PENSACOLA, Fla. – The BP oil slick drifted perilously close to the Florida Panhandle’s famous sugar-white beaches Wednesday as a risky gambit to contain the leak by shearing off the well pipe ran into trouble a mile under the sea when the diamond-tipped saw became stuck.
BP engineers will turn to giant shears to slice off the leaking pipe, said Lt. Commander Tony Russell, an aide to Coast Guard Adm. Thad Allen, the government’s point man for the crisis.
The saw had sliced through about half of the pipe when it snagged, and it took BP 12 hours to free it. The company said it hoisted the saw back to the surface after finally yanking it out of the pipe.
The plan is to fit a cap on the blown-out well at the bottom of the Gulf of Mexico to capture most of the spewing oil; the twisted, broken pipe must be sliced first to allow a snug fit. The company had said preparations were being made to resume cutting, but didn’t give a timetable. The shears have already been used to slice off another part of the riser, but crews hoped to use the diamond saw to get a finer cut so they could use a dome that would fit the pipe more snugly.
As the edge of the slick drifted within seven miles of Pensacola’s beaches, emergency workers rushed to link the last in a miles-long chain of booms designed to fend off the oil.
Forecasters said the oil would probably wash up by Friday, threatening a delicate network of islands, bays and white-sand beaches that are a haven for wildlife and a major tourist destination dubbed the Redneck Riviera.
Allen said more staff, boats and helicopters were sent to the eastern Gulf Coast as the slick spread, including a cutter in Mobile Bay, Ala., and one off Pensacola. The boats will help skim oil and add more boom to collect it.
Since the biggest oil spill in U.S. history began to unfold April 20 with an explosion that killed 11 workers aboard an offshore drilling rig, crude has fouled some 125 miles of Louisiana coastline and washed up in Alabama and Mississippi as well. Over the past six weeks, the well has leaked anywhere from 21 million to 45 million gallons by the government’s estimate.
The latest attempt to control the leak is considered risky because slicing away a section of the 20-inch-wide riser could remove kinks in the pipe and temporarily increase the flow of oil by as much as 20 percent.
If the strategy fails – like every other attempt to control the leak 5,000 feet underwater – the best hope is probably a relief well, which is at least two months from completion.
