The Seine – Nord Europe Channel (CSNE in French) consists of the execution of a 107 km river infrastructure between the Oise region in France and the Dunkerque-Escaut channel.


This channel constitutes a high gauge waterway link that was missing in the European grid, between the Seine river basin in the north of France and the Northern Europe. Located over the North Sea – Mediterranean corridor, the Seine – North Europe channel is the central link of the Seine – Escaut project, currently one the prioritised projects in Europe.




Setec, in a partnership with Royal Haskoning DHV (project’s lead engineering consultant), supports the project owner in the project execution and its steering.


Setec will provide with the services listed below for a duration of 12 years, from creation of the project’s programme, requirements and objectives, to the first year after the commissioning.
