Deepwater Horizon In Flames

Deepwater Horizon was an ultra-deepwater, dynamically positioned, semi-submersible drilling rig (oil rig) built in 2001. The purpose of this rig was to drill oil wells deep underwater, moving from location to location, as needed. Once the drilling was complete, pumping production was handled by other equipment. Deepwater Horizon was owned by Transocean and leased to BP through September 2013. In September 2009, she drilled the deepest oil well in history. Deepwater Horizon sank on April 22, 2010, as the result of an explosion two days earlier.
