History

Built originally for R&B Falcon, she was completed in 1999 by Samsung Heavy Industries in Geoje, South Korea. In 2001 R&B Falcon merged with Transocean Sedco-Forex. She is the third of four Deepwater Pathfinder class ships.

After initial work in the Gulf of Mexico, Deepwater Millennium has drilled wells off West and East Africa and Brazil.[4] With the exception of one well off Nova Scotia in the summer of 2002, she was in the Gulf continuously from 2001 to 2008. Her work includes wells for Kerr-McGee, Pioneer, Marathon Oil, Mariner, Chevron Corporation, Anadarko Petroleum, Statoil, and Petrobras.[5] More recently she was drilling off the coast of Western Australia on an 18-month contract for Woodside Petroleum.
