Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Rowan Companies plc, a public limited company incorporated under the laws of England and Wales, is a leading offshore drilling contractor for the oil and gas industry. Our fleet currently consists of 32 mobile offshore drilling units, including 28 self-elevating jack-up drilling units and four ultra-deepwater drillships. We contract our drilling rigs, related equipment and work crews primarily on a day rate basis in markets throughout the world, currently in the U.S. Gulf of Mexico (US GOM), the United Kingdom (U.K.) and Norwegian sectors of the North Sea, the Middle East, North Africa, Southeast Asia and Trinidad. The financial statements included in this Form 10-Q are presented in United States (U.S.) dollars and include the accounts of Rowan Companies plc ( “ Rowan plc ” ) and its subsidiaries. Unless the context otherwise requires, the terms “Company,” “we,” “us” and “our” are used to refer to Rowan plc and its consolidated subsidiaries. Intercompany balances and transactions are eliminated in consolidation. The financial statements included in this Form 10-Q have been prepared without audit in accordance with accounting principles generally accepted in the United States of America (US GAAP) for interim financial information and the applicable rules and regulations of the U.S. Securities and Exchange Commission (SEC). Certain information and notes have been condensed or omitted as permitted by those rules and regulations. Management believes the accompanying financial statements contain all adjustments, which are of a normal recurring nature unless otherwise noted, necessary for a fair statement of the results for the interim periods presented. The Company’s results of operations and cash flows for the interim periods are not necessarily indicative of results to be expected for the full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 . New Accounting Standards – In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which sets forth a global standard for revenue recognition and replaces most existing industry-specific guidance. We will be required to adopt the new standard in annual and interim periods beginning January 1, 2018. We are currently evaluating the potential effect of the new standard. In February 2015, the FASB issued ASU No. 2015-02, Amendments to the Consolidation Analysis, which changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. We will be required to adopt the new standard in annual and interim periods beginning January 1, 2016. We do not expect adoption of the new standard will have a material effect on our financial statements. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in financial statements. Under this ASU, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. Debt issuance costs incurred before the associated funding is received (i.e., the debt liability) should be reported on the balance sheet as deferred charges until the debt is recognized on the balance sheet. We will be required to adopt the new standard in annual and interim periods retrospectively beginning January 1, 2016. We do not expect adoption of the new standard will have a material effect on our financial statements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Uncertain tax positions – In 2009, the Company recognized certain tax benefits as a result of applying the facts of a third-party tax case to the Company’s situation. That case provided a more favorable tax treatment for certain foreign contracts entered into in prior years. Our position was challenged by the U.S. Internal Revenue Service. We appealed their findings and reached a settlement agreement in September 2014 with respect to three of the four years under review in the amount of approximately $36 million , including interest, which we collected in October 2014. A remaining year continues to be under examination. We plan to vigorously defend our position. Other matters – On March 22, 2015, while working for Cobalt International Energy, Inc. (“Cobalt”) in the Gulf of Mexico, the Rowan Reliance drillship experienced a loss of seal in the riser connection system which resulted in a spill of approximately 2,200 barrels of synthetic-oil based mud. The well was plugged and abandoned on April 6, 2015, and on April 22, 2015, we commenced drilling the next well under our existing contract. We are working with Cobalt toward a resolution and we expect to receive and have recognized revenue reflecting our anticipated outcome. We do not expect resolution of the matter will have a material impact on the financial statements. On April 21, 2015 the Bureau of Safety and Environmental Enforcement (BSEE) informed the Company it will conduct a Quality Control - Failure Incident Team (QC-FIT) evaluation of the incident, and the Company is cooperating with BSEE in the evaluation. In November 2013, one of our subsidiaries hired HS Ocean Group Ltd. (“HSOG”) to perform rig refurbishment work on the Rowan Gorilla III in La Brea, Trinidad, under a lump-sum contract valued at about $20 million . On April 24, 2014, the subsidiary terminated the contract with HSOG for default and alternatively for convenience as provided for under the contract. At the time of the termination, the subsidiary had paid HSOG approximately $10.9 million in milestone payments. On May 23, 2014, HSOG commenced arbitration in London in accordance with the terms of the contract. HSOG has asserted claims now totaling approximately $25 million , exclusive of interest and legal costs, net of the sums paid by the subsidiary. The Company has previously recognized an estimated liability, including an incremental adjustment in the amount of $5.0 million recognized in the quarter ended June 30, 2015. Although the outcome of this matter cannot be predicted with certainty, we do not believe its resolution will have a material impact on our financial statements. Letters of credit – We periodically employ letters of credit in the normal course of our business, and had outstanding letters of credit of approximately $11.9 million at June 30, 2015 . We are involved in various other legal proceedings incidental to our business and are vigorously defending our position in all such matters. Although the outcome of such proceedings cannot be predicted with certainty, we do not expect resolution of these matters to have a material effect on our financial position, results of operations or cash flows.

