Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Deep Down, Inc. and its directly and indirectly wholly-owned subsidiaries (“Deep Down,” “we,” “us” or the “Company”) were prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC” or the “Commission”) pertaining to interim financial information and instructions to Form 10-Q. As permitted under those rules, certain footnotes or other financial information that are normally required by United States generally accepted accounting principles (“US GAAP”) can be condensed or omitted. Therefore, these statements should be read in conjunction with the audited consolidated financial statements, and footnotes thereto, included in our Annual Report on Form 10-K for the year ended December 31, 2015, filed on March 29, 2016 with the Commission. Preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosed amounts of contingent assets and liabilities and the reported amounts of revenues and expenses. If the underlying estimates and assumptions upon which the financial statements are based change in future periods, then the actual amounts may differ from those included in the accompanying unaudited condensed consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Certain previously reported amounts have been reclassified to conform to current period presentation.

Segments	Segments We operate one principal deepwater oilfield services business, which provides many solutions to our customers. For the three months ended March 31, 2016 and 2015, we only had one reporting segment, Deep Down Delaware. All of the services and products we provide are interrelated, performed for the same general customers and marketed as such. In accordance with ASC Topic 280, Segment Reporting, operating segments are defined as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”) in deciding how to allocate resources and in assessing performance. Our CODM primarily evaluates performance based on each project’s gross margin and net income. In determining the reportable segment, we concluded that all services and products have similar economic and other characteristics, including similar gross margin percentage, production processes, suppliers, regulatory environments, customer type, and underlying demand and supply. Our services and products follow the same accounting policies and are managed by our management team.
Recently Issued Adopted Accounting Standards	Recently Issued Accounting Standards Not Yet Adopted In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 provides guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendments in ASU 2014-15 are effective for annual reporting periods ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. The Company will adopt the methodologies prescribed by ASU 2014-15 by the date required, and does not anticipate that the adoption of ASU 2014-15 will have a material effect on its financial position or results of operations. In May 2014, the FASB issued a new standard on revenue recognition that supersedes previously issued revenue recognition guidance. This standard provides a five-step approach to be applied to all contracts with customers and requires expanded disclosures about the nature, amount, timing and uncertainty of revenue (and the related cash flows) arising from customer contracts, significant judgments and changes in judgments used in applying the revenue model and the assets recognized from costs incurred to obtain or fulfill a contract. The effective date for this standard was deferred in July 2015 and will now be effective for us beginning in 2018. The standard permits the use of either the retrospective or cumulative effect transition method; therefore we are evaluating the effect that this new guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this update require, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The amendments are effective for interim and annual reporting periods beginning after December 15, 2018. We are currently evaluating the impacts of the amendments to our financial statements and accounting practices for leases.
