Offshore oil rig explodes in Gulf of Mexico

Grand Isle: An offshore oil rig exploded in the Gulf of Mexico on Thursday, west of the site of the April blast that caused the massive oil spill.

Seven helicopters, two airplanes and four boats were en route to the site, about 80 miles south of Vermilion Bay along the central Louisiana coast.

The Coast Guard said initial reports indicated all 13 crew members from the rig were in the water. One was injured, but there were no deaths.

The platform owned by Mariner Energy is in about 2,500 feet of water, the Coast Guard said, and was not currently producing.

About 206 million gallons of oil from an undersea well spilled into the Gulf after BP's Deepwater Horizon rig exploded April 20, killing 11 workers.
