Reply #6: I would have supposed a compression fitting would do it. [View All]

I realize I'm just guessing and have no idea what the practicalities of doing a repair a mile underwater are.

I figured they could cut off the end of the pipe that was damaged in the explosion to make it regular. Then, slip a compression fitting nut over it. Then the compression fitting. It's like a metal ring that goes around the pipe. Then the top part which would be like a spigot. Install the spigot in the open position so there won't be much pressure until the whole thing is installed. The bottom of the spigot threads into the nut. As it tightens, the compression fitting gets squeezed between them, forming a tight seal on the pipe. When done, turn off the spigot or attach it to some hose or pipe to send the oil to the surface.

Again, just my amatuer impression.
