Cameron: Don't allow BP to test blowout preventer

NEW ORLEANS – The maker of the blowout preventer that failed to stop last year's Gulf oil spill says oil company BP shouldn't get access to the device to conduct its own testing.

Cameron International says in federal court papers Wednesday that if any more testing is done, a neutral third-party should do it, not one of the defendants in lawsuits over the disaster.

BP requested March 8 to do its own testing to help determine why the blowout preventer didn't work as intended during the April 20 oil rig explosion. The U.S. Chemical Safety Board previously objected to the government's decision to halt its official testing.

Investigators who oversaw the testing in New Orleans have said a report by the firm that conducted the tests is expected to be submitted by Monday.
