Search widens for oil platform worker missing after explosion Searchers in the Gulf of Mexico say they've found the body of one of the two people who went missing after an oil platform explosion on Friday. The owner of an oil platform that caught fire after an explosion in the Gulf of Mexico last week said Sunday that it has expanded its search for a missing worker, and doctors said one of four men burned in the blaze is improving and is now in fair condition. Two remained in critical condition and one in serious condition, doctors said. Three dive boats are now working around the burned platform and Plaquemines Parish sheriff's deputies are checking beaches, Black Elk Energy of Houston said in a statement emailed Sunday evening. It said all helicopter companies flying in the area have been asked to keep an eye out, and a search-and-rescue dog will be brought to the platform Monday. The body of a second missing worker was found Saturday and turned over to the Jefferson Parish coroner, added the company, which said it is cooperating with investigators. "We remain focused on the victims and their families, including those injured," the statement said. 'I am alive' At Baton Rouge General Medical Center's burn unit, Wilberto Ilagan, 50, of the Philippines, told Dr. Jeffrey Littleton that he wanted to send a message, according to a news release issued Sunday. "To my relatives, to my family, and to my country, I am alive and in good health," Ilagan said. I am burned, but my heart and lungs are healthy. According to The Advocate, Littleton said Sunday that the other men's names are being withheld because they have not given their consent to release them. The Philippine Embassy in Washington has said all the workers are from the Philippines. Body found at scene of oil platform explosion in Gulf of Mexico, Coast Guard says The Coast Guard has suspended its own search after checking 1,400 square miles near the oil platform, located about 20 miles southeast of Grand Isle, La. John Hoffman, the president and CEO of Black Elk Energy, said in an earlier statement that the body was found near where the explosion occurred. The dead, missing and wounded workers were employees of oilfield contractor Grand Isle Shipyard, he said. An explosion and fire on Friday severely damaged an oil rig in the Gulf of Mexico, about 25 miles southeast of Grand Isle, La. Cause of fire unknown GIS CEO Mark Pregeant released a statement that the company has notified the families of those involved but was not releasing their names, WWL-TV in New Orleans reported. Authorities have said the blaze erupted Friday morning while workers were using a torch to cut an oil line on the platform. Pregeant's statement, however, said the cause of the fire and explosion is unknown and that "initial reports that a welding torch was being used at the time of the incident or that an incorrect line was cut are completely inaccurate." Eleven people were injured in the production platform blast and oil spillage was minimal, according to the Coast Guard. A man who answered the phone at the company's Galliano, La., office on Sunday said the company had no comment. Coast Guard searches for 2 missing after Gulf oil rig blast Lawsuit Separate from the explosion, Grand Isle Shipyard is facing a lawsuit by a group of former workers from the Philippines who claim they were confined to cramped living quarters and forced to work long hours for substandard pay. The lawsuit was filed in late 2011 in a Louisiana federal court and is pending. Lawyers for the company have said the workers' claims are false and should be dismissed. The workers recently obtained conditional class certification for allegations that Grand Isle Shipyard didn't pay them properly for overtime and may have violated other fair-labor standards, said attorney Joseph C. Peiffer. He said a notice will go out soon to let other workers know they might be able to join the lawsuit. He said he was not representing the injured workers, but didn't rule out the possibility that he might do so. Meanwhile, Black Elk said no oil was leaking from the charred platform, which hadn't been operating since August.
