Overview of Company

At the time of the explosion and sinking of the Deepwater Horizon oil rig into the Gulf of Mexico in April 2010, Transocean owned and operated the Deepwater Horizon, including the blow-out preventer and riser. BP Exploration and Production, Inc. (“BP”) contracted with Transocean for the operation of the Deepwater Horizon to drill the Macondo Well. (For more information on the 2010 Deepwater Horizon oil spill, see EPA Response to BP Spill in the Gulf). There are four Transocean corporate entities that were involved in the drilling and operation of the Deepwater Horizon and that are covered by this settlement: Transocean Deepwater Inc., Transocean Offshore Deepwater Drilling Inc., Transocean Holdings LLC, and Triton Asset Leasing GmbH (“the Transocean Defendants”).

Violations

The United States filed a complaint on December 15, 2010 in the U.S. District Court for the Eastern District of Louisiana alleging, among other things, that the Transocean Defendants violated Section 311 of the Clean Water Act, 33 U.S.C. § 1321. The claims alleged against the Transocean Defendants are based on discharges of oil into waters of the United States beginning on April 20, 2010 from the Macondo Well and the Deepwater Horizon, the mobile offshore drilling unit lost in the course of the blowout of the Macondo Well.

Health and Environmental Benefits

The injunctive relief required by the settlement to improve the safety of Transocean's oil drilling practices and to enhance its oil spill preparedness and response are designed both to prevent the likelihood of a future oil spill, and to minimize the adverse effects of a spill if it should happen. Oil spills are known to cause both immediate and long-term harm to human health and ecosystems. Oil prevents oxygen in water and can suffocate wildlife.

Oil emulsions may stick to the gills of fish or coat and destroy algae or other plankton. Floating oil may reduce water exposure to the circulation of oxygen and, in conjunction with emulsified oil, interfere with photosynthesis. Oil slicks can kill birds, contaminate food sources, reduce animal and plant reproduction and contaminate nesting habitats. Oil spills can cause long-term effects years later even if the oil remains in the environment for a relatively short period of time. Petroleum oils can also undergo oxidation and polymerization reactions and can form tars that persist in the environment for years.
