Cummins Inc., a global leader in power solutions, has received Approval in Principle (AiP) from DNV for its methanol-ready QSK60 marine engine, covering both IMO II and IMO III compliance levels. This certification, granted in June 2024, validates Cummins’ ability to retrofit its high-horsepower engines with methanol dual-fuel technology, ensuring compliance with stringent safety and performance standards in the maritime sector.
With power outputs ranging from 2,000 to 2,700 hp (1,491 – 2,013 kW), the QSK60 retrofit solution aims to provide vessel operators with a cost-effective pathway to decarbonization. By allowing existing diesel engines to be converted to methanol dual-fuel systems, Cummins is facilitating a gradual transition to cleaner fuels without requiring full engine replacements.
Retrofit Kits to Be Available Post-2028
Following extensive field testing, Cummins plans to introduce its methanol retrofit kits after 2028. This timeline aligns with the expected expansion of methanol bunkering infrastructure and growing industry adoption of alternative fuels. The retrofit solution is particularly suited for diesel-electric propulsion systems, offering enhanced integration with battery storage to optimize fuel efficiency and reduce carbon emissions.
Cummins’ initiative builds on its broader strategy to support the energy transition in the maritime industry. The company’s announcement in November 2023 outlined its commitment to facilitating engine conversions, ensuring shipowners can seamlessly transition to greener technologies while maintaining operational efficiency.
Industry Commitment to Sustainable Fuels
Dawn Wehr, Executive Director – Strategy, Product Planning & Digital at Cummins, emphasized the advantages of retrofitting over full engine replacements:
“Using a retrofittable solution dismisses the need for a major vessel overhaul and creates an immediate positive impact on carbon-emissions reduction. With our continual work on developing solutions for other alcohol fuels, including ethanol, we are committed to providing solutions that work for different operations and fuel infrastructure availabilities to ensure ease of adoption.”
This approval also builds on Cummins’ August 2023 decision to allow the use of renewable diesel, such as hydrotreated vegetable oil (HVO), in all its high-horsepower engines. By integrating HVO into its dual-fuel solutions, Cummins enables shipowners to make incremental but significant reductions in emissions, advancing their decarbonization strategies without compromising performance.
Supporting the Transition to Zero-Emission Shipping
Gbile Adewunmi, Vice President of Industrial Markets – Power Systems Business at Cummins, underscored the company’s broader vision:
“Cummins is committed to delivering innovative power solutions to the marine industry. Through partnerships with our customers, we can drive solutions that meet application requirements, sustainability targets, as well as bridge the longer-term goal of zero emissions. This announcement is a strong example of the investment and technology advancements Cummins is making to further our Destination Zero strategy.”
The approval of Cummins’ methanol-ready QSK60 engine represents a milestone in the maritime industry’s shift toward cleaner fuels. As regulatory pressures increase and global shipping companies strive to meet decarbonization targets, methanol is emerging as a viable alternative fuel. Cummins’ retrofit solution ensures that vessel operators have a flexible, practical pathway toward greener operations.
