deepwater horizon what happened



The rig owner, Transocean, had a "strong overall" safety record with no major incidents for 7 years.In 2008 and 2009, the surveys ranked Transocean last among deep-water drillers for "job quality" and second to last in 'overall satisfaction'. • Deepwater Horizon Response from the Deepwater Horizon Unified Command (U.S. Government/BP/Transocean) Scientists noted that the prevailing paths of the Gulf of Mexico's Loop Current and a detached eddy located to the west kept much of the oil, which covered a sizable part of the gulf some three months after the accident, … Due to this change if you are seeing this message for the first time please make sure you reset your password using the About 4.9 million barrels of oil leaked out into the Gulf of Mexico during the industrial disaster that claimed 11 lives Deepwater Horizon is regarded as the largest marine oil spill in history, after flooding about 68,000 square miles in the Gulf of Mexico and killing 11 (Credit: Wikimedia Commons/US Coast Guard)It has been ten years since one of, if not the darkest days in the oil industry’s history – the Deepwater Horizon oil spill.The disaster took place 41 miles off the coast of Louisiana, US in the It is regarded as the largest marine oil spill in history, having contaminated about 68,000 square miles of the Gulf, killing 11 crew members and leaving a devastating impact on the thousands of species that inhabited the surrounding waters.The Deepwater Horizon rig, in the Macondo Prospect, was operated by Here, NS Energy takes a look at how the spill unfolded and the impact it had on the Gulf.The owner of Deepwater Horizon was offshore drilling company Transocean, which was attributed 30% of the blame for its role in the disaster.It leased the rig to BP, which has shouldered 67% of the liability, while US energy giant  Halliburton picked up 3% of the responsibility for its role as a cement contractor for the project.The oil well was located more than 18,000 feet below sea level and operated in water depths of up to 5,000 feet.Flames then engulfed Deepwater’s platform, putting the lives of the 126 crew members on board at risk – seven of which were from BP, alongside 79 from Transocean, while the remaining employees were contractors from various other companies.Most workers were rescued by lifeboats or helicopters, but 11 crew members were not found, and were later judged to have died in the aftermath of the explosion.The rig sank to the lower depths of the ocean two days later, the same day that BP claimed to have found the cause of the oil leak.In May 2010, Transocean began drilling two relief wells, which are intended to intersect an oil or gas well that has experienced a blowout.After months of working round the clock to stem the spill, it was announced the operation had been successful in plugging the Deepwater well in September 2010, when former US national incident commander Thad Allen declared the well “effectively dead”.After leaking for 87 days, BP estimated that there had been a flow rate of between 1,000 and 5,000 barrels per day (bpd).But the Flow Rate Technical Group (FRTG) — a group of scientists and engineers from the US federal government, universities, and research institutions brought together for an official scientific-based estimate — claimed the initial flow rate was in fact 62,000 bpd – giving an overall total of 4.9 million barrels.But the company continued with its lower estimations and argued that the government figures did not reflect more than 810,000 barrels of oil that had either been collected or burned before it could enter the ocean.The spill had a devastating effect on the region, with marine life and the coastlines of Louisiana, Mississippi, Alabama, and Florida swimming in oil — which had a knock-on effect for many businesses and fisherman.To reduce the spread of oil, floating booms stretched across 4.2 million feet, and almost two million gallons of dispersants were used to remove as much of the oil from the water as possible.Following government pressure, BP created a $20bn fund to compensate those hit hardest by the disaster.An investigation was launched in June 2010 by the US Department of Justice (DOJ), before it would go on to sue BP, Transocean, and Anadarko — a minority owner of the well — in December 2010 for violating the Clean Water Act and Oil Pollution Act.In 2013, Transocean paid a $1bn civil penalty and a $400m criminal penalty before resolving a $212m claim in 2015.Anadarko forked out $160m for its role at the rig, while Halliburton agreed to pay a $1.1bn settlement.It also paid a $200,000 fine after it was revealed employees had destroyed evidence related to the spill.BP has paid out up to $75bn to help with the clean-up costs and the charges imposed, which included an $18.7bn fine — marking the highest-ever penalty imposed by the US government against an individual company.Five Predictions as We Enter the Age of the Energy Transition

Deepwater Horizon oil spill of 2010: path of the oil Map depicting the effects of the Deepwater Horizon oil spill, caused by the explosion of an oil rig off the coast of Louisiana on April 20, 2010. After burning for more than a day, On September 8, BP published a report that suggested that the ignition source was the released gas entering the air intakes of the diesel generators, and engulfing the deck area where the exhaust outlets for the main generators were emitting hot exhaust gas.According to officials, 126 people were on board, of whom 79 were Transocean employees, seven were from BP, and 40 were contracted; several of the BP and Transocean executives were on board for a tour of the rig, maintenance planning, annual goals review, a "Drops" safety campaign, and to congratulate the senior staff of the rig for 7 years of operations without a lost time incident.The Coast Guard interviewed the uninjured workers on the Initial reports indicated that between 12 and 15 workers were missing;On the morning of April 22, Coast Guard Petty Officer Ashley Butler stated that "oil was leaking from the rig at the rate of about 8,000 barrels (340,000 US gallons; 1,300,000 litres) of crude per day. By James Murray 20 Apr 2020 . The rig won an award from the MMS for its 2008 safety record, and on the day of the disaster, BP and Transocean managers were on board to celebrate seven years without a lost-time accident. A decade on, the continuing tragedy of Deepwater Horizon and fears it could happen again. A BP spokesman said rigs hired by BP have had better safety records than the industry average for six years running, according to MMS statistics that measure the number of citations per inspection. Among the offshore accidents in recent history, the Deepwater Horizon explosion, and the subsequent oil spill, is considered to be the largest oil spill in history, as well as one of the most tragic.

BP's costs for the clean-up, environmental and economic damages and penalties had reached $54bn.This article is about the explosion of the drilling rig On April 21, 2011, BP filed $40 billion worth of lawsuits against rig owner Transocean, cementer Halliburton and blowout-preventer manufacturer In September 2014, Halliburton agreed to settle a large percentage of legal claims against it over the Deepwater spill by paying $1.1 billion into a trust by way of three installments over two years.In July 2015 BP reached an $18.7bn settlement with the US government, the states of Alabama, Florida, Louisiana, Mississippi and Texas, as well as 400 local authorities.

Deepwater Horizon a decade on: What happened in the infamous oil spill. Mr. Odone wouldn't comment on BP's relationship with Transocean after the Gulf disaster but said BP continues to use Transocean rigs.In February 2009, BP filed a 52-page exploration and environmental impact plan for the Macondo well with the Internal BP documents show that BP engineers had concerns as early as 2009 that the metal casing that BP wanted to use might collapse under high pressure.In March 2010, the rig experienced problems that included drilling mud falling into the undersea oil formation, sudden gas releases, a pipe falling into the well, and at least three occasions of the blowout preventer leaking fluid.The blowout preventer was damaged in a previously unreported accident in late March.By April 20, the operation was running five weeks late.An April draft of a BP memo warned that the cementing of the casing was unlikely to be successful.BP Vice President of drilling, Patrick O'Bryan, was on the platform two hours prior to the explosionPreliminary findings from BP's internal investigation indicated several serious warning signs in the hours prior to the blowout.Transocean employees on the vessel stated that the electric lights flickered, followed by two strong vibrations.
