MS Mariner of the Seas is one of five Voyager-class cruise ships from Royal Caribbean International; it is one of the largest in its fleet and among the largest passenger ships in the world. It was constructed at Aker Finnyards in Turku, Finland in 18 months. Currently the ship sails 7-night round trips from Los Angeles to the Mexican Riviera and is currently captained by Per Kristoffersen. She has replaced the route previously sailed by the Vision of the Seas.


Main propulsion

The ship has a diesel-electric powertrain using three Azipod azimuth thrusters. Each propeller is driven by a double wound 3-phase synchronous motor with 4-bladed bronze propellers of azipod type. The motors are mounted outside the hull directly on the propeller shaft inside the pod. The three propellers are arranged so that the center propeller is a pushing on–azimuthing Fixipod-type and the two wing ones are of pulling-azimuthing–type steering propellers.

  • Motors: three 14,000 kW (18,800 hp) at 145 rpm each
    • Total: 42,000 kW (56,000 hp)
  • Stabilizers: 4 Brown Brothers Stabilizer Fins
  • Bow Thrusters: 4 KAMEWA 3000 kW each
  • Maximum speed: 24 knots (44 km/h)
  • Fuel consumption at full speed: 10,637 kg/h (2,871 gal/h)


Six Wärtsilä Diesel 12V46 generators producing 12,600 kilowatts each for a total of 75,000 kilowatts or 103,000 bhp. All gensets are monitored by the Wärtsilä CBM (Condition Based Maintenance) group by using Wärtsilä automatic data sending concept.

Fresh water production

The ship has three ways in which to produce fresh water—Two Alfa Laval Desalt Flash and Energy Recovery Evaporators and one Pall Rochem seawater desalination unit (reverse osmosis) "Rosmarin" 80404-50/300-A-SW

  • Steam evaporator: 230,000 gallons[vague] (900 metric tons) per day
  • Seawater desalination unit (reverse osmosis): 80,000 gal (300 t) per day
    • Total freshwater production: 540,000 gal (2,100 t) per day
  • Water consumption: 58 U.S. gallons (220 liters) per person per day
  • Ice cube production: 65,000 lb (29,000 kg) per day
