An oil production platform in the Vermilion Bay exploded today around 9:30am, with 13 people on board. One crew member was injured, and 12 are in the water in immersion suits. As of 10:30am the rig was still on fire.
The Coast Guard is now on dealing with the emergency and has dispatched helicopters and ships to the platform. Vermilion 398, owned by Mariner Energy, is not a drilling rig but an oil "fixed, manned production platform." [USA Today]
