BP got a lot of stick for the Deepwater disaster.  A lot of it is well deserved.  But the report shows there were very serious faults on other companies parts.

Halliburton tested the cement and every test up to when the cement was used suggested the mix was unstable. They didn’t tell BP. Unbelievable.

The Transocean blowout preventer should have kicked in with a deadman system as soon as contact was lost with the surface.  But a flat battery and failty valve caused the deadman system to fail.  The BOP maintenance by Transocean was obviously not carried out properly.

BP did some really bad things as well, for example they didn’t ask Halliburton for positive confirmation of cement tests.  Lets face it, they did most of the bad things and mainly to save time.  

But maybe the demonisation of BP alone at the time was not right.
