Not lost at all.... History has been made and it won't shine to favorably on the sitting government.
How big is this "hole". At the risk of sounding ignorant, I'm going to ask why they just can't drop a huge cast iron "lid" over it?
That would be extremely temporary. It would last until the oil oozed out throught the uneven parts of the pipe and wormed its way out from under your lid.
As Anna posted a while back, I am pretty sure that sending a balloon down inside the pipe and inflating it with seawater would work like a charm. Think about it: push on the end of an inflated balloon and watch what happens to the sides of the balloon. The more the oil pushes on the end of the balloon in the pipe, the more the balloon's sides want to expand but the pipe restricts it from doing that.
We use balloons in the fire dept. for a variety of things like expanding crushed car parts to make space when portapowers (jaws of life) couldn't access them. We also use them to lift heavy objects from lake beds. So they are built from pretty tough materials.
The toughest thing to this would be connecting a mile of decent strength waterhose together and figuring out how much pressure is needed to inflate the balloon and keep it in place.
When everything's ready they could dive again with a cap and cap the pipe at their leisure.
Thats right,the oilsands are confined to one area and can be reclaimed,that oilspill cant.The company I work for specializes in diving in those environments and that kind of work and they say it doesnt look good for BP,not much can be done and it will get worse yet.
The biggest problem is it's so deep down that the only way to do anything is with robotics,someone obviuously didnt do their due dilligence and i'm sure they will be made an example of.Too bad the environment will pay no matter what.
Yep. A mile is a ways down.
It could be worse though, they could have had to deal with wave action if it were closer to the surface.
