The Maritime and Port Authority of Singapore (MPA) on Friday (1 November) issued Port Marine Circular No. 12 of 2024 informing the marine industry that the use of SS 648: 2024 for the custody transfer of bunker deliveries to ocean-going ships in the Port of Singapore will be mandatory from 1 April 2025:

This circular serves to inform the maritime industry that the Maritime and Port Authority of Singapore (MPA) will mandate the use of SS 648: 2024 for the custody transfer of bunker deliveries to ocean-going ships in the Port of Singapore from 1 April 2025. Consequently, the use of SS 648: 2019 will cease from 1 April 2025. 

Published by the Singapore Standards Council in October 2024, the SS 648: 2024 serves as the latest version of the SS 648 and is the result of a joint review of the previous version (SS648: 2019) by the MPA, Singapore Shipping Association (SSA), International Bunker Industry Association (IBIA), as well as representatives from bunker suppliers/craft operators, bunker buyers, testing and surveying companies, oil majors, equipment vendors, relevant government agencies and industry experts to meet the changing needs of the bunkering industry. 

The SS 648: 2024 is divided into 2 parts for ease of operational use. Part 1 covers pre-approval processes such as meter selection, acceptance tests, etc.; while Part 2 covers post-approval processes such as health, safety and environment requirements, metrological requirements, system integrity requirements and metering procedures. Other key changes include:  

  • Updating of the acceptance test to include single tanker meter-in meter-out as an additional option for approval of Mass Flow Metering (MFM) system;
  • Considerations after a software update or upgrade to provide better clarity;
  • Biofuels in the coverage of the standard;
  • Use of data logger and edge device with enhanced requirements for data security, data integrity and data transmission requirements;
  • Replacing minimum measured quantity (MMQ) with new table on minimum bunker quantity (MBQ) for better clarity;
  • Updates of the sampling requirements with new information from SS 600:2022 Code of practice for bunkering by bunker tankers using tank gauging;
  • New content on digital documentation to be cross referenced to new Specification for Digital Bunkering Supply Chain Documentation; and
  • Reorganisation of the content of bunker claims procedures and dispute resolution

Training Requirements for Cargo Officers and Bunker Surveyors 

The MPA has worked with SSA and IBIA to develop a refresher course on the new requirements of the SS 648: 2024, which is expected to commence from January 2025. All in-service bunker cargo officers and bunker surveyors are required to complete this refresher course (conducted by SSA and IBIA) by 1 April 2025. Bunker cargo officers and bunker surveyors that have not attained the necessary certification will not be allowed to conduct bunkering operations in the Port of Singapore.

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.
