Cruise Ship Propulsion

Wind capture propulsion and paddle steamer propulsion are classical ones.

Cruise ship propulsion. 121The propeller wings are set with an. The basic structure and parts of a modern cruise liner is shown in figure. The electric propulsion system used on merchant ships is categorized into twotypes depending upon type of prime mover attached to it.

Slowing the ship to 12 knots at 6000 horsepower could sustain propulsion for up to 200-hou s and provide a theoretical 2000 nautical miles of possible operating range. 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. Azipod units can rotate 360 degrees increasing maneuverability and.

Fast forward 137 years and Norwegian cruise line Hurtigruten has launched the worlds first hybrid-powered cruise ship named Roald Amundsen after the explorer. Built in 2004 for Cunard Line at a cost of 800 million the most expensive cruise ship ever built and christened by Britains Queen Elizabeth II the QM2 includes all the usual and superlative features lavish interiors food and entertainment galore and a pampering crew. Not all cruise ships use pods.

For large ships like cruise ships the most common are. Motions of ships require heavy power generation and an effective propulsion system. There are numerous types of ship propulsion systems.

Some larger ships rely on two different power sources. The Azipod propulsion unit azimuths through 360 and incorporates an electric AC motor located inside the propeller pod. The larger the cruise ship the greater the demand for electrical power.

See at the first photo at right the Cunard Queen Mary 2 cruise ship propulsion system scheme. Azipod cruise ship propulsion system can be placed below the ships height and provide more efficiency than conventional systems. Azipod turns in all directions 360 degrees by a rudder providing thrust in any directions not possible for conventional systems.
