Fouré Lagadec

What Fouré Lagadec does

Fouré Lagadec is a French industrial services company headquartered in Le Havre, founded in 1922, and operating today as a wholly-owned subsidiary of Groupe Snef. The company designs, manufactures, installs and maintains complex pressure equipment, mechanical sub-assemblies, piping, boilermaking structures and naval systems, operating as a turnkey contractor and industrial systems integrator that takes projects from engineering studies and equipment design through manufacturing, on-site installation, commissioning and ongoing facility maintenance. Specialized capabilities span an in-house mechanical and metallurgical testing laboratory (including hot tensile testing to 800°C and impact testing down to -196°C), COFREND/ASNT-TC-1A-qualified non-destructive testing (NDT), 3D scanning with a FARO arm at 12 µm accuracy, low-speed balancing up to 1,500 kg, and proprietary marine stabilizer systems (retractable and non-retractable fins, anti-drift fins, bow thruster tunnel covers).

The company's revenue mix combines multi-year managed-service and maintenance contracts (TotalEnergies Normandy Platform since 1974; ongoing EDF and Framatome nuclear maintenance), project-based equipment design and one-time fabrication (heat exchangers, reactors, columns, tanks, valves), and shutdown-engineering professional services for refineries, petrochemical facilities, nuclear plants and power generation. Pricing is quote-based and not publicly disclosed; distribution is exclusively direct B2B enterprise sales supported by an 18-office French network plus four international operations enabling proximity to major client sites in the UK, Romania, Spain, Turkey and Africa. Customers are large industrial enterprises across nuclear (EDF, NNB Generation/Hinkley Point C, Framatome), energy and petrochemical (TotalEnergies, ExxonMobil, Adisseo, North Atlantic), and naval/marine (Neoline, merchant and naval fleets). Since joining Snef Group in 2018, Fouré Lagadec has executed a sustained roll-up: ACM-ACR (2021, ESPN nuclear pressure equipment), Navtis/SOBEC (2022, naval maintenance), Vochelet Usinage/UCMI (2022-2023, 5-axis precision machining), CLECIM (2025, industrial expertise) and CLID SYSTEMES (2026, robotic and automated systems).
