    If I had to deploy this idea right now, I would turn to something like these:





    Ship-Launch Rubber Rollers

    Underwater Air-lift Bags-air lift bags, salvage airbags, marine airbag-Evergreen-Maritime ISO17357 Approved

    IMO an inflatable would only be a temporary fix. At best it would slow or stop the flow of oil until the relief wells were operational. These air-bags were not designed for sustained pressure.

    You are correct, but that isn't the only reason. There is some concern that the original BOP was somewhat damaged when the rig sank, and will not be able to handle the full brunt of the capped pressure. This is why they are trying to capture rather than fully cap.

    Or bring a tube down over the end of the spewing pipe. It could also lead up to smaller tubes then into a ship. The kind of tube I'm thinking of is the kind roofers throw debris down that goes right into a dump truck. It doesn't have to be pipe or even leak proof. All its purpose is is to lead the oil some place. Hell, if they could slow this down to 100 barrels a day that would be considered a huge success.

    There must be many ways they can at least try to control the leak until they can stop it.
    This was the idea behind the "dome" and "top hat" projects.

    It worked for a very short time, but methane hydrates quickly clogged the hose leading back up to the ship. Some methane hydrates were expected, but the temperature and pressure variance at these depths produced a greater problem then was hoped for.

    I thought the rig landed about 1500 feet away from the BOP.

    Do you know in what way the BOP is damaged? Are we talking about parts flying of the BOP or the BOP blasting off the base?

    The wreckage did, yes.

    Shortly after the explosion, the fire killed the computer controlling the pods under the rig which were keeping in place. When these pods went off line, the rig was at drift for the couple days it took to sink.

    During those couple days, the rig was pulled as the ocean tides willed. As the tides tried to move the rig, the only thing keeping the rig in the same general aria was the drill string. The BOP acted link an anker.

    As a BOP is not designed to take pulling forces of that magnitude, the BOP was pulled by the rig while it was at drift and while the rig was falling to the sea floor.

    You thought correctly... but the rig didn't need to land on or even close to the BOP to damage it, since while it was sinking it was still connected to the BOP via the riser and drill string. Looking at the 90 degree kink in the 1" thick, 21" diameter riser pipe should give you an idea of the forces there... and that kink is only a foot or two above the BOP.

    I don't... and nobody really does. Hopes were lifted that the BOP is ok during top kill, because the drilling mud they were forcing in raised the internal pressure of the BOP quite a bit. The worry with it though is that it could be internally damaged after the shock from the rig sinking and subsequent massive runaway leak running through it. It just wasn't designed for that, and looking at how the oil stream has been eating away at the kink in the riser raises legitimate concern. With so many working parts in the BOP, and not knowing exactly what the oil path is, there are a lot of variables once a true top cap is placed and the full wellhead pressure comes into play.

    What if it was inflated with a liquid instead of air? Wouldn't that have the same effect of plugging around a pipe as a air filled tube but without the pressure concerns?

    "A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
