment [Abstract] | |
| Property, Plant and Equipment | Property, Plant and Equipment Asset Impairment Assessment In accordance with ASC 360, the Company periodically reviews long-lived asset valuations when events or changes in circumstances indicate that an asset’s carrying value may not be recoverable. If indicators of impairment exist, the Company assesses the recoverability of its long-lived assets by comparing the projected future undiscounted cash flows associated with the related long-lived asset group over their remaining estimated useful lives. If the sum of the estimated undiscounted cash flows are less than the carrying amounts of the asset group, the assets are written down to their estimated fair values based on the expected discounted future cash flows or appraised values attributable to the assets. The future cash flows are subjective and are based on the Company’s current assumptions regarding future dayrates, utilization, operating expense, G&A expense and recertification costs that could differ from actual results. During the second quarter of 2016, the Company determined that it observed indicators of impairment related to its vessels. This resulted from the rapid deterioration of its second quarter 2016 operating results, as well as the uncertainty regarding future market conditions and the related impact on the Company's projected operating results. For the purposes of calculating the undiscounted cash flows, the Company grouped its vessels into two groups, OSVs and MPSVs, and used a probability-weighted undiscounted cash flow projection to test for recoverability. After reviewing the results of this calculation, the Company determined that each of its asset groups had sufficient projected undiscounted cash flows to recover the remaining book value of the Company's long-lived assets within such groups. While the Company has not observed any new impairment indicators since the second quarter of 2016, the Company has reviewed and updated, as necessary, the assumptions used in determining its undiscounted cash flow projections for each asset group to reflect current market conditions. After reviewing the results of these updated projections, the Company determined that each of its asset groups continue to have sufficient projected undiscounted cash flows to recover the remaining book value of the Company's long-lived assets within such group. |

First-Lien Credit Facility The Company's $300 million first-lien credit facility, or Credit Facility, matures in June 2023 and currently provides for $136.7 million of additional available liquidity, $68.0 million of which is required to be drawn by December 31, 2018 with the remaining balance required to be drawn by September 1, 2019. The Company can use draws under the facility for working capital and general corporate purposes, including the acquisition of distressed assets and/or the refinancing of existing debt, subject to, among other things, compliance with certain covenants requiring the Company to maintain access to liquidity (cash and credit availability) of $25.0 million at all times. The minimum liquidity level required for prepayment of the Company’s existing indebtedness and/or certain other restricted payments is $65.0 million. The Credit Facility is collateralized by 55 domestic high-spec OSVs and MPSVs, including a security interest in two pending MPSV newbuilds, and associated personalty, as well as by certain deposit and securities accounts. Borrowings accrue interest, at the Company’s option, at either an adjusted London Interbank Offered Rate (subject to a 1.00% floor) plus an applicable margin or the greatest of (a) the prime rate announced by The Wall Street Journal, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%, and (c) the London Interbank Offered Rate plus, 1%, plus, an applicable a margin. On March 27, 2018, the Company entered into an amendment with its first-lien lenders to clarify various provisions in and made certain technical revisions to the Credit Facility, primarily dealing with the administerial permissabilities regarding vessel reflagging transactions and permitted acquisition indebtedness, among other matters. The agreement governing the Credit Facility and the indentures governing the Company's 2020 senior notes and 2021 senior notes impose certain 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 2020 senior notes, 2021 senior notes, 2019 convertible senior notes and Credit Facility by primarily using quoted market prices. Given the observability of the inputs to these estimates, the Company has assigned a Level 2 of the three-level valuation hierarchy for such outstanding notes. As of the dates indicated below, the Company had the following face values, carrying values and fair values (in thousands):
Capitalized Interest During the three months ended June 30, 2018, the Company did not capitalize any of its interest costs. During the six months ended June 30, 2018, the Company capitalized approximately $2.3 million of interest costs related to the construction of vessels. During the three and six months ended June 30, 2017, the Company capitalized approximately $2.5 million and $4.9 million, respectively, of interest costs related to the construction of vessels. |

