Thank you very
much for your response and for the link (which I have downloaded, printed, and
will read in full).
I realize my
suggestion is very elementary and should have been considered by those in
charge of the project; never-the-less, I would feel very bad if it
turned out that it would have been useful and I didn't say anything about
There is a saying
that if you have a difficult problem and can find no solution you should
consult a "Man From Mars" (please read this as man or woman and adjust the
pronouns appropriately). A "Man From Mars" is a person who is
intelligent but has very little knowledge directly related to the problem and
who, therefore, will have no inhibitions that will prevent him from
considering solutions that may be so simple or obvious that the experts may
actually overlook, ignore, or reject them out of hand.
Regards, and thanks again for the

This is a pretty good piece from TheOilDrum.com:

I have had some thoughts
regarding the catastrophic oil spill in the Gulf of Mexico and I have some
ideas on how to stop it.
I think it should be possible to
make a tool in the form of a large pair of pliers or vice grip that could
simply pinch off the pipe somewhere "above" the well/sea bottom intersection
thereby stopping the leak. Such a tool would require the use of a
submarine to operate the tool and a second submarine using lights and TV
cameras to guide the application. I believe the U.S. Navy could carry
I foresee two problems with this
solution. Perhaps some of you (and I'm thinking of Chris Wright here)
could comment on these problems and/or on anything else you want.
Cracks could form at the ends of
the "pinch" and propagate upstream possibly causing a bigger leak than we
already have. As a solution to this problem I see using a second
tool, or perhaps a second part of the primary pinching tool, that would grip
the pipe upstream of the "pinch" like a pair of pliers to provide a
segment of compressive hoop stress and thereby act as a crack
The above action should stop the
flow of oil but it would also increase the internal pressure upstream of the
"pinch". This increase in pressure could possibly cause a new leak
upstream of the "pinch". I don't have a solution for this
Perhaps some one of you could
forward this (plus any comments it generates) to someone in a position to
take action on the idea.
Best regards to all.
