Technical requirements


ES-TRIN and inland navigation vessel certificates

Since 2015, the CESNI Committee has regularly updated and published the European Standard laying down Technical Requirements for Inland Navigation vessels (ES-TRIN). This standard lays down the uniform technical requirements necessary to ensure the safety of inland navigation vessels. It is available in four languages (German, English, French, Dutch) and brings together in a standardised way the requirements previously contained in directive 2006/87/EC and in the Rhine vessel inspection regulations. It contains provisions on inland navigation vessel construction and equipment, special provisions for certain categories of vessels such as passenger and container vessels, provisions on the model of inland navigation vessel certificate as well as instructions on how to apply the technical standard.

References to ES-TRIN are now included in the legal frameworks of the EU and the CCNR (respectively directive (EU) 2016/1629 and Rhine vessel inspection regulations). The Danube Commission also decided in 2017 to recommend the standard in its international instruments and the International Sava River Basin Commission intends to create a reference to the standard in its legal framework. In other words, ES-TRIN has been established, with great effort, as the centrepiece and baseline for the technical requirements for inland navigation vessels in Europe and has contributed to the reinforcement of governance at the European level.

As a reminder, a vessel operating on EU waterways or Rhine must carry either a Union inland navigation certificate or a Rhine vessel inspection certificate. Both certificates are issued by the competent national authorities (inspection bodies) and confirm the full compliance of the vessel with the technical requirements (in particular ES-TRIN). Once again, the objective of these technical requirements is to guarantee a high level of safety in inland navigation, thereby also protecting the environment and the people on board.

List of inspection bodies for the issuance of inland navigation vessel certificates

Dedicated website for the lists of equipment and firms

ES-TRIN contains provisions on the approval of installations and equipment, as well as installation firms and technical services. Such approvals are the responsibility of the national authorities under the ES-TRIN and associated regulatory frameworks (i.e. Rhine vessel inspection regulations or directive (EU) 2016/1629).

CESNI launched the website with the following objectives:

  • to enable its members to exchange information on the approvals awarded at national level,
  • to make it easier to inform the public about approved equipment and recognised firms, and
  • to facilitate the work of inspection bodies and enforcement authorities.

Furthermore, this website contains information for public consideration about the inspection bodies and competent authorities for technical requirements for inland navigation vessels.

Database for the application of the technical requirements for inland vessels

The database contains questions, comments and interpretations for which the Working group on technical requirements (CESNI/PT) has given a coordinated response or conclusion. This data results from the actual application of the technical requirements of the ES-TRIN (or earlier texts).

Explanatory notices of the amendments introduced in the new edition of ES-TRIN

CESNI publishes explanatory notices to document the needs, alternatives and consequences associated with the amendment introduced by the new edition of ES-TRIN.

Frequently asked questions (FAQ) regarding the application of the ES-TRIN and the NRMM Regulation to engines fitted to inland navigation vessels

CESNI and EUROMOT have developed a FAQ document to help those involved with the inland waterways transport sector to understand and interpret the applicable requirements to engines in the light of the new requirements for non‐road mobile machinery (NRMM) as well as ES-TRIN.

Guide for the procedure to marinise NRE type machinery and equivalent engines like truck engines (EURO VI) and checking the eligibility for installation of these engines into inland navigation vessels

CESNI has also produced a guide aiming to clarify the administrative procedure for the recognition and installation of marinised engines (NRE and Euro VI) in inland navigation vessels within the framework of Regulation (EU) 2016/1628 and the ES-TRIN.

Guide to possible derogations from technical requirements of the ES-TRIN for traditional craft

To ease the implementation of ES-TRIN to traditional craft, CESNI has developed a guide to possible derogations from technical requirements.

Guide for the hull survey report model file

Measurements and condition of the vessel’s hull and hull equipment shall be subject of a report in accordance with the model “Hull Survey Report” or equivalent. This model provides the list of minimum data required for hull survey report and is not a mandatory format.


Leaflet on deliberation on derogations and equivalences of technical requirements of the ES-TRIN for specific craft

The CESNI Secretariat is regularly requested by the public for information on the procedure for derogations and equivalences from technical requirements. In order to ensure transparent and comprehensive information, considering both EU and CCNR legal frameworks, the CESNI decided to publish a leaflet on its website. The procedure described allows to gain experience with pilot projects (e.g. alternative fuels) and actively supports innovation and greening of the fleet.

Study – Evaluating the energy requirement of inland vessels using energy efficiency indices

The Working Group CESNI/PT decided in June 2020 to publish the following evaluation study which was carried out by the German delegation in the framework of the task PT-26 of the CESNI work programme 2019-2021. This does not prejudge the development of policies by national or international regulatory bodies.
