With the Carnival Triumph and its 4,000 passengers still being towed back to port following an engine room fire earlier this week, the cruise line operator has had to pull the plug on a dozen additional upcoming voyages for the ship.

According to the AP, the canceled voyages were scheduled to take place between Feb. 21 and April 13. Carnival had already nixed two upcoming trips on the troubled vessel.

People who had booked travel on the now-canceled cruises will receive full refunds along with discounts to be used on future Carnival cruises.

The company says passengers will be fully refunded and get discounts on future cruises. Affected passengers will also be reimbursed for non-refundable transportation costs, pre-paid shore excursions, gratuities, and government fees and taxes.

Reports of conditions on board the Triumph are not good, with one passenger using the terms “squalor and disgusting” to describe the situation.

Carnival CEO Gerald Cahill has disputed such reports, saying that “All of our guests are safe, and we’re doing everything we can to make them as comfortable as possible.”

This is the second high-profile disaster for Carnival in the last few years. In the fall of 2010, passengers on board the Carnival Splendor spent several days waiting to be towed back to shore when an engine room fire left the ship stranded in the Pacific Ocean.
