Cruise Ship Propulsion

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.

Cruise ship propulsion. Motions of ships require heavy power generation and an effective propulsion system. 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. The electric propulsion system used on merchant ships is categorized into twotypes depending upon type of prime mover attached to it.

It is fully developed in cruise ships where it has opened up usable space for passenger cabins to bring greater revenue to owners. Azipod units can rotate 360 degrees increasing maneuverability and. Space saving is obvious big.

Opposite to the azimuthing propellers mentioned above that usually were of rather small power not exceeding several. In case the ships have large breadth two or more azipod systems independent from one another can be used to provide subtle maneuvering. Without suitable means of propulsion ships will be just floating iron mountains and nothing more.

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. Some larger ships rely on two different power sources. 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.

For large ships like cruise ships the most common are. Marine propulsion is the way ships generate power to move through the water. The first Azipod propulsion order for a cruise ship came in 1995 for Carnival.

Displace-ment is thus equal to the total weight all told of the relevant loaded ship nor-. Starting on a high note. Ships like Norwegian Epic Carnival Dream and.
