「Are We Drilling For Oil In The U.S.」を編集中

<br>The explosion and fire that destroyed the Deepwater Horizon drilling rig within the Gulf of Mexico in April 2010 killed 11 crew members and  [https://asteroidsathome.net/boinc/view_profile.php?userid=873115 outdoor trimming tool] triggered an environmental nightmare. Before the well was finally capped in mid-July, virtually 5 million barrels of oil had been spilled into the Gulf, the National Oceanic and Atmospheric Administration reported, causing catastrophic damage for marine and plant life. Federal investigators found that the disaster was the result of a number of errors made by oil company BP, including an improperly cemented seal on the properly that allowed oil to leak, and the company's failure to perform up-to-par maintenance and security exams and to adequately practice the rig's crew,  [http://stephankrieger.net/index.php?title=Benutzer:JacquelynZog outdoor trimming tool] in accordance with Time. Within the aftermath of the incident, critics warned that drilling for oil more than a mile underneath water is inherently dangerous, since tools must withstand intense stress,  [https://pipewiki.org/wiki/index.php/User:ShelliRoller836 outdoor trimming tool] and the methods used to cap leaks at lesser depths might not work.<br><br><br><br>Nevertheless, six months after the accident, U.S. Secretary of the Interior Ken Salazar determined to allow deep-water drilling to resume, offering that operators comply with newly imposed, tighter safety requirements. One of many causes of the Deepwater Horizon catastrophe was the failure of cement sealing, which lined the opening bored within the Gulf flooring and held the pipe that goes down by the rig in place. New federal regulations require that an engineer certify that the cementing can withstand the pressures to which it will likely be subjected. BP says that sooner or  [https://wiki.lovettcreations.org/index.php/Potentially_Our_Most_Well-rounded_Shear Wood Ranger Power Shears review] [http://mdias.online/doku.php?id=paul_mcca_tney_is_dead:music_s_most_wtf_conspi_acy_theo_ies Wood Ranger Power Shears review] [https://git.tech.troyrc.com/christaldoolet electric power shears] [http://8.140.53.137:3000/lakeshaz668064/wood-ranger-power-shears-official-site8635/wiki/With+these+High-Quality+Tools+In+Hand Wood Ranger Power Shears website] price later, it is not going to take its building contractors' word that its wells are sturdy enough to withstand the extreme pressures to which they're going to be subjected. Instead, the company would require laboratory testing of the cement used within the parts of wells that'll be below essentially the most stress. This testing will be finished by either a BP engineer or an unbiased inspector.<br><br><br><br>Some specialists assume BP and different oil drillers ought to go even further to strengthen wells. For instance, oil industry engineers instructed Technology Review that the design of the Deepwater Horizon's nicely was fatally flawed due to BP's determination to put in a continuous set of threaded casting pipes -- essentially, one long pipe -- from the wellhead down to the bottom of the effectively. That method seals off the area between the pipe casing and the bore hole drilled for the nicely, making it troublesome to detect leaks that develop throughout building, and permits fuel from the oil deposit more time to build up and percolate, elevating the chance of an explosion. Instead, critics need to see oil wells in-built items, with each part of pipe cemented in place earlier than the following one is installed. That gradual, cautious method would enable builders to look ahead to leaks that might develop whereas the concrete is setting, and to repair them more easily.<br><br><br><br>Unfortunately, it also can be costly. The BOP's operate is to forestall fuel and oil from dashing too shortly up into the pipe inside the rig,  [https://www.simsonq.com/index.php/Central_African_Shear_Zone outdoor trimming tool] which could cause the type of explosion that destroyed the Deepwater Horizon. Imagine pinching a rubber hose along with your fingers to stop the circulate of water, and you have the basic concept, besides that your hand must be more than 50 ft (15 meters) in size and weigh greater than 300 tons, according to Newsweek. Instead of fingers, the BOP is equipped with a powerful software known as a shear ram, which cuts into the pipe to shut off the move of oil and gas. Unfortunately, in the Deepwater Horizon catastrophe,  [http://www.career4.co.kr/bbs/board.php?bo_table=ci_consulting&wr_id=136725 outdoor trimming tool] the BOP did not do its job. Federal regulators hope to stop those issues the following time round by requiring better documentation that BOPs are in working order, and higher training for crew members who operate them. As added insurance, they now mandate that BOPs be outfitted with extra highly effective [https://wiki.fuzokudb.com/fdb/The_7_Best_Knife_Sets_In_Keeping_With_Our_Tests Wood Ranger Power Shears features], able to chopping through the outer pipe even when subjected to the very best water strain expected at that depth.<br><br><br><br>Additionally, BP says that at any time when one of its undersea BOPs is dropped at the floor for testing and  [https://pipewiki.org/wiki/index.php/S160_TRUMPF_Shears outdoor trimming tool] upkeep, it would usher in an unbiased inspector to confirm that the work is being accomplished correctly. Some oil trade engineers argue that new BOP measures ought to go further. They'd wish to see rigs geared up with a second backup BOP -- ideally one floating on the surface, moderately than on the ocean floor, so it could be extra accessible to regular inspection and testing. In deepwater oil drilling, robots are the roughnecks who get probably the most troublesome jobs finished. Oil corporations have been utilizing remotely operated automobiles (ROVs) -- basically, robot submarines that can descend to depths where no human diver may survive -- for more than 30 years, to do every little thing from turn bolts to close valves. Today's state-of-the-art ROV is a $1 million, box-shaped steel craft the scale of a small car, equipped with mechanical arms that may lift as much as a ton in weight.<br>
