From the initial planning to the final turn
Thanks to a constant focus on reliability, top performance, and environmental friendliness, shipping companies, shipyards, and captains have been placing their trust in us for more than three decades.
Going for the extra step
6 steps for an efficient drivetrain
Step 1
Consulting, Analysis & Project Planning
The end justifies the means – In the center of every propulsion concept must be the purpose of the vessel. Everything else follows. Together, we determine the tasks to be fulfilled, provide advisory support at every step, and find ship-specific solutions. Task, operating profile, propulsion, and vessel form a unity that we strive to optimize to the fullest.
Step 2
Hydrodynamic optimization
Efficiency and smooth running are too important to be just an option. If you have chosen the parameters well in the first step, every drive system and each propeller undergoes an optimization process based on this. In this case, our hybrid concept provides the most reliable results from: design data and drawings of over 72,000 built propellers, polynomial regressions, fast calculating lifting surface methods, and our own 1,400 core high-performance computer.
Step 3
Construction and Calculation
From the first line to the last decimal point – Calculation and construction require a strict schedule. Many different influencing parameters have to be weighed against each other and adjusted. It is important to maintain focus here. In the background, continuous calculations are made to check every value for plausibility. Modern project and drawing management systems are, of course, part of our tools, as are complex simulation programs for torsional vibration, strength (FEM), ice class, and alignment. This ensures that we deliver a robust system that you can always rely on. Even after decades, we can derive adjustment designs from this data.Step 4
Production
From Europe to the global stage – quality is our top priority. Together with our European partners, we produce systems that move the world. We place value on producing in regions where broad knowledge and long tradition prevail. Our propellers come from Spain and Portugal, while the shipbuilding and mechanical engineering parts are produced in the Netherlands and Germany. Our strictly selected partners have been among the best in the world for decades. Because only the best is good enough.
Step 5
Service
It must rotate and should never stop. When the ship is in the water, the champagne bottle has shattered on the hull, and the crew moves to the next project, the time comes for our service team. The greater the likelihood of damage, the closer we are. Therefore, every 400km along the Rhine, you will encounter a friendly and competent face. When it burns, the light still shines in the workshop for a long time, even if it is not the spotlight.
Step 6
Recycling
Back into the cycle after the last propeller revolution. Depending on the load and the selected material thickness of the propeller, its lifespan can be extended, but the point of farewell comes, as painful as it is. The material structure can no longer withstand the load and begins to crack. A new propeller is indispensable. Here we have teamed up with our partners and developed a unique concept. We melt down the propeller and return it to the material cycle. In this way, we produce sustainably efficient drive systems that were already efficient during their usage period.
Promarin Multipulsion®
No compromise, silent and efficient. Not only does the Multipulsion® eliminate harmful harmonics, it also smears the vortices that normal propellers develop at their blades tips, which can cause destructive cavitation and extreme noise. These improvements do not come at the cost of a higher fuel consumption because the Multipulsion® is still a propeller in the classical sense – just more intelligently made.
Your service partner with competence
Our propeller service range from inspection, straightening and balancing to the complete repair of a defective propeller. Using the most modern methods, we analyse the situation and find the best solution.
As an official Reintjes service partner, we take care of all necessary work on the gearbox, whether it is a replacement filter or a major overhaul. Thanks to short supply chains, a large warehouse and direct contact, we can always react quickly.
