Cruise Ship Propulsion

Azipod cruise ship propulsion system is situated outside hull in aft of the ship.

Cruise ship propulsion. Ships have undergone tremendous change over the years. Ships like Norwegian Epic Carnival Dream and. 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.

Currently most ships are driven by a screw propeller which is illustrated in Fig. Modern cruise ships use either gas turbine or diesel electric engines as their power source for propulsion as well as for the ships systems. Without suitable means of propulsion ships will be just floating iron mountains and nothing more.

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. The keys to sailing the seas in such style are the four 290-ton podded electric propulsors two fixed. The most basic forms of propulsion are sails or with a paddle.

Some larger ships rely on two different power sources. Diesel engines diesel-electric engines. The electric propulsion system used on merchant ships is categorized into twotypes depending upon type of prime mover attached to it.

The basic structure and parts of a modern cruise liner is shown in figure. There are numerous types of ship propulsion systems. Starting on a high note.

One for propulsion and one exclusively for electrical power. 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. 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.
