It's like i said in the other thread - do you think people drill holes in the seabed for fun?
The BOP failed, that is all on transocean - but it's got so big now, of course the buck will ultimately stop with BP, but bp will hammer transocean over this. It's transoceans fault, but a BP lease block, so they are responsible for the oil and all the costs that go with cleaning up, reimbursing industry etc etc. They'll pay for everything - they're being very transparent, it's a fucking bad situation as well... worse then all of you know; this is pretty much like the Kuwait wells, only 5000ft down, which has NEVER happened before, there has never been an uncontrolled blowout subsea before, not deepwater... so everything being done is an industry first. THe layers of protection involved (LOPA) are more then sufficient, but multiple failures, common cause failures and human error (plus unfortunate things that happened, e.g the pipe rack handling system being blown across the rig into the accommodation taking out the toolpushers office (where another EDS/shut down button is). See those pictures - notice the hole in the heli deck? the ROV shack was driven through it by the force of the explosion apparently....
