  •  New idea - entomb the BOP (6+ / 0-)

    Taking a page from the Russian response to Chernobyl, I thought this might work...

    1. cut off riser (in progress now)
    1. surround BOP with high pressure cylinder
    1. FILL cylinder with concrete, surrounding BOP
    1. concrete cures
    1. Lower and seal cap on cylinder (cap includes large pressure release valve)
    1. close valve

    This approach eliminates the issues of rupturing the BOP that might happen by a direct capping of the BOP itself, as well as issues with removing the flange off the BOP and fitting a new pipe to the existing flange.

    The an open valve on the 'cap' the cap can be secured without having to deal with the pressure blowing to cap off before it is secured.

    and thoughts why this wouldn't work?

      Just wonder about how much upward pressure there'd be on it, and whether it would hold until the relief wells are done.

    •  That would actually work (4+ / 0-)

      You wouldn't even need the high pressure cylinder. The concrete could have circular rebar embeded as it is poured.

      You will have to change the diameter of the dome cover and make it as small as possible. It needs to withstand 25,000 PSI.

      A 24 inch top would have to withstand 12,000,000 pounds of force. A 12 inch top would have to withstand about 3,000,000 pounds.

      On a lighter note BP already has a similar plan as backup:

      I just found out what BP's next plan is

       

      •  Wouldn't it blow out at the bottom? (4+ / 0-)

        Isn't this just sitting on mud? I imagine covering a spewing tap in my garden with a bucket. Even if I sit on the bucket the water will start oozing out the edges and eventually erode the dirt and come out with as much volume as ever.

          the concrete could possibly lower the possibility of the BOP breaking. With enough concrete, I'd like to think it would hold

        •  Isn't the BOP secured to the well? (1+ / 0-)

          I don;t know the details, but I am sure the BOP isn't just sitting on the hole. It must be bolted to something keeping it on the drill hole. With the cylinder/cap concreted to the BOP, and the BOP secured to the hole, it just might be enough to stop the leak.

          •  The BOP is attached to the feed from (0+ / 0-)

            the well itself -- another three miles down.  But it's been bashed around, is/was off kilter, and got beat to shit when DH went down.  Plus we don't know the integrity of the mud down there at this point.

            They may... we don't.

        •  It would have the entire BOP entombed (0+ / 0-)

          so it would depend on how well the cement was sealed to the BOP's body. BOP has enough protrusions to lock into the main body of the cement.

          Hydraulic cement expands as it cures. But, you'd have to encase everything in a large rubber bag/liner to keep sea water out for a proper cure. This would preclude a good seal.

          Now, the more I think about this plan, the more things occur to me that would make it difficult to achieve.

          •  I wonder if bags of cement (0+ / 0-)

            might work- pour smaller bags (in plastic as you suggest) instead of one large pour into the cylinder.

            I'm just trying to find reasons this couldn't be done. At the rate BP has been going, and with the likely success of the 'relief wells' being in question, I really, really think we need to be looking at plans C, D, E, F, G, H, I, J, K, plan 9, catch 22, and the answer to everything; 42.

    •  wondered that same one myself (3+ / 0-)
      Recommended by:

      Couple things I could see;

      1-Maybe there's not enough 'meat' around the bottom of the bop to get enough concrete to engage to, or that concrete would have to be too heavy in order to do so.

      2- I feel the reason they're doing stuff to capture rather than plug the well is the fear that the whole shebang has become compromised subsurface so that if it were subjected to full pressure it may go..

      Just guesses though.
