A Carnival Cruise Line spokeswoman said there are no issues from a speed standpoint in terms of operating the current itinerary.
She had no word on the official cause of the fire, which broke out Sept. 7 when Carnival Liberty was alongside at Charlotte Amalie. The ship's automated suppression systems extinguished the fire, and there were no injuries.
Carnival Liberty had remained in St. Thomas until Thursday night, when it was cleared to sail by authorities including the US Coast Guard. About 1,500 of the 3,346 passengers who embarked on the Sept. 6 cruise continued back to San Juan with the ship, arriving Friday.
Others had been flown home from St. Thomas, primarily on charter flights organized by Carnival.
