Transocean

Transocean Ltd. is one of the world's largest offshore drilling contractors. The company rents floating mobile drill rigs, along with the equipment and personnel for operations, to oil and gas companies at an average daily rate of US$282,700 (2010). Transocean's day rates extend as high as US$650,000 for its deep-water drillships, which house dual activity derricks and can drill in ultra-deep ocean depths of 10,000 ft (3,000 m). Recently, Transocean has been implicated in the Deepwater Horizon oil spill resulting from the explosion of one of its oil rigs in the Gulf of Mexico.

Transocean employs more than 18,000 people worldwide and has a fleet of 135 offshore drilling units and two ultra-deepwater units under construction, as of December 2011. The company is based in Vernier, Switzerland, near Geneva, and has offices in 20 countries, including Switzerland, the United States, Norway, Scotland, Brazil, Indonesia and Malaysia. The firm owns nearly half of the 50 or so deepwater platforms in the world.
