What the diamond saw – BP’s latest gambit
CNN’s Josh Levs does a good job explaining BP’s latest plan for its runaway well in the Gulf of Mexico. One error in his presentation – he says the kink in the riser was caused by the initial explosions. It wasn’t. That kink, and indeed the whole clustercuss on the ocean floor, appears to have occurred when the floating rig, the Deepwater Horizon, sank on April 22 – two days after the initial explosions.
The only reason I mention this seemingly minor point is that it may prove much more important as the investigation into the disaster progresses. Some experts believe that the terrible situation was made far worse by the constant stream of water directed at the rig. The weight of the water, they say, caused the rig to collapse and sink, rupturing the pipe.
Updated Update
Reuters is reporting that the diamond wire saw has been freed.
Update on LMRP process
The diamond wire saw used to cut through the Lower Marine Riser Package (LMRP) got stuck while sawing through the riser this afternoon. At last word, BP was still attempting to free it.

Always better to cut “high” on the pipe, leaving some for any mistakes – the jammed diamond blade. And meanwhile, I have read and heard that another well is being drilled to relieve the pressure of the bleeding well. I have not read if the crew is American or British? NPR reported that the ocean floor is a “1000″ feet deep of oozy mud, not stable at all. The cap looks pretty small. It must be tough to jam something into the ocean a mile deep and hit the mark.
