Mecklenburger Metallguss GmbH (MMG) has been manufacturing ship propeller for more than 78 years, focusing on size, quality and efficiency. All propeller are developed, designed and produced at the company’s site in Waren (Müritz), Germany.
All propeller are developed, designed and produced at the company’s site in Waren (Müritz), Germany. According to MMG, its production processes and qualified workforce are aligned with the requirements of classification societies. MMG supplies propellers for both Newbuildings and retrofit projects. To meet evolving industry demands, the company applies a combination of conventional sandcasting and additive manufacturing technologies. These include automated welding systems and large-scale 3D printing, enabling the production of complex geometries and customised designs. A central element of its activities is a propeller Re-Design-program, under which more than 700 vessels have been retrofitted. By adapting propeller designs to updated operational profiles, the programme aims to improve efficiency and reduce fuel consumption in service. The company continues to develop its portfolio, with a focus on optimised propeller designs and the integration of new manufacturing technologies. Current developments also include solutions to reduce noise emissions while maintaining propulsion efficiency.
With a growing focus on pre-swirl, propeller and rudder Interaction, MMG is expanding its expertise towards holistic hydrodynamic solutions for modern propulsion systems. By considering the interaction between hull, wake field, pre-swirl devices, rudder and propeller as one integrated system, we create solutions that combine maximum efficiency with reliable performance. Energy-saving devices such as pre-swirl vanes offer significant potential for improving propulsion efficiency, but their successful application requires careful hydrodynamic integration. MMG combines analysis, simulation and engineering expertise to optimise efficiency while minimising adverse effects such as cavitation and pressure pulses. Investigating cavitation behaviour and pressure pulses before and after installation provides valuable insight into the hydrodynamic effects of pre-swirl systems and supports the development of more efficient and balanced propulsion concepts.
