From 1 January 2026, bunker vessels operating in Rotterdam and Antwerp-Bruges must be equipped with a certified Mass Flow Meter (MFM) system for the delivery of fuel oil, diesel, and biofuels. The move is designed to tighten control over fuel transfers, a process that has long faced scrutiny for quantity discrepancies.
Aiming for Transparency in the Bunker Market
The decision by the two major European ports follows research by CE Delft and others, which confirmed recurring issues in fuel delivery accuracy. Authorities have responded by mandating MFMs to ensure every tonne of fuel transferred is measured precisely. Similar measures are already in place in Singapore, setting a benchmark for global standards.
The requirement is aligned with the international ISO 22192 standard for MFM systems, though certain parts cannot be directly adopted under European rules. Still, the ports are pressing forward with a unified framework to match practices seen in other leading bunker hubs.
Certification and Compliance
Operators must not only install MFMs but also ensure they are certified before the 2026 deadline. Certification details must be submitted to the harbour master or port captain, forming part of the bunker permit conditions. Enforcement will include random inspections and investigations based on market signals. Non-compliance could lead to fines or, in severe cases, the revocation of bunker licences.
The Role of the Bunker Surveyor
While technology is taking a central role, human expertise remains critical. The bunker surveyor’s responsibilities will adapt but not disappear. Surveyors will still oversee the process, though their focus will shift towards understanding and monitoring the data produced by MFM systems. To support this transition, the International Bunker Industry Association (IBIA) is offering training programs in both Rotterdam and Antwerp.
The port authorities stress the importance of using qualified surveyors familiar with the new systems. This reflects a broader effort to keep trust in the market intact while modernising bunkering procedures.
Industry Preparedness
The regulation represents a significant operational shift for bunker suppliers. Installing and certifying MFMs requires investment and planning, while also bringing bunker practices in Europe closer to global norms. Rotterdam and Antwerp-Bruges, both critical energy and logistics gateways, are positioning themselves at the forefront of efforts to standardize transparency in marine fuel supply.
