Strengthening water infrastructure for a safer, more sustainable future
To replace the aging floodgates on its La Vanelle dam, EDF was looking for an industrial partner capable of guaranteeing the safety and extending the service life of the structure.
The aim of the project was to optimize hydraulic management and enhance resilience to climatic hazards, while modernizing the infrastructure to improve its overall performance.
The EDF La Vanelle dam project reflects our expertise in managing large-scale steel structures. Thanks to our proven technical expertise, we were able to meet the challenges posed by the hydraulic and environmental constraints specific to this type of infrastructure.
Eiffage Métal's scope of activity
Eiffage Métal took charge of all operations relating to the replacement of the floodgates:
- Project management
- Design and technical studies
- Manufacture of the gates, measuring 20 m x 11 m x 11 m, at our Fos-sur-Mer plant, and application of anti-corrosion protection
- Installation on customer site and commissioning
- Design, manufacture, dismantling and replacement of the complete drive system (motors, gearboxes, extensions, indicators, clutches, brakes, etc.)
- Complete drafting of operating procedures and manufacture of equipment required for the work.
Key figures
