Tug boats maneuver the Triumph around a dock along the Mobile River in Mobile, Ala., after the vessel had earlier been dislodged by high winds.

MOBILE, Ala. — Authorities were searching for shipyard worker who was thrown into the water in strong winds that also tore a troubled Carnival cruise ship away from the dock at an Alabama port.

Wind gusts near hurricane strength shoved the 900-foot Carnival Triumph free from its mooring Wednesday in downtown Mobile, Ala., where the ship was brought after a five-day ordeal that began when an engine fire stranded it off of Mexico in February. Hours later, four tug boats secured the ship to the cruise terminal.

The crippled cruise ship, whose sewage-filled breakdown in the Gulf of Mexico subjected thousands to horrendous conditions, was being repaired at the dock when it tore loose, lumbered downriver and crunched into a cargo ship.

The violent weather also blew a nearby guard shack into the water. One shipyard worker was rescued and crews were searching for another, a U.S. Coast Guard spokesman said, but the cruise ship’s mishap was unrelated. Coast Guard officials said they saw no sign late Wednesday of the missing employee of BAE Systems, which runs the shipyard.

Authorities are unsure of how deep the water is where the men fell in, but the company’s website mentions its ship-repairing operation is adjacent to a 42-foot, deep-ship channel.

As for the cruise ship, some crew members and workers had been staying on the ship while it was being repaired and people could be seen looking out the windows and on the deck of the ship Wednesday. Carnival said all 600 of its crew members and 200 contractors who were working aboard were safe.
