during cementing operations, they had a pressure surge, the mud column didn't hold, the BOP failed, oil and gas hit the rig floor and was ignited. rig eventually burned up and sank, pipe string is twisted up on the botton. ROVs have been trying and failing to activate the BOP on the sea floor through a tangle of rig debris and pipe.
anybody who thinks BP isn't doing everything money can buy to get this shut in is smoking dope.
Thanks for the explanation. What's BOP? I think I know what ROV---remote operated vehicle is.
