BP Oil took the brunt of blame for the April 20, 2010 explosion and fire aboard the Deepwater Horizon rig, but a federal panel charged with reviewing the disaster said Wednesday there was ample criticism to spread around for the worst oil spill in U.S. history, reports the News Service of Florida. A 212-page report found BP, Haliburton and Transocean all partially to blame for the Macondo well spill that sent 5 million barrels of oil into the Gulf of Mexico during the 87-day ordeal. Faulty materials, inadequate training and lack of oversight were among the major causes for the spill. In a statement BP accepted the conclusions of the report. “BP agrees with the report’s core conclusion consistent with every other official investigation that the Deepwater Horizon accident was the result of multiple causes, involving multiple parties, including Transocean and Halliburton.” BP stock prices were up more than 3 percent during midafternoon trading.