Share-Based Compensation

Share-Based Compensation	Jun. 30, 2015
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation On February 26, 2015, the Company granted restricted share units (RSUs) to employees for annual incentive awards pursuant to our long-term incentive plan with a grant-date fair value aggregating $22.5 million . The awards vest ratably over three years except to the extent they may vest earlier under our retirement policy. The aggregate fair value, net of estimated forfeitures, was $21.2 million , which will be recognized as compensation expense over a weighted-average period of 2.7 years from the grant date. Each RSU awarded to employees is granted in tandem with a corresponding dividend equivalent which entitles the employee to receive an amount in cash equal to any cash dividends paid by the Company with respect to the underlying shares. Dividend equivalents are payable as and when the RSUs vest. Any dividend equivalent amounts are forfeited if the corresponding RSUs are forfeited or do not vest. The Company has been paying a regular quarterly cash dividend since May 2014. Additionally, on February 26, 2015, the Company granted to certain members of management performance units (P-Units) that have a target value of $100 per unit. The amount ultimately earned with respect to the P-Units will depend on the Company’s total shareholder return (TSR) ranking compared to a group of peer companies over a three -year period ending December 31, 2017, and could range from zero to $200 per unit depending on performance. Twenty-five percent of the P-Units’ value is determined by the Company’s relative TSR ranking for each one-year period ended December 31, 2015 , 2016 , and 2017 , respectively, and 25% of the P-Units’ value is determined by the relative TSR ranking for the three -year period ending December 31, 2017. Vesting of awards and any payment with respect to the P-Units would not occur until the third anniversary following the grant date and would be settled in cash. The grant-date fair value of the P-Units was estimated to be $9.0 million . Fair value was estimated using a Monte Carlo simulation model, which considers the probabilities of the Company’s TSR ranking at the end of each performance period and the amount of the payout at each rank to determine the probability-weighted expected payout. The Company uses liability accounting to account for the P-Units. Compensation is recognized on a straight-line basis over a maximum period of three years from the grant date and is adjusted for changes in fair value through the vesting date. Estimated liabilities for outstanding P-Units aggregated $13.0 million and $11.6 million , at June 30, 2015 , and December 31, 2014 , respectively. At June 30, 2015 , the Company had approximately $57.3 million of estimated unrecognized share-based compensation, which is expected to be recognized as compensation expense over a remaining weighted-average period of 1.9 years .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy prescribed by US GAAP requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted market prices for similar instruments in active markets; quoted prices for identical instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable, such as those used in pricing models or discounted cash flow methodologies, for example. The applicable level within the fair value hierarchy is the lowest level of any input that is significant to the fair value measurement. Assets and Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands): Estimated fair value measurements Carrying value Quoted prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant other unobservable inputs (Level 3) June 30, 2015: Assets - cash equivalents $ 187,267 $ 187,267 $ — $ — Other assets 14,594 14,594 — — December 31, 2014: Assets - cash equivalents $ 314,570 $ 314,570 $ — $ — Other assets 16,304 16,304 — — At June 30, 2015 and December 31, 2014, we held Egyptian pounds in the amount of $14.6 million and $16.3 million , respectively, which are classified as other noncurrent assets. We ceased drilling operations in Egypt in 2014, and are currently working to repatriate the funds to the extent they are not utilized in Egypt. Trade receivables and trade payables, which are required to be measured at fair value, have carrying values that approximate their fair values due to their short maturities. Other Fair Value Measurements Financial instruments not required to be measured at fair value consist of the Company’s publicly traded debt securities and draws under our revolving credit facility, which comprises our short-term bank debt. Our publicly traded debt securities are classified as long-term debt and had a carrying value of $2.807 billion at June 30, 2015 , and an estimated fair value at that date aggregating $2.694 billion , compared to a carrying and fair value of $2.807 billion and $2.755 billion , respectively, at December 31, 2014 . Fair values of our publicly traded debt securities were provided by a broker who makes a market in such securities and were measured using a market-approach valuation technique. Fair value was determined by adding a spread based on actual trades for that security (or a trader quote where actual trades were unavailable) to the applicable benchmark Treasury security with a comparable maturity in order to derive a current yield. The yield is then used to determine a price given the individual security’s coupon rate and maturity. Such inputs are considered “significant other observable inputs” which are categorized as Level 2 inputs in the fair value hierarchy. Draws under our revolving credit facility have an interest rate that resets monthly, and their fair value approximated their $50 million carrying value at June 30, 2015 .

