"We are very sorry for this disruption to our guests' vacation plans and extend our sincere apologies. We look forward to welcoming them back on another Carnival cruise," the cruise line said in a statement.
U.S. Coast Guard spokeswoman Sabrina Laberdesque told the Associated Press Thursday that Carnival Dream's captain notified the agency of possible trouble with the ship's propulsion system.
A person claiming to be on the ship posted on the popular Cruise Critic message boards that at 3 a.m., the ship was 10 hours behind schedule. "At first, no toilets or elevators. Those back on but 'mechanical' issues," wrote member herbanrenewal.
In remarks made Tuesday at an annual cruise industry conference in Miami, Carnival CEO Gerry Cahil said the cruise line had started a "comprehensive review of our entire fleet." That review, he said, focused on the prevention, detection and supression of fires; engine room "redundancies;" what hotel facilities might be provided and might run off emergency generators; and what "changes we can make from the first three items and how we implement those."
The Carnival Dream was on a seven-day cruise and is based in Port Canaveral, Fla. The ship was scheduled to call on Nassau, Bahamas; St. Thomas, US Virgin Islands and Phillipsburg, St. Maarten before returning to Port Canaveral.
The 130,000-ton Carnival Dream, launched in 2009, is among the largest ships in the Carnival fleet, and can accommodate 3,652 passengers and 1,369 crew.
