Drive Systems for Tugboats

If there were one word to define a tugboat, it would be 'power'.

Our high-technology complete system includes, alongside the high-performance nozzle, robust transmissions, and sealing solutions specifically designed for use in the harbour. Seaworthy Ships: Unlike other types of ships, seaworthy ships are exposed to relentless weather conditions. A failure of a core component here would put cargo and lives at risk. Focus is on uncompromising robustness and ruthless efficiency.

The Optimum in Sharp Focus

When a concept becomes a drawing and glowing bronze turns into a shining masterpiece, our experts have once again created one of the world’s finest products that have captivated the maritime industry since the dawn of the modern era. Thanks to the combination of machine learning and simulation, you have the opportunity to access tomorrow’s propeller technology today.


Designed for Maximum Thrust

While customization to client requirements is standard practice in propeller design, standard nozzles are still prevalent in the industry today. Promarin aims for high efficiency under actual working conditions and has developed a custom nozzle solution based on CFD-based regressions.

ActiveStrut® Technology

For Optimized Flow Efficiency

In the wake of every structure, a distinctive flow state known as wake is formed. To optimize the overall efficiency of a ship, it is crucial that the supporting struts— the braces holding the propeller—are designed to enhance rather than disrupt the flow dynamics. Promarin’s innovative ActiveStrut® system adjusts these struts to align favorably with the working propeller’s flow, helping to reduce negative impacts such as vibrations and noise, thereby maximizing efficiency.


Reliably Standard

The area between water and ship should be very well sealed. Especially where the shaft line penetrates the ship’s hull, high rotational movements require special attention. Modern sealing technology relies on lip seals. Here, the gap between the rotating shaft and the static seal is very small, resulting in very low leakage rates. At the same time, the contact surface of the seal is minimized, leading to lower mechanical losses


Foundation of Performance

A robust gearbox is far more than just a key component of a reliable propulsion system – it is the centerpiece that defines power transmission, thus significantly influencing the performance and efficiency of the entire vessel. High-quality and precisely manufactured gears are of crucial importance, as they represent outstanding component quality, which is indispensable in efficient, durable, and high-performance gearboxes.

We are happy to help!

Every single component plays a crucial role in the reliable conversion of the ship's energy. This kind of propulsion necessitates a robust base, which is provided by our comprehensive technological systems. Our portfolio is completed by propellers of unparalleled accuracy.​
