The company that owns the platform, Houston-based Mariner Energy, did not know what caused the explosion.
Earlier reports from the U.S. Coast Guard had suggested that an oily sheen was seen near the site, sparking fears of another oil spill like the BP's Deepwater Horizon Spill, just east of this explosion. A mile-long plume with a width of about 100 feet was reported by the rig's owner, Mariner Energy of Houston.
An oil industry vessel that was nearby plucked the crew members out of the water and brought them to a nearby platform.
Despite years with no major accidents, the offshore oil industry will now be forced to recover from a stigma that it's accident-prone and can't be trusted. BP has a reputation for costly mistakes. Mariner, a smaller independent company based in Houston, also has had numerous run-ins with regulators for safety issues.
