Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2 below):

As previously disclosed, on December 3, 2015, Offshore Group Investment Limited, a Cayman Islands exempted company (“OGIL”), a wholly-owned subsidiary of Vantage Drilling Company (the “Company”), and certain subsidiaries of OGIL (together with OGIL, the “Vantage Debtors”) filed voluntary petitions (“Bankruptcy Petitions”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) seeking relief under the provisions of chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) to pursue a pre-packaged chapter 11 plan of reorganization (the “Plan”). During the pendency of the Bankruptcy Petitions, the Vantage Debtors continued to operate their business as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code.

On January 15, 2016, the Bankruptcy Court entered an order confirming the Plan. The JOLs (as defined below) have been advised by the Vantage Debtors that the Vantage Debtors closed the refinancing transactions under the Plan, and the Plan became effective on February 10, 2016. As a result of the effectiveness of the Plan, the Vantage Debtors, including OGIL, are no longer subsidiaries of the Company.

The Company’s previously reported liquidation proceedings in the Cayman Islands are continuing, and on January 18, 2016, the Grand Court of the Cayman Islands (the “Cayman Court”) appointed Alex Lawson and Kris Beighton of KPMG in the Cayman Islands as joint official liquidators (“JOLs”) of the Company.

Effective February 10, 2016, the Company received resignations from (1) all of the directors of the Company, (2) the principal executive officer and president of the Company, (3) the principal financial and accounting officer of the Company, (4) the principal operating officer of the Company and (5) each other named executive officer of the Company.

As a result of the Cayman Court’s order on January 18, 2016, the JOLs will manage the Company’s liquidation and have assumed full control of the Company’s affairs subject to the Cayman Court’s supervision. The JOLs have full authority to act on behalf of the Company, including the signing of periodic reports to the Securities and Exchange Commission.

The information set forth above in Item 1.03 and Item 5.02 of this Form 8-K is incorporated herein by reference.

On February 10, 2016, in connection with the Plan, OGIL issued a press release, a copy of which is filed herewith as Exhibit 99.1.

In accordance with General Instruction B.2 to Form 8-K, the information provided under this Item 7.01 shall be deemed to be “furnished” and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”). The Company does not undertake to update the information as posted on its website; however, it may post additional information included in future press releases and Forms 8-K, as well as posting its periodic Exchange Act reports.
