The National Oil Spill Commission released Thursday a lengthy report from its chief counsel that concludes the blowout preventer at BP’s Macondo well was not “the root cause” of the accident that killed 11 people and sent millions of barrels of oil into the Gulf last year.
The report, from Chief Counsel Fred Bartlit, is the commission’s strongest statement yet that the BOP, which many have said was the key piece of evidence in the accident investigation, was not to blame. Bartlit said that while the BOP’s performance was “flawed,” it did not cause the blowout.
“Even if the BOP had functioned flawlessly, the rig would have exploded and 11 men would have died,” the report’s executive summary said.
The new report also claims that BP knew of critical problems with the well design and the design of the cement job by Halliburton, but failed to address them.
Republicans in Congress, and some Gulf Coast Democrats, severely criticized the commission’s final report, saying that it was incomplete because investigators had not physically examined the BOP, a five-story series of valves designed to seal a well in an emergency. The BOP is undergoing a forensic examination in Louisiana as part of a joint investigation being conducted by the Bureau of Ocean Energy Management, Regulation and Enforcement and the US Coast Guard.
At a hearing on January 26, congressmen blasted commission co-chairs William Reilly and Bob Graham, saying that their report did not find the cause of the accident and that no conclusions could be drawn about a cause until the examination of the BOP is complete.
Bartlit’s report also concluded that BP’s internal documents show it had problems with the Halliburton engineer assigned to Macondo “for years.”
“But they neither reviewed his work at Macondo carefully, nor even checked to see that he conducted testing in a timely manner–even though they knew that their last-minute changes to the cement design test could cause problems and that using nitrogen foamed cement could pose ‘significant stability challenges,'” the report stated.
Bartlit also said in the report that once the commission identified “serious concerns” with the Halliburton design for the cement job, the company stopped cooperating with the investigation.
“Halliburton refused to allow the team to conduct further interviews of its cementing engineer and lab personnel,” the report stated. “Halliburton has not provided scientific data to support some of its technical assertions, and declined to provide documents regarding lab-testing protocols and evaluation criteria.”
A Halliburton spokeswoman did not immediately respond to a request for comment.
They had been looking at the wrong BOP switched in May. First they get the media to focus intensely on the BOP. Now they say it is not the root cause. Of course the root cause is never that simple …. the underlying greed and power play.
In his comment (about four or five above this one, Lorne White is crecort in saying that the Niagara Falls, New York wastewater treatment plant crashed in the late 1970s when its carbon bed system, included to filter out the contaminants from nearby chemical corporations (i.e. Olin and Hooker along Buffalo Avenue, caved in not too long after they were installed. We then endured about four or five years of effluents from these industries and others discharging to the river without appropriate treatment while the city argued with the state and federal governments over who should pay for the repair of the carbon system. I would have to recover the logs from my old file boxes to recall the details of the settlement, but the carbon filtration system was eventually fixed.That does necessarily mean that the effluent that is run through them is free of contaminants upon discharge to the Niagara River. It also does not help us answer key questions like: What are the chemicals in this fracking wastewater so that they may be monitored at point of discharge and for any trace of them further down the river and in to Lake Ontario?, and what are their potential impacts on wildlife and a foodchain up to and including humans in the lower Great Lakes basin? Until those questions are adequately addressed, any plan to use this Niagara Falls wastewater facility as a dumping zone for chemically laced fracking wastes should be frozen.Doug Draper, publisher, Niagara At Large.
