Transocean Provides New Fleet Update Summary

Transocean Inc. issued a new monthly fleet update summary covering only newly signed contracts, significant changes to existing contracts and changes to estimated out of service time of 60 days or more since our fleet status report dated August 5, 2008. The new monthly fleet update summary is intended to simplify the fleet review and modeling process for those following the company. Going forward, we will issue a comprehensive fleet status report covering Transocean's entire 137-rig fleet shortly after the end of each calendar quarter, and we will update such report during the intervening months by issuing monthly fleet update summaries.

Drilling rig status and contract information on the company's offshore drilling fleet has been condensed into a report titled Transocean Fleet Status Report, which is available through the company's website. The report can be accessed from the home page of the web address by clicking on the Fleet Update Report link found in the tool bar.
