The Carnival Corp. has signed a multibillion dollar contract to build four next-generation LNG-powered cruise ships. The deal is part of the larger previously announced memo of understanding with Meyer Werft and Fincantieri. Two of the vessels will be manufactured for Aida Cruises at Meyer Werft’s Papenburg yard in Germany, while two will be built in Turku, Finland. Additional information about the Turku pair, including which brand(s) is (are) getting them, will be made available at a later date.

Each ship will have 5,000 lower berths and total capacity of 6,600 passengers, giving them the largest guest capacity in the world, out sizing even royal Caribbean’s 6,400 passenger oasis-class ships. Tonnage will exceed 180,000gt.
