Strong winds parted the cruise ship's moorings in the BAE shipyard, setting her adrift in the Mobile River until assisted by tugs.
One shipyard worker reported missing and is being searched for by Coast Guard Sector Mobile, while one other employee was recovered safely.
The tug New Wednesday was on scene stabilizing the Triumph, and four additional tugboats were en route to assist.
The Coast Guard has issued an Urgent Marine Information Broadcast for mariners to keep a look out for the missing BAE employee on the Mobile River.
Latest reports said the ship was alongside at the Signal International shipyard across from the BAE yard.
The Coast Guard is investigating the cause of the incident.
