Following a setback Saturday in its tube strategy to contain the flow of oil in the Gulf, BP was giving it another shot on Sunday.
Natural gas was siphoned out Saturday and then burned off when it got to the surface. Oil also entered the tube but a glitch stopped the strategy before any oil could make it all the way to the surface.
“The concept can now be considered proven,” a source close to the operation said shortly before BP said a new attempt was under way.
The fix involves guiding undersea robots to insert a 4-inch tube into a 21-inch pipe, known as a riser, to funnel the oil to a ship at the surface.
BP said Saturday it was confident its latest experiment using the mile-long tube would capture much of the oil flowing into the Gulf of Mexico.
