The judge plans to hold the trial in at least two phases. The first phase, which could last three months, is designed to determine what caused the blowout and assign percentages of blame to the companies involved. The second phase will determine what efforts the companies made to stop oil from spilling, and how much crude actually spilled into the Gulf.
During opening statements, BP and its partners pointed the finger at each other in a tangle of accusations and counter-accusations, but BP got the worst of it.
Jim Roy, who represents individuals and businesses hurt by the spill, said BP executives applied "huge financial pressure" to "cut costs and rush the job." The project was more than $50 million over budget and behind schedule at the time of the blowout, Roy said.
"BP repeatedly chose speed over safety," Roy said, quoting from a report by an expert who may testify.
Roy said the spill also resulted from Transocean's "woeful" safety culture and failure to properly train its crew. And Roy said Halliburton provided BP with a product that was "poorly designed, not properly tested and was unstable."
Brad Brian, a lawyer for Transocean, said the company had an experienced, well-trained crew on the rig. He said the Transocean workers' worst mistake may have been placing too much trust in the BP supervisors on the rig.
"And they paid for that trust with their lives," Brian said. "They died not because they weren't trained properly. They died because critical information was withheld from them."
A lawyer for Halliburton defended the company's work and tried to pin the blame on BP and Transocean.
"If BP had shut in the well, we would not be here today," Halliburton's Donald Godwin said.
