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.
Admiral Allen Directs BP To Complete Relief Well
by Miles Wolf Tamboli - The Talk Radio News Service
On Friday National Incident Commander Admiral Thad Allen issued a directive to BP’s incoming Chief Executive Officer, Bob Dudley, authorizing the corporation to move ahead with efforts to complete the relief well that shows promise of putting a final close on the failed deepwater Macondo well, which was responsible for the months-long oil leak that has put petroleum conglomerate BP in the hot seat since the drilling rig exploded in April.
In the directive, Admiral Allen outlined a number of steps to be executed on the well:
1) Evaluate the status of the well’s casing hammer,
2) Secure the hammer with a locking room, assuming the hangar is in nominal position,
3) Commence completion of drilling by Development Driller III to intercept the Macondo well,
4) Conduct any “supporting activities … that are consistent with the relief well intercept,”
5) Develop and implement procedures that will allow for injection of mud and cement into the well’s annulus (space between the well casing and the earth),
6) Consult the Government Scientific Technical Team if the casing hangar is not in a position allowing for installation of a locking ring.
Although only negligible amounts of oil have leaked into the Gulf since a capping stack was installed on top of the crippled blowout preventer in mid July, Allen has repeatedly stated that, “the relief well remains the ultimate step in stopping the BP oil leak for good.”
