13 crew members rescued after another Gulf Coast rig explosion Thirteen members of an offshore oilwell crew were pulled safely from the Gulf Mexico waters after their platform went up in flames just of the Louisiana coast. A fire on a well connected to an oil and gas production platform is out and there is no indication of an oil sheen, the U.S. Coast Guard said.     There were no serious injuries among those rescued. They were wearing survival suits when they were plucked out of the water. There is no evidence of an oil sheen, said U.S. Coast Guard Capt. Peter Troedsson, adding there were no visible leaks. "We continue to investigate and to monitor that situation," he said.  The vessel, the Vermilion Block 380, was engulfed in flames September 2, about 100 miles off the central coast of Louisiana. The fire forced its crew into the water. Louisiana Gov. Bobby Jindal said the crew was doing maintenance when fire broke out.   Jindal said the men he spoke to were in good spirits and one was being released to go home for his son's birthday. "What's important is there are no injuries, no loss of life," Jindal said.   The cause of the fire is not yet known, officials said.   Mariner Energy, which owns the platform, said that the fire was not sparked by an explosion. It started at one of the platform's seven active wells after a safety shutoff occurred, the company said.   David Reed, a paramedic on board a nearby oil rig, said he suddenly saw "a bunch of smoke" from the direction of the Vermilion platform, and radios in his rig's control room started "lighting up like a Christmas tree" soon after. The Coast Guard deployed five helicopters from New Orleans, two from Houston, Texas, and a fixed-wing aircraft from Mobile, Alabama, as well as patrol boats and cutters to the scene.   "Automated shutoff equipment on the platform safely turned off the flow of oil and gas from the platform's seven producing wells before the fire occurred and the crew evacuated," Mariner Energy said in a statement.
