A team of scientific experts has faulted BP, its contractors, and government officials for missteps that led to the Gulf of Mexico oil spill. In a preliminary report, a 15-member committee from the National Academy of Engineering says BP’s “insufficient consideration of risk” and “lack of operating discipline” contributed to the largest offshore oil spill in U.S. history. The report also criticizes the U.S. Minerals Management Service, the government agency responsible for overseeing offshore drilling, for “insufficient checks and balances for decisions” on well safety. Overall, the report says regulation of oil drilling has been “relatively minimal” compared to other high-risk industries.
