The explosion and fire that destroyed the Deepwater Horizon drilling rig within the Gulf of Mexico in April 2010 killed 11 crew members and triggered an environmental nightmare. Before the nicely was lastly 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 discovered that the disaster was the results of a number of mistakes made by oil firm BP, [durable garden trimmer](https://merkelistan.com/index.php?title=The_Eleven_Best_Multipurpose_Kitchen_Shears) together with an improperly cemented seal on the effectively that allowed oil to leak, and the corporate's failure to carry out up-to-par maintenance and safety checks and to adequately prepare the rig's crew, in keeping with Time. In the aftermath of the incident, critics warned that drilling for oil greater than a mile below water is inherently risky, since [Wood Ranger Tools](http://8.219.68.133:3000/alexanderbrock/9320270/wiki/The+5+Best+Pruning+Shears+of+2025+Our+Editors+Recommend) should withstand intense strain, and the methods used to cap leaks at lesser depths could not work.

Nevertheless, six months after the accident, U.S. Secretary of the Interior Ken Salazar determined to permit deep-water drilling to resume, providing that operators adjust to newly imposed, tighter safety standards. One of many causes of the Deepwater Horizon disaster was the failure of cement sealing, [Wood Ranger Power Shears](https://docs.digarch.lib.utah.edu/index.php?title=Premium_Kitchen_Shears_For_Effortless_Cutting) which lined the outlet bored within the Gulf ground and held the pipe that goes down through the rig in place. New federal laws require that an engineer certify that the cementing can withstand [Wood Ranger Power Shears](http://rivonirecruitment.co.za/?p=22695) the pressures to which it will be subjected. BP says that in the future, it won't take its construction contractors' phrase that its wells are strong enough to withstand the excessive pressures to which they'll be subjected. Instead, the corporate would require laboratory testing of the cement used within the parts of wells that'll be underneath essentially the most stress. This testing might be accomplished by either a BP engineer or an unbiased inspector.

Some experts assume BP and other oil drillers ought to go even further to strengthen wells. For example, oil trade engineers informed Technology Review that the design of the Deepwater Horizon's nicely was fatally flawed due to BP's resolution to put in a continuous set of threaded casting pipes -- essentially, one lengthy pipe -- from the wellhead right down to the underside of the effectively. That technique seals off the house between the pipe casing and the bore gap drilled for the nicely, making it difficult to detect leaks that develop throughout building, and permits gasoline from the oil deposit extra time to build up and percolate, raising the chance of an explosion. Instead, critics need to see oil wells built in pieces, with every part of pipe cemented in place earlier than the subsequent one is installed. That gradual, cautious methodology would allow builders to watch for leaks which may develop while the concrete is setting, and to fix them extra easily.

Unfortunately, it also can be costly. The BOP's perform is to stop gas and oil from speeding too quickly up into the pipe contained in the rig, which could cause the type of explosion that destroyed the Deepwater Horizon. Imagine pinching a rubber hose along with your fingers to stop the movement of water, and you have the basic idea, besides that your hand would have to be greater than 50 ft (15 meters) in size and weigh more than 300 tons, based on Newsweek. Instead of fingers, [Wood Ranger Tools](https://freekoreatravel.com/index.php/Human_Uses_Of_Serration_Have_Copied) the BOP is equipped with a strong tool called a shear ram, which cuts into the pipe to shut off the circulate of oil and gas. Unfortunately, within the Deepwater Horizon catastrophe, the BOP didn't do its job. Federal regulators hope to forestall those issues the subsequent time around by requiring better documentation that BOPs are in working order, and better coaching for crew members who function them. As added insurance, they now mandate that BOPs be equipped with more powerful [Wood Ranger Power Shears](http://fsianp04.nayaa.co.kr/bbs/board.php?bo_table=sub05_03&wr_id=104147), capable of chopping through the outer pipe even when subjected to the best water stress anticipated at that depth.

Additionally, BP says that each time one in every of its undersea BOPs is delivered to the surface for testing and maintenance, [Wood Ranger Power Shears shop](https://dev.neos.epss.ucla.edu/wiki/index.php?title=3_In._By_2_In.) it is going to bring in an impartial inspector to verify that the work is being done properly. Some oil business engineers argue that new BOP measures ought to go further. They'd wish to see rigs outfitted with a second backup BOP -- ideally one floating on the surface, rather than on the ocean floor, so it may very well be more accessible to common inspection and testing. In deepwater oil drilling, robots are the roughnecks who get probably the most troublesome jobs carried out. Oil corporations have been utilizing remotely operated autos (ROVs) -- basically, robot submarines that can descend to depths the place no human diver may survive -- for greater than 30 years, to do every little thing from flip bolts to shut valves. Today's state-of-the-art ROV is a $1 million, box-formed steel craft the dimensions of a small car, equipped with mechanical arms that may carry up to a ton in weight.
