Deepwater Horizon
Deepwater Horizon was an ultra-deepwater, dynamically positioned, semi-submersible offshore drilling rig owned by Transocean. Built in 2001 in South Korea by Hyundai Heavy Industries, the rig was commissioned by R&B Falcon (a later asset of Transocean), registered in Majuro, and leased to BP from 2001 until September 2013. In September 2009, the rig drilled the deepest oil well in history at a vertical depth of and measured depth of in the Tiber Oil Field at Keathley Canyon block 102, approximately southeast of Houston, in of water.

On 20 April 2010, while drilling at the Macondo Prospect, a blowout caused an explosion on the rig that killed 11 crewmen and ignited a fireball visible from away. The fire was inextinguishable and, two days later, on 22 April, the "Horizon" sank, leaving the well gushing at the seabed and causing the largest marine oil spill in history.
