Ocean Network Express (ONE) has been awarded approval in principle (AiP) for an ammonia dual-fuelled container vessel. Just recently, the shipping company also ordered twelve dual-fuel container ships that can sail on methanol.

The newly AiP-awarded 3500 TEU vessel was jointly developed by ONE, Nihon Shipyard (NSY) and classification society DNV, as part of a joint development project established in late 2022 among the three parties.

ONE has been studying the feasibility of ammonia as an alternative fuel for zero emission according to the roadmap for alternative fuels which was developed by ONE in 2022. In conjunction with the roadmap, ONE participated in a GCMD-led ammonia bunkering pilot safety study. ONE wants to achieve net-zero operations by 2050.

Ammonia has potential

‘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,’ explains Koshiro Wake, senior vice president of Corporate Strategy & Sustainability Department at ONE. ‘We are pleased to have made such a progress, and we will continue our study on ammonia.’

Cristina Saenz de Santa Maria, regional manager South East Asia, Pacific & India, Maritime at DNV, adds: ‘Ammonia is one of the promising future marine fuels with great potential to decarbonise 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.’
