It’s been a rough year for Costa cruise ships. After at least 25 people were killed last month when a Costa ship hit a reef, the cruise line has suffered its second accident this year.

A fire broke out Monday on the Costa Allegra, a ship in the same fleet as the sunken Costa Concordia, the Associated Press reported. No injuries were reported, and the ship is now immobilized off the coast of the Seychelles in the Indian Ocean.

In a statement, the company said a general emergency alarm was “promptly sounded” and that there were no injuries or casualties. More than 1,000 passengers were evacuated. It did not say what caused the fire.

In January, the Costa Concordia cruise ship hit a reef off Italy’s tiny Tuscan island, causing it to list dramatically to one side. The crash killed 25, with seven others still missing. Costa Concordia’s captain is under investigation. Since 1998, there have been at least 10 other major accidents on Carnival cruise ships.

Costa Cruises was acquired by Carnival Corporation, the world’s largest cruise operator, in 2000. It accounts for approximately 16 percent of Carnival’s revenue.

Update: BlogPost reader wrote in to say that an earlier post that we erred in writing the Costa Allegra was a sister ship to the Concordia. “A sister ship is a ship that is the same class and almost identical design. These 2 ships are obviously not even remotely identical. The Allegra is 28,000 tons and built in 1969 and the Concordia is 114,000 tons and first sailed in 2006 (new).”
