Cummins gains DNV approval for methanol-ready marine engine

Cummins Inc. (CMI) has received DNV Approval in Principle (AiP) for its

methanol-ready QSK60 IMO II and IMO III engines, with outputs ranging from 2000

– 2700 hp (1491 – 2013 kW).

Following extensive field testing, Cummins plans to launch the retrofit

kits post-2028 to align with market demand and infrastructure readiness.

These kits will be especially useful for diesel-electric systems that may

be linked to a battery, increasing efficiency and sustainability.

Cummins reported in November 2023 that this program, which focused on

converting existing engine installations, will ensure a smooth transition from

present to future ship building using cleaner technology.

Dawn Wehr, Cummins Executive Director – Strategy, Product Planning &

Digital, added: “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.”

In November 2024, DNV expanded emissions regulations to reduce emissions

from oceangoing vessels while in Californian ports.
