Fuel supply operators and shipping companies operating in Vigo Port have a new regulatory framework to manage. The Port Authority of Vigo has published the particular conditions of service that regulate the bunkering service in its facilities, with a relevant novelty: for the first time, the conditions expressly incorporate biofuels and synthetic fuels alongside traditional petroleum derivatives.
The resolution, dated 23 March 2026 and published in the BOE on 12 May 2026 (reference BOE-A-2026-10311), is not a minor change: it defines the conditions under which any company can provide the fuel supply service to vessels in Vigo, and establishes the requirements that must be met to access this activity.
What does this regulation establish?
The particular conditions of service published by the Port Authority of Vigo comprehensively regulates the fuel supply service to vessels in its facilities. The document covers three categories of fuels:
| Fuel type | Description |
|---|---|
| Conventional fuels derived from petroleum | Fuel oil, marine gas oil and other traditional derivatives used in propulsion and auxiliary services of vessels |
| Biofuels | Fuels of biological origin suitable for marine use, in line with EU decarbonization requirements |
| Synthetic fuels | Fuels produced through non-fossil processes (e-fuels and similar), included in the conditions as a response to the energy transition of the maritime sector |
Companies interested in providing this service must comply with the technical, economic and operational requirements established in the conditions. Although the published summary does not detail the specific amounts of bonds, fees or charges, the full BOE text contains the specific conditions that each operator must demonstrate to obtain authorization.
The inclusion of biofuels and synthetic fuels is neither optional nor cosmetic: it reflects the adaptation of Spanish port regulations to European environmental requirements for maritime transport decarbonization, a process that the EU is accelerating with regulations such as FuelEU Maritime.
Economic and operational impact
This conditions of service has direct consequences in two areas:
For bunkering operators: Any company wishing to supply fuel to vessels in Vigo Port must comply with the technical, economic and operational requirements of the new conditions. This may involve investments in infrastructure, certifications or capabilities to handle biofuels and synthetic fuels, in addition to conventional fuels. Companies that already operated under a previous regime must verify whether their current situation complies with the new conditions.
For shipowners and shipping companies: The new framework also regulates access to supply from the demand side. Shipping companies calling at Vigo and needing to refuel with alternative fuels (biofuels or synthetic) will now have a clear framework on how and under what conditions they can do so. This is especially relevant for fleets that are already adapting their vessels to lower-carbon fuels to comply with European regulations.
The regulatory opening to alternative fuels can also generate business opportunities for new operators specialized in biofuels or marine e-fuels that want to establish themselves in Vigo Port.
Who does it affect?
- Current bunkering operators in Vigo Port: must review whether their authorization and operational capabilities comply with the new conditions.
- New fuel supply operators: wishing to access the Vigo Port market must comply with the technical, economic and operational requirements of the conditions to obtain authorization.
- Shipowners and shipping companies with regular calls at Vigo: affected by the conditions under which they can refuel, especially if they already use or plan to use biofuels or synthetic fuels.
- Marine fuel logistics and trading companies: operating or wishing to operate in the Vigo Port environment.
- Maritime sector advisors and consultants: who must guide clients on regulatory compliance in Spanish ports.
Practical example
A bunkering company that currently supplies marine gas oil to fishing and merchant vessels in Vigo Port operates under the previous regime. With the publication of this conditions, it must review whether its current authorization covers the new conditions established or whether it needs to renew or expand it.
Furthermore, if that same company detects that several of its shipping clients are beginning to demand biofuels to comply with European decarbonization regulations, the new conditions offer it the legal framework to expand its activity to that type of fuel in Vigo Port, provided it demonstrates the corresponding technical and economic requirements.
On the other hand, a shipping company operating coastal routes with calls at Vigo that has already adapted part of its fleet to biofuels can now refuel with that type of fuel in the port with a clear regulatory framework, something that previously could generate operational uncertainty.
What should companies do now?
- Download and read the complete conditions: Access the full text of the resolution in the BOE (BOE-A-2026-10311) to learn the exact technical, economic and operational requirements demanded of operators.
- Verify the status of current authorization: Bunkering operators already active in Vigo Port must check whether their current authorization is compatible with the new conditions or whether they need to adapt it.
- Evaluate capacity to operate with biofuels and synthetic fuels: If the company does not currently have infrastructure or certifications to handle these fuels, this is the time to assess whether investment in that capacity opens business opportunities in Vigo Port.
- Consult with a specialist advisor in port regulations: Given that the conditions establish specific technical and economic requirements, it is advisable to seek specialized advice before submitting any authorization request.
- Shipowners: review current supply contracts: Shipowners and shipping companies with fuel supply contracts in Vigo Port must verify that their agreements with bunkering operators are compatible with the new regulatory framework.
- Monitor the entry into force date: The exact date of application is not specified in the published summary. It is essential to consult the full text and be alert to communications from the Port Authority of Vigo to avoid breaches due to ignorance of the deadline.
Frequently asked questions
What types of fuel does the new Vigo Port conditions regulate?
The conditions regulates three categories: conventional fuels derived from petroleum, biofuels and synthetic fuels. The first category includes traditional marine fuel oil and gas oil. Biofuels are biological origin fuels suitable for marine use. Synthetic fuels are produced through non-fossil processes, such as e-fuels.
Do current bunkering operators in Vigo need to renew their authorization?
The resolution does not explicitly state that all current authorizations are automatically revoked. However, operators must verify that their current authorization is compatible with the new conditions. If there are significant changes in requirements, renewal or adaptation may be necessary. It is advisable to contact the Port Authority of Vigo directly.
