What is an Azipod on a cruise ship?

Azipod® propulsion is a gearless steerable propulsion system where the electric drive motor is housed within a pod outside the ship hull.

What is the difference between azimuth and Azipod?

is that azimuth is an arc of the horizon intercepted between the meridian of the place and a vertical circle passing through the center of any object; as, the azimuth of a star; the azimuth or bearing of a line surveying while azipod is (nautical) an azimuth thruster, an engine and ships’ propeller in an underslung pod …

Who invented the Azipod?

Developed in Finland jointly by the shipbuilding company Masa-Yards and ABB, Azipod is a marine propulsion unit consisting of a fixed pitch propeller mounted on a steerable gondola (“pod”) which also contains the electric motor driving the propeller.

Do cargo ships have Azipods?

Azipod is actually the registered trademark for ABB’s brand of azimuth thrusters that was first introduced in 1987. Today, ABB’s Azipod propulsion systems are used on a wide range of vessels such as cruise ships, icebreakers, ice-going cargo vessels and offshore accommodation ships.

Are Azipods AC or DC?

Azipod® is the electrically driven propulsor with an AC motor incorporated in a streamlined azimuthing pod unit directly driving a fixed-pitch propeller.

What is Z drive propulsion?

A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder.

How azimuth angle is calculated?

The azimuth angle is like a compass direction with North = 0° and South = 180°. Other authors use a variety of slightly different definitions (i.e., angles of ± 180° and South = 0°).

How are Azipods powered?

Azipod® is the electrically driven propulsor with an AC motor incorporated in a streamlined azimuthing pod unit directly driving a fixed-pitch propeller. The motor is controlled by a frequency converter, which produces full nominaltorque in either direction over the entire speed range, including standstill.

How does Z Peller work?

Z-Peller consists of a power transmission system that drives a propeller and a rotation system that adjusts the propeller direction 360 degrees. On the outer periphery, the propeller is equipped with a Kort nozzle which serves to increase the propeller thrust.

How does Z-drive work?

A Z-drive replaces the propeller, shaft, stern tube, marine gear, rudder and steering gear all with a single unit. Z-Drive azimuthing thrusters provide maximum thrust in any direction, independent of vessel speed, offering superior pinpoint maneuverability under all conditions. Rudders are completely eliminated.

How do I get my azimuth back?

Back azimuths are calculated as follows: If the original azimuth is less than 180 degrees you ADD 180 degrees to the original azimuth, thus an azimuth of 45 degrees (<180) will have a back azimuth of 225 degrees. If the original azimuth is greater than 180 degrees you SUBTRACT 180 degrees from the original azimuth.

What is meant by azimuth angle?

The azimuth angle is the compass direction from which the sunlight is coming. The azimuth angle is like a compass direction with North = 0° and South = 180°. Other authors use a variety of slightly different definitions (i.e., angles of ± 180° and South = 0°).

What do you need to know about Azipod co?

Azipod® CO – bringing the benefits of podded propulsion to a whole new range of vessel types Azipod ® CO is an azimuthing propulsion system providing high overall propulsion efficiency and fuel savings for modern, environmentally-friendly ships.

What kind of propulsion system is the Azipod?

Azipod is an electric podded azimuth thruster produced by ABB Group. Developed in Finland jointly by the shipbuilding company Masa-Yards and ABB, Azipod is a marine propulsion unit consisting of a fixed pitch propeller mounted on a steerable gondola (“pod”) which also contains the electric motor driving the propeller.

What was the fuel efficiency of the Azipod?

In order to get the most out of it, shiphandling training on simulators and manned models is required. The podded design typically achieved a 9% better fuel efficiency than the conventional propulsion system when it was first installed in the 1990s.

When was the Azipod first installed on a ship?

The first Azipod unit, installed on the Finnish fairway support vessel Seili in 1990, is now displayed at the Forum Marinum maritime museum in Turku, Finland.
