Another mishap involving a Carnival Cruise Lines ship, and this one might end up being the most serious of all. Strong winds apparently caused the Triumph to break free from its mooring in Mobile, Alabama, and Coast Guard crews are searching for a dockworker thought to be missing in the river, reports AP and WKRG. Tug boats apparently have the massive vessel itself back under control, but it was at rest near the dock perpendicular to its original position. The ship also has a gash high up on its stern. The Triumph is the ship that stranded passengers at sea in smelly conditions before being towed into Mobile in February for repairs. Three other Carnival ships also had trouble recently.
