Deepwater Horizon; Gulf of Mexico.
Gulf of Mexico.
1. A fire and explosion occurred at approximately 11:00 PM CDT, April 20, 2010 on the Deepwater Horizon, a semisubmersible drilling platform, with more than 120 crew aboard. The Deepwater Horizon is located some 50 miles SE of the Mississippi Delta and contained an estimated 700,000 gallons of #2 Fuel Oil or Marine Diesel Fuel.
