Diesel Fixed Pitch Azimuth Thruster


Application

A diesel fixed pitch azimuth thruster is a type of propulsion system that is commonly used in marine vessels. It consists of a diesel engine that drives a propeller or impeller, which is mounted on a movable pod or housing that can rotate 360 degrees around a vertical axis. The fixed pitch design means that the pitch of the propeller blades is fixed and cannot be adjusted during operation. The diesel fixed pitch azimuth thruster is typically used in larger vessels, such as offshore supply vessels, tugboats, and passenger ferries, where high levels of maneuverability and precise control are essential. It is particularly useful for dynamic positioning and station-keeping operations, where the vessel needs to remain in a specific location, regardless of the wind, waves, or current.

Features

1. Driving type:diesel engine.

2. Good maneuverability and low noise.

3. The product can be customized.
