What are propulsion pods?
POD is one type of azimuth propulsion consisting of an integrated electric motor / propeller unit mounted on the same shaft, installed in a gondola under the stern of the ship. Typical of the evolved POD propulsion is that the propeller pulls the ship as opposed to the conventional, less efficient pushing action.
What is retractable thruster?
The Retractable Azimuth Thruster operates in full azimuth mode when deployed as part of an auxiliary propulsion system to increase the vessel’s station-keeping capabilities. A tunnel can be incorporated in the design of the outer well so that the thruster can be used as bow thruster as well.
What is the function of thruster?
A thruster is a propulsive device used by spacecraft and watercraft for station keeping, attitude control, in the reaction control system, or long-duration, low-thrust acceleration.
How does azimuth thruster work?
In an azimuth thruster the propeller rotates 360° around the vertical axis so the unit provides propulsion, steering and positioning thrust for superior manoeuvrability. Designs have been developed for propulsion and dynamic positioning in response to market requirements.
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 much is a bow thruster?

What thruster means?
one that thrusts
Definition of thruster : one that thrusts especially : an engine (such as a jet engine) that develops thrust by expelling a jet of fluid or a stream of particles.
What is the purpose of azimuth thruster?
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system.
Who invented azimuth thruster?
The azimuth thruster using the Z-drive transmission was invented in 1950 by Joseph Becker, the founder of Schottel in Germany, and marketed as rudder propeller . Later on, relevant literature was studied and many modifications were suggested in the design of the thrusters.
What is an azimuth thruster?

Where are electric azimuthing propulsion pods made?
Electric Azimuthing Propulsion Pods – Welcome to PT. Marine Propulsion Solutions Marine Propulsion Solutions is a leading manufacturer of Electric Podded Thruster and Propulsion Systems, with units operational for over 15 years with our sales & marketing offices located in Singapore and production facilities in Batam.
What is the difference between azimuthing and podded propellers?
The essential difference between the azimuthing and podded propellers lies in where the engine or motor driving the propeller is sited. If the motor is sited in the ship’s hull then the system would be termed an azimuthing propulsor and most commonly the mechanical drive would be of a Z or L type to the propeller shaft.
What is the function of the stem of a thruster?
The stem of the thruster accommodates shafts that are connected to a motor located inside the ship. The Azimuth thrusters are divided into two types based on the position of the motor.
