Japan Sees First Ship-to-Ship Ammonia Bunkering
Japan has completed its first ship-to-ship (STS) ammonia bunker transfer operation, with fuel transferred to a new ammonia-fuelled vessel.
The operation took place on September 17 at Japan Marine United’s Ariake Shipyard, NYK Line said in a press release issued on Friday.
Ammonia carrier Shoei Maru transferred the fuel to an ammonia-fuelled medium gas carrier being prepared for delivery later this year.
NYK Line, Japan Marine United, Nihon Shipyard, Mitsubishi Gas Chemical and Kokuka Sangyo were involved in the operation.
In 2023, the companies had signed contracts to build the world's first ammonia-fuelled medium gas carrier equipped with Japanese-made engines.
The vessel is due for delivery in November and will use ammonia for its sea trials.
The companies worked together on procedures for the transfer, with a focus on the safe handling of ammonia.
Unlike conventional marine fuels, ammonia is toxic and requires additional precautions during bunkering.
Maritime transportation company Exmar already operates two ammonia-fuelled vessels, with two more set to join its fleet. Its first ammonia-fuelled vessel completed its first commercial voyage using ammonia as marine fuel earlier this year.
