Coast Guard investigators from the Coast Guard Marine Safety Center and the Investigations Center of Expertise examine the cruise ship Carnival Triumph's engine room, Feb. 14, 2013, to determine the cause of a fire that broke out Feb. 10 and stranded the ship with its passengers for days in the Gulf of Mexico. The results of the joint international investigation may take months, but could possibly help prevent the same type of incident from happening in the future. (U.S. Coast Guard photo by Lt.
