Gulf of Mexico: BP to Seal the Oil Leak Spot with 100-ton Cork
A 12-man crew was making final preparations Wednesday to take a 100-ton contraption on a journey to an oil leak site in the Gulf of Mexico in an unprecedented attempt to help funnel out oil spewing from the bottom of the sea about 50 miles off the Louisiana coast.
The giant-concrete-and-steel box is the best short-term solution to bottling up the disastrous oil spill that threatens sealife and livelihoods along the Gulf Coast.
BP spokesman John Curry said it would be deployed on the seabed by Thursday and hooked up to a drill ship over the weekend. The boat, a 280-foot vessel named the Joe Griffin, was expected to start its 100-mile trip around the Mississippi Delta later Wednesday.
The box is the latest idea engineers from oil giant BP PLC are trying after an oil rig the company was operating exploded April 20, killing 11 workers. It sank two days later.
Capt. Demi Shaffer said the trip would take 10-11 hours at a speed of 11 knots, or about 13 miles per hour.
Shaffer, who lives in Seward, Alaska, when he’s not captaining boats in the oilfields, said the ship would wait at the Deepwater Horizon site for the arrival of another vessel with cranes that will lift the containment device and lower it 5,000-feet to the seabed. It’s unclear how long that process would take.
“So far nobody has told us,” Shaffer said.
The Joe Griffin, which also helped fight the rig fire after the Deepwater Horizon exploded, is owned by Edison Choest Offshore and is under contract to BP. It has sleeping quarters and an entertainment room with leather sofas and a big-screen TV.
The vessel is named for a boat captain who worked with company founder Edison Chouest, when Chouest was still in the shrimping business. Griffin later followed Chouest into the oil business and eventually worked his way up to port captain, supervising several vessels at once.
Griffin died in a car accident in 1970. The ship is one of only a few boats that isn’t named for a family member, according to company spokesman Lonnie Thibodeaux.
“Literally it is our latest and greatest supply vessel,” Thibodeaux said.”It just went to work for BP.”
BP is in charge of the cleanup and President Barack Obama and many others have said the company also is responsible for the costs.
BP capped one of three leaks at the well Tuesday night, a step that will not cut the flow of oil but that BP has said will make it easier to help with the gusher.
Two satellite images taken Wednesday morning indicate oil has reached the Mississippi Delta and the Chandeleur Islands off the coast of Louisiana.
It’s not clear whether the oil is on shore, but it’s very close, said Hans Graber, director of the University of Miami’s satellite sensing facility.
U.S. Coast Guard Lt. James McKnight said crews remained at the Chandeleurs on Wednesday after officials got a report of oil coming ashore, but they have not located it.
“They’re sitting there, basically, waiting for the first signs of any kind of a sheen to touch the islands,” he said.
Graber said the images also show oil drifting south, toward the Loop Current, which scientists say could carry it toward Florida and the Florida Keys. The northern edge of the current may have already picked up some oil.
Florida officials fearing tourists will cancel their vacations are trying to quash rumors that oil is already washing up on beaches there.
“We are not two or three days away from it hitting the shore,” said David Halstead, Florida’s emergency management chief.”The beaches are still open.”
The long-term effects of the spill on wildlife are not yet clear. Dead endangered turtles have been washing up on Gulf Coast beaches, but they have no signs of oil and federal fisheries officials are investigating whether aggressive shrimpers may have killed them.
Efforts to stop the oil before it gets to shore picked up Wednesday. Coast Guard crews said they were preparing to corral some and set it on fire, which they last tried April 28. A 28-minute burn then removed thousands of gallons, but weather had not allowed them to do it again. Waves and wind were calm Wednesday.
In Plaquemines Parish, near the southern tip of Louisiana, officials loaded absorbent boom shortly after dawn to take out to the mouth of the Mississippi River. The barge will be used as a distribution point for local fishermen to lay the boom around sensitive marshes.
At a nearby marina, local shrimpers planned to use their boats to put down boom as part of a program BP is running.
The Coast Guard said officials planned to send out about 80 vessels from Biloxi and Pascagoula, Miss., and Orange Beach, Ala., primarily to handle booming. Two Coast Guard cutters would also conduct offshore skimming operations. Crews in Mississippi are picking up debris from beaches to make cleanup easier if oil comes ashore.
In all, about 7,900 people are working to protect the shoreline and wildlife, and some 170 boats are also helping with the cleanup.
A rainbow sheen of oil has reached land in parts of Louisiana, but forecasts showed the oil wasn’t expected to come ashore for at least a couple more days.
“It’s a gift of a little bit of time. I’m not resting,” Coast Guard Rear Adm. Mary Landry said.
In their worst-case scenario, BP executives told members of a congressional committee that up to 2.5 million gallons a day could spill if the leaks worsened, though it would be more like 1.7 million gallons. In an exploration plan filed with the government in February 2009, BP said it could handle a”worst-case scenario” it described as a leak of 6.8 million gallons per day from an uncontrolled blowout.
Containment boxes have never been tried at this depth _ about 5,000 feet _ because of the extreme water pressure. If all goes well, the contraption could be fired up early next week to start funneling the oil into a tanker.
“We don’t know for sure” whether the equipment will work, BP spokesman Bill Salvin said.”What we do know is that we have done extensive engineering and modeling and we believe this gives us the best chance to contain the oil, and that’s very important to us.”
The rig was owned by Transocean Ltd. Some of the surviving workers who were aboard when it exploded are suing that company and BP PLC. In lawsuits filed Tuesday, three workers say they were kept floating at sea for more than 10 hours while the rig burned uncontrollably. They are seeking damages.
Guy Cantwell, a spokesman for Transocean, defended the company’s response, saying 115 workers did get off alive. Two wrongful death suits also have been filed.
While officials worked on cleanup, the long wait took its toll on nerves and incomes.
Perdido Key, a barrier island between Pensacola and the Alabama state line with sugar-white sand studded with condominiums, likely would be the first place in Florida affect by the oil spill. Perdido _ Spanish for”Lost” _ got a sniff Tuesday morning of what may be in store.
“You could smell the smell of it, real heavy petroleum base,” said Steve Owensby, 54, a maintenance man at the Flora-Bama Lounge abutting the state line on the Florida side.
The air cleared later, but Owensby’s 28-year-old daughter, Stephanie, who tends bar at the lounge, said some visitors have complained of feeling ill from the fumes.
“It’s very sad because I grew up out here,” she said.”I remember growing up seeing the white beaches my whole life. Every day I’ve been going to the beach … a lot of people are out watching and crying.”
