Giant containment box to bottle up oil will head to site of massive Gulf spill

Giant box could be key to bottling Gulf oil spill
PORT FOURCHON, La. — A 12-man crew was making final preparations Wednesday to take a 100-ton contraption 50 miles off the Louisiana coast in an unprecedented attempt to help funnel out oil spewing from the bottom of the Gulf of Mexico.
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 PLC chief operating office Doug Suttles said it would take about two days to put it precisely on the seafloor.
“This hasn’t been done before, it’s very complex and it will likely have challenges along the way,” Suttles said.
The pipes and tubing were to be hooked to a ship over the weekend, and if successful, the oil would eventually be brought to shore. 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 to 11 hours at a speed of 11 knots, or about 13 miles per hour.
Shaffer, who lives in Seward, Alaska, 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.
Rusty Ledet, an operations coordinator for the company that owns the Joe Griffin, was aboard helping out for a few hours before the journey to sea. He was asked whether the device would work. “I guess we’re all going to find out together,” he told The Associated Press.
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.
The vessel is named for a boat captain who worked with company founder Edison Chouest, when Chouest was still in the shrimping business.
Coast Guard Rear Adm. Mary Landry cautioned about high expections for the containment system.
“So, please, I have to manage your expectations and just understand that our job is not done until this well is sealed, until this well is cemented, our job is not done ’til then,” she said.
She also said fires had been lit where the oil is heaviest, near the area of the accident.
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 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.
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.
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 by Monday to start funneling the oil into a tanker.
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.
