Marine Electric Azimuth Thruster


Application

Marine electric azimuth thruster is for main propulsion and steering of displacement vessels. Azimuth thrusters are used when enhanced maneuverability is required in applications such as dynamic positioning, ship escort and ship docking services. And the azimuth thruster is driven by electric motor. A marine electric azimuth thruster is a type of propulsion system used in marine vessels. It consists of an electric motor that powers a propeller or impeller, which is mounted on a movable pod or housing that can rotate 360 degrees around a vertical axis. This allows the thrust to be directed in any direction, providing excellent maneuverability and control for the vessel. The azimuth thruster is typically used in situations where precise maneuverability is required, such as in offshore drilling rigs, dynamic positioning vessels, and other types of specialized ships. They can be used in both open seas and shallow waters, and are particularly useful for dynamic positioning, station-keeping, and towing operations.

Features

1. Available in CP or FP propeller,Z-drive or L-drive.

2. Steering gear for 360 degrees rotation.

3. Installation types:Transom installation,well installation and deck installation.

Advantages

1. Easy to operate and install.

2. Compact construction and high efficiency with lowest possible fuel consumption.

3. We can customize the product according to customers' requirements.
