BP cuts pipe, plans to lower cap over Gulf spill

03 June 2010 21:55 (UTC +04:00)

Baku-APA. BP sliced off a pipe with giant shears Thursday in the latest bid to curtail the worst spill in U.S. history, but the cut was jagged and placing a cap over the gusher will now be more challenging, APA reports quoting news.yaho.com website.
BP turned to the shears after a diamond-tipped saw became stuck in the pipe halfway through the job, yet another frustrating delay in the six-week-old Gulf of Mexico spill.
The cap will be lowered and sealed over the leak, said Coast Guard Adm. Thad Allen, the government’s point man for the disaster. It won’t be known how much oil BP can siphon to a tanker on the surface until the cap is fitted, but the irregular cut means it won’t fit as snugly as officials hoped.
"We’ll have to see when we get the containment cap on it just how effective it is," Allen said. "It will be a test and adapt phase as we move ahead, but it’s a significant step forward."
Even if it works, BP engineers expect oil to continue leaking into the ocean.
The next chance to stop the flow won’t come until two relief wells meant to plug the reservoir for good are finished in August.
BP Chief Executive Tony Hayward promised the company would clean up every drop of oil, and "restore the shoreline to its original state."
"We will be here for a very long time. We realize this is just the beginning," Hayward said Thursday.
This 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 removed a kink in the pipe, and could temporarily increase the flow of oil by as much as 20 percent.
Hayward conceded the attempt was risky, but said it was reduced when the pipe was cut away.
Live video footage showed oil spewing uninterrupted out of the top of the blowout preventer, but Allen said it was unclear whether the flow had increased.
"I don’t think we’ll know until the containment cap is seated on there," he said. "We’ll have to wait and see."
President Barack Obama will return to the Louisiana coast Friday to assess the latest efforts, his third trip to the region since the April 20 disaster. It’s also his second visit in a week.
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 $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.
