Engines manufacturer MAN Energy Solutions said it has signed a memorandum of understanding (MOU) with Stena Teknik – Stena’s inhouse R&D division – and Proman – the world’s second largest methanol producer – regarding their mutual cooperation on a project to retrofit MAN 48/60 engines to make them capable of dual-fuel, diesel and methanol operation.

The move comes as ship owners and operators explore alternative fuels such as methanol to help reduce their environmental impacts. Stena and Proman announced their partnership to develop a methanol retrofit and fuel-supply solution last year.

Stefan Eefting, Head of PrimeServ Germany, and Bernd Siebert, Head of Retrofit & Upgrades, signed the MoU on behalf of MAN Energy Solutions, while Ron Gerlach, Technical Director signed on behalf of Stena. Peter Schild, Director of Marine Fuels, signed for Proman.

Under the terms of the deal, the project will start with an initial feasibility study, defining the scope and limits of the project, the division of work and respective responsibilities. The primary aim is to investigate methanol combustion according to the Otto combustion principle with MeOH port fuel injection due to the inherent advantages for legacy installations. Developments on MeOH direct injection technology for newbuilds and the potential for later retrofits may also be considered.

Upon successful completion of the feasibility study, the second phase would involve the retrofit of the engine(s), commissioning and field testing. The third and final phase would then involve the completion of field testing, and engine handover for commercial operation.

Eefting said, “MAN Energy Solutions is happy to work with industry partners on decarbonizing the marine segment, a sentiment that Stena and Proman happily share. Methanol has great potential as a future-fuel and is clean, efficient and safe to work with. It offers significant greenhouse-gas reductions, and is even net-zero when produced from renewable energy sources. I’m certain that many interested parties will be watching this retrofit’s progress.”
