In April 2010, the oil rig you are referring to is likely the Deepwater Horizon, which was a semisubmersible offshore drilling unit. This rig exploded on April 20, 2010, in the Gulf of Mexico, leading to one of the worst environmental disasters in U.S. history. The explosion killed 11 workers and resulted in a massive oil spill that released millions of barrels of oil into the Gulf over several months. This incident caused extensive damage to marine and wildlife habitats and to the Gulf's fishing and tourism industries. The spill prompted widespread criticism of BP, the company operating the rig, along with the broader oil and gas industry, and led to significant legal and regulatory changes.
