A federal official says the firm hired to test a key piece of equipment to determine why it didn't stop last year's Gulf of Mexico oil spill has submitted its results to government investigators.
The official spoke Monday to The Associated Press on condition of anonymity because the person was not authorized to disclose the information publicly. The official says the government is reviewing results of the blowout preventer tests and may release them later this week.
Blowout preventers sit at the wellhead of exploratory wells and are supposed to lock in place to prevent a spill in case of an explosion.
The 300-ton device that was used with BP's Macondo well was raised from the seafloor Sept 4. Testing began at a NASA facility in New Orleans in November.
