The ship's power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing each and three similar 12-cylinder Wärtsilä 12V46D engines producing each. The fuel consumption of the main engines at full power is of fuel oil per engine per hour for the 16-cylinder engines and per engine per hour for the 12-cylinder engines. The total output of these prime movers, some , is converted to electricity, used in hotel power for operation of the lights, elevators, electronics, galleys, water treatment plant, and all of the other systems used on the operation of the vessel, as well as propulsion. Propulsion is provided by three Azipods, ABB's brand of electric azimuth thrusters. These pods, suspended under the stern, contain electric motors driving propellers. Because they are rotatable, no rudders are needed to steer the ship. Docking is assisted by four transverse bow thrusters.
