Port of Rotterdam, Port of Antwerp-Bruges Introduce Bunkering Change

From 1 January 2026, all bunker vessels operating in the ports of Rotterdam and Antwerp-Bruges must use a Mass Flow Meter (MFM) when delivering residual distillates (fuel oil and diesel) and biofuels. This system measures exactly how much fuel goes from the bunker ship to the seagoing vessel. The aim is to make the bunker market in both ports more reliable, efficient, and transparent. Once the MFM system is implemented, it must also be certified.

The port authorities of Rotterdam and Antwerp-Bruges have observed frequent issues with bunker fuel deliveries. As a result, the use of the MFM system on board bunker vessels is becoming mandatory. The ports of Rotterdam and Antwerp-Bruges apply the same requirements for MFM systems as other leading ports around the world. These requirements are defined in the international ISO 22192 standard. However, Rotterdam and Antwerp-Bruges cannot adopt all parts of this standard directly due to European regulations.

However, the objective remains the same: in both ports, the use of an MFM system is mandatory, just as it is in the Port of Singapore. The systems used in Singapore are also required in Rotterdam and Antwerp-Bruges.

The ports of Rotterdam and Antwerp-Bruges also require that the general rules and procedures for bunkering using the MFM system align with those set out in the ISO standard. In this respect as well, there is no difference from other ports where an MFM system based on ISO 22192 is mandatory.

The bunker surveyor continues to play a vital role in bunkering, even with the mandatory use of an MFM system. However, the role will change. It is important for the bunker surveyor to stay informed about developments related to the MFM system. The International Bunker Industry Association (IBIA) offers training on the MFM system in both Rotterdam and Antwerp. If a bunker surveyor is engaged, the ports recommend selecting one who is well trained and qualified.

The bunker permit, including the MFM system, is mandatory. Regulations must be complied with. Supervisors will carry out inspections both randomly and in response to signals from the market on board bunker ships. Please note: it is mandatory to certify the MFM system and submit it to the harbour master or port captain before 1 January 2026. In the event of violations, fines may be imposed or the bunker licence may be revoked.
