Our Marine solution Offering

Utilize our engineering expertise for your propulsion system integration.

Our Solution Team is capable of providing interdisciplinary support to ship designers and shipyards across the entire spectrum of propulsion systems from an early stage of the ship-design process. From start to finish – from planning to execution. To ensure perfect integration of the drive into the ship’s structure. From purely mechanical single-motor drives to highly complex hybrid propulsion systems.

Due to our broad technology portfolio and project expertise we have a strong know-how when it comes to intelligently combining the specific technological advantages of electric motors, diesel engines and gas turbines with propellers and water jets, while getting the best value in terms of the operational characteristics and mission capabilities of the ship.

01 Standard mechanical propulsion solution

Ultra-compact, fully customizable and packed with smart options.

Specially designed single-input marine gear boxes ranges from small, compact units for less demanding applications to customized gear boxes that meet the special requirements of all types of ships and/or transmit very high outputs.

  • Customizable through equipment packages for almost any requirement.
  • With technology proven to last in the toughest conditions.
  • Delivering ultimate power density with low weight and a small footprint.

The scope of delivery can also be supplemented by a wide range of additional features for the propulsion system. Optionally, seawater-cooling components, shaft-brake and shaft-turning devices, and external thrust bearings can be selected from RENK’s scope of supply.

02 Combined mechanical propulsion 

Increased performance with optimized fuel consumption.

By offering a tailored combination of diesel engines for lower speeds and additional diesel or gas turbines, RENK ensures that the engines always run in their efficient speed range avoiding low- load operation, thus enabling a combination of maximum performance and maximum efficiency in a single solution.

  • Space saving and precise integration into your engine room.
  • Optimum drive power at all times thanks to combined drive systems.
  • Tailored to your engines and your specific application profile.

We offers the broadest variety of configurations, such as CODAD, CODOG/CODAG, and COGOG/COGAG.

03 Hybrid propulsion

Flexibility, efficiency and low noise in one system - that is what hybrid propulsion is all about. 

By offering tailor-made combinations of mechanical and electric drives, RENK opens up completely new possibilities for naval applications that enhance performance while simultaneously reducing costs.

  • With low noise, low vibration gear units and electric drives for low speed ranges.
  • Flexible arrangement of the drive combinations to your individual requirements.
  • Optimized fuel efficiency but utilizing the main engine.

From supplementing combined mechanical propulsion systems with an electric motor to the sophisticated CODELAG/ CODELOG variant – the perfectly matched combinations of mechanical and electric drives enable not only exceptionally quiet operation at lower speed ranges, yet also offer maximum power without compromise at high power density.

04 SIlent Propulsion 

Electric drive systems: the silent power on all seas.

Electric propulsion offers many advantages for specific applications, in particular quiet operation. That is why we have developed the AED (Advanced Electric Drive), which meets all requirements of the naval sector. It enables research vessels and navy ships  to operate with extremely low-noise signature of the vessel. The AED can withstand severe shock impacts and guarantees propulsion and maneuvrability of the vessel in any scenario.

  • Unsurpassed low noise solution for silent missions.
  • Excellent power-to-weight ratio.
  • Flawlessly integrates into the onboard system.

The AED can be used as a stand-alone solution or incorporated in a hybrid solution design. Get in touch with our engineering experts to evaluate the best fit for your demands.
