Enterprise Singapore (ESG), a statutory board under the Ministry of Trade and Industry of the Government of Singapore administering the Singapore Standardisation programme, on Tuesday (8 October) launched two new bunkering standards while revising a third benchmark at the 23rd Singapore International Bunkering Conference and Exhibition (SIBCON 2024).

The ESG development was introduced by Captain Rahul Choudhuri, Chair of Technical Committee for Bunkering (Ambient Liquid Fuel), also President – Strategic Partnerships at VPS, who shared the following during his keynote speech to delegates.
TR on Methanol bunkering
“In view of the push to decarbonise bunkering, standards in alternative fuels such as LNG, biofuels, and methanol were developed (with ammonia under development) to ensure quality and quantity assurance as well as safe handling and operations,” said Captain Choudhuri.
“The new TR on Methanol Bunkering has been established by Singapore to support decarbonisation efforts, coupling with the soon-to-be published ISO 6583 ‘Methanol as a fuel for marine applications standard’ covering the quality aspects of methanol for marine applications.”
SS on Specification for digital bunkering supply chain documentation
“The year, to boost operational efficiency in bunkering, we are also happy to share with you the newly developed Specification for digital bunkering supply chain documentation. This standard helps to ensure interoperability between systems and facilitate smooth business transactions between companies using trusted and verifiable digital documentation,” he stated.
SS 648 Code of practice for bunker mass flow metering
Captain Choudhuri noted TR 48, the predecessor of SS 648, was first developed in 2015 at Singapore for the delivery of marine fuel oil. SS 648 was first introduced in 2019; its revision started in 2022 and published in 2024.
Research concluded the standard’s adoption has resulted in potential cost savings in bunkering operations accounting for an estimated 66% to 76% of total savings at between USD 62 million to 154 million annually.
Beyond cost savings, use of TR 48 improved efficiency, productivity and transparency of bunkering transactions.
The SS 648 Code of practice for bunker mass flow metering was revised in 2024 to incorporate digital bunkering workflow and processes.
This standard provides guidance on Metering system selection, installation and acceptance test requirements, metering procedures during bunker delivery, dispute handling, and bunker quality specifications including sampling process of bunkering.
