Fixed Tunnel Thrusters

OYS Fixed Tunnel Thrusters are compact and easy to fit units that can be supplied complete with steel, aluminium or composite tunnels, pre drilled ready for installation.

The Thruster hub units are protected by twin shaft seals on each propeller shaft, and a single shaft seal on the vertical input shaft. The Tunnel Thruster uses high torque spiral bevel gears and twin contra-rotating propellers to develop a high thrust to tunnel diameter ratio.

OYS Thruster systems are supplied complete with a mounting saddle, all gaskets/fasteners and a suitable motor table interface that can take either hydraulic or electric motors. Motors are driven via a flexible coupling to reduce noise and vibration. All thrusters come complete with suitably sized primary motor.
