Cruise Ship Propulsion

See at the first photo at right the Cunard Queen Mary 2 cruise ship propulsion system scheme.

Cruise ship propulsion. Ships like Norwegian Epic Carnival Dream and. This week VPO Global visited the small Norwegian city of Tromso to get a glimpse into how Hurtigrutens latest ship is setting new standards for fuel-efficient and cleaner propulsion. The most basic forms of propulsion are sails or with a paddle.

Ships have undergone tremendous change over the years. 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. In case the ships have large breadth two or more azipod systems independent from one another can be used to provide subtle maneuvering.

Some larger ships rely on two different power sources. The larger the cruise ship the greater the demand for electrical power. Even though the Azipod was initially developed for icebreaking vessels cruise ships have become the largest group of ships by type to be fitted with Azipod propulsion system since the 1990s and the success of the electric podded propulsion units has paved the way for competitors such as the Rolls-Royce Mermaid.

Azipod turns in all directions 360 degrees by a rudder providing thrust in any directions not possible for conventional systems. 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. Wind capture propulsion and paddle steamer propulsion are classical ones.

One for propulsion and one exclusively for electrical power.

Marine propulsion is the way ships generate power to move through the water.

The electric propulsion system used on merchant ships is categorized into twotypes depending upon type of prime mover attached to it. Azimuthing propulsion devices used for propulsion of large cruise ships are at present known under patented name AZIPODs where the electric propulsion motor is contained in a rotatable housing or nacelle submerged under water. The Azipod propulsion system was developed by Kvaerner Masa-Yards and ABB Marine.
