deepwater horizon oil spill bioremediation

[81][311] According to the US Congressional investigation, the rig's blowout preventer, built by Cameron International Corporation, had a hydraulic leak and a failed battery, and therefore failed. This is done through the production of proteins and other cellular elements that require a large amount of nitrogen, phosphorous and sulfate. [342][344], On 14 November 2012, BP and the US Department of Justice reached a settlement. Thus, oil that would normally rise to the surface of the water was emulsified into tiny droplets and remained suspended in the water and on the sea floor. One of the largest oil spills, known as the Deepwater Horizon oil spill, occurred in the Spring of 2010 near the coast of Louisiana (USA) due to an explosion during oil drilling activities. ASM Connect. [319] Still another was for not plugging the pipe with cement. After the explosion, oil gushed from the sea floor releasing an estimated 5.84x108 litre of crude oil into the ocean [11] . [146], Underwater injection of Corexit into the leak may have created the oil plumes which were discovered below the surface. In the case of the Deepwater Horizon oil spill, clean-up workers treated the oil with over 1.4 million gallons of various chemical dispersants. The Deepwater Horizon oil spill that occurred in 2010 was one of the most devastating oil spills in history. NWF senior scientist Doug Inkley notes that the marine death rates are unprecedented and occurring high in the food chain, strongly suggesting there is "something amiss with the Gulf ecosystem". "[351][352] The Supreme Court of the United States later refused to hear BP's appeal after victims and claimants, along with numerous Gulf coast area chambers of commerce, objected to the oil major's efforts to renege on the Settlement Agreement. The goal of NRDA is to restore natural resources and compensate the public for lost recreational use., we evaluated the type and amount of restoration needed in order to return the Gulf to the condition it would have been in before the spill and to compensate the public for the natural resource services that were injured or lost. The disaster had a significant impact on the environment and the local economy, and it highlighted the . On April 20, 2010, an explosion occurred on the Deepwater Horizon drilling platform in the Gulf of Mexico. The goal of the $500 million, 10-year research initiative, known as, Gulf Coast Ecosystem Restoration Trust Fund, Transocean plead guilty to criminal charges, Detailed allocations and project information, North American Wetlands Conservation Fund. By 3 October 2012, federal response costs amounted to $850million, mostly reimbursed by BP. [272], On 28 April 2010, the National Energy Board of Canada, which regulates offshore drilling in the Canadian Arctic and along the British Columbia Coast, issued a letter to oil companies asking them to explain their argument against safety rules which require same-season relief wells. The genes code for ring-hydroxylating dioxygenases, which are necessary to cleave the aromatic rings of PAH [4]. ", "Limits on access to oiled waters, coast frustrates journalists", "It's BP's Oil': Running the Corporate Blockade at Louisiana's Crude-Covered Beaches, "BP's Photo Blockade of the Gulf Oil Spill: Photographers Say BP and Government Officials Are Preventing Them from Documenting the Impact of the Deepwater Horizon Disaster", "Dying, dead marine wildlife paint dark, morbid picture of Gulf Coast following oil spill". While this technique had worked in shallower water, it failed here when gas combined with cold water to form methane hydrate crystals that blocked the opening at the top of the dome. [81][324] This fund was set aside for natural resource damages, state and local response costs, and individual compensation, but could not be used for fines or penalties. On October 5, 2015, we proposed a comprehensive, integrated, ecosystem restoration plan to address impacts from the spill to the Gulf of Mexico. [33][34] BP was the operator and principal developer of the Macondo Prospect with a 65% share, while 25% was owned by Anadarko Petroleum, and 10% by MOEX Offshore 2007, a unit of Mitsui.