BP Robot Seriously Hampers Oil Spill Containment
ChiefMonkeyGrinder writes
"A high-tech effort by BP to slow the oil gushing from its ruptured well head led to a large accident yesterday that forced the company to remove a vital containment cap for 10 hours. Robots, known as remote operated vehicles, were performing multiple operations at the disaster site when one bumped into the 'top hat' cap and damaged one of the vents that removes excess fluid, according to the US Coast Guard. The robots weigh around four tons, and are controlled from vessels on the surface using advanced IT systems with both manual and automated functions. BP removed the cap for nearly 10 hours ... in order to assess it after a discharge of liquids was noted from a key valve. The cap's removal left the oil gushing out of the wellhead, largely uninterrupted. Admiral Thad Allen, US National Incident Commander for the response, told the media that part of the problem was the number of robots conducting simultaneous operations at an immense depth. A dozen robots are circulating the wellhead."
Another factor that may hinder containment even more is the increasing potential for tropical storms in that area of the Gulf.
The chief concern I've heard is that the hurricanes might drive the oil deeper into the wetlands, doing harm to one of the critical ecosystems in the area.
The world's burning. Moped Jesus spotted on I50. Details at 11.
And then the pressure builds up behind the top of the wellhead, forcing oil through the porous sandstone compromising the integrity of the sea bed possibly causing a complete rupture of the ocean floor leading to the entire contents of the oil deposit rushing into the gulf. There's a reason they quit trying to top kill it. There's a reason they removed the broken pipe at the wellhead allowing more oil to flow into the gulf. This is bad, but the alternative is far worse.

I guess the cool part is the robots. The other one appears to be history repeating.
The well casing is ruptured below the sea floor. If they cap it, oil will begin leaking below the surface. This will cause extensive erosion leading to the collapse of the blow out preventor. This erosion will continue and leakage rates will continue to increase until the whole oil field depressurizes. In other words: The very best anybody will ever do is to leave this pipe wide open. It will only get worse from here, and substantially faster if they do cap it. Our only hope is with other means to depressurize this (relief wells).
