Singapore Unveils New Ammonia Bunkering and Fuel Quality Standards
Cubierto por 3 fuentesPublicado
The Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore, through the Singapore Standards Council (SSC), launched a new Singapore Standard (SS) and two Technical References (TRs) covering ammonia bunkering, bunker fuel sampling, and polymer testing in waste-derived marine fuels. The announcement was made during the Singapore International Bunkering Conference and Exhibition (SIBCON) 2026, with the aim of strengthening fuel safety, consistency, and quality assurance amid the transition toward a multi-fuel future.
Standards for Ammonia Bunkering
Technical Reference TR 148:2026, titled Code of Practice for Ammonia Bunkering, sets out the requirements for carrying out safe and efficient ammonia bunkering operations, including custody transfer, operating procedures, safety, and personnel competency. Under the Singapore-Australia Green and Digital Shipping Corridor, MPA will work together with the Pilbara Ports Authority to validate this reference by exchanging operational experience and information gathered from bunkering trials conducted at their respective ports.
Liquid Fuel Sampling
Singapore Standard SS 730:2026, Code of Practice for Bunker Sampling, establishes requirements for custody transfer sampling of liquid marine fuels at ambient temperature, including Class F fuels derived from petroleum, synthetic, and renewable sources, as well as methanol. The standard provides common sampling procedures and safety requirements for suppliers, bunker vessel operators, buyers, and surveyors.
Polymer Testing in Residual Fuels
Technical Reference TR 155:2026 sets out a common method for detecting polystyrene, polypropylene, and polymethyl methacrylate in waste-derived marine fuels, along with their respective detection limits, aiming to improve consistency in identifying these polymers and strengthen fuel quality assurance.
Official Statements
Ang Wee Keong, Chief Executive of MPA, noted that as shipping transitions toward a wider range of marine fuels, bunkering standards and capabilities must evolve accordingly, and that these new standards will support the industry's transition and strengthen Singapore's capacity to meet the bunkering needs of global shipping. For her part, Choy Sauw Kook, Deputy Chief Executive of Quality & Excellence at Enterprise Singapore, highlighted that standards are a key enabler of maritime decarbonisation, and that together with TR 148, SS 730, and TR 155, they reinforce Singapore's position as a trusted global bunkering hub.
