Carnival Dream reports problems in St. Maarten

Another Carnival cruise liner is experiencing problems with its propulsion system, power outages and overflowing toilets while docked in the Caribbean, one month after a fire crippled the Carnival Triumph in the Gulf of Mexico.

A U.S. Coast Guard spokeswoman in Miami told the Associated Press Thursday that Carnival Dream's captain reported possible trouble with the ship's propulsion system. Petty Officer Sabrina Laberdesque said the ship has sewage and power and officials are working to correct the problems. She says the Coast Guard is not involved because the ship is moored.

Multiple passengers aboard the Carnival Dream told of the unpleasant unfolding situation while docked in port at Philipsburg, St. Maarten.

"We are not allowed off of the boat despite the fact that we have no way to use the restrooms on board," Jonathan Evans of Reidsville, N.C., said in an email early Thursday. "The cruise director is giving passengers very limited information and tons of empty promises. What was supposed to take an hour has turned into seven-plus hours."

Gregg Stark, who is traveling aboard the 1,004-foot liner with his wife and two children, said "human waste" can be found on the floor of some of the ship's bathrooms and some toilets have overflowed. The ship, which can accommodate up to 3,600 passengers and more than 1,300 crew members, also has mechanical issues.

"The elevators have not been working," Stark told CNN. "They've been turning them on and off, on and off."

Ship officials announced over the liner's public address system that they were trying to fix the problem and were working on the generators. A few hours later, another announcement was made, saying the problem was worse than expected, Stark said.

The Dream had been scheduled to leave port at about 5 p.m. ET Wednesday after sailing from Port Canaveral in Florida on Saturday.

Vance Gulliksen, a Carnival spokesman, told CNN late Wednesday he wasn't aware of a problem. Messages seeking comment early Thursday by were not immediately returned.

A class-action lawsuit has been filed against Carnival Corp. following last month's fire in an engine room that crippled the Carnival Triumph, leaving more than 4,200 passengers without power or working toilets for five days.

A Coast Guard official said a leak in a fuel oil return line caused the fire that disabled the massive 14-story vessel.

Cruise industry expert Andrew Coggins, a former Navy commander who is now a professor at Pace University in New York, said the fire could potentially have been serious.

"The problem is the oil's under pressure," he told the Associated Press. "What happens in the case of a fuel oil leak where you have a fire like that is it leaks in such a way that it sprays out in a mist. In the engine room you have many hot surfaces, so once the mist hits a hot surface it will flash into flame."
