Caterpillar has been awarded approval in principle (AiP) from DNV for its fuel-blending conversion solution for MaK engines, aligning with a fuel-blending conversion pilot project conducted at a testing facility that allows M 20 to M 43 and legacy engines to lower GHG emissions up to 20%.
The dual-fuel conversion enables M 32 and M 43 engines to operate on up to 95% methanol or ethanol by volume which lowers GHG emissions up to 80% based on original carbon intensity of the fuel; tailpipe emissions are the same as with fossil fuels.
Enacted in 2025, 2050 FuelEU Maritime Regulations advance the industry’s GHG emissions reduction ambitions – and operators’ interest in pragmatic pathways to modernise trusted existing assets. Given operators’ substantial investments in current fleets as well as the high cost of newbuild vessels, converting existing ships to operate on lower carbon-intensity fuels enables established vessels to remain in service for longer while aligning with industry requirements. This strategic approach provides fuel flexibility port to port, ensuring the engines’ inherent ability to run on alcohol-based fuels.
Andy Law, Caterpillar Marine VP, said: “Our extensive dual fuel expertise, advanced diagnostics, digital solutions and global service capabilities empower operators to meet evolving industry requirements in practical ways that help curb Opex and preserve capital. We’re collaborating with operators worldwide to help them thrive as the industry shifts.”
Sven Rosenow, Caterpillar global services director, MaK, added: “Keeping pace with FuelEU Maritime requirements is essential to not only ensure vessels remain on the water but also to avoid significant financial penalties. Our fuel conversion solutions give operators options and enable them to modernise their fleets in ways that are ideal for their unique operations.”
Will Watson, global product director, Caterpillar Marine, said: “We’re helping operators position their fleets for 2050 and beyond. We’re creating customised roadmaps for each operator that optimises for the nuances, application and true operational profile of each vessel to maximise each operator’s outcome.”
