MAN PrimeServ, the after-sales brand of MAN Energy Solutions, has announced a new retrofit package set to be available from 2025. This package will allow customers to convert their existing conventional MAN four-stroke engines to dual-fuel methanol operation. Initially, customers will have the option to convert their MAN 48/60 engines to the latest MAN 51/60DF engine type with methanol capability.
The conversion package has been in development for some time and has undergone extensive testing at MAN Energy Solutions’ plant in Augsburg, Germany since the summer of 2024. MAN PrimeServ plans to convert the first four-stroke engines for a pilot customer in autumn 2025 before making the package available to the general market.
Stefan Eefting, Head of MAN PrimeServ Germany, emphasized the importance of synthetic fuels for achieving climate-neutral shipping. He highlighted the economic attractiveness of the methanol retrofit package, offering customers a cost-effective way to convert older engines to a future-proof type. Alexander Knafl, Head of Engineering R&D Four-Stroke at MAN Energy Solutions, expressed confidence in the engine efficiency and optimization for both diesel and methanol operation.
