The Seine-North Europe Canal is a central link in the Seine-Escaut waterway system. It will enable wide-gauge barges to travel between France, Belgium and the Netherlands, reaching an annual transport volume of 15 million tonnes of goods. The Société du Canal Seine-Nord-Europe asserts that its ambition is to make this canal a flagship project for environmentally sustainable transport, and the energy transition, which is also in tune with local issues. By replacing a million lorry journeys a year, it will significantly reduce greenhouse gas emissions.
Two public transhipment platforms are currently under construction at Pimprez and Ribécourt-Dreslincourt. Eventually, they will be linked to the local road network and then to the rail network.
EcoSheetPile™ Plus sheet piles for the Ribécourt and Pimprez quay walls: almost 4,000 tonnes of CO2-eq saved
EcoSheetPile™ Plus low carbon-emissions steel sheet piles were selected for these projects. They are produced in Belval (AZ sheetpiles) and Differdange (HZ) from 100% recycled steel, powered exclusively by electricity generated from renewable wind or solar sources.
The EcoSheetPile™ Plus range is part of the ArcelorMittal Group's XCarb® brand, which brings together all its low-carbon steel products and activities. This product range benefits from an Environmental Product Declaration (EPD) issued by the Institut Bauen und Umwelt e.V. (IBU) in Germany, and based on a life cycle analysis carried out in accordance with standard NF EN 15804.

A life cycle assessment (LCA) 
for sheet piles at the Pimprez and Ribécourt-Dreslincourt quay walls has been carried out by the Design Department of ArcelorMittal Sheet Piling in Esch to calculate greenhouse gas emissions during their manufacturing. It was carried out on the basis of three official EPDs: (1) EcoSheetPile™ Plus made through the electrical route with renewable electricity, (2) EcoSheetPile™ made through the electrical route with standard energy mix, and (3) products from steel made through the primary route from coal and iron ore. [https://sheetpiling.arcelormittal.com/sustainability/epd-lca/
It was calculated that these nearly 2,000 tonnes of low carbon-emissions sheet piling prevented the emission of around 4,000 tonnes of CO2-eq. compared with sheet piles that would have been produced by the primary route using iron ore and coal (716 tonnes of CO2-eq. compared with 4,724 tonnes of CO2-eq. for the primary route). The exclusive use of electricity from renewable sources reduces greenhouse gas emissions by 29% compared with the standard energy mix for the electric furnace process in Luxembourg (716 tonnes of CO2-eq. compared with 1,007 tonnes).

About the project
|Ribécourt-Dreslincourt quay|| || |
The Ribécourt-Dreslincourt quay consists of a double curtain of sheet piling over a length of 150 m. The platform is approximately 20 m wide.
921 tonnes of EcoSheetPile™ Plus sheet piling in XCarb® recycled and renewably produced will be delivered for this part of the project.
Double wall dock: 965 t of steel, including
- 160 m of AZ 13-770 main wall: 205t
- 160 m of AZ 12-770 anchor wall: 70t
- 320 m of UPN double U-channels: 30t
- Tierods and accessories: 25 t
- 235 m of a combined wall HZ 880M A and AZ 24-700: 646 t
Similar in design to the Ribécourt-Dreslincourt quay, the Pimprez quay is 50 m longer and its eastern connection is 30 m longer. It also features a combined wall of 1,015 tonnes of EcoSheetPile™ Plus type HZ-M / AZ sheet piling, from the XCarb® recycled and renewably produced range.
Double wall dock: 1,080 t of steel, including
215 m of AZ 13-770 main wall: 250 t
