MOBILE, AL (NBC) -- The Carnival Triumph -- the cruise ship that lost propulsion in the Gulf of Mexico in February, eventually leaving thousands of passengers stranded aboard with backed up toilets and limited food -- broke loose from its moorings at a shipyard in Mobile, Ala.

"Due to strong winds in Mobile, Ala., Carnival Triumph, which was docked at a Mobile shipyard, broke away from its moorings," Carnival said in a statement. "The ship drifted and is currently resting against a cargo vessel. Tug boats and the U.S. Coast Guard are on site."

The ship drifted and struck a moored Army Corp boat, the Coast Guard said. No one on that vessel was hurt.

The Triumph suffered a scrape on its side from the collision, and hit a dock as it was drifting, the Coast Guard said.

The Triumph is being controlled by harbor tugs, said Judith Adams of the Alabama Port Authority.

A guard shack two docks over from the Triumph blew over when the ship broke loose, Mobile Fire-Rescue told NBC News. One person has been pulled from the water and is currently in the hospital. Mobile Fire-Rescue is searching for a second person.
