We have supplied over a thousand robust, effective tunnel thrusters to the fishing, transport and aquaculture industries for almost 30 years. A PMH thruster has a simple yet robust design, is very flexible and can be fitted to almost all types of hull. Our thrusters can be delivered for electrical or hydraulic solutions.
Thrusters from PMH are designed for use in harsh environments and tough conditions, with excellent performance and reliability in the most cost-effective manner.
We supply two types of thruster technology: ST and STR. The ST design has a curved tunnel whilst the STR design has a straight tunnel.
STR design
The motor is mounted perpendicular to the tunnel with a 90 degree gear, making it ideal for fitting under the main propeller shaft.
ST design
The ST design has no angled gear, but a direct drive line through propellers and motor, meaning minimal complications and moving parts. The construction is service-friendly and easy to adapt to almost all hull types, and is especially suited to catamarans.
Thrusters with complete maneuvering system
We supply pumps, valves, cooling system and electronic control systems for hydraulically-driven thrusters. We supply frequency converters and control systems for electrically-driven thrusters.
Our control systems are prepared for integration with thruster control systems such as MPTC and dynamic positioning systems such as Keep Position.
