On April 20th, 2010 the Deepwater Horizon oil rig located in the Gulf of Mexico, suffered a massive explosion resulting in history’s largest marine oil spill to date. The explosion resulted in an estimated 1,770 kilometers of shoreline being polluted as well as the sinking of the oil rig on April 22nd, 2010 (Pallardy 2015).
Transocean, an off-shore drilling company, owned and operated the Deepwater Horizon oil rig, which was leased by British Petroleum (BP). On the night of the explosion a concrete core installed by a company called Halliburton, used to seal the well for later use was ruptured by a surge of natural gas. The gas traveled up the rig’s riser to the platform where it ignited, resulting in the death of 11 employees and the severe injury of 17 others. When the rig sank it caused the riser to rupture. Drilling mud had been injected into the riser to counteract the upward pressure of the natural gas and oil. Unfortunately as a result of the riser rupturing, the lack of opposing force caused oil to begin spilling into the gulf. British Petroleum estimated the spill to be leaking approximately 1,000 barrels per day, whereas United States government officials estimated approximately 60,000 barrels per day (Pallardy 2015).
