Singapore sets methanol bunkering standard for green shipping

The Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore (EnterpriseSG), through the Singapore Standards Council (SSC), have published Technical Reference (TR) 129 on Methanol Bunkering. This new framework sets clear guidelines for the safe and efficient use of methanol as an alternative marine fuel, reinforcing Singapore’s position as a leading multi-fuel bunkering hub.

TR 129 establishes stringent requirements for custody transfer, operational safety, and accurate measurement of methanol in ship-to-ship bunkering. It includes:

• Custody transfer protocols ensuring quality and quantity control in methanol bunkering.
• Operational and safety measures for bunker tanker deliveries, including crew training frameworks.
• Use of mass flow meters (MFM) for precise fuel quantity management and digital documentation.

Developed by a working group under the Singapore Chemical Industry Council (SCIC), the standard is the result of collaboration between government agencies, industry leaders, and research institutions.

Industry leaders endorse TR 129

David Foo, MPA assistant chief executive (Operations/Operations Technology), described the development of TR 129 as “a collective effort by government agencies, industry partners, and research institutes,” aimed at ensuring the safe adoption of methanol as a marine fuel.

Choy Sauw Kook, director-general (Quality & Excellence) at Enterprise Singapore, emphasised that TR 129 will “equip local operators with the capabilities and confidence to conduct methanol bunkering operations, paving the way for a multi-fuel future in Singapore.”

Driving Singapore’s multi-fuel bunkering ambitions

Following the world’s first ship-to-container methanol bunkering operation in July 2023, MPA conducted simultaneous methanol bunkering and cargo operations at Tuas Port in May 2024. These experiences played a crucial role in shaping TR 129, particularly in fuelling procedures, crew training, and emergency response protocols.

TR 129 aligns with Singapore’s broader strategy to lead the transition to alternative fuels in the maritime sector, reinforcing its status as a global sustainable bunkering hub. Stakeholders can learn more about the standard at an upcoming seminar during Singapore Maritime Week 2025.
