A Cameron International executive is questioning theories on why the blowout preventer manufactured by the company failed during BP's accident last year. Norwegian firm Det Norske Veritas's theory is that extreme pressure caused the drill pipe to bend, which prevented the BOP from shutting the blown pipe. However, Cameron's BOP wasn't built to handle such pressure, said David McWhorter, vice president for engineering and quality control, and examiners failed to take other factors into account such as poor maintenance of the BOP.
