NEW ORLEANS —
The spill exposed lax government oversight and led to a temporary ban on deepwater drilling while officials and the oil industry studied the risks, worked to make it safer and developed better disaster plans.
BP's environmentally-friendly image was tarnished, and independent gas station owners who fly the BP flag claimed they lost business from customers who were upset over the spill. BP chief executive Tony Hayward stepped down after the company's repeated gaffes, including his statement at the height of the crisis: "I'd like my life back."
The cost of BP's spill far surpassed the Exxon Valdez spill in 1989. Exxon ultimately settled with the U.S. government for $1 billion, which would be about $1.8 billion today.
The government and plaintiffs' attorneys also sued Transocean Ltd., the rig's owner, and cement contractor Halliburton, but a string of pretrial rulings by a federal judge undermined BP's legal strategy to pin blame on them.
At the time of the explosion, the Deepwater Horizon was drilling into BP's Macondo well. The rig sank two days later.
After several attempts failed, engineers finally were successful in capping the well on July 15, 2010, halting the flow of oil into the Gulf of Mexico after more than 85 days.
The disaster also created a new lexicon in American vocabulary — such as top kill and junk shot — as crews used innovative solutions to attempt to plug the spewing well with pieces of rubber. As people all over the world watched a live spill camera on the Internet and television, the Obama administration dealt with a political headache, in part because the government grossly underestimated how much crude was spilling into the Gulf.
U.S. District Judge Carl Barbier in New Orleans was assigned to oversee tens of thousands of court claims spawned by the explosion. A trial date was set, but Barbier postponed it so BP could hammer out a deal with attorneys for Gulf Coast shrimpers, commercial fishermen, charter captains, property owners, environmental groups, restaurants, hotels and others who claim they suffered economic losses after the spill. Relatives of workers killed in the blast also sued.
