Cummins secures DNV AiP for methanol-ready QSK engines

These kits are designed for diesel-electric systems, and can be integrated with battery technology for hybrid propulsion to reduce emissions.

DNV’s approval builds on Cummins’ drive to enable the use of renewable diesel, such as hydrotreated vegetable oil (HVO), across its high-horsepower engine range. By using renewable diesel in dual-fuel solutions, vessel operators can make significant progress towards reducing carbon emissions.

“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,” said Cummins vice president for power systems in industrial markets, Gbile Adewunmi. “This announcement is a strong example of the investment and technology advancements Cummins is making to further our destination-zero strategy.”

Cummins manufactures diesel-fuelled QSK60 four-stroke engines in Daventry, UK, with low-temperature aftercooling from an engine-mounted titanium plate heat exchanger and a dry exhaust manifold with water shielding for reduced fuel consumption and improved performance.

Its air system includes Cummins turbochargers optimised for marine applications with two pumps and two loops. A QSK60 engine has a displacement of 60.2 litres, a bore of 159 mm and stroke of 190 mm.