[35]. As many as 8.3 billion oysters were lost. [181] They also said that they wanted to provide access to the information while maintaining safety. [263][264][265] The U.S. Travel Association estimated that the economic impact of the oil spill on tourism across the Gulf Coast over a three-year period could exceed approximately $23billion, in a region that supports over 400,000travel industry jobs generating $34billion in revenue annually. "[246] ProPublica reported that workers were being photographed while working with no protective clothing. [308] The National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling was established on 22 May to "consider the root causes of the disaster and offer options on safety and environmental precautions. [3] After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. The fines from the criminal cases administered by the National Academies of Science offsite link and the National Fish and Wildlife Foundation offsite link are used for two programs: After the spill, state and federal agencies undertook an intense scientific study of the impacts of the spill. The oil well over which it was positioned was located on the seabed 4,993 feet (1,522 metres) below the surface and extended approximately 18,000 feet (5,486 metres) into the rock. [92] On 19 September 2010, National Incident Commander Thad Allen declared the well "effectively dead" and said that it posed no further threat to the Gulf. Tens of billions of dollars in liability and fines were at stake. With the damaged riser shorn from the LMRPthe top segment of the BOPthe cap was lowered into place. Deepwater Horizon Oil Spill Crude oil is shown in the Pacific Ocean offshore of Orange County, California, Oct. 3, 2021. The North American Wetlands Conservation Fund received $100 million from the court fines to support projects on wetlands restoration and conservation in the United States, Canada and Mexico. Louisiana will receive more than half the funding, $5 billion, since it saw the most significant damage from the spill. Once released, the natural gas traveled up a riser to the platform of the Deepwater Horizon oil rig that was over the well, where it ignited, killing 11 workers and injuring 17. [59] The Republic of the Marshall Islands Maritime Administrator conducted a separate investigation on the marine casualty. An official website of the United States government. BP pled guilty in 2012 to 14 felony counts and was fined a record $4 billionand half directly benefits the Gulf. [339] BP also agreed to spend $105million over five years to set up a Gulf Coast health outreach program and pay for medical examinations. Post-oil spill samples on the other hand, contain mostly oil-degrading organisms with drastic decrease in diversity. 4 million barrels of oil flowed from the damaged Macondo well over an 87-day period, before it was finally capped on July 15, 2010. [228] A 2015 study of the relative toxicity of oil and dispersants to coral also found that the dispersants were more toxic than the oil. [60], Concerns were raised about the appearance of underwater, horizontally extended plumes of dissolved oil. [63][64][65], That means that over 10010^6USgal (380Ml) (2.4million barrels) remained in the Gulf.

If it proves to be oil from the subsurface, then that could indicate the possibility of an indefinite release of oil. [199][200] Fish with oozing sores and lesions were first noted by fishermen in November 2010. [52] On 10 July, the containment cap was removed to replace it with a better-fitting cap ("Top Hat Number 10"). [370][371], This article is about the oil spill itself. This webpage provides information and materials on EPAs enforcement response to the Deepwater Horizon Oil Spill, settlements with several of the defendants, including the record-setting settlement with BP Exploration & Production for an unprecedented $5.5 billion Clean Water Act penalty and up to $8.8 billion in natural resource damages. Gerald Baron for Crisisblogger, 8 June 2012. Including one-time use sorbent booms, a total of 13,300,000ft (4,100km) of booms were deployed. Also known as the Gulf of Mexico Oil spill and BP oil spill, the Deepwater Horizon oil spill is considered the largest oil spill in the petroleum industry's history. 2. Rather, it concluded that "notwithstanding these inherent risks, the accident of April 20 was avoidable" and that "it resulted from clear mistakes made in the first instance by BP, Halliburton and Transocean, and by government officials who, relying too much on industry's assertions of the safety of their operations, failed to create and apply a program of regulatory oversight that would have properly minimized the risk of deepwater drilling. "[296] BP's chief operating officer Doug Suttles contradicted the underwater plume discussion noting, "It may be down to how you define what a plume is here The oil that has been found is in very minute quantities. There was a microbial shift in the deepwater community as the chemistry and nature of the oil changed.
