New Orleans, La. – Mariner says the fire was on the upper deck of the two-story platform. The Coast Guard says Mariner initially reported an oil sheen a mile long and 100 feet wide, but the government can't find it. Captain Peter Troedsson says the Coast Guard will use vessels and aircraft to check for leaks. He says he's not sure if oil is leaking underwater from the seven wells connected to the platform.
"That's something that I would rather not speculate on at this point. The company monitors each of those well, and so their data shows that there's no flow through them."
The Mariner platform is in about 340 feet of water 80 miles off the Louisiana coast.
