- Cummins’ methanol-ready QSK60 engine gains DNV AIP for IMO II and III compliance.
- Cummins plans methanol retrofit kits for diesel-electric systems post-2028.
- Exploring ethanol and alcohol-based fuels for sustainable marine solutions.
Cummins Inc. has received Approval in Principle (AIP) from the DNV classification society for its methanol-ready QSK60 marine engine, reads an official press release.
The certification, granted in June 2024, covers the IMO II and IMO III versions of the QSK60, with power ranges from 2,000 to 2,700 horsepower. This engine is designed to meet growing demand for more sustainable and lower-carbon solutions in the marine industry.
Transition to lower emissions
Cummins plans to offer retrofit kits for the QSK60 post-2028, addressing the need for fuel infrastructure and market demands. These kits will be particularly beneficial for diesel-electric systems integrated with battery technology, improving energy efficiency and reducing emissions. The company’s broader strategy involves offering retrofit options for existing marine power installations, accelerating the reduction of carbon emissions.
Dawn Wehr, Cummins’ Executive Director, emphasized that retrofitting engines rather than overhauling vessels allows quicker emissions reductions. Furthermore, the company is exploring solutions for other alcohol-based fuels, including ethanol, to ensure flexibility in response to varying fuel availability. This announcement follows Cummins’ 2023 approval to use renewable diesel, such as hydrotreated vegetable oil (HVO), in its high-horsepower engines.
By combining HVO and methanol dual-fuel technology, Cummins aims to help customers transition to lower emissions while striving toward a zero-carbon future for marine propulsion.
