ONE earns AiP for ammonia dual-fuel vessel

Ocean Network Express (ONE) has been awarded Approval in Principle (AiP) by DNV for an ammonia dual-fuel container ship design.

Developed by ONE, Nikon Shipyard Co and DNV, the 3,500 teu vessel design is the result of a joint development programme launched in late 2022.

“Ammonia is definitely one of the primary focuses of our research as ammonia fuel has a great potential of generating lower GHG emissions than conventional marine fuels. We are pleased to have made such a progress, and we will continue our study on ammonia.” said Koshiro Wake, senior vice president of Corporate Strategy & Sustainability Department at ONE.

ONE’s research into ammonia as a marine fuel was laid out in its 2022 roadmap for alternative fuels and has included participation in a GCMD-led ammonia bunkering pilot safety study in Singapore.

The container line has not limited itself to one fuel however. Earlier this month ONE placed an order for its first 12 methanol dual-fuel container ships which will be built at Jiangnan Shipyard and Yangzijiang Shipbuilding with delivery dates from 2027.

"Ammonia is one of the promising future marine fuels with great potential to decarbonize shipping. We are confident that DNV's rules for ammonia will help our customers to safely adopt this new fuel type once the infrastructure is in place. We are grateful to our JDP partners for entrusting us with this pioneering project that will help the entire maritime industry to adopt ammonia as a marine fuel”, said Cristina Saenz de Santa Maria, regional manager South East Asia, Pacific & India, Maritime at DNV.
