The authorities governing the majority of Europe's largest bunkering hub are planning to make the use of mass flow meters (MFMS) compulsory from the start of 2026, nine years after Singapore first started to impose a similar mandate, according to Ship & Bunker.
Last week, officials from the Port of Rotterdam and the Antwerp-Bruges Port Authority held a meeting with local bunker-industry stakeholders to set out their vision for the change.
The authorities plan to make the use of MFMs mandatory for all bunker barges over 300 GT in size from the start of January 2026, three sources familiar with the situation told Ship & Bunker last week.
This will apply to both conventional bunker and biofuel blend deliveries, but not yet other alternative fuels.
The plan has yet to be finalised. Feedback on the initial plan is being sought until October 10, and the authorities intend officially to announce the strategy at the ARACON industry event in Rotterdam on October 19.

The Antwerp-Bruges authority's jurisdiction also covers Zeebrugge. Amsterdam -- the third major port in the ARA hub- does not at present plan to join in with this strategy, but a source told Ship & Bunker other ports in the region beyond Rotterdam and Antwerp-Bruges were increasingly showing interest in it.
Some discussion in the market has focused on whether the implementation date could be pushed back by a year to January 2027, but a port official told Ship & Bunker they had not formally received a request to that effect.
MFMs are a more accurate means of measuring bunker deliveries. Traditional tank soundings taken with a measuring tape are vulnerable to both accidental and deliberate misreporting of delivered volumes. The 'cappuccino bunkers' effect, where air bubbles in the oil give the impression of more fuel having been delivered than was actually the case, has been a longstanding problem in the industry, and one that can be eliminated by the use of MFMs.
The city-state's Maritime and Port Authority (MPA) imposed the mandate for fuel oil deliveries from the start of 2017 and extended it to cover distillates from July 2019.
Singapore used to be the bunkering location with the biggest problem of quantity disputes before it introduced its MFM mandate.
The timeframe between the Northwest European mandate first being announced in October 2022 and its coming into effect in January 2026 is similar.
But Singapore also subsidised the installation of the meters, offering a lump sum of $$80,000 ($63,500 as of April 2014) per fuel oil bunker delivery vessel to help cover the cost.
The authorities at Rotterdam and Antwerp-Bruges have no intention of offering a similar subsidy, sources told Ship & Bunker.
In the years after imposing its MFM mandate Singapore had some cases of the systems being tampered with, but the city-state's tough rules for bunker suppliers and barge operators meant the MPA could ban those responsible from operating in its waters, discouraging other companies from attempting the same thing.
Belgian and Dutch national legislation already sets in place the European Union's Measurement Instrument Directive, and the International Organization of Legal Metrology's (OIML) R 117 (2019) recommendations.
While a licensing system exists for bunker barge operators in Northwest Europe, some have questioned whether the system is robust enough to ensure the integrity of MFM operations.
