BP No Single Cause
First BP report on Deepwater Horizon explosion sites chain of failures.
BP says it shares the blame for the explosion on the Deepwater Horizon rig that started the worst oil spill in U.S. history.
The company released its internal report this morning.
In the almost 200 page report BP concludes that no single factor was to blame for the explosion, but instead, a series of failures from a number of responsible parties.
The report, based on four months of research from a team led by BP's safety officer outlines failures from cement at the bottom of the well that allowed gas and liquid to flow up the casing to misinterpretation of a pressure test by BP and Transocean, a malfunction by the rig's fire and gas system, and finally, the failure of that crucial blowout preventer on the sea floor.
This morning BP's incoming CEO Bob Dudley said "We have said from the beginning that the explosion on the Deepwater Horizon was a shared responsibility among many entities. This report makes that conclusion even clearer."
Sharing the blame could be key to limiting BP's legal liability for the disaster that killed 11 and leaked more than four million barrels of oil into the Gulf of Mexico.
The company's internal report is far from the final word.
Its release comes as the FBI begins to inspect the failed blowout preventer brought up from the sea-floor over the weekend and now a crucial piece of evidence into the Justice Department's criminal investigation into a disaster the government has promised those responsible will pay for.
