on april 20 2010 the deepwater horizon dwh an oil rig working for british petroleum bp on the macondo exploration well in the gulf of mexico exploded and was engulfed in flames which took the lives of 11 people and approximately seventeen were injured. it burned and sank to the ocean floor. the explosion damaged the oil pipes which caused the release of between 3.26 and 5 million barrels of oil or 205.8 million gallons into the gulf of mexico. the british petroleum bp oil spill has since transformed into one of the most exceedingly bad fiascos turning into the biggest accidental marine oil spill in history. in a couple hours they would have been prepared to move the drilling apparatus off location so the completion apparatus could proceed onward. the blowout and oil spill caused by an imperfect well arrangement that did exclude enough concrete between the 7-inch generation packaging and the 9 7/8-inch security packaging. the assumed blowout preventer bop failure is an essential yet secondary issue. despite the fact that the subsequent oil spill has possibly grave environmental ramifications recent endeavors to constrain the stream with an insertion tube have evidently been viable. continuous endeavors to moderate or stop the stream incorporate drilling two adjacent alleviation wells were made to provide converge for the mc 252 wellbore within 60-90 days. at 22:00 the rig unexpectedly started to shake and a noisy surging clamor was joined by natural gas drilling mud and ocean water shot high over the floor of the bore ship. the gas detonated and the rig was overwhelmed in flames. the deepwater horizon dwh was about 19 times the size of exxon valdez oil spill of 1989 which was the largest oil spill in the u.s before the deepwater horizon spill. while the extent of the environmental damage is unknown it was an ecological disaster that has the potential to cause long-term economic and environmental damage. the use of chemical dispersants to break up the oil before it reached shore may have aggravated the damage. while the degree of the environmental damage is obscure the gulf tourism was affected quite drastically by the oil spill in the region affected by hurricane katrina. the seafood was affected as well especially shrimps and oysters. the fishing companies had not yet recovered from the effects of hurricane katrina when it was hit by what seemed to be a new economic and ecological disaster. by early june many laborers had just been admitted to medicals focuses with manifestations going from shortness of breath to queasiness and warm front.the bp oil spill is the aftereffect of a progression of occasions that in the long run led to thousands of barrels of oil spilling into the gulf of mexico. toward the beginning of september bp discharged a report that examined the occasions leading up to the disaster. the article communicates that the fire was caused by an entry of hydrocarbons from the well and a short time later onto the oil rig bp internal investigation team the deepwater horizon was fitted with safeguard frameworks in case anything turned out gravely. all of the fail-safes flopped. the three pipes broke after the rig sank. that is the point at which the spill happened. the u.s. department of health and human services asked the institute of medicine iom to gather a workshop that would examine the effects of the oil spill. on june 22 and 23 leading health experts from around the world held a meeting in new orleans. the meeting was attended by roughly 400 participants and was addressed by thirty-five speakers.some reports state that as much as 16 percent of the 5 million barrels of oil that was spilled into the gulf of mexico may have settled into the ocean floor inwards of a 40-kilometer radius of the damaged oil rig. that oil may account up to 30 percent of the approximately 2 million barrels of oil that scientists suspect never reached the ocean surface. david valentine of the university of california santa barbara led a research and found the submerged oil by searching for hopane which is a component of oil that is not separated easily. the team mapped patches of the remaining oil to be in a 3 200-square-kilometers region around the well by analyzing more than 3 000 ocean sediment samples from 534 locations in the gulf of mexico. the researchers reported on october 27 in the proceedings of the national academy of sciences that the remaining oil which never surfaced may still be hiding elsewhere in the ocean.the most shocking part of the oil spill was that all of this could have been prevented. consistently british petroleum bp has demonstrated a disturbing measure of unfortunate behavior including government violations. lawful issues began as recent as 1998 when a temporary worker was caught dumping several gallons of poisonous waste into a well opening. an investigation of state and government records demonstrate that british petroleum bp is most noticeably the worst in the business as far as oil spills go and even safety violation. since 1990 british petroleum bp has had fifty-two safety violations in alaska alone. an explosion went off at one of british petroleums bp refineries in 2005 in texas city texas. 