The Maritime and Port Authority of Singapore (MPA) stated that the implementation of the updated bunker mass flow metering standard would be mandatory from 1 April 2025.

The Maritime and Port Authority of Singapore (MPA) released its port marine circular to inform the maritime industry that it will mandate the use of SS 648: 2024, effective 1 April 2025.

Part one covers pre-approval processes such as meter selection, acceptance tests, etc. Moreover, part two covers post-approval processes such as health, safety and environment requirements. In addition it covers metrological requirements, system integrity requirements and metering procedures.

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.
  • 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.

Furthermore, all in-service bunker cargo officers and bunker surveyors are required to complete this refresher course 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.
