Michael Bromwich, director of the Bureau of Ocean Energy Management, Regulation and Enforcement, says his agency will work with the Coast Guard to investigate the fire. The oil platform is owned by Houston-based Mariner Energy Inc.
Thursday's fire came less than five months after the explosion of the Deepwater Horizon oil rig that killed 11 people and spurred the worst offshore oil spill in the nation's history.

This time no one was killed and the Coast Guard said no crude was leaking. Coast Guard Captain Peter Troedsson says early reports of a sheen on waters near the platform were inaccurate, "there's no reported evidence of leaks, but we continue to investigate to monitor that situation to make sure that doesn't change."

Troedsson says crews are looking for oil in the water from both air and surface vessels.
