The investigation found eight major factors that contributed to Macondo well explosion and oil and gas leak. A sequence of failures involving a number of different parties, mainly BP, Transocean and Halliburton, led to the explosion and fire which killed 11 people and caused widespread pollution in the Gulf of Mexico.
BP’s managers and contractors involved with well exploration made mistakes that contributed to the tragedy. In its report BP blamed many of the errors on Transocean Ltd, the owner of Deepwater Horizon rig, and on service provider Halliburton Co.
Bloomberg.Com reports that: “BP’s report concealed the well’s “fatally flawed” design, which “set the stage” for the explosion, Vernier, Switzerland- based Transocean said Sept. 8. The driller, Transocean, cited a series of cost-savings decisions by BP that added risk. Cathy Mann, a spokeswoman for Houston-based Halliburton, said the report had “substantial omissions and inaccuracies” and that BP dictated design and testing procedures for the well.”
