Mitsubishi Shipbuilding Co., Ltd., a division of Mitsubishi Heavy Industries (MHI) Group, has secured orders from Toyofuji Shipping Co., Ltd. (based in Aichi Prefecture) and Fukuju Shipping Co., Ltd. (based in Shizuoka Prefecture) for Japan's pioneering methanol-powered roll-on/roll-off (RORO) cargo vessels. Construction of the two ships will take place at MHI's Shimonoseki Shipyard & Machinery Works Enoura Plant in Yamaguchi Prefecture, with expected completion and delivery by the end of fiscal 2027.

The vessels will have an approximate overall length of 169.9 meters and a breadth of 30.2 meters, with a gross tonnage of 15,750 and a capacity to carry approximately 2,300 passenger vehicles.

A windscreen at the bow and a vertical stem are utilized to minimize propulsion resistance, while fuel efficiency is enhanced through MHI's proprietary energy-saving system technology, integrating high-efficiency propellers and advanced rudders designed for reduced resistance. The main engine features a high-performance dual-fuel capability using both methanol and heavy fuel oil, achieving over 10% reduction in CO2 emissions compared to similarly sized ships powered solely by fuel oil, thereby contributing to environmental sustainability. Future adoption of green methanol could potentially lead to additional CO2 emissions reductions across the fuel's lifecycle.

Methanol-powered RORO ships are already operational on global ocean routes, but this marks the first construction of coastal vessels specifically designed for service in Japan.

Furthermore, the substantial increase in vehicle loading capacity and transport capacity per voyage compared to conventional vessels will offer more flexibility in ship allocation schedules. This will ensure more downtime and rest periods for the crew, contributing to improvements in working conditions.

Mitsubishi Shipbuilding remains committed to addressing increasing demand driven by the shift to marine transport amidst efforts to reduce CO2 emissions in land transportation, tackle labor shortages, and reform working styles. The company will collaborate with its business partners to develop ferries and RORO vessels that offer outstanding fuel efficiency and environmental performance. These efforts aim to ensure reliable navigation solutions that meet diverse societal needs.

The new roll-on/roll-off (RO/RO) ship boasts impressive specifications tailored for efficient maritime transport. With an overall length (LOA) of approximately 169.9 meters and a beam of about 30.2 meters, it accommodates a gross tonnage of around 15,750. The ship's main capacity highlight is its ability to carry approximately 2,300 passenger vehicles, catering to substantial cargo needs. Powered by a service speed of up to 21.0 knots, the vessel is designed to ensure swift and reliable transport operations, meeting the demands of modern maritime logistics effectively.

Mitsubishi Heavy Industries (MHI) Group stands as a global leader in diverse industrial sectors encompassing energy, smart infrastructure, industrial machinery, aerospace, and defense. Leveraging advanced technology and extensive expertise, MHI Group innovates integrated solutions that promote a carbon-neutral future, enhance quality of life, and foster global safety standards.
