"BP stands apart, heads and shoulders above all the rest of them, with respect to their conduct," said Coon, who represents a 24-year-old roustabout who was working on the rig at the time of the blast. "It's like they just don't care."
BP issued a release saying it had launched its own investigation into the cause of the blast, and would cooperate with federal efforts.
"Losing 11 of our industry colleagues is a tragedy for the offshore community," said BP Group Chief Executive Tony Hayward in the statement. "As an industry, we must participate fully in these investigations and not rest until the causes of this tragedy are known and measures are taken to see that it never happens again."
