The new Singapore Standard, SS 648 – Code of Practice for Bunker Mass Flow Metering (MFM) represents a refinement from the Technical Reference for Bunker Mass Flow Metering (TR 48), says the Managing Director of MFM consultancy Metcore International Pte Ltd.
 
Darrick Pang was giving a presentation at The Bunker Fuel & Ballast Water Compliance Conference & Workshop (BuBWCE) on Wednesday (13 November) when he noted its improvements.
 
“The earlier TR 48 was designed around the custody transfer of fuel oil as a bunker fuel; SS 648 now include areas to handle distillates and multi meter setups,” he told delegates at the Conference Connection organized event.
 
“Another area of enhancement is the inclusion of requirements to cover foreign objects or devices that can affect measurement [of an MFM], thereby further strengthening the integrity of custody transfer.
 
“There are also well-defined rules for operational sealing to ensure there are no other outlets for oil to bypass after the MFM system.
 
“The role of surveyors in MFM bunkering have also been given added emphasis in SS 648.”
 
In his speech, Pang stated MFMs have undergone several challenges since its implementation for bunkering at Singapore since 1 January 2017.
 
“There were a couple of incidents in which attempts were made to tamper the MFM system which goes to show that the MFM is not simply a plug and play system.

“MFM tampering with an external device is actually traceable due to the device’s data logging capabilities.

TR 48 provided us with a solid foundation in MFM system implementation. Over the years as we build up our system’s knowledge and experience, we recognise there were some areas we can improve on and this was indispensable during the early stages of SS 648 discussion.
   
The SS 648 was launch earlier in November to support the changing needs of the bunker industry as it transits to a low Sulphur fuel oil regime in January 2020 to meet International Maritime Organization (IMO) regulations. 

Manifold Times earlier reported Metcore assisting bunker supplier Victory Petroleum Trading Pte Ltd in meeting requirements for final acceptance tests under challenging conditions due to the size of the latter’s marine gas oil bunker tankers.

The Singapore company has also helped an Athens-based supplier and bunker tanker meet TR 48:2015 standards by sending its engineers to Greece to oversee the entire operation.

Metcore is among firms recognised by the China Petroleum Circulation Association Marine Fuel Industry Committee (CPCA-MFC) supporting the growing bunkering industry at Zhoushan.

Hong Kong’s Marine Department (MD) on Wednesday (3 June) launched the Quality Bunker Operator Scheme to encourage bunker operators to install and use mass flow meter systems (MFM systems) on their bunker vessels.

MD said the scheme aims to enhance Hong Kong’s bunkering service quality and the competitiveness of Hong Kong ports, thereby further consolidating Hong Kong’s position as an international maritime centre and a major bunkering port.

Under the Scheme, bunker operators of traditional maritime fuel and biodiesel that install and use MFM systems on their bunker vessels, with the MFM systems inspected and certified by an accredited body in accordance with the International Organization for Standardization’s ISO 22192 Standard or equivalent requirements, can apply to the MD for inclusion in the scheme’s “List of Quality Bunker Vessels”, provided they meet the relevant technical and operational requirements. 

Details of the bunker vessels successfully included in the List will be published on a dedicated page on the MD’s website for reference by shipping companies and relevant stakeholders.

Participation in the Scheme is voluntary. In addition to receiving recognition from the MD, participating bunker operators will benefit from enhanced corporate image and competitiveness through the adoption of MFM systems, thereby boosting customers’ confidence and helping to create new business opportunities.

 A spokesman for the MD, said: “As an international maritime centre supported by our country, Hong Kong has a strategic location adjacent to major international fairways. Coupled with years of development in marine fuel bunkering, Hong Kong possesses rich experience and talent in the field. For many years, Hong Kong has consistently ranked as the seventh-largest bunkering port globally, the second-largest in our country, and the largest in the Greater Bay Area, providing reliable and competitive fuel bunkering services to ocean-going vessels from around the world. 

