Royal Caribbean?s fifth in series Post-Panamax
precedes larger Ultra Voyager class cruise ship

Mariner of the Seas, the fifth cruise ship in the Voyager-class for Royal Caribbean Cruises, was delivered in October of last year. Even before then, such was the operational success of the first four ships in the series that Royal Caribbean had placed an order for an even larger cruise ship ? the Ultra Voyager.
With a gross tonnage of approximately 140,000, a passenger capacity of 3,800 and a crew capacity of 1,200 persons, the current Voyager-class cruise ships are today among the biggest cruise ships afloat. The total length of the Mariner of the Seas is 311 metres, the breadth is 39 metres at waterline level and the height from the keel to the top of the funnel is more than 72 metres. This Post-Panamax size has allowed for unique design features and interior solutions, such as a four-deck high horizontal promenade, a 1,320-seat theatre, a three-deck restaurant and an ice-skating rink.
The Voyager-class cruise ship was devised by Kvaerner Masa-yards in close cooperation with Royal Caribbean, and the Mariner of the Seas? layout is the work of the yard together with several renown architects from the USA, Norway, Sweden and the UK. Built in an extremely short time for a vessel of its size, production of the Mariner of the Seas began in summer 2001. She was docked out in February 2003 with sea trials taking place seven months later.
The vessel has a very high level of plant redundancy. Plant that has an impact on the safety of the vessel has a redundancy built into it so that at least 50% of nominal capacities remain available after any single failure. The ship has Det Norske Veritas RP ? Redundant Propulsion classification ? said to be the highest level of redundancy classification.
By way of propulsion systems, there are three azimuthing electric 14MW Azipod units ? the two side units are fully azimuthing, while the centerline unit is a fixed Azipod. The vessel has been designed to manage 40 knots in side winds and to help cope with this there are also four three megawatt tunnel thrusters in the bow.
The new and bigger Ultra Voyager, which will also be built at the Kvaerner Masa shipyards and is scheduled to arrive in May 2006, will be more than 15% larger than the Mariner of the Seas. The US$807 million giant will measure 339 by 39 meters, stand some 18 stories high and carry a crew of 1,400. A second Ultra Voyager class cruise ship is also scheduled for 2007. n
