Interviewed by CNN Brian Todd on May 3, BP's CEO for a second time on national television shifted the blame for the accident to Transocean.
Transocean with corporate main offices in Switzarland, Houston Texas and Grand Cayman Island, is the owner operator of the 130 berth Deep Horizon oil rig, which exploded 52 miles southeast of Louisiana in the Gulf of Mexico April 20, resulting in numerous injuries and 11 presumed fatalities.
Of the event, BP CEO Hayward, said it was "clearly a tragic accident." He said his team feels "great grief and sorrow" for the loss of the crew members.
Referring to the blowout preventer, Hayward said the "the ultimate failsafe mechanism ... for whatever reason..... failed to operate."
BP spends $6 million a day on containment flow shut-off efforts, which are proving difficult, involving 1700 people and 70 vessels, he said.
The company keeps using booms to collect the oil, awaits better sea conditions to burn the oil, and is using dispersants to break up the oil.
"We're doing everything we can to contain it in the offshore. A million feet of boom," he said.
"I'm not an oceanographer," he said, when asked whether BP could do the job in preventing the majority of the oil from reaching the near-shore or within sensitive wetlands.
The oil slick as of May 3 had the surface area of Lake Pontchartrain, Mobile Bay and Pensacola Bay, combined.
To a lawsuit filed by families of the missing crewmen he said; "The responsibiloty for safety is with Transocean....the systems process is the accountability is with the drilling company."
In this report by Al Jezeera Enlgish Network, Hayward indicates that for the first time in the history of the industry dispersal is being applied to the spill as it is coming out of the pipe, at depth. This has a significant impact, he said, on the spill.
He offered no explanation as to how he knows this, in that the point source of the flow is 5,000 feet below the surface.
