Drive Systems for Shortsea Vessels
Unlike other types of ship, shortsea vessels are exposed to unforgiving weather conditions.
A failure of a core component would be a risk to cargo and life. The focus here is on robustness without compromise and relentless efficiency. From coasters to Atlantic feeders, we are at your side with help and advice.

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.
Nozzle
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.
Standard 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
Premium Sealings
The Defense Against Water Ingress
Premium sealing systems extend the life of maritime components with options such as distance rings for seal repositioning, carbide coatings to reduce wear, an extra oil-repellent lip to prevent leaks. The “Green Seal” offers an air barrier with an Air Control Unit for environmental compliance, while our rope guards, net cutters, wire winders, and sand barriers protect the seal from external damage. The “Premium Sealing” package promises an extended seal system lifespan, reduced maintenance costs, and a potential operational duration of up to 20 years under certain conditions.
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.
