In a landmark achievement for sustainable shipping, the hydrogen-fueled oil tanker KIKOU MARU has received the highest “S” rating under the Zero-Emission Accelerating Ship Finance Program, jointly operated by the Development Bank of Japan (DBJ) and ClassNK. This marks the first application of the program to a coastal vessel, setting a new benchmark for environmentally responsible maritime operations.
Pioneering Hydrogen Propulsion Technology
Owned by Uyeno Transtech Ltd. and built at Fukuoka Shipbuilding Co., Ltd.’s Nagasaki Yard, the KIKOU MARU is designed as a “hydrogen fuel ready” electric propulsion oil tanker. The vessel will participate in one of the world’s first hydrogen-fueled demonstration voyages in 2026 under The Nippon Foundation’s “Zero Emission Ships” project. This initiative reflects Japan’s broader efforts to decarbonize its shipping sector amid tightening global emissions regulations.
ClassNK Evaluation and Sustainable Innovation
ClassNK awarded the “S” rating following a rigorous evaluation using its comprehensive scoring model that measures decarbonization performance, environmental innovation, and operational safety.
Key features of the KIKOU MARU include:
-
Specialized hull structures to safely accommodate hydrogen fuel tanks.
-
Lithium-ion battery integration to improve fuel efficiency and reduce emissions.
-
Advanced electric propulsion systems enabling quiet, efficient, and clean operations.
These design innovations not only ensure compliance with safety and sustainability standards but also position the vessel as a technological model for future zero-emission ships.
Advancing Maritime Decarbonization
The KIKOU MARU’s recognition under the program underscores Uyeno Transtech’s leadership in driving maritime sustainability. The “S” rating reflects the company’s strategic investment in clean energy technologies and reinforces Japan’s role as a frontrunner in next-generation ship design.
As DBJ and ClassNK continue to expand the Zero-Emission Accelerating Ship Finance Program, the initiative is expected to catalyze greater adoption of low- and zero-emission vessels across the shipping and shipbuilding sectors paving the way for a greener, more resilient maritime future.
