Rotterdam, Netherlands – Europe’s largest bunkering ports, Rotterdam and Antwerp-Bruges, will implement a new regulatory framework from 1 January 2026, marking a significant step toward enhanced transparency, standardisation, and accountability in marine fuel delivery operations.
This regulatory milestone introduces mandatory requirements designed to modernize bunkering processes and align the ARA region with leading global standards in maritime fuel measurement, licensing, and compliance.
From the start of 2026, all bunker vessels operating in Rotterdam and Antwerp-Bruges must:
- Be equipped with certified Mass Flow Meter (MFM) systems to ensure precise measurement of delivered fuel volumes.
- Hold a valid bunkering licence with full compliance to all operational, safety, and environmental standards.
- Follow new procedural compliance measures, including oversight by qualified independent bunker surveyors who will verify and audit the fuel delivery process.
These rules apply equally to deliveries of residual distillates and biofuels, signaling a holistic approach that encompasses all marine fuel types, including those critical for decarbonisation.
Certified mass flow meters (MFMs) now mandatory
One of the most significant elements of the new framework is the mandatory use of certified MFMs. These devices provide:
- Real-time, highly accurate measurement of fuel quantities transferred during bunkering operations.
- A tamper-resistant, auditable system that drastically reduces longstanding disputes over delivered versus received volumes.
To ensure compliance, all MFMs must:
- Be certified by an authorised and recognised body.
- Be registered with the Harbour Master of the respective port.
- Be fully installed and operational by 1 January 2026.
This mandate mirrors Singapore’s pioneering MFM regulations introduced in 2017, which have been widely credited with enhancing bunkering transparency and trust.
Continued requirement for valid bunkering licences
In addition to mandatory Mass Flow Meters, bunker suppliers operating in the ports of Rotterdam and Antwerp-Bruges must hold a valid bunkering licence to conduct any fuel deliveries involving residual distillates or biofuels.
Port authorities have emphasized that this is not a formality but a core component of the regulatory framework. Licence holders must demonstrate full compliance with operational, safety, and environmental requirements at all times.
To ensure enforcement, the ports will conduct:
- Routine audits to verify adherence to procedural standards.
- Unannounced inspections, triggered by risk signals or complaints.
- Ongoing regulatory monitoring to uphold transparency and market integrity.
This dual approach — combining technological controls via MFMs with strict licensing oversight — is designed to reinforce trust in the supply chain, eliminate malpractice, and raise the overall standard of fuel delivery operations in Europe’s leading bunkering hubs.
The evolving role of bunker surveyors
While MFMs automate quantity measurement, the role of independent bunker surveyors remains essential, evolving from manual gauging to technical oversight. Their responsibilities will include:
- Verifying the integrity and seal of the MFM system prior to fuel transfer.
- Confirming that the MFM’s calibration certificates are valid and up-to-date.
- Auditing bunkering procedures to ensure compliance with new operational protocols.
- Detecting any signs of tampering or procedural deviations that could compromise accuracy.
Ports strongly recommend employing surveyors trained and certified in MFM auditing practices.
Inclusion of biofuels: advancing sustainability and traceability
Importantly, the regulation applies not only to traditional fossil fuels but also to biofuels, reflecting the ports’ commitment to maritime decarbonisation and sustainability.
This ensures:
- Accurate measurement and traceability of biofuels alongside conventional fuels.
- Alignment with EU regulatory frameworks such as the FuelEU Maritime initiative and Renewable Energy Directive II (RED II).
- Verification of sustainability claims and lifecycle emissions reporting.
By incorporating biofuels, Rotterdam and Antwerp-Bruges demonstrate leadership in supporting green shipping and reinforcing market confidence in alternative marine fuels.
International harmonization and global competitiveness
Although European regulatory nuances prevent full adoption of ISO 22192 (the global bunkering metering standard), both ports have committed to aligning their MFM protocols closely with its principles.
- MFM systems certified and accepted in Singapore will be valid in Rotterdam and Antwerp-Bruges, ensuring interoperability.
- This alignment supports shipowners and bunker suppliers operating globally, facilitating seamless fuel procurement across major hubs.
The move places the ARA ports in direct competition with Singapore and other leading bunkering centers by emphasizing operational transparency, accuracy, and trustworthiness.b.
Broader industry impact and outlook
The implementation of these rules will have wide-ranging consequences:
- Bunker suppliers face initial capital expenditure to procure, certify, and install MFMs but will benefit from reduced disputes, streamlined processes, and enhanced reputation.
- Shipowners and charterers will gain confidence in receiving exactly the fuel volumes contracted, improving voyage planning, emissions tracking, and cost management.
- Bunker Surveyors will transition into highly skilled technical auditors, adding an essential layer of oversight to safeguard the integrity of automated metering systems.
Ultimately, these regulatory changes mark a turning point in maritime bunkering, driving a new era of accountability, efficiency, and sustainability in one of the world’s busiest marine fuel hubs.
