At a hearing before the Senate Energy and Natural Resources Committee, BP, the well's owner and lead operator of the project, sought to turn attention to Transocean, which had a contract to drill the well for BP using its Deepwater Horizon drill rig.
"Transocean, as owner and operator of the Deepwater Horizon drilling rig, had responsibility for the safety of drilling operations," said Lamar McKay, chairman and president of BP America.
In particular, McKay drew attention to the valve that was supposed to shut off the well in case of an accident. The valve, known as a blowout preventer (BOP), is owned by Transocean.
