Carnival Liberty

(4:30 a.m. EDT) -- Carnival Cruise Line has been forced to cancel another Carnival Liberty cruise due to on an ongoing issue with a faulty generator which is affecting the ship's propulsion.

The cruise line informed passengers yesterday that today's five-night Western Caribbean cruise out of Galveston had been canceled.

It is the second cruise canceled in a week -- the line was also forced to cancel the ship's five-night Mexico cruise slated to depart on Oct. 31.

All passengers will receive a full refund and any pre-purchased excursions, Fun Shop items and pre-purchased gratuities. Carnival is also applying a 100 percent credit in the amount paid for the canceled cruise on a future cruise purchase.

A statement from Carnival sent to passengers read: "Our technical team, along with outside technical experts, has been working round the clock to fix an issue with one of the ship's diesel generators, which is only affecting the vessel's maximum cruising speed."

"We had hoped to have the issue fixed in time for your sailing tomorrow. Despite our team's best efforts, the work is taking longer than expected. Unfortunately it is now evident we have to cancel tomorrow's cruise."

The next cruise is a four-night Nov. 10 cruise, which has already been affected, calling in at Progreso instead of Cozumel. Passengers booked on this sailing can cancel for a full refund or sail with a $50 per-person onboard credit and 25 percent future cruise discount.

Carnival Liberty, which has been beset by propulsion troubles in the past, cut one of its sailings short by a day earlier this year to allow for repairs. The ship is scheduled for a two-week dry dock on Dec. 1.

We have reached out to Carnival to find out if there are any plans for the ship to go in early.
