A complete range of bow and stern thrusters from OMS and Hundested Propeller. Our power ranges from 15kw to 2000+kw (20 - 2700 + hp) in both electric and hydraulic variants. Available as fixed tunnel units, vertical retracting and swing retracting units.
Tunnel
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.
Tunnel thrusters are supplied complete with a mounting saddle, all gaskets/ fasteners and a suitable interface for any hydraulic or electric motor. The motor is driven via a flexible coupling to reduce noise and vibration.
Vertical
Vertical retracting thrusters benefit from the same in-hub technology as our tunnel thrusters, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. This compact design uses a lead screw lift assembly with a reduction gearbox to ensure that the thruster hub, when retracted, is held firmly in place.
The vertical thruster is also very useful where vessels have a deep V profile so the thruster is fitted higher providing a longer deployment stroke to clear the hull. They can also be fitted further forward or aft than a conventional tunnel thruster increasing the turning moment of the hull and therefore requiring less power input.
For added security, all vertical retracting thrusters can be manually raised or lowered in case of power failure. To ensure there is no environmental risk, the main drive motor, hydraulic hoses and electric cables are inside the vessel so are not open to seawater.
Vertical Retracting and Rotating
Our vertical 360° rotating thrusters benefit from the same in-hub technology as the fixed tunnel thruster, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. This type of thruster has a very small footprint so is ideally suited to installation in aft or fore lockers where space is at a premium.
The vertical rotating thruster is also very useful where vessels have a deep V profile so the thruster is fitted higher providing a longer deployment stroke to clear the hull. They can also be fitted further forward or aft than a conventional tunnel thruster increasing the turning moment of the hull and therefore requiring less power input.
This type of thruster uses a vertical lead screw and guide rods to raise and lower the unit via a motor. As with the swing thruster, all motors and hoses are concealed within the vessel so are not in direct contact with seawater. We have worked with a number of boat builders to optimise the range offered. The rotation mechanism allows you to position the pod and provide 360 degrees of thrust.
The rotating thruster has also been installed and used as emergency propulsion.
Swing
The swing thruster benefits from the same in-hub technology as the fixed tunnel thruster, whilst allowing the thruster to fully retract leaving a fair hull with minimal drag. These types of thrusters are usually used in applications where they are positioned within the accommodation area of a vessel. The low profile and compact design allow them to be easily fitted below floor bearers or in low level lockers, under beds or among other locations.
This compact design uses a lead screw lift assembly with a reduction gearbox to ensure that the thruster hub, when retracted is held firmly in place and cannot move. In addition, OMS swing thrusters feature a locking pin which adds additional security when locking the leg in the raised position. The main drive motor and hydraulic hoses or cables are fully enclosed within the upper leg assembly so are not open to seawater. We have worked with a number of boat builders to optimise the range offered.
