Transocean’s CFO steps down

The chief financial officer of offshore drilling contractor Transocean is stepping down from that role effective Monday, the company said Thursday.

Ricardo Rosa will retire from the company April 30. A search firm is helping find his successor.

Gregory Cauthen is returning to the Swiss-based Transocean as interim CFO.

He was a consultant to the company from September 2009-August 2010. Before retiring from Transocean in August 2009, he was the company’s CFO.

Transocean was the owner of the Deepwater Horizon rig that exploded and sank in the Gulf of Mexico. It was leased by BP for its Macondo well project.
