New version of the ES TRIN 2025/1, a boost for electric power in inland navigation

Version 2025/1 of the European standard âeuros¯ES TRINâeuros¯ (European standard laying down technical requirements for inland waterway vessels) will come into force on January 1âeuros¯2026. This update marks a significant change: the redundancy requirements in chapterâeuros¯11 of the text, dedicated to electric propulsion systems, have been relaxed, which could simplify and speed up the transition to cleaner propulsion systems.

Fewer constraints for electrics

Until now, electric propulsion systems on inland waterway vessels, especially passenger ships, have been subject to stringent redundancy requirementsâeuros¯: several power sources, separate circuits, etc. The new version of ESâeurosTRIN provides river boat owners with a more flexible technical framework for these redundancies. With this new version of ESâeurosTRIN, river boat owners now have a more flexible technical framework for these redundancies, making the choice of electric or hybrid propulsion more economically viable. According to a representative of the DGITM (Direction générale des Infrastructures, des Transports et de la Mer), speaking at the AFBE (Association française du bateau électrique) Technical Day, this regulatory change could encourage owners of freight boats or river services to opt for electric drives.

A real opportunity for river transport

By facilitating the use of electric power, these new regulations will enable waterway operators to reduce their operating costsâeuros¯: less fossil fuel, fewer heavy technical constraints, and greater compatibility with energy transition objectives. This may also encourage orders for new sailboats or electric-powered vessels in inland areas, and stimulate port owners or builders specializing in this segment.

A few precautions to keep in mind

However, some industry players are warning that, even if constraints have been eased, compliance remains a challenge, particularly for vessels already in service. Switching to electric propulsion still requires investment (batteries, infrastructure, adaptation of onboard systems) and, for many, limited feedback. What's more, although the requirements have been relaxed, they have not been eliminated: equipment ownership, maintenance and certification are still essential.

With this 2025/1 version of the ESâeurosTRIN, Europe is sending out a clear signal: electric propulsion in inland navigation is no longer just a project for the future, but is becoming a legally viable option. For shipyards, shipowners and suppliers in the boating and river sectors, this is a window of opportunity not to be missed.
