Service
In 2001 , the platform was leased to BP for three years, and in July of the same year it arrived in the Gulf of Mexico [3] . Subsequently, the lease term was repeatedly extended, so in 2005 the contract was renewed for a period from September 2005 to September 2010 [4] , later it was renewed again for a period from September 2010 to September 2013 [5] .
In September 2009 , Deepwater Horizon drilled the deepest oil well in history in the Gulf of Mexico near the Tiber field, reaching a depth of 10,680 m, of which 1,259 m was water. [6] [7]
In February 2010, the Deepwater Horizon platform began drilling a well in depth1,500 meters at the Macondo field (Mississippi Canyon block 252) [8] . The license to develop the Macondo field was sold at an auction in March 2008 by BP, subsequently it sold 25% of Anadarko and 10% of MOEX Offshore 2007 LLC (a subsidiary of Mitsui ) [9] .
Death and environmental disaster
The ship was located in the Mississippi Canyon in the central part of the Gulf of Mexico, 84 km southeast of the port of Venice ( Louisiana ), in the process of cementing a well for BP , which did not have time to deliver the well on time.
April 20, 2010 the platform exploded and caught fire.
Despite attempts to extinguish the fire, she sank on April 22 , at a depth of 1,500 m [10] .
At the time of the explosion, there were 126 people on board. 115 people were saved, of which 17 people received injuries of varying severity. 11 people are missing and are considered dead. [11] . The vessel is at the bottom 400 m from the well.
The death of Deepwater Horizon caused a major environmental disaster . It is estimated that up to 5 thousand barrels (about 700 tons) of oil flowed from a sealed well to the surface of the Gulf of Mexico per day (according to other estimates, 100 thousand barrels of oil per day (about 13.5 thousand tons) [12] )
