MOL Achieves Japan’s First Ship-to-Ship Methanol Bunkering | Mariner News
Mitsui O.S.K. Lines (MOL) and its partners have successfully completed Japan’s first ship-to-ship methanol bunkering operation. This significant achievement marks a crucial step forward for sustainable shipping and the adoption of cleaner marine fuels in the region. The pioneering fuel transfer, conducted at Keihin Port in the Yokohama district, involved a collaborative effort to supply biomethanol to a dual-fuel vessel, setting a new precedent for maritime decarbonization efforts.
A Landmark Operation in Yokohama
This groundbreaking methanol marine fuel transfer saw the bunkering vessel Eika Maru supply domestically produced biomethanol to the dual-fuel methanol carrier Kohzan Maru VII. Both vessels are chartered by Mitsubishi Gas Chemical Company, with the fuel originating from MGC’s Niigata plant. The initiative involved a consortium of five parties: MOL, the City of Yokohama, Kokuka Sangyo, Idemitsu Kosan, and Mitsubishi Gas Chemical Company, highlighting a united front for Japan’s green transition in shipping.
Driving Sustainable Marine Fuel Adoption
Methanol bunkering is increasingly recognized as a vital solution for reducing greenhouse gas emissions within the maritime industry. As more dual-fuel methanol vessels enter service globally, the demand for this versatile and cleaner energy source is projected to grow. This successful operation underscores methanol’s potential as a future-proof marine fuel, supporting the shipping sector’s ambitious environmental goals and fostering a more sustainable maritime future.
This landmark event not only positions Japan at the forefront of sustainable shipping practices but also provides invaluable insights for expanding alternative fuel infrastructure worldwide. It demonstrates a clear commitment to fostering a cleaner, more efficient global fleet.
