Cruise ship propulsion. 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. Currently most ships are driven by a screw propeller which is illustrated in Fig. Side thrusters use is eliminated as pods can be used to provide side thrust.

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. Ships have undergone tremendous change over the years. 121The propeller wings are set with an.

Elation is fitted with two 14MW Azipod propulsion units. 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. The first Azipod propulsion order for a cruise ship came in 1995 for Carnival.

One for propulsion and one exclusively for electrical power. Fast forward 137 years and Norwegian cruise line Hurtigruten has launched the worlds first hybrid-powered cruise ship named Roald Amundsen after the explorer. It is fully developed in cruise ships where it has opened up usable space for passenger cabins to bring greater revenue to owners.

Azipod cruise ship propulsion system is situated outside hull in aft of the ship. In case the ships have large breadth two or more azipod systems independent from one another can be used to provide subtle maneuvering. The larger the cruise ship the greater the demand for electrical power.

The basic structure and parts of a modern cruise liner is shown in figure. Modern cruise ships use either gas turbine or diesel electric engines as their power source for propulsion as well as for the ships systems. 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.
