BP Will Try New Option to Plug Oil Leak After Top-Kill Failure Nico Colombant | Washington 30 May 2010 Workers clean up oil residue along the beach in Port Fourchon, Louisiana, 29 May 2010 Photo: AP Workers clean up oil residue along the beach in Port Fourchon, Louisiana, 29 May 2010 Energy company BP says it has failed in its attempt to plug the gushing oil leak on a ruptured well in the Gulf of Mexico. President Barack Obama reacted by saying the situation is in his words "enraging and heartbreaking" and that the U.S. government will not relent until the leak is contained and waters and shores are cleaned up. BP chief operating officer Doug Suttles said the latest maneuver known as a top-kill, which involved pumping heavy fluids and junk into the well, had failed. "After three full days of attempting top-kill, we have been unable to overcome the flow from the well," he said. "So we now believe it is time to move on to the next of our options, which is the LMRP, lower marine riser package cap." The new method involves trying to cut the damaged part of the well and then contain the leak with a valve. Suttles said it would take four days to complete, but he said he could not guarantee success. Officials in the U.S. government estimate between 70 million and 150 million liters of oil have already gushed into the Gulf of Mexico and onto surrounding coastlines in Louisiana since the well's explosion, which also killed 11 workers, on April 20. Other methods BP has tried to stop the crude from causing further environmental damage include a gigantic box placed over the leak and a tube insertion to suck out the oil. Amid public anger, both in affected areas, and on the Internet, as well as harsh media criticism, Suttles admitted he was worried. "This scares everybody, the fact that we cannot make this well stop flowing, or that we have not succeeded in that so far. And we have devoted countless resources, and pulled in the best minds we can find from across the world, and across government, and across industry," he added. "We have tried to tell people since the beginning that we had parallel paths. We are working multiple options in parallel because we did not know which one would be successful." Suttles said the biggest challenge is that the explosion took place 1500 meters underwater, and that none of the maneuvers being attempted have ever been tried so deep. BP is also working on a long-term solution to stop the spill, which involves drilling so-called relief wells, but experts say that process could take up to three more months. The U.S. government has also come under criticism for not doing enough. A representative of the U.S. Coast Guard, Rear Admiral Mary Landry, said she was very disappointed in the top-kill failure. She said the government was working aggressively to stop the effects of the spill. She said about 170 kilometers of coastline had already been contaminated. She also warned the region was entering the new hurricane season, which could further complicate the situation. .
