The Deepwater Horizon oil spill (also referred to as the BP oil spill, the BP oil disaster, the Gulf of Mexico oil spill, and the Macondo blowout) is an industrial disaster that began on April 20, 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect. government estimated the total discharge at 4.9 million barrels (210 million US gal; 780,000 m In Louisiana, 4,900,000 pounds (2,200 t) of oily material was removed from the beaches in 2013, over double the amount collected in 2012.
Mud and cement were later pumped in through the top of the well to reduce the pressure inside it which didn't work either.
A final device was created to attach a chamber of larger diameter than the flowing pipe with a flange that bolted to the top of the blowout preventer and a manual valve set to close off the flow once attached.
As of July 2011, about 491 miles (790 km) of coastline in Louisiana, Mississippi, Alabama and Florida were contaminated by oil and a total of 1,074 miles (1,728 km) had been oiled since the spill began.
Concerns were raised about the appearance of underwater, horizontally extended plumes of dissolved oil.
One study released in 2014 reported that tuna and amberjack that were exposed to oil from the spill developed deformities of the heart and other organs that would be expected to be fatal or at least life-shortening and another study found that cardiotoxicity might have been widespread in animal life exposed to the spill. government September 2011 report pointed to defective cement on the well, faulting mostly BP, but also rig operator Transocean and contractor Halliburton.
Numerous investigations explored the causes of the explosion and record-setting spill. Earlier in 2011, a White House commission likewise blamed BP and its partners for a series of cost-cutting decisions and an inadequate safety system, but also concluded that the spill resulted from "systemic" root causes and "absent significant reform in both industry practices and government policies, might well recur".In November 2012, BP and the United States Department of Justice settled federal criminal charges with BP pleading guilty to 11 counts of manslaughter, two misdemeanors, and a felony count of lying to Congress.BP also agreed to four years of government monitoring of its safety practices and ethics, and the Environmental Protection Agency announced that BP would be temporarily banned from new contracts with the US government.Pumping continued for eight hours, at the end of which time the well was declared to be "in a static condition." In January 2013, BP said that they were continuing to investigate possible sources of the oil sheen.Chemical data implied that the substance might be residual oil leaking from the wreckage.On July 15 the device was secured and time was taken closing the valves to ensure the attachment under increasing pressure until the valves were closed completing the temporary measures. Energy Department said that "neither Energy Secretary Steven Chu nor anyone else" ever considered this option.Tags: Adult Dating, affair dating, sex dating
