BP Shrugs Responsibility For Explosion
by Miles Wolf Tamboli - The Talk Radio News Service
In remarks Wednesday after the release of a BP-led investigation into the cause of the Deepwater Horizon explosion in April, BP’s incoming chief executive Bob Dudley said, “the explosion on the Deepwater Horizon was a shared responsibility among many entities.”
These claims come in harsh opposition to BP America Chairman and President Lamar McKay’s earlier statements - “Liability, blame, fault, put it over here … we are the responsible party.”
According to the investigation - which BP funded, led, and published - the ultimate explosion of the Deepwater Horizon rig was the result of a chain of blunders - eight incidents in all.
First, the cement barrier meant to isolate oil from the annulus (the space between the casing pipe and the surrounding rock) failed to isolate the oil. Then, another measure - called “shoe track barriers” - failed to isolate the oil.
Negative-pressure testing was somehow accepted, and crews failed to recognize the influx of oil into the wellbore. Safety mechanisms should have then closed the blowout preventer, but instead the oil-mud mixture was diverted into the mud-gas separator, where the gas was vented directly onto the rig. Although a safety mechanism was designed to then prevent ignition, the fire and gas system failed.
All in all, the blowout preventer was ineffective although three separate methods of launching emergency mode were initiated.
The Leak Is Over: BP, USCG Declare Macondo Well Permanently Sealed

After five months, the BP Deepwater Macondo Well has finally been permanently sealed.
“We can now state, definitively, that the Macondo well poses no continuing threat to the Gulf of Mexico,” said National Incident Commander Admiral Thad Allen in a statement released by the Deepwater Horizon Unified Command on Sunday.
Pressure testing was completed early Sunday morning, assuring crews that the well is in fact completely sealed, and that the cement has set.
“This is a significant milestone in the response to the Deepwater Horizon tragedy and is the final step in a complex and unprecedented subsea operation - finally confirming that this well no longer presents a threat to the Gulf of Mexico,” said Tony Hayward, petroleum mogul BP’s group chief executive, in a press release issued Sunday by BP.
The final plugging of the well was enabled by the drilling of a relief well, which the administration has been touting as the only final answer to the months long leak since the beginning, despite having essentially capped the well with a customized stacking cap in mid July. The relief well intercepted the Macondo’s annulus last wednesday, and began pumping a cement mixture into the open space on Friday.
The deepwater Macondo well, owned and operated by an amalgam of international corporations - including Britain’s BP and Halliburton, and the Swiss company Transocean - spewed millions of barrels of Sweet Louisiana Crude oil into the Gulf of Mexico after the rig exploded in a string of mishaps that took the lives of 11 workers aboard the Deepwater Horizon rig, and crippled the Gulf Coast’s economy, which relies heavily upon the triumvirate of fishing, tourism, and oil industries.
As of Friday, 39,885 square miles of Gulf of Mexico federal waters remain closed to fishing in response to public health and safety concerns, and approximately 600 miles of coastline are still experiencing some oil impacts, primarily in Louisiana, according to the Deepwater Horizon Joint Incident Command.
BP America Chairman and President Lamar McKay said Sunday; “BP remains committed to remedying the harm that the spill caused to the Gulf of Mexico, the Gulf Coast environment, and to the livelihoods of the people across the region.”
