Explosion occurred in the center of the Gulf of Mexico on April 20, 2010. Thirteen crewmembers died during the explosion of the rig. Over the course of this time more than 60,000 oils were added to the oil film every day. In about a week, the problem was about 5000 feet under the sea surface and it turned out that the sea floor seal was broken well due to such high pressure. UWS how bad they were sent to check cracks at that time to understand how and when they can repair the well and stop the leak.
On April 20, 2010, BP 's Deepwater Horizon drilling rig exploded and became the largest artificial environmental hazard in the history of the Americas. Before the leak on July 15, 2010, an explosion killed 11 crewmen and released 4 million barrels of oil to the Gulf of Mexico. In addition to the widespread damage to the wildlife and the tourism industry on the Gulf, BP faces litigation and is paying fine of more than $ 4.5 billion. The most important reason is quality control failure. The contractor did not test the weak cement around the well, the well did not contain hydrocarbons in the reservoir and allowed flammable gas and liquid to flow into the production casing. A technician misunderstood the hydraulic test, the gas entered the engine room through the ventilation system and opened the way of ignition. After the explosion, the blowing prevention device of the oil drilling equipment at the seafloor could not start by closing the well
On 20th April 2010, the oil drilling equipment of Deepwater Horizon exploded and sunk into the Gulf of Mexico, 42 miles from the coast of Louisiana, causing long-term environmental hazards in the summer. At the time of drilling to Deepwater Horizon after July 15 to 87, 4.2 million barrels of oil leaked into the bay. Eleven employees of the rig died in the first explosion and the resulting oil spill resulted in the death of thousands of animals and devastating effects on coastal communities, especially those dependent on fisheries .
