Marine Stern Thruster

Application
Tunnel thrusters are just like the azimuth thrusters, which are used behind a ship for propulsion, except that these thrusters are placed inside a tunnel, an opening from one side of the hull to the other, in the aft (stern) of the ship. It is used to provide thrust to the vessel to move sideways. Also, the whole setup is immovable meaning, the impeller in the tunnel can create only athwartship force. Ships equipped with tunnel thrusters can be identified by the symbol of a big cross in a red circle on both sides of the hull above the waterline over each of the thrusters.

Features
1.Type:Controllable-pitch and Fixed-pitch propeller type.
2.Installation type:Vertical and horizontal installation.
3.High efficiency and endurance.
4.Driven force:Electrical and Hydraulic motor.
5.Suitable for various kinds of vessels such as Transportation vessel, tugboat, ocean engineering vessel, ro/ro ship, cargo liner.
6.Underwater structure are convenient for maintenance and repairing.
7.We can design and manufacture the product according to client's drawing or sample.
