BP Robot Seriously Hampers Oil Spill Containment 264

Posted by Soulskill from the skynet-not-bothering-with-the-sky dept.
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.

  • They need to drop a large (like circus tent sized) funnel over the well head, and have a long wide tube leading up to the surface from there. The oil would rise through the tube, and because it is wide (say 5 metres) it wouldn't get clogged by those methane crystals.

      The problem with making a wide pipe is that it would need to be very thick in order to sustain the pressure difference between a mile high column of oil and a mile high column of water. It would be too heavy to put in place as a result. Also, it's not likely to solve the hydrate problem, since the hydrate crystals would still build up on the inner surface of the pipe. They solved the hydrate problem by preventing seawater to enter the recovery system. A large containment dome would sill allow seawater i

      Isn't that essentially what they're doing with the "cap"? (Except that they can get SOME sealing between it and the wellhead so the pressure will speed the flow of oil up the pipe, reducing the amount escaping around the joint.)

      That's basically what they're doing with the current cap, although it's a bit more complicated than that.

      The blowout preventer is still stitting on top of the wellhead, which prevents them from ramming it down onto the floor. Cutting off the BOP presents another huge series of problems, and probably shouldn't be attempted.

      The primary issue with capturing the oil is the insane amount of pressure at the wellhead. The oil is gushing out of the well, despite there being a mile-high column of water on top of i

    The problem is pressure. There isn't a pumpjack on the sea floor using suction to draw the petroleum out of the well. It is coming out by itself, and under very high pressure.

    You could weld a valve onto the top, but if you try to close it, the pressure will seek relief elsewhere. If you get really, really lucky, it just blows out the weld and rejects the valve. Much more likely, however, it would split the pipe under the sea floor where we don't have access. The only hope of capturing anything is if the breech remains above the surface.

    One day in July or August BP will suddenly get shit under control and the leak will stop over night. That will be the day the two relief wells come online and provide means to reduce the well pressure. BP started drilling these relief wells in April, and they take a few months to come online. Everything else is window dressing.

      Find out how much space would be required for the stuff coming out of the pipe to equalize to the surrounding sea pressure, and how wide of a column of oil and seawater would be heading to the surface. Build a funnel that large, with a tube to the surface. Build them out of heavy plastic film, like the plastic that matresses get wrapped in; a tube wide enough to contain the entire plume at ambient pressure. Lower that over the blow-out and voila, spill contained.

      A 40ft wide roll of black polyethylene plastic sheeting, 100ft long costs $245. for $1500, six of those rolls, heat welded together would form an 80 foot diameter hexagon shaped tube 100 feet long. Fifty of those tubes, end to end would reach the well-head area at a cost of only $75,000. Attach the tube to a giant teepee over the well head area, and one of your parent's siblings is named Robert (Bob's your uncle), the spill is contained.

      Now, polyethylene may not be the best plastic for this. Costs may alter a little bit. You still need to weld the sheets together somehow, and the system needs to be lowered into the water. You may need some stiffeners here and there to maintain the shape of the tube. You'd also need to leave space for the ROVs to get under the teepee to access the well-head. Still, for a measely couple of million dollars, this spill could have been a mere PR hiccup instead of the eco disaster it's turning into.

        That is what the cap is. It is the inlet for a pipe that will siphon some fraction of the oil. You can't make this second pipe a snug fit because of the pressure of the oil coming out. Obstruct the flow and your well pipe may rupture, resulting in a impossible to contain problem (for example, one Slashdotter has speculated that you could end up with a 500 feet wide pit that leaks oil instead of a small pipe).

      Actually, they are planning to put a "capping valve" at the top of the BOP soon, replacing the top hat thingy they have in place now. They are giving very serious consideration to unbolting the flange at the top of the BOP, then bolting a new riser on top.

      Also, they are already collecting oil through from the side of the BOP, via the lines and manifold they were using for the top kill attempt, so even if they did seal the top of the BOP, there would still be some pressure relieved via those lines. However, since BP is not talking about shutting the top of the BOP, they must not believe there is enough pressure relief through the top kill manifold to ensure that the well casing won't fail.

      Here's a quote from a recent conference call by BP:

      "And then – and then in terms of the capping valve, I’ve always told you that we have three options that we’re working. That remains. The – we’re starting to favor the flange-to-flange connection. It brings some advantages in terms of its ability to hold back more pressure. In fact, we believe it has the potential to actually hold the full pressure of the well. However, its challenges are around installation and the teams have been working a lot on all of the different tools and equipment that would be required to do that."

      The relief wells are being drilled so they can pump concrete into the well to plug it. "Relief" doesn't refer to "reducing the well pressure" - it means to relieve the existing well from it's duties.

      The two "relief" wells are targeted to terminate an existing well.

    Hello from 11 miles South of the spill zone.

    We were actually expecting a lot more oil from this news, but the surface is still relatively clear, with small, 20-50 meter blobs of oil to be collected and a great deal of green water otherwise. Two task forces are out here skimming, and 500 bbls a day is a good haul for one of the skimmers. We've been hampered by several fronts passing through the area, but collection continues. There's been a C-130 dropping dispersant in the area, with good results on the oil (although it makes the remains too thin to skim).

    Although many here will scoff at the daily take we're seeing on the skimming vessels, it's surprising how little oil you see around the spill zone. A lot, I hope, is burning in that giant fire in the horizon. I expected a spike in how much oil we'd see, but it's all going... somewhere, just not up here.
