Robots aim to plug Gulf oil leak with small tube
Company engineers were trying to move the six-inch tube into the leaking 21-inch pipe, known as the riser. The smaller tube will be surrounded by a stopper to keep oil from leaking into the sea. BP said it hoped to know late last night if the tube succeeds in siphoning the oil to a tanker at the surface.
Since an April 20 drilling rig explosion set off the catastrophic spill, BP has tried several ideas to plug the leak that is spewing at least 210,000 gallons of oil into the Gulf a day. The size of the undulating spill was about 3,650 square miles, or the size of Delaware and Rhode Island combined, said Hans Graber, director of the University of Miami’s Centre for Southeastern Tropical Advanced Remote Sensing.