“As the international shipping industry has an increasing demand for accuracy and transparency in bunkering services, service quality and measurement precision in bunkering operations have become important indicators of a bunkering port’s competitiveness. The Scheme will enhance bunkering accuracy and transparency, further enhancing the quality of Hong Kong’s bunkering services.

The spokesman added that comprehensive port services are one of Hong Kong’s key advantages as an international maritime centre.

“We will also mandate the use of MFM systems on all methanol bunker vessels this year to ensure that Hong Kong continues to provide high-quality bunkering services in the era of green maritime fuels.” 

Note: The application form for the Scheme can be found on the MD’s website. Interested bunker operators can download the application form from the website or contact the MD’s Green Maritime Fuel Team via email ([email protected]) for details.

Zhoushan port records 8 million mt annual bunker volume for 2025

Zhoushan Hi-Tech Zone Administrative Committee on Wednesday (7 January) said Zhoushan recorded a bonded bunkering volume of 8.03 million metric tonnes (mt) in 2025, marking a year-on-year increase of 10.6%.

The committee said this is the first time the port has hit the 8 million mt mark for the first time, potentially ranking among the top three bunkering ports globally. 

Manifold Times previously reported Zhoushan delivering 7.26 million mt of marine fuel in 2024.

The committee highlighted the efforts to improve service, cost, and efficiency, while implementing 41 targeted measures in 2025. 

Efforts were made in key areas such as accelerating green transformation, optimising digital supervision, facilitating anchorage bunkering, and consolidating cost advantages, driving comprehensive improvement in the quality and efficiency of industrial development. 

In line with the global trend of green transformation of marine fuel, the city has introduced management measures for green bunkering operations, a joint supervision mechanism for bunkering vessels, and an action plan for green transformation of bunkering, thus improving the regulatory and service system. 

Zhoushan port records 8 million mt annual bunker volume for 2025

The city achieved nearly 120,000 mt of biofuel bunkering. Zhoushan also put into operation an LNG bonded warehouse, commenced construction of the first methanol bunkering vessel, and established the first liquid ammonia bunkering company, accelerating the development of alternative bunker fuels such as LNG, methanol, and ammonia.

The city has continuously explored reforms and innovations in a bunker measurement system, releasing the first provincial standard for mass flow meters in China. 

It has conducted compliance inspections, statutory verifications, and pilot certifications for the installation and use of mass flow meters on barges, and implemented an online e-BDN system, successfully completing trials and entering routine operation. 

This has significantly simplified the processes of metering, handover, and verification, making the city the first in the country to achieve fully digital handover of the bonded fuel bunkering process. 

In July 2025, Zhoushan became the first port in China and third in the world to implement electronic bunker delivery notes (e-BDN) after issuing its first. 

A series of convenient anchorage measures were implemented. Provincial and municipal customs, maritime, and border inspection departments issued a package of facilitation support measures. 

They assessed and optimised nighttime supply conditions, added priority anchorages for bunkering, expanded the number of night time supply barges, and innovatively implemented a “one-window” service for refuelling vessels throughout the customs area, separate supervision and verification for large and small vessels, and simultaneous bunkering and cargo operations (SIMOPS). 

These measures further simplified customs clearance procedures at Zhoushan Port and effectively improved anchorage turnover efficiency and carrying capacity. 

With that, the bunker volume at Zhoushan anchorage reached 2.85 million mt in 2025, a year-on-year increase of 19.1%, becoming the core driving force for market growth. Among them, the bunker volume at Xiushan East anchorage reached 1.48 million mt, a year-on-year increase of 33.45%.

As for infrastructure, the city has accelerated storage and transportation projects for commissioning and expansion, adding 2.53 million cubic metres (m3) of oil and gas storage capacity.

The committee added that specialised policies, such as the “Implementation Opinions on Supporting the High-Quality Development of Zhoushan’s Bonded Marine Fuel Bunkering Industry,” was also introduced to drive cost reduction and efficiency improvement for enterprises.
