KENNER, La. -- A Coast Guard worker says he wasn't aware of anyone coordinating efforts to put out a fire on a drilling rig that exploded in the Gulf of Mexico last month.

Kevin Robb, a civilian Coast Guard worker who helped coordinate search and rescue efforts after the blast April 20, made the remarks at a hearing Monday in suburban New Orleans.

When asked whether uncoordinated firefighting efforts could lead to the sinking of a disabled vessel, Robb said that was 'exactly correct.' He said putting out fires out on the water requires a great deal of training and coordination.

Robb said a platform owner may be responsible for enlisting somebody to coordinate firefighting efforts. But he added that he was unsure of who was responsible for coordinating those efforts.
