System Solutions
Drive Systems for Fast Ships
Fast ships require high power, high peripheral speeds, and special propellers.
In this context, cavitation can no longer be prevented; it must be controlled. With our high-technology approach, we ensure smooth operation and peak performance.

Propeller
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.
ISO484 Measurement & 3D Scanning
Unique Quality Inspection With 3D Scan
The Promarin propellers are scanned in our quality department to ensure the highest accuracy. The combination of ISO484 measurement and 3D scanning enables the production of a propeller whose geometric shape is optimized for maximum efficiency, while minimizing the risk of noise or damage due to cavitation. CFD simulations of the scanned propeller to predict the propeller’s performance before the trial run are available upon request.
ActiveStrut® Technology
For Optimized Flow Efficiency
Sealings
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
Gearbox
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.
