COMMISSION IMPLEMENTING DECISION (EU) 2026/712

| Official Journal of the European Union | EN L series ---|---|--- * * * | 2026/712 | 26.3.2026 ---|---|--- COMMISSION IMPLEMENTING DECISION (EU) 2026/712 of 24 March 2026 authorising Belgium to derogate from technical requirements of Annexes II and V to Directive (EU) 2016/1629 of the European Parliament and of the Council for a tugboat ‘HAVENSLEEPBOOT 21’ (notified under document C(2026) 1910) (Only the Dutch and French texts are authentic) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive (EU) 2016/1629 of the European Parliament and of the Council of 14 September 2016 laying down technical requirements for inland waterway vessels, amending Directive 2009/100/EC and repealing Directive 2006/87/EC (1), and in particular Article 25(1), point (b), thereof, After consulting the Committee established by Article 7 of Council Directive 91/672/EEC of 16 December 1991 on the reciprocal recognition of national boatmasters’ certificates for the carriage of goods and passengers by inland waterway (2), Whereas: (1) | On 29 April 2021, Belgium notified the Commission of its intention to derogate from certain technical requirements of Annexes II and V to Directive (EU) 2016/1629 for a tugboat ‘HAVENSLEEPBOOT 21’. The tugboat has only recently become operable which is why it is appropriate to adopt the implementing decision which allows the issuing of a Union certificate for that craft. ---|--- (2) | The proposed derogation concerns the use of dual-fuel internal combustion engines for the tugboat ‘HAVENSLEEPBOOT 21’. Those engines serve as the propulsion of the vessel and combust methanol and marine gasoil as fuels up to a ratio of 70 % methanol and 30 % marine gasoil. ---|--- (3) | Using dual-fuel methanol / marine gasoil engines for the vessel’s propulsion is a promising technology in the context of deploying clean energy and alternative fuels for vessels, reducing greenhouse gases and potentially pollutants. ---|--- (4) | The proposed derogation encourages innovation and enables the use of new technology through the pilot implementation of dual-fuel methanol / marine gasoil engines in inland navigation. Such pilot implementation of dual-fuel methanol / marine gasoil engines is part of the technology deployment, which is the only way to initiate the possible serial production phase. ---|--- (5) | Technical requirements for inland navigation vessels are laid down in the European standard set up by the European committee for drawing up Standards in the field of Inland Navigation (‘CESNI’). This standard is referred to as ES-TRIN. At the time the tugboat was conceived and constructed, the applicable ES-TRIN, as set out in Annex II to Directive (EU) 2016/1629, did not include specific provisions for the use of dual-fuel methanol / marine gasoil in the vessel’s propulsion engines. Based on the insights gained by the development of the pilot vessel at hand, dedicated rules for the usage of methanol onboard of craft have been included in ES-TRIN 2025/1 (3) which only became applicable by reference in Annex II to Directive (EU) 2016/1629 on 1 January 2026. ---|--- (6) | In the absence of regulatory provisions for the combined use of methanol and marine gasoil for the vessel’s propulsion engines, especially at the time when the vessel is conceived and constructed, it is necessary to ensure an adequate level of safety of the proposed use of a propulsion system. ---|--- (7) | The technical documentation submitted with the request to derogate (‘the technical documentation’) has been prepared by Lloyd’s Register, which is a recognised classification society for inland waterway vessels under Article 21 of Directive (EU) 2016/1629. Those technical specifications were developed taking into account the relevant provisions of Chapter 30 of ES-TRIN 2023/1 (Special provisions applicable to craft equipped with propulsion or auxiliary systems operating on fuels with a flashpoint equal to or lower than 55 oC) and Annex 8 to ES-TRIN 2023/1 (Supplementary provisions applicable to craft equipped with propulsion or auxiliary systems operating on fuels with a flashpoint equal to or lower than 55 oC). ---|--- (8) | Based on the technical documentation, the Working Group on technical requirements of CESNI (‘Working Group’) examined the combined use of methanol and marine gasoil as fuels for the vessel’s propulsion engines and the safety measures in the proposed derogation. The results of that technical examination are set out in the technical specifications annexed to this Decision which is based on the document CESNI/PT (20) 21 rev. 3. ---|--- (9) | The conclusion of the technical examination by the Working Group was that the operation, bunkering and maintenance of the system can be safely undertaken having regard to the planned measures and procedures set out in the technical documentation. It is, therefore, possible to state that an adequate level of safety referred to in Article 25(1), point (b), of Directive (EU) 2016/1629 is ensured, provided that the conditions set out in the Annex are met. Therefore, the proposed derogation can be granted. ---|--- (10) | However, in order to support the development of possible future provisions for the type-approval of internal combustion engines running on methanol, in accordance with Regulation (EU) 2016/1628 of the European Parliament and of the Council (4), and in addition to the reporting requirements laid down in point 8 of document CESNI/PT (20) 21 rev. 3, reports on formaldehyde emissions should also be provided. As practical experience with formaldehyde emissions of such type of engines is lacking, Belgium should in that context take into account its obligations arising from Council Directives 89/391/EEC (5) and 98/24/EC (6) and Directive 2004/37/EC of the European Parliament and of the Council (7). ---|--- (11) | The proposed derogation concerns issuance of a Union inland navigation certificate for trial purposes incorporating new technical specifications that derogate from Annexes II and V to Directive (EU) 2016/1629. Such derogations are to be granted only for a limited period, which in this case should be five years as from the adoption of this Decision, ---|--- HAS ADOPTED THIS DECISION: Article 1 Derogations from technical requirements of Annexes II and V to Directive (EU) 2016/1629 for a tugboat ‘HAVENSLEEPBOOT 21’ with a unique European vessel identification number 06503824 regarding the issuance of a Union inland navigation certificate for trial purposes incorporating new technical specifications are allowed to the extent and subject to the conditions set out in the Annex to this Decision. Those derogations are without prejudice to Union’s occupational safety and health legislation, in particular to the obligations stemming from Directives 89/391/EEC, 98/24/EC and 2004/37/EC. Article 2 This Decision shall apply for 5 years after its adoption. Article 3 This Decision is addressed to the Kingdom of Belgium. Done at Brussels, 24 March 2026.
