NYK Line has completed the world's first ship-to-ship ammonia bunkering operation at the Ariake Shipyard. The transfer to an ammonia-fueled medium gas carrier is part of a broader strategy to utilize carbon-free fuels in international shipping.
Why it matters
This test demonstrates a viable pathway for decarbonizing marine logistics by utilizing ammonia, which produces no carbon dioxide during combustion. As regulators and customers push for greener supply chains, this operational milestone provides a template for future marine fuel transitions.
The pilot involved the inaugural ship-to-ship ammonia bunkering operation using the Shoei Maru, moving toward the delivery of an ammonia-fueled vessel. The total scale of the bunkering procedure follows established safety protocols developed specifically for this vessel class.
The players
NYK Line
A major global shipping and logistics company that operates a diverse fleet of vessels.
Shoei Maru
The vessel utilized to perform the ammonia transfer during the bunkering operation.
The details
The procedure involved transferring ammonia directly between the Shoei Maru and a medium gas carrier at the Ariake Shipyard. By establishing rigorous operating procedures and safety processes beforehand, the company successfully demonstrated the mechanics of ship-to-ship refueling. This shift is designed to prepare the industry for the integration of carbon-neutral vessels into commercial fleets.
Timeline
September 17, 2026: The first ship-to-ship ammonia bunkering operation was completed.
November 2026: The ammonia-fueled medium gas carrier is scheduled for delivery.
Market Landscape
This development follows a trend of testing zero-carbon marine fuels to meet tightening international emissions requirements. It extends the industry's reliance on ammonia-fueled medium gas carriers as a primary testbed for decarbonizing the global shipping fleet.
Operators in the logistics and shipping sectors should monitor the safety standards emerging from this trial to inform future fleet procurement strategies. This process establishes a functional precedent for handling ammonia, which may influence future port infrastructure and fuel cost structures.
The takeaway
The successful bunkering of ammonia highlights a maturing operational approach to zero-emission marine logistics. Operators should track the performance of the upcoming vessel delivery in November 2026 as an industry signal for fuel scalability.
What happens next
The industry will monitor the delivery of the ammonia-fueled medium gas carrier scheduled for November 2026.
