Cruise Ship Propulsion

Ships have undergone tremendous change over the years.

Cruise ship propulsion. The basic structure and parts of a modern cruise liner is shown in figure. SHAFT IN LINE PROPULSION Justifying the name the shaft from prime mover is used to turn the propeller by either with the help of high speed motor or by reduction gear or directly by a slow speed motor. Ships like Norwegian Epic Carnival Dream and.

Azipod turns in all directions 360 degrees by a rudder providing thrust in any directions not possible for conventional systems. Diesel engines diesel-electric engines. Side thrusters use is eliminated as pods can be used to provide side thrust.

See at the first photo at right the Cunard Queen Mary 2 cruise ship propulsion system scheme. Azipod cruise ship propulsion system is situated outside hull in aft of the ship. Electric propulsion in passenger cruise ships and navy warships offers minimum noise and vibration and maximum usable space for paying passengers or for combat weapons.

It is fully developed in cruise ships where it has opened up usable space for passenger cabins to bring greater revenue to owners. The Azipod propulsion system was developed by Kvaerner Masa-Yards and ABB Marine. Azipod units can rotate 360 degrees increasing maneuverability and.

Elation is fitted with two 14MW Azipod propulsion units. Currently most ships are driven by a screw propeller which is illustrated in Fig. Pod-propulsion is an industry standard today in passenger cruise ships and has been applied also for product tankers two refits icebreakers and offshore vessels.

The Azipod propulsion unit azimuths through 360 and incorporates an electric AC motor located inside the propeller pod. The most basic forms of propulsion are sails or with a paddle. Several ships have a combination of azimuthing pods and pods that do not turn sometimes called fixipods that are used to provide forward and backwards propulsion.
