The Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore have launched a code of practice for ammonia bunkering, TR 148:2026, setting requirements for custody transfer, operating procedures, safety and personnel competency. It was announced at SIBCON 2026 alongside new standards for fuel sampling and polymer testing.
Australian Validation
Under the Singapore-Australia Green and Digital Shipping Corridor, MPA and Australia’s Pilbara Ports Authority will validate TR 148 by sharing operational experience from bunkering trials at their ports. The Singapore Chamber of Maritime Arbitration has also opened consultation on a Singapore Ammonia Bunkering Form, a model contract for suppliers and buyers.
