Noncontrolling Interest [Abstract]
Consolidated Joint Ventures	Note 3— Consolidated Joint Ventures On December 3, 2019, we completed a transaction with a subsidiary of Royal Dutch Shell plc (“Shell”), in which Shell bought out the remaining term of its drilling contract for the drillship Noble Bully II for $166.9 million, and we acquired Shell’s 50 percent interests in the Bully I and Bully II joint ventures for $106.7 million. As a result of this transaction, the former joint venture entities became our wholly-owned subsidiaries. Shell’s equity interests were presented as noncontrolling interests on our condensed consolidated financial statements. During the three months ended March 31, 2019, the Bully joint ventures approved and paid dividends totaling $10.0 million. Of these amounts, 50 percent was paid to our former joint venture partner, Shell.
