[Updated at 2:08 p.m.] U.S. Coast Guard Petty Officer Elizabeth Bordelon tells CNN there is a sheen at the site of the production platform that measures approximately 1 mile by 100 feet. This information comes after Gov. Bobby Jindal who said there were reports of a mile-long sheen.

[Updated at 1:03 p.m.] Mariner Energy, owner of the production platform, said in a press release that no hydrocarbon spill has been reported after an initial flyover of the incident.

"Mariner has notified and is working with regulatory authorities in response to this incident," the statement said. "The cause is not known, and an investigation will be undertaken. During the last week of August 2010, production from this facility averaged approximately 9.2 million cubic feet of natural gas per day and 1,400 barrels of oil and condensate."

The company also said no injuries have been reported.

[Updated at 12:48 p.m.] David Reed, a paramedic on board a neighboring oil rig located 14 miles from the platform that exploded, told iReport he saw all thirteen workers rescued from the water.

“We were up here in the radio room and all of sudden we saw a whole bunch of smoke coming from the platform," Reed said. "Shortly after all the radios started lighting up like a Christmas tree. They called any helicopters in the area, any boats in the area to respond, they were saying there were people in the water. There were multiple people in the water.”

[Updated at 12:32 p.m.] White House Press Secretary Robert Gibbs said Thursday that the federal government has "assets ready" to respond to any environmental problems resulting from the explosion of an oil platform off the coast of Louisiana.

[Updated at 12:31 p.m.] All thirteen people aboard a production platform that exploded in the Gulf are accounted for and safely on a commercial vessel according to initial information, the U.S. Coast Guard said in a statement.

"We continue to gather information as we respond with full force, and have oil spill response assets ready for immediate deployment should we receive any reports of pollution," the statement said.

[Updated at 11:53 a.m.] U.S. Coast Guard Petty Officer Bill Colclough tells CNN that 12 people from the production platform are in water immersion suits as they await rescue.

Colclough told CNN there are reports the production platform, which is for both oil and natural gas, is still on fire.

"We don't know what caused the rig to catch on fire," he told CNN, noting the incident is under investigation.

Asked about concerns regarding oil leaks or pollution, Colclough said "there are reports the rig was not actively producing any product, so we don't know if there's any risk of pollution."

Mariner Energy is a leading independent oil and gas exploration and production company in the Gulf of Mexico. About 85 percent of the company's production comes from offshore assets, with a growing share of that coming from deepwater developments.

The explosion comes nearly five months after the Deepwater Horizon drilling rig exploded April 20, killing 11 people and causing oil to gush into

the Gulf of Mexico, leading to one of the worst environmental disasters in U.S. history.

[Updated at 11:43 a.m.] U.S. Coast Guard Petty Officer Bill Colclough tells CNN that all 13 workers involved in the production platform explosion are accounted for, but one person is injured.

Coast Guard Choppers are on the way to the site 80 miles south of Vermilion Bay.

[Posted at 11:33 a.m.] An oil production platform has exploded 80 miles off the coast of Louisiana, with 12 people overboard and one missing, the Coast Guard said Thursday morning.
