This is shooting in the dark. The existing bend is serving as a constrictor to the flow which means that it is also reducing the high pressures from the ground. If they saw it off and they are not sure if they can work against the increased pressure resulting from the cutting off, then they need to stop and rethink.

Should we mess up a messy situation further?

Experts have said that a bend in the damaged riser likely was restricting the flow of oil somewhat, so slicing it off and installing a new containment valve is risky.

"If they can't get that valve on, things will get much worse," said Philip W. Johnson, an engineering professor at the University of Alabama.

Johnson said he thinks BP can succeed with the valve, but added: "It's a scary proposition."
