BP replaces preventer

NEW ORLEANS – BP crews worked yesterday to slowly raise the 300-ton blowout preventer that failed to stop oil from spewing into the Gulf of Mexico, careful not to damage or drop a key piece of evidence in the spill investigation.
When the blowout preventer reaches the surface after its mile-long journey, government investigators will take possession of it and eventually examine it, hoping to gain insight into why the device failed.
A BP PLC spokesman said in an email to The Associated Press that the 50-foot device was detached from the wellhead Friday afternoon. Another blowout preventer had successfully been placed on the blown-out well, the government said later. (AP)
