The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, in collaboration with TSUNEISHI SHIPBUILDING Co., Ltd., has obtained an Approval in Principle (AiP) for retrofitting a conventionally fueled Kamsarmax bulk carrier to operate on dual-fuel methanol, according to the company's release.
This project evaluated the techno-economic feasibility of converting vessels from fuel oil to methanol, aiming to establish a model for broader adoption within the medium-sized bulk carrier sector.
The retrofit design, based on Tsuneishi’s Kamsarmax standard, was developed with input from MAN Energy Solutions, which provided expertise on main engine and fuel system design.
ClassNK offered regulatory guidance, facilitated safety risk assessments, and granted the AiP. Cargill contributed operational and technical insights, while the Danish Maritime Administration participated as an observer during risk assessments.
The project produced multiple design solutions, including modular fuel handling and methanol storage options aimed at optimizing safety and reducing conversion costs and lead times.
General design principles for methanol retrofits were also developed to assist ship designers, shipyards, and operators. These findings will be published in a comprehensive case study and a set of guidelines later this year.
Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping is an independent, non-profit research and development center established in 2020 with funding from the A.P. Moller Foundation. The center aims to accelerate the decarbonization of the global maritime industry through collaboration, applied research, and regulatory reform.
