Cameron International, the company the built and owned the failed blowout preventor (BOP) used on the ill-fated Deepwater Horizon oil rig, said its device did not cause the April 2010 disaster that caused the BP oil spill in the Gulf of Mexico. Attorneys for Cameron filed a motion to dismiss the personal injury and death claims brought forth in one of the pleading bundles in the Federal multidistrict litigation (MDL) surrounding the oil spill. The motion cites findings by the U.S. Presidential Commission on the BP Oil Spill, which state that hydrocarbons had begun moving up the well to the oil rig before workers on the Deepwater Horizon were able to activate the BOP. "Even a perfectly functioning BOP could not have prevented the explosions," the motion says. [also refers to Det Norske Veritas]