Equity [Abstract]
Shareholders' Equity	Shareholders' Equity We maintain an affiliated employee benefit trust (EBT) to hold shares for future use to satisfy our obligations to deliver shares in connection with awards granted under our long-term incentive plans. At June 30, 2015 and December 31, 2014 , the EBT held 1,160,928 and 264,903 shares, respectively. In February 2015, pursuant to authority granted by the Board, we issued 1.1 million Class A ordinary shares, $0.125 par value per share, in a noncash transaction and immediately transferred them to the EBT. Shares held by the Company's EBT are not eligible to vote or to receive dividends and are classified as treasury shares in the condensed consolidated balance sheet. Pursuant to authority previously granted, our Board of Directors may increase our share capital through the issuance of additional shares, up to an aggregate 150,000,000 shares (at current nominal value of $0.125 per share) without obtaining further shareholder approval. This authority expires in May 2017 unless reapproved by shareholders. On January 29 and May 1, 2015, the Board of Directors approved quarterly cash dividends of $0.10 per Class A ordinary share, which were paid on March 3 and May 26, 2015, to shareholders of record at the close of business on February 9 and May 12, 2015, respectively. On July 30, 2015 , the Board of Directors approved a quarterly cash dividend of $0.10 per Class A ordinary share, payable on August 25, 2015 , to shareholders of record at the close of business on August 11, 2015 . Accumulated Other Comprehensive Loss – The following table sets forth the significant amounts reclassified out of each component of accumulated other comprehensive loss and their effect on net income for the period.

The net carrying value was $4.1 million , consisting of a $24.2 million asset previously classified as assets of discontinued operations, less $20.1 million of deferred revenues previously classified as liabilities of discontinued operations. The Company received $6.0 million in cash resulting in a $4.0 million gain, net of tax effects, which was recognized in the six months ended June 30, 2014 . Supplemental Cash Flow Information – Accrued capital expenditures, which are excluded from capital expenditures in the Condensed Consolidated Statements of Cash Flows until settlement, totaled $41.4 million and $46.6 million at June 30, 2015 and 2014 , respectively. Interest capitalized in connection with rig construction projects totaled $8.7 million and $16.2 million in the three and six months ended June 30, 2015 , as compared to $13.0 million and $30.5 million, respectively, in the comparable periods of the prior year. Income Taxes – In accordance with US GAAP for interim reporting, the Company estimates its full-year effective tax rate and applies this rate to its year-to-date pretax income. In addition, the Company separately calculates the tax impact of unusual items, if any. We provide for income taxes based upon the tax laws and rates in effect in the countries in which we conduct operations. The amounts of our provisions are impacted by such laws and rates and the availability of deductions, credits and other benefits in each of the various jurisdictions. Our overall effective tax rate may therefore vary considerably from quarter to quarter and from year to year based on the actual or projected location of operations and other factors. Our effective tax rate was 8.3% and 10.7% , respectively, for the three and six months ended June 30, 2015 , compared to 5.7% and 2.5% , respectively, for the comparable prior-year periods. The higher effective rates for the current-year periods were due to net increases to the valuation allowance on certain deferred tax assets, partially offset by additional income in low-tax jurisdictions. On July 31, 2015, we sold two of the oldest rigs in our jack-up fleet. The tax impact of these sales has not been reflected in our annual effective tax rate as these are subsequent events as of the balance sheet date. We anticipate that the sales will impact our ability to benefit the deduction of certain expenses for tax purposes and will result in an increase in the valuation allowance on our deferred tax assets of between $6 million and $9 million . The Company has not provided for deferred income taxes on undistributed earnings of its non-U.K. subsidiaries, including non-U.S. entities under Rowan Companies, Inc. (RCI), except for a portion of its Saudi Arabia operating entity's earnings that are expected to be distributed in 2015. It is the Company’s policy and intention, except as noted above, to permanently reinvest outside the U.S. the earnings of non-U.S. entities directly or indirectly owned by RCI. Generally, earnings of non-U.K. entities in which RCI does not have a direct or indirect ownership interest can be distributed to the Company without imposition of either U.K. or local country tax. In December 2014, the U.K. Treasury released a draft proposal that would impose tax on groups that use certain tax planning techniques that are perceived as diverting profits from the U.K. The Diverted Profit Tax rule was included in the 2015 Finance Bill, and on March 26, 2015, the legislation received Royal Assent with an effective date of April 1, 2015. We do not believe the legislation will have a material impact on our financial statements. Litigation Settlement – In the first quarter of 2014, we settled our litigation with the owners and operators of a tanker that collided with the Rowan EXL I in May 2012 and received $20.9 million in cash as compensation for damages incurred in 2012 for repair costs to and loss of use of the rig. Such amount was recognized as a component of operating income in the six months ended June 30, 2014 . Material Charges and Other Operating Expenses – Material charges for the three months ended June 30, 2015, included a $5.0 million adjustment to an estimated liability in connection with the HSOG shipyard dispute (see Note 4). Material charges for the three months ended June 30, 2014 included an $8.3 million noncash impairment charge for the carrying value of the Company's sole aircraft, which had been used to support operations. The asset had a carrying value of $12.7 million prior to the write-down. The amount of the impairment was based on actual sales prices for similar equipment obtained from a third-party dealer of such equipment. The aircraft was sold later in 2014 at an immaterial loss.
