Cummins Inc. has made significant strides in the marine engine sector by securing Approval in Principle (AIP) from DNV for its methanol-ready QSK60 marine engine. This certification, which applies to both IMO II and IMO III versions, marks a pivotal step towards enhancing sustainability in marine operations.
Cummins Methanol ready
Cummins’ QSK60 engine is designed for methanol dual-fuel operation, with power ratings from 2,000 to 2,700 hp.
The engine features advanced in-cylinder technology to meet stringent emissions standards.
Retrofit kits for existing engines will be available post-2028, facilitating a smoother transition to cleaner technologies.
The initiative aligns with Cummins’ broader commitment to reducing carbon emissions in the marine industry.
Overview of the QSK60 Engine
The QSK60 engine is engineered to operate efficiently with methanol, a cleaner alternative to traditional marine fuels. It incorporates a robust engine block suitable for continuous duty, a modular common rail fuel system, and low-temperature aftercooling. These features ensure compliance with the International Maritime Organization’s (IMO) Tier 2 and Tier 3 emissions regulations, which are critical for reducing the environmental impact of marine operations.
Future-Proofing Marine Operations
Cummins plans to introduce retrofit kits for the QSK60 engine after 2028. These kits will allow existing vessels to upgrade to methanol dual-fuel systems without the need for extensive overhauls. This approach not only minimizes downtime but also significantly reduces carbon emissions, providing an immediate positive impact on the environment.
Dawn Wehr, Cummins’ Executive Director of Strategy, Product Planning & Digital, emphasized the importance of this retrofittable solution, stating, “Using a retrofittable solution dismisses the need for a major vessel overhaul and creates an immediate positive impact on carbon-emissions reduction.”
Commitment to Sustainability
Cummins’ recent approval for the QSK60 engine builds on its earlier announcement regarding the use of renewable diesel, such as hydrotreated vegetable oil (HVO), across its high-horsepower engine range. This dual approach of integrating methanol and renewable diesel technologies positions Cummins as a leader in the transition towards lower-carbon solutions in the marine sector.
The company is also exploring the use of other alcohol-based fuels, including ethanol, to ensure adaptability across various operational needs and fuel availability. This commitment to innovation reflects Cummins’ dedication to meeting the evolving demands of the marine industry while striving for a long-term goal of zero emissions.
DNV AIP
The DNV AIP for Cummins’ methanol-ready QSK60 engine represents a significant advancement in marine technology, paving the way for a more sustainable future in maritime operations. By focusing on retrofitting existing engines and integrating cleaner fuel options, Cummins is not only addressing current emissions regulations but also setting the stage for a greener marine industry.