| Incentive Compensation | Incentive Compensation Stock-Based Incentive Compensation Plan The Company’s stock-based incentive compensation plan covers a maximum of 4.95 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options, stock appreciation rights and fully-vested common stock to employees and directors. As of June 30, 2018, the Company has granted awards covering 4.68 million shares of common stock under such plan. During the six months ended June 30, 2018, the Company granted 1,527,102 time-based and 939,391 performance-based phantom restricted stock units. The phantom shares to be received under the performance-based phantom restricted stock units are calculated based on the Company's performance compared to two pre-determined criteria, as defined by the phantom restricted stock unit agreements governing such awards. The actual number of shares that could be received by the award recipients can range from 0% to 150% of the awards granted depending on the Company's performance. The fair value of the Company’s performance-based phantom restricted stock units, which is the stock price on the date of grant, is applied to the total shares that are expected to fully vest and is amortized over the vesting period, which is generally three years, based on the Company’s internal performance measured against the pre-determined criteria, as applicable. The compensation expense related to time-based phantom restricted stock units are 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. All phantom restricted stock units are re-measured quarterly and classified as a liability, due to the settlement of these awards in cash. In addition to the phantom restricted stock units granted in 2018, the Company granted performance-based and time-based restricted stock units and phantom restricted stock units in prior years. During the six months ended June 30, 2018, the Company issued 426,896 shares of common stock due to vestings of restricted stock units and employee purchases under the Company's Employee Stock Purchase Plan.

| Commitments and Contingencies | Commitments and Contingencies Vessel Construction During the first quarter of 2018, the Company notified the shipyard that it was terminating the construction contracts for the final two vessels in the Company's fifth OSV newbuild program due to performance issues at the shipyard. The Company is working with the issuer of the shipyard's performance bonds in order to complete the construction of the vessels at a completion yard. The cost of this nearly completed 24-vessel newbuild program, before construction period interest, is expected to be approximately $1,335.0 million, of which $17.0 million, and $44.8 million are currently expected to be incurred in the remainder of 2018 and fiscal 2019, respectively. However, the timing of these remaining construction draws remains subject to change commensurate with any potential further delays in the delivery dates of the final two newbuild vessels. From the inception of this program through June 30, 2018, the Company had incurred $1,273.2 million, or 95.4%, of total expected project costs. Vessel Acquisitions On May 18, 2018, the Company completed the acquisition of four high-spec Jones Act-qualified OSVs and related equipment from Aries Marine Corporation and certain of its affiliates for $40.9 million in cash, inclusive of $4.0 million related to a non-compete intangible asset that will be amortized over the life of such asset, or two years. Also included in this transaction was the cost of fuel and lube inventory and transactions fees. The acquired vessels are all U.S.-flagged and are comprised of two 300 class OSVs and two 280 class OSVs. The Company determined that substantially all of the fair value of the assets acquired are concentrated in a group of similar identifiable assets and, therefore, has accounted for such transaction as an asset acquisition under ASU 2017-01. 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 the Company's 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. The Company provides reserves for 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. |

| Income Tax Disclosure [Abstract] | |
| Income Tax Disclosure | Income Taxes The Tax Cuts and Jobs Act, or the Act, was signed into law on December 22, 2017. The primary impact of this legislation was a reduction of the U.S. federal corporate tax rate from 35% to 21% generally effective January 1, 2018. As of December 31, 2017, the Company included in its income tax benefit rate a preliminary estimate related to executive compensation, alternative minimum tax refundable credits, taxation in its foreign jurisdictions, and re-measurement of its deferred taxes. As of June 30, 2018, the Company has not identified or recorded any revisions to its provisional amounts and has not completed its accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, the Company made reasonable estimates of the effects and recorded provisional amounts. The Company's provisional estimates on Global Intangible Low Taxed Income, Foreign Derived Intangible Income, Base Erosion and Anti-Abuse, and the IRC Section 163(j) interest limitation did not materially impact its effective tax benefit rate for the three months ended June 30, 2018. The Company will continue to refine its calculations as additional tax guidance becomes available and its internal analysis is completed. The accounting for the tax effects of the Act will be completed in 2018 as allowed under Staff Accounting Bulletin 118, which was issued by the Securities and Exchange Commission on December 22, 2017. The effective tax benefit rate for the six months ended June 30, 2018 and 2017 was 19.0% and 31.3%, respectively. The lower benefit rate for the quarter ended June 30, 2018 was primarily due to the reduction of the statutory corporate income tax rate from 35% to 21% resulting from the Act. In addition, the Company established valuation allowances in 2017 for foreign tax credit carryforwards based upon management's conclusion that it is more likely than not such losses and credits will not be realized by their expiration dates. |
