While all the facts are yet to be disclosed or discovered in about what led up to the explosion of the Deepwater Horizon rig, and the subsequent sinking shows that there was a shocking lack of quality control or even process control. Even though there was a fractured structure with BP contracting with Transocean and Halliburton for work, BP is, as the contract holder, ultimately the final say in how work would proceed. This is clear from the testimony of one of the rig workers who overheard an argument with the BP Offshore Installation Manager and the "Tool Pusher". The argument was over when to remove the heavy drilling mud that is used to control the oil which is under pressure in the undersea reservoir. It seems that the removal of this mud and the failure to react when more was mud was coming out than seawater was going in are likely to be the proximate causes of all that followed, including the massive and on going leak.
