Robot submarines are carrying equipment and cutting small pipes at the bottom of the Gulf of Mexico, preparing to place a cap-like containment valve over the blown-out oil well.
Video feeds Monday showed the robots using a circular-saw-like device to cut small pipes. BP crews are readying their latest bid — the cut-and-cap — to contain the leaking well.
BP spokesman John Curry says crews will eventually cut the leaking riser and place the cap on top of it. The company says if successful, the cap could contain the majority of the spewing oil and bring it to the surface.
The company could launch the mission as early as Wednesday.
Millions of gallons of oil have already leaked in the nation's worst oil spill.
