The 2010 spill - Update

The lowering of the big containment dome, alas, was not successful.  Some crystals formed inside it making it unusable.  A second, smaller device seems to have been successfully put in place on one of the smaller leaks:
Efforts to staunch the gusher continued Wednesday. The "top-hat" oil containment device has reached the sea floor and should be in position over the wellhead and operational by the end of the week, BP said.
A larger containment vessel was unsuccessful in stopping the flow of oil from the gusher about 5,000 feet underwater.
BP built the smaller dome after a much larger, four-story containment vessel, designed to cap the larger of two leaks in the well, developed glitches Saturday. Ice-like hydrate crystals formed when gas combined with water and blocked the top of the dome, making it buoyant.
If attempts to cap the well fail, BP may try to plug the leak by shooting debris -- shredded tires, golf balls and similar objects -- under extremely high pressure into the well's blowout preventer in an attempt to clog it and stop the leak. The blowout preventer has been partially successful in sealing the well, but did not fully close when the rig exploded and sank.
Suttles said BP also is drilling a relief well to try to divert the flow to another pipe.
"That started about a week ago," Suttles said. "That work continues. The well is at about 9,000 feet."
It may take up to three months to reach the target area, and progress will slow the deeper the drill bit goes, said David Nagel, executive vice president of BP America.
So now the big dome structure has joined the sunken rig at the bottom of the ocean, which is slowly turning into a dead pool/trash dump:
We might be powerless.
The oil flowing out from the seabed in the Gulf of Mexico may be under such great pressure that we do not possess technology to stop the tragedy. Chances are quite good we have no true sense of the dire nature of the situation. The facts that have been ascertained, however, lead to a dark scenario.
Although BP and Washington are trying very hard to convince the public that everything possible is being done to stem the flow of crude, there is seemingly little that might be accomplished. 5000 feet below the surface of the water with oil blasting out at tens of thousands of PSI, and wreckage from the giant rig scattered about, fixes are not easy to find. The latest plan is for a special funnel to be placed over the spout, which will then force the flow into a pumping channel. But how does a funnel get placed over the top of anything pushing at that kind of pressure? Consider that story to be an unrealistic solution.
A well blowout in 1979 offers a bit of context; except the Deepwater Horizon horror show is already about to transcend what happened in the Bay of Campeche off the coast of Mexico. The Ixtoc 1 rig blew and began to spew crude that flowed uninterrupted for nine months.
The Ixtoc disaster, however, is spit in the ocean compared to the British Petroleum apocalypse. Estimates are the current blowout is putting 200,000 gallons or 5000 barrels of crude per day into the waters of the Gulf. Ixtoc's blowout was not capped until two relief wells were drilled and completed at the end of those nine months, and regardless of optimistic scenarios from the federal government or BP, relieving the pressure on the current flow is probably the only way to stop the polluting release of oil. The only way to relieve that pressure is with additional wells. No one is going to honestly say how much time is needed to drill such wells but consider the scope of environmental damage we are confronting if it requires at least as long as Ixtoc. Nine months of 5000 barrels of crude per day ought to turn the Gulf of Mexico into a lifeless spill pond and set toxins on currents that will carry them to deadly business around the globe.
NOAA apparently believes the situation is on the verge of getting worse. A leaked memo suggests that the tangle of pipes on the ocean floor are covering and constraining two other release points. Pressure is likely to blow those loose and, according to NOAA, the gusher will increase by "orders of magnitude." In most interpretations, that phrase means a ten-fold rise in the flow, which will replicate the Ixtoc disaster in three days.
And there are no guarantees relief wells are the fix. That is a complicated project. They are drilled to intersect the main well and then concrete is forced down the holes to seal the leaking well. What do we do, if that doesn't work? Humans cannot function at 5000 feet of ocean depth and the mitigation efforts currently are being handled by robotic remotes. What is left to us as a solution other than an explosive device, which is often what is deployed during above ground blowouts? Given the pressures reported and the amount of flow, we may need a bunker-buster nuke to be placed over the wellhead. We can then begin to talk about the water pressures caused by burst at detonation and residual radiation. Is that a better or worse situation? Certainly, aquatic life in the Gulf of Mexico is doomed unless there is a reclusive genius to step forward and save us from our great failure.
Anyone who thinks this tragedy is not going to result in massive kills of marine life is either blind, ignorant, or in denial. The one scenario that we all refuse to confront is the possibility that it is beyond our capabilities to stop this undersea blast of oil. If that is the case, the flow continues until the pressure eases, which might be years. How much ecological injury will that cause our planet?
Nobody knows.
Meanwhile, the investigation into this colossal failure is starting to bring to light the ugly truth that a series of equipment failures, lack of oversight and regulation, and bad decisions all combined to cause this catastrophe:
Details of a likely blowout scenario emerged this week for the first time from congressional and administrative hearings. They suggest there were both crew mistakes and equipment breakdowns at key points the day of the explosion.
In the hours leading up to the explosion, workers finished pumping cement into the exploratory well to bolster and seal it against leaks until a later production phase. After the tests that indicated leakage, workers debated the next step and eventually decided to resume work, for reasons that remain unclear.
At the same time, heavy drilling fluid — or mud — was being pumped out of a pipe rising to the surface from the wellhead, further whittling the well's defenses. It was replaced with lighter seawater in preparation for dropping a final blob of cement into the well as a temporary plug for the pipe.
When underground gas surged up uncontrollably through the well, desperate rig workers tried to cap it with a set of supersized emergency cutoff valves known as a blowout preventer. However, the device was leaking hydraulic fluid and missing at least one battery, and one of its valves had been swapped with a useless testing part.
Who in his right mind would think that swapping a security device’s part for a useless piece of junk would be a smart idea?
One of the morons who helped cause this disaster apparently.  It’s on your conscience now.
I hope they make them pay through their teeth for all the damage they are and will be causing and punitive damages on top of that.
