"The U.S. official in charge of the federal response to the oil leak in the Gulf of Mexico says BP has made "significant progress" in efforts to stem the flow of crude from a damaged underwater well.
Retired Coast Guard Admiral Thad Allen said on NBC's "Today" show Monday that BP's work could result in the final shutdown of the well, which has been spewing oil since an explosion on a drilling rig killed 11 people in April.
BP says it is making progress installing a new containment cap that could allow ships on the surface to capture virtually all the leaking oil. Company officials expect the new containment system will take four to seven days to install.
The oil company said Monday the leak has already cost it about $3.5 billion. It said the company has paid more than 52,000 damage claims to individuals and businesses, totaling almost $165 million."

"BP Plc may stop the flow of crude from its leaking Gulf of Mexico well, source of the biggest oil spill in U.S. history, beginning with a pressure test today.
BP plans to bolt a 40-foot (12-meter) stack of valves atop the well today and stop the flow for 48 hours as a test, Doug Suttles, chief operating officer for exploration and production, told reporters today on a conference call. If the plan works, the valves will keep oil from leaking until the well can be plugged with cement next month, he said. Should the test fail, BP will resume piping oil to ships on the surface."

"The new cap contains three large valves, or rams, like those used in blowout preventers, which oil and gas drillers use to halt unexpected surges in pressure, Salvin said. The Macondo well’s blowout preventer failed, BP Senior Vice President Kent Wells told a presidential commission investigating the disaster.
The well can be shut if it withstands the expected pressure once the valves on the new cap are closed, Suttles said. Pressure lower than expected would suggest leakage in the well bore, indicating BP should continue to let oil flow to ships on the surface for processing, he said. BP and Obama administration officials will make that decision, he said.
Underwater robots are bolting in place a transitional fitting that was placed atop the well overnight, Suttles said. BP’s “confidence is growing” that it can control the well because installing the fitting gave engineers the “most concern” before starting the job, he said."
