That said, if the BOP was messed with, more of this will fall on Transocean than we thought. It would not have caused the blowout but would have allowed much of the mess to happen, and I bet the rig insurers will have some say in the pay off.
I have been on lots of offshore rigs, but never a dynamic positioning one. Most of the time a company man would go ashore during a move but would there be enough time on a rig that doesn't have to pick up and set anchors?
The reason I ask is that the BOP would be worked on during moves and BP might have no idea what was done to it.
Just listen to a bit on the Len Wooley(?) radio show about 60 Minutes show, an electrical person on the rig, says BP pushed a faster ROP. They got stuck, had to shoot off, fish and sidetrack.
Looks like the fishing and sidetrack stories might be true, not that I believe 60 Minutes on anything.
