◆ Contributing to fuel savings and reduction of GHG emissions for vessels operating at partial load.

Joint Project Ceremony at POSIDONIA 2026 in Athens

Athens/Copenhagen/Tokyo, 3 June 2026 — Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd.（hereinafter “MHI-MME”）and Fonden Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (※1) have agreed to a joint project to promote the『Efficient Operation of Ships – Turbocharger Retrofit Initiatives for Partial Load of Engine（hereinafter “EOS TRIPLE”）』project.

The EOS TRIPLE project focuses on improving the efficiency of main engines on vessels in operation. In normal vessel operations, vessels rarely operate at the engine’s original design point, and in most cases, they run under partial load conditions.

EOS TRIPLE is a technology that improves fuel consumption in the partial load range and aligns engine operation with actual operation conditions and operational profiles by optimizing the turbocharger configuration and other engine parameters.

In this project, we aim to promote the deployment of these energy‑efficiency technologies by simplifying the rules that currently hinder their introduction, reviewing existing certification schemes, and clarifying the allocation of risks and benefits.

MHI-MME will provide technical know-how and engineering expertise to support efficiency improvements in main engines installed on vessels in operation, while also conducting pilot projects to assess the resulting performance improvements.

　　　　

　　　　

（※1）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-drivenrecommendations 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. For more information and overview of partners, please visit www.zerocarbonshipping.com.
