As of April, Burullus Gas terminated a contract for Transocean’s Deepwater India rig.

Independent Oil and Gas (IOG), the North Sea focused oil and gas company, has signed a rig contract with Transocean Drilling procuring the Transocean John Shaw semi-submersible rig to drill an appraisal well on the Skipper oil discovery in the UK sector of the North sea.

Steven Newman is stepping step down as president and CEO of Transocean Ltd., effective Feb. 16. Additionally, he is resigning as a director of Transocean. Until a permanent replacement is named, Ian Strachan, chairman of Transocean’s board, will serve as interim CEO.

Transocean , owner of the world's largest offshore drilling fleet, has put its Middle East rig assets up for sale, in a deal likely to raise $1 billion for the Switzerland-based company, three sources said.

Transocean Ltd. issued a monthly fleet update summary which includes newly signed contracts, significant changes to existing contracts, and changes in estimated planned out of service time of 15 days or longer for all rig classifications since the previously issued comprehensive fleet status report or fleet update summary.

BP Plc officials overseeing the Macondo well that spewed millions of gallons of oil into the Gulf of Mexico ignored questions about whether safety tests done hours before a fatal blast on the drilling rig were flawed, lawyers for Transocean Ltd. said in a court filing.

Oil giant BP has lost its attempt to shift over $15 billion (9 billion pounds) of costs related to the Gulf of Mexico oil spill onto contractor Transocean, increasing the possibility BP may have to foot the entire $42 billion clean up bill.

Another Transocean Ltd rig is leaving the deepwater Gulf of Mexico, still under contract with Statoil -- the fourth rig departure resulting from a moratorium on U.S. deepwater drilling.
