New Orleans, La. – The sheen is about one-hundred yards long and about 10 feet wide. It was discovered by a Coast Guard helicopter crew. Surface vessels searching the area hadn't detected any oil. Fire that broke out Thursday morning on the Mariner Energy platform forced 13 workers to jump into the Gulf of Mexico. They were rescued by a supply ship in the area and taken to a nearby platform. No injuries have been reported. Federal investigators from the Bureau of Ocean Energy Management are looking into what triggered the fire. They're also checking to make sure no oil is leaking underneath the platform that sits in about 340 feet of water.
