The Transocean Deepwater Horizon rig 130 miles South East of New Orleans exploded on April 22, 2010 and is now submerged and resting 1,300 feet from the well site on the seabed [1] . The oil leak was discovered Saturday, four days after a explosion and fire. Eleven people of 126 aboard the rig are missing and presumed dead. It is now gushing 42,000 gallons of oil day, about 5,000 feet below the oceans surface [7]. The oil slick is now 600 square miles (1,550 square kilometers),on the surface planes already dropped 7,715 gallons of chemical dispersant and has 100,000 gallons of dispersant ready to be deployed or one third the world’s commodity [3]. There are 32 spill response vessels and 1,000 workers trying to clean the oil slick and as of April 25, 48,324 gallons of oily water had been collected by surface skimmers [2].
BP is currently engineering a system that is shaped like a funnel or large dome that will be lowered underwater to collect the oil that is rising to the surface. This is a new technology that has only been used in shallow waters after Hurricane Katrina and it is not positively going to work because has not been used at such great depths. [4]. “There are currently 4 remote controlled submarines trying to pump fluids into a 450-ton blowout preventer to shut a valve that would close off the well”, according to Doug Suttles, BP’s chief operating officer for exploration and production [2]. If shutting off the valve does not work then BP will try to start drilling a relief well as soon as possible[3]. This would allow other work to permanently seal the well later.
With recent projected increased offshore drilling [6] , how many more oil spills or oil accidents will occur? Although according to a study done by Texas A&M University, the amount of oil split in 2000’s vs. 90’s, 80’s and 70’s has dropped significantly[5], with deeper exploration will there be more environmental damage to come?
