The project will assess pilot turbocharger and engine optimization technology for vessels operating at partial load. This will deliver fuel savings and lower greenhouse emissions across the existing fleet.
Copenhagen, Denmark — Yesterday at Posidonia 2026 in Athens, Fonden Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (the Center) and Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd. (MHI-MME) announced an agreement to advance the development of the Efficient Operation of Ships – Turbocharger Retrofit Initiatives for Partial Load of Engine, EOS TRIPLE project. The agreement builds on the existing strategic partnership and ongoing collaboration between the two organizations within maritime decarbonization. This announcement marks a further step towards delivering tangible, near-term efficiency solutions for the global fleet.
The EOS TRIPLE project focuses on efficiency-enhancing solutions for engines operating under derated or partial load conditions, a common reality in commercial shipping, where vessels rarely operate at the engine’s original design point. The project aims to improve combustion efficiency and fuel performance by optimizing turbocharger configuration and other engine parameters to align engine operation with the actual operation conditions and profiles.
Under this agreement, the Center and MHI-MME will work on the technical definition and maturity assessment of the EOS TRIPLE, evaluate what is needed to bring it to scale, and define how savings are shared and verified among shipowners, operators, and technology providers. The collaboration will also address the regulatory implications of the technology, including the necessary updates to the IMO NOx Technical File. MHI-MME will provide technical know-how and engineering expertise, while the Center will act as ecosystem coordinator, convening stakeholders, supporting the development of the required regulatory framework, and defining the verification and validation methodology.
A focused bet on tangible maritime decarbonization solutions
The EOS TRIPLE project reflects the Center’s ambition to deliver practical and scalable solutions for the industry, supporting the adoption of energy efficiency measures and enabling barrier removal for faster scale up.
This collaboration with MHI is exactly the kind of focused, high-impact work we want to take forward. We are building on our strong foundation and longstanding partnerships to demonstrate solutions and eventually mature standards that will enable scalable decarbonization solutions with clear value for the industry and the planet. The EOS TRIPLE project will help improve the efficiency of engines that are already in operation today and the planned pilot installations will provide valuable learnings to quantify the actual impact of these improvements, as well as an understanding of how to scale such solutions across the industry. MHI’s deep technical expertise makes them an ideal partner to bring this from concept to pilot.”
MHI-MME has been participated several projects of the Center. We are happy to work with the Center for this EOS TRIPLE project, which will deliver fuel savings and lower greenhouse emissions across the existing fleet. It may take time for decarbonization by applying new fuels due to uncertainties, we wish to contribute GHG reduction of the operating vessels through this EOS project, which may be practical and immediate effect, with our marine machinery technology, especially turbocharger design and services.
About the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping
The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) is an independent, not-for-profit research and development center established in 2020 with funding from the A.P. Moller Foundation. Our purpose is to guide and accelerate decarbonization of the global maritime industry.
Working with our partners, governments, authorities, public sector bodies, scientists, and organizations across the global maritime industry we aim to inform, de-risk decision-making, and spark real climate action.
We are technology agnostic and have no vested interest in specific decarbonization solutions. We explore free of commercial considerations and independent of partner strategies. As a result, we deliver independent analyses of how the transition is progressing and clear, data-driven recommendations for accelerating maritime decarbonization. On top we are maturing solutions to the most pressing problems across the maritime value chain, from fuels to onboard solutions, regulations, and financing.
