THE Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore (EnterpriseSG) have published a new Technical Reference (TR) 129 on Methanol Bunkering through the Singapore Standards Council (SSC).

TR 129 sets out requirements covering safe handling, transfer, and measurement of methanol in bunkering operations, writes London's Port Technology International.

The requirements include custody transfer comprising quantity and quality measurements for ship-to-ship methanol bunkering operations; operational and safety requirements for the delivery of methanol from a bunker tanker to receiving vessels, including a framework for crew training and competencies.

Guidance on the use of mass flow meters (MFM) to ensure accurate quantity management and digital documentation for bunkering.

TR 129 was developed by the Working Group (WG) on Methanol Bunkering, supported by the Standards Development Organisation at Singapore Chemical Industry Council (SDO@SCIC).

The WG comprises government agencies, research institutes, and industry stakeholders such as bunker suppliers, bunker craft operators, engine manufacturers, testing and certification bodies, shipowners and operators, among others.

David Foo, MPA assistant chief executive (Operations/Operations Technology), said: "The development of the Technical Reference 129 on the safe and efficient use of methanol for bunkering in Singapore is the result of the collective efforts by government agencies, industry partners, and research institutes.

"It provides clear guidelines to support the safe adoption of methanol as a marine fuel and gives the industry greater confidence in their transition to use of sustainable fuels."

Choy Sauw Kook, director-general (Quality & Excellence), Enterprise Singapore, said: "TR 129 will help to equip our local operators with not only the capabilities, but confidence to carry out methanol bunkering operations, and pave the way towards a multi-fuel future in Singapore."
