- ClassNK will provide the world’s first accreditation for “Machinery Room Safety for Ammonia” (MRS) to NYK’s ammonia-fuelled medium gas carrier (AFMGC).
- This AFMGC is reportedly being built by a partnership led by NYK and Nihon Shipyard Co., Ltd. (NSY).
The world’s first accreditation for ‘Machinery Room Safety for Ammonia’ (MRS) will be granted by ClassNK for the ammonia-fuelled medium gas carrier (AFMGC) which is currently being developed by a consortium that includes Nippon Yusen Kabushiki Kaisha (NYK) and Nihon Shipyard Co., Ltd. (NSY), reads a NYK press release.
Accreditation for ‘Machinery Room Safety for Ammonia’
The MRS is a Class notation demonstrating a ship is equipped with excellent ammonia safety measures for the machinery room space. It also confirms the vessel meets the highest safety measures under the guidelines for ammonia-fuelled ships.
The intention is that the AFMGC will be delivered by the end of November 2026. The vessel development is under the Green Innovation Fund Project which has been initiated by Japan’s New Energy and Industrial Technology Development Organization (NEDO).
The minimum design requirements for using ammonia safely on board are regulated in the ammonia-fueled ship guidelines issued by ClassNK. To receive an MRS notation, it is necessary to satisfy the requirement to minimize personal exposure to leaking ammonia in the machinery room.
