BP had ultimate authority over drilling decisions, the Deepwater Horizon’s chief mechanic, Doug Brown said in sworn testimony Wednesday.

The BP company man at a meeting stood up and said, “This is how it’s going to be.”

The BP official, a “company man” in industry parlance, would have been the top decision-maker on the rig, although his role may have been complicated by having a number of higher-ranking BP officials on hand to celebrate the Deepwater Horizon’s safety record.

A BP employee named Donald Vidrine, who’s been identified as one of the company men, was on the original witness list for the multi-day hearings, but is no longer scheduled to testify due to an undisclosed medical condition.

The other BP employee on the witness list is Robert Kaluza, who did appear but pleaded the Fifth.

BP refused to identify what role Kaluza and Vidrine had on the Deepwater Horizon.

Michael Williams, a Transocean employee who was chief electronics technician on the rig, said there was “confusion” between those high-ranking officials in an 11 a.m. meeting on the day of the rig blast, according to a sworn statement.

According to Mr. Williams’s account, Transocean’s rig manager, Jimmy Wayne Harrell, was discussing the plans for the next few hours’ work, including taking out the drilling mud and running a test to make sure gas wasn’t seeping into the well. Mr. Harrell explained in the meeting that he had received the plans from BP.

Then, according to Mr. Williams’s statement, the top-ranked BP employee assigned to the rig, Donald Vidrine, disagreed and said “that was not the correct procedure.”
