Port of Rotterdam & Port of Antwerp-Bruges mandate the use of MFM

As of 1 January 2026, the use of a Mass Flow Meter (MFM) system on board bunker vessels will be mandatory for the delivery of residual distillates (fuel oil and diesel) and biofuels in the ports of Rotterdam and Antwerp-Bruges. 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.
