METAIRIE, La. — BP used giant shears to slice off a pipe Thursday in the company’s latest bid to contain the Gulf of Mexico oil, but the cut was irregular and placing a cap over the gusher will now be more challenging, Coast Guard Adm. Thad Allen said.
BP had to use the shears after a diamond-tipped saw became stuck in the pipe halfway through the job, yet another frustrating delay in six weeks of failed efforts to stop, or at least curtail, the worst oil spill in U.S. history.
Allen said the cap was over the spill and will be lowered in the next couple of hours. It won’t be known how much oil BP can siphon to the surface until the cap is fitted, but the irregular cut means that the fit won’t be as snug as officials had hoped.
The next chance for stopping the flow won’t come until two relief wells meant to plug the reservoir for good are finished in August.
BP’s top executive acknowledged Thursday the global oil giant was unprepared to fight a catastrophic deepwater oil spill. Chief executive Tony Hayward told The Financial Times it was “an entirely fair criticism” to say the company had not been fully prepared for a deepwater oil leak. Hayward called it “low-probability, high-impact” accident.
“What is undoubtedly true is that we did not have the tools you would want in your tool-kit,” Hayward said in an interview published in Thursday’s edition of the London-based newspaper.
The latest attempt to control the spill, the so-called cut-and-cap method, 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 per cent. Allen said it was unclear whether the flow had increased.
Oil drifted six miles from the Florida Panhandle’s popular sugar-white beaches, and crews on the mainland were doing everything possible to limit the catastrophe.
The Coast Guard’s Allen directed BP to pay for five additional sand barrier projects in Louisiana. BP said Thursday the project will cost it about US$360 million, on top of about $990 million it had spent on response and clean up, grants to four Gulf coast states and claims from people and companies hurt by the spill.
As the edge of the slick drifted toward Pensacola’s beaches, emergency workers rushed to link the last in a miles-long chain of booms designed to fend off the oil. They were slowed by thunderstorms and wind before the weather cleared in the afternoon.
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.
“We are doing what we can do, but we cannot change what has happened,” said John Dosh, emergency director for Escambia County, which includes Pensacola.
The effect on wildlife has grown, too.
The U.S. Fish and Wildlife Service reported 522 dead birds — at least 38 of them oiled — along the Gulf coast states, and more than 80 oiled birds have been rescued. It’s not clear exactly how many of the deaths can be attributed to the spill.
Dead birds and animals found during spills are kept as evidence in locked freezers until investigations and damage assessments are complete, according to Teri Frady, a spokeswoman for the National Oceanographic and Atmospheric Administration.
“This includes strict chain-of-custody procedures and long-term locked storage until the investigative and damage assessment phases of the spill are complete,” she wrote in an email.
As the oil drifted closer to Florida, beachgoers in Pensacola waded into the gentle waves, cast fishing lines and sunbathed, even as a two-man crew took water samples. One of the men said they were hired by BP to collect samples to be analyzed for tar and other pollutants.
A few metres away, Martha Feinstein, 65, of Milton, Fla., pondered the fate of the beach she has been visiting for years. “You sit on the edge of your seat and you wonder where it’s going,” she said. “It’s the saddest thing.”
Officials said the slick sighted offshore consisted in part of “tar mats” about 152 metres by 609 metres in size.
County officials set up the booms to block oil from reaching inland waterways but planned to leave beaches unprotected because they are too difficult to defend against the action of the waves and because they are easier to clean up.
“It’s inevitable that we will see it on the beaches,” said Keith Wilkins, deputy chief of neighbourhood and community services for Escambia County.
