The notes will be guaranteed by Transocean Ltd. and certain of Transocean Inc.’s subsidiaries.

Transocean Inc. intends to use the proceeds from the Offering to repay in full and retire its 2017 Notes (as defined in the offering memorandum) upon the maturity thereof on October 15, 2017, to redeem all of itsoutstanding 2018 Notes (as defined in the offering memorandum) and to repay in full the amounts outstanding under its EksportfinansLoans due January 2018, as described in the offering memorandum. The remaining proceeds of the Offering areintended to be used for general corporate purposes.

A copy of the press release announcing the Offering is furnished herewith as Exhibit 99.1and is incorporated herein by reference.

In connection with the Offering, Transocean Ltd. disclosed in the offering memorandum related to the Offering that based on information available to management as of the date of the offering memorandum, it does not expect that its results of operations for the quarterly period ended September 30, 2017 will negatively compare to the guidance for such quarterly period that Transocean Ltd. has publicly disclosed on its August 3, 2017 earnings call. Such statements, however, are based on management's internal reporting, and its financial results for the quarterly period ended September 30, 2017 are not yet finalized and the closing procedures for that quarter are not yet complete. As such, Transocean Ltd.'s actual results may be materially different from such expectations and undue reliance should not be placed on such expectations. In addition, such expectations are not necessarily indicative of Transocean Ltd.'s results for any future period. No independent public accounting firm has performed any procedures with respect to the preliminary data for the quarterly period ended September 30, 2017, nor have they expressed any opinion or other form of assurance on such information.

The information in this Current Report on Form 8-K, including Exhibit 99.1, is being “furnished” to Item 7.01 and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and is not incorporated by reference into any Transocean Ltd. filing, whether made before or after the date hereof, regardless of any general incorporation language in such filing.
