April 27 (Bloomberg) -- BP Plc intensified efforts to stop an underwater well leak that was streaming oil 80 miles (129 kilometers) across the Gulf of Mexico, menacing the shoreline and triggering the evacuation of a drilling rig 10 miles away.
BP increased the pressure on Hydraulic Valves on the seafloor to halt the oil leak, U.S. Coast Guard Petty Officer Erik Swanson said today in an interview. BP, which leased the rig from Geneva-based Transocean Ltd., has said the next quickest alternative to curbing the spill may take two weeks.
Winds that scattered the slick northward have reversed and eased and are now ¡°in our favor,¡± reducing the risk that oil will hit shore, Swanson said.
BP Chief Executive Officer Tony Hayward, who flew to the U.S. to oversee the cleanup, has promised to do ¡°everything in our power to contain this oil spill.¡± The London-based company said today profit more than doubled in the first quarter on higher oil prices and improved refining margins.
Oil is escaping the well near the rig at an estimated rate of about 1,000 barrels a day. The Deepwater Horizon rig sank April 22 after an explosion and fire that burned more than 24 hours. The incident left 11 of the 126-member crew missing and feared dead.
Vessels equipped for corralling oil with floating barriers and skimming it from the surface are expected to resume work today at first light, Swanson said.
¡®No Shoreline Impact¡¯
¡°We have no shoreline impact at this time,¡± U.S. Coast Guard Rear Admiral Mary Landry, the government coordinator of the spill response, said of the oil spill at a press conference yesterday. ¡°Our goal is to continue to fight this spill as far offshore as possible.¡±
BP began building an underwater dome to collect the oil near the seafloor, which may take two weeks to put in place, Doug Suttles, BP¡¯s chief operating officer for exploration and production, said at yesterday¡¯s press conference in Robert, Louisiana.
The company intends to drill at least two additional wells extending 18,000 feet below the seafloor to permanently stop the leakage. That may take three months, BP said. The first drilling rig has arrived at the site, Swanson said.
About 97 percent of the oil slick is so thin that sunlight passes through it and reflects back off the water, creating an optical effect called a ¡°rainbow sheen,¡± Charles Henry, a National Oceanic and Atmospheric Administration forecaster, said yesterday. Most of that oil will evaporate, Hydraulic Pressure Control Valves so oil-removal vessels hired by BP are concentrating on areas where waves have whipped oil and water into thicker patches, he said.
Other Rig Evacuated
The crew of the Ocean Endeavor, a drilling rig owned by Houston-based Diamond Offshore Drilling Inc., was evacuated from ¡°an abundance of caution¡± to avoid a risk of fire from the sheen, Les Van Dyke, a spokesman for Diamond Offshore, said yesterday in an interview. The rig, which wasn¡¯t producing oil, is moored to the seafloor and remains in place, he said.
Exxon Mobil Corp., which was subleasing the rig from Devon Energy Corp., agreed to evacuate the rig, Van Dyke said.
Shutting the underwater valves at BP¡¯s Macondo well is the quickest route to ending spillage, Suttles said. The cause of the explosion and the reason valves at the seafloor didn¡¯t shut automatically aren¡¯t known, Suttles said.
The rig sank with 700,000 gallons of diesel fuel on board, and none is leaking, based on observations by a remote-operated vehicle, according to the Coast Guard¡¯s Landry.
Better Weather
BP said in a statement yesterday it was accelerating efforts because of improving weather conditions, including dispatching 10 boats to corral oil in floating barriers and skim it from the surface.
Better weather ¡°combined with the light, thin oil we are dealing with has further increased our confidence that we can tackle this spill offshore,¡± Hayward said in the statement.
More than 1,000 people are taking part in the oil-spill response, the company said.
The Coast Guard on April 23 suspended its search for 11 workers missing after the rig exploded and caught fire. It was the deadliest U.S. offshore rig explosion since 1968, when 11 died and 20 were injured at a platform owned by Gulf Oil Corp., according to data from the Minerals Management Modular pressure relief valves Service.
BP¡¯s Hayward has spent his first three years in charge trying to restore the company¡¯s reputation for safety following a fatal explosion at the Texas City, Texas, refinery in 2005. The rig accident may cost insurers and reinsurers $1.6 billion, according to an estimate by JPMorgan Chase & Co.
The Exxon Valdez tanker spilled about 260,000 barrels of crude oil in Prince William Sound, Alaska.
