Deepwater Horizon disaster: the names of the guilty parties

The news agency Reuters has published the factbox including the companies involved in the Deepwater Horizon rig construction and management, all co-responsible for the environmental disaster in the Gulf of Mexico.

Transocean Ltd (RIGN.S) (RIG.N) – The company based Switzerland, is the owner of the oil platform Deepwater Horizon. The rig went into service in 2001 for a geophysical survey in the area of Macondo, starting from 40 miles off the coast of Louisiana.


BP Plc (BP.L) (BP.N) – British Petroleum hired the oil rig from Transocean for 500,000 dollars per day. BP is the project’s operator, from which it obtains 65% of profits.


Anadarko Petroleum Corp (APC.N) – The Houston company owns a 25% of non-operating interest in the well.


Cameron International Corp (CAM.N) – The Houston company supplied a piece of equipment known as a blowout preventer. Blowout preventers are put in place to stop an uncontrolled flow of oil or gas. The Deepwater Horizon’s blowout preventer failed to operate and seal the well.


Halliburton Co (HAL.N) – The oilfield services company, which has headquarters in Dubai and Houston, provided a number of services on the Deepwater Horizon. The company was providing cementing on the well to stabilize its walls, according to Transocean’s website.
