BP: No single factor responsible for Gulf of Mexico spill

No single factor, but decisions made by "multiple companies and work teams" were responsible for the Gulf of Mexico oil disaster, British oil giant BP said Wednesday, DPA reported.

An internal investigation into the leak showed that a "series of "mechanical failures" and "human judgments" led to the explosion of the Deepwater Horizon oil rig on April 20, which killed 11 workers.

The report said BP and other companies involved in the operation "incorrectly accepted" the results of negative pressure tests ahead of the blast.

Mistakes were also made in the use of cement to seal the leaking well, the report said. The rig's blow-out preventer "should have activated automatically to seal the well," said the report.

"But it failed to operate, probably because critical components were not working."