15 were slaughtered while 170 were left hurt. indeed even after every one of these infringements the administration kept on supporting british petroleum bp as per white house natural counselor carol browner the administration did not consider british petroleums bp long record of safety violations and ecological accidents an issue. the administration had the ability to prevent british petroleum bp from additionally penetrating yet rather they picked not to. the piper alpha was operated by occidental petroleum caledonia ltd. this disaster is a similar oil spill catastrophe which took place at the 15/17 north sea near the coast of scotland. an explosion occurred on july 6 1988 at about 22:00. within seconds a major unestablished crude-oil fire developed engulfing most of the upper and lower platform in smoke. only the wellhead area of the platform was not on fire. it took the life of 167 onboard workers leaving several injured and near a total loss of the rig keeping one of the three modules on the rig from drowning in what was the worlds worst offshore accident at the time. there was a chain of explosions and the complete malfunction of the security alarms that led to such a huge collateral damage. the piper platform proved to be extremely productive producing up to 360 000 barrels of oil per day. the platform was producing 125 000 barrels of oil per day at the time of the disaster. the oil was exported ashore through sub-sea line 128 miles long to the onshore terminal on the island of flotta in the orkneys. it represented about 10 percent of the uks oil production. the rebuilding cost of the platform has been in excess of £1 billion and the safety-related modifications and the development of safety cases and follow-up work has been estimated to exceed £5 billion. the piper alpha disaster was caused by a massive fire which was the result of an unpredictable accident but caused by an accumulation of errors and questionable decisions. the destruction of the platform was caused by an explosion and the subsequent massive oil and gas fire showed that the potential hazards of the offshore rigs. the main reason for this disaster was initiated by the maintenance team which was working on one of the two gas condensate pumps which were stopped for maintenance. in order to carry out the procedure the team first had to bolt shut the failsafe valve before initiating the pump maintenance. it was later discovered by the investigation team that the failsafe valve was not tight enough to contain the immense pressure of the pumped lpg condensate by the switched pump. while working on the pump in the daytime the shift at that time realized that the pump could not be fixed in the span of the day and had to postpone the maintenance to the next day. after a while the other lpg pump stopped working for an unknown reason and the production manager had to make a desperate decision to switch to the pump that was under maintenance ignoring standard procedure and probably unaware that the fail-safe valve was actually going to fail resulting in massive leakage of condensate near the surroundings of the chamber. once it caught fire it spread very rapidly resulting in this catastrophe. brad matsen jacques cousteau: the sea king started his research on the piper alpha oil rig in 2008 two years before the deepwater horizon disaster. matsens exhaustive detailing is filled with shock as he puts forth the defense that our dependence on oil as an energy source nearly ensures fatalities since exploration capture refining and transportation are implicitly hazardous. in his two-year investigation he gathered a good amount of essential information from company bosses rig foremen and workers first responders medical staff and government officials. he states that the piper alpha complex was a junction station for moving gas to other platforms alongside drilling and production of gas. matsen adds the piper alpha disaster to the list while detailing the adverse history of fires explosions even collapses of rigs. he states that rig work is one of the most dangerous jobs on earth. his book is an appreciation to the survivors and their families who protested against occidental petroleum which cleared itself from all the blame in this disaster. raping it up the similarities between the two disasters is the lack of minute engineering and safety mistakes that were made before the disasters resulting in a huge catastrophe. strategies should be set up that guarantees that legitimately prepared staff are nearby consistently to guarantee the wellbeing of the boring procedure. just experienced faculty could appropriately respond to a crisis and perhaps have the capacity to alleviate additional harm. information and experience are required to perceive potential risks in time and counteract considerably greater negative impacts. the engineers most likely did not have the jurisdiction to ask for the work to be halted so further examinations could be made. politics with the cash in question some of the time prompt hazardous choices. on the off chance that somebody with the expertise and authorization to settle on an official choice was there these disasters could have been averted.
