What is the capability of a Azimuth thruster with Nozzle?
Sep 28, 2018

The Azimuth thruster with Nozzle is a Z-type propulsion device that combines the functions of a ducted propeller and a steering gear. The underwater part can be steered by 360-degree free rotation to form an all-round thrust. The device combines the high efficiency of the ducted propeller with the maneuverability of the full-rotation rudder propeller. It is mainly used in various engineering vessels with high maneuverability requirements or dynamic positioning requirements, such as port tugboats, submarine cabling vessels, floating cranes. Ships, offshore platforms and platform supply vessels.


The Azimuth thruster with Nozzle enables the propeller or duct thruster to rotate 360° about the vertical axis in the horizontal plane through the bevel gear system transmission mechanism for propelling and maneuvering the propeller of the vessel. Because of its zigzag arrangement, it can simultaneously propel and manipulate the ship.


Compared with the traditional propeller, the Azimuth thruster with Nozzle can change the direction of the thrust arbitrarily, so that the ship can be turned in place, and it can move forward and backward freely. This kind of propulsion device can be assembled in the workshop. It does not need underwater operation. It is very convenient to install and maintain. It is often used for ships with high maneuverability, such as ferries.


The main output power of Azimuth thruster with Nozzle is rotated by the primary bevel gear and transmitted to the propeller through the secondary bevel gear to form a zigzag transmission system. There is also a hydraulic pump to drive the worm gear to drive the entire thruster device to make 360° horizontal rotation, with the ability to rotate, translate and reverse.
