3rd Propulsion System Cruise Ship

One for propulsion and one exclusively for electrical power.

3rd propulsion system cruise ship. Propulsion of ships normally occurs with the assistance of a propeller. Aside from the normal range of bars and restaurants the ship has a number of facilities that are unique on a cruise ship. Most cruise ships have two pods.

PROPULSION SYSTEM Propellers The three propellers were of 470 meters in diameter and had three blades. Each propeller had a volume of 24 m³ and achieved 270 revolutions per minute at full speed. A lot of space is saved by the Azipod cruise ship propulsion system in the engine room - there is no propeller engine shafting or other arrangements.

A high total cylinder volume a low BMEP a mechanical injection system and. 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 good thing about Azipods is that they do not have engines inside.

Built in 1998 at a cost of approximately 450m the ship was the largest and most expensive cruise ship afloat until delivery of Voyager of the Seas in November 1999. The engines provide a total output of 58000kW. Cruise ships have more variable speed profiles higher tops speeds higher non-propulsion electrical loads and other factors that favor multiple commonly four to six diesel generators providing power for electric motors either in azipods or attached to a shaft.

Currently almost 23 of all large-sized cruise vessels icebreaking ships and high ice-class cargo ships are with Azipod propulsion. The new LNG carriers will be classed to ARC7 the highest ice class rating for merchant vessels. It has three or four or sometimes even more in the case of propellers aimed at working under low noise conditions blades.

Grand Princess is a cruise ship owned by Carnival Corporation and operated by Princess Cruises. ABBs Azipod propulsion system propulsion system where the electric drive motor is located in a submerged pod outside the ship hull can rotate 360 to boost manoeuvrability which is particularly crucial for vessels operating in ice. Not all cruise ships use pods.
