Lodged Pipe Led To Blowout Preventer Failure

A study released by the Interior Department and U.S. Coast Guard says a piece of pipe on the Macondo well became stuck following the blast that ravaged the Deepwater Horizon rig and once the pipe was lodged, blades could not cut it, resulting in the flow of oil and gas to the surface of the Gulf of Mexico and the largest spill in U.S. history.

BP (BP), Europe's second-largest oil company and the operator of the Macondo well project, said it is reviewing the report's details, but not openly dispute them. The blades that attempted to cut the pipe were part of the failed blowout preventer manufactured by Cameron International (CAM).

The failure of the blowout preventer has been a central aspect to investigations by the government agencies investigating the explosion of the Deepwater Horizon rig. Testing conducted on the blowout preventer conducted at a NASA test facility concluded earlier this month, Bloomberg News reported.

The report released today recommends the drilling industry examine ways to keep pipes from buckling inside the blowout preventer in the case of a loss of well control and shears be redesigned to cut through pipes in all situations, according to Bloomberg. Transocean (RIG), the world's largest provider of offshore drilling services, was the owner of the Deepwater Horizon.
