But what makes the most since to me would just be a huge pipe to guide the flow, until the relief well is done.
You planning on that huge pipe resting on the mud? No way it can hold that kind of weight. Plus, it would tip as it sunk into the mud and would take the BPs out with it.
Props for thinking of it and putting it out there. Don't stop trying. Hell, who knows, we might stumble on something. Even a blind pig finds an acorn every once in a while.

The peice of pipe around the bop would only have to be slightly larger than the bop in diameter. I think a hollow pipe or funnel would weigh less than the 100 ton cofferdam or a not hollow BOP.
How did they get the BOP and cofferdam down there?

The drilling riser and BOP alone push the limits of what these rigs can support. This contraption would weigh enough to sink 10 rigs.
Aren't the risers neutrally buoyant? I would think a larger diameter pipe could be made neutral as well. Obviously, I do not know the limits of these rigs, but it seems this wouldn't be out of reach. Placing a hollow pipe over the leak seems easier than the cofferdam attempt.

The BOP is the size of a large bulldozer. You would need 5,000 feet of casing around 20 feet in diameter.

Unless the steel is floating then no it is not neutrally buoyant. The rig is supporting that weight. That's why they place flotation support around the riser. I've personally seen how much around 5,000 feet of riser and a BOP weight and it was close to 3 million pounds.

That's only a 32 inch piece of pipe. You're talking about something around 20 ft in diameter. There's absolutely no way a floating rig could support that sort of weight.

Again, I realize this is futile as we aren't in the BP board room, and the cofferdam did not work. But thanks for humoring me.
I didn't intend for the pipe to maintain its diameter the whole 5,000 ft. Just wide enough at the base to cover the BOP, or even just the top of the BOP and then reduce in diameter to the size of a normal riser.
Also, what is going to prevent the hydrates from forming with the current solution?

Doesn't matter hydrates hydrates hydrates. Would help with the buoyancy though!

See this is the kind of thing my lack of expertise overlooks. Like I said this is just what makes sense in my head, but clearly, it isn't just that easy to do.

Yeah, it seems like everyone out there has an idea. Like I said a post ago, I realize this is futile, but thanks for humoring me.Posted on 6/2/10 at 12:35 pm to Archie Bengal Bunker
T think they are going to remove the saw???
Posted on 6/2/10 at 12:40 pm to redstick13
What about a collet connector that is used on jumper spools? Couldn't it fit around the flange on the top of the BOP after the pipe is cut. We have fabricated many jumpers with them. It could temporarily hold the new riser on top of the BOP.

Mine were to suction through the choke/kill lines, or not so seriously to pump oxygen/an oxidizer through the choke/kill lines and just light the bitch on fire.

Why can't we just burn this mother again?

If anybody is watching the live can you please explain whats going on right now?
Posted on 6/2/10 at 12:55 pm to the shocker2010
they pulled the saw out
Posted on 6/2/10 at 12:57 pm to jeff967
wonder if they broke the blade?
Posted on 6/2/10 at 12:59 pm to meauxjeaux2
I did not see one still on it
Posted on 6/2/10 at 1:06 pm to redstick13
So - any of our insiders know if they are replacing the saw? How much cut is left on the remaining riser pipe? What is the next step for them down there?

The new riser will have booster lines that will allow circulating glycol or something similar from the bottom of the riser.

Again, everything above the BOP is not rated for a high enough pressure to allow sealing the well. It would create a huge pipe bomb.
