Why did the BOP fail on Deepwater Horizon?
The CSB concluded that the blowout preventer (BOP) failed because miswired control systems would have prevented it from sealing the blown-out well. A blowout preventer is a multi-ton stack of valves and pipes that sits atop deepwater wells to stop oil and gas from gushing upward in an accident.
Who investigated Deepwater Horizon?
In September 2011, BOEMRE and the Coast Guard published its final investigative report on the accident. In essence, that report states that the main cause was the defective cement job, and Halliburton, BP and Transocean were, in different ways, responsible for the accident. The report consists of two volumes.
How accurate is Deepwater Horizon?

What was the CSB investigation into Deepwater Horizon?

Where is the Deepwater Horizon BOP stack?
The Deepwater Horizon BOP stack at NASA-Michoud (with the upper LMRP portion on left) This analysis considered the BOP examinations that were conducted by Det Norske Veritas (DNV) at the NASA Michoud facility near New Orleans, Louisiana.
Did the Deepwater Horizon BOP close on April 20?
Despite the multiple maintenance problems found in the Deepwater Horizon BOP, which could have been detected prior to the accident, CSB investigators ultimately concluded the blind shear ram likely did close on the night of April 20, and the drill pipe could have been successfully sealed but for the buckling of the pipe.
What went wrong on the Deepwater Horizon?
The final set of failures on April 20 involved the Deepwater Horizon ’s blowout preventer (BOP), a large and complex device on the sea floor that was connected to the rig nearly a mile above on the sea surface.
