SPRETEC

What SPRETEC does

SPRETEC (Société Pour la Réalisation d'Ensembles TEChniques) is a French mechanical engineering services firm founded in December 1987 and headquartered in Seyssins, France. The company operates as a wholly-owned subsidiary of the ARTELIA Group, having joined the engineering and consulting organization in 2011. SPRETEC provides specialized mechanical engineering studies, calculations, design, diagnostics, execution studies, expertise, inspection, and project management (maîtrise d'œuvre) services to large infrastructure operators, industrial firms, government entities, and defense organizations. Its core technical capabilities center on finite element analysis, thermal calculations, vibratory dynamics, fatigue analysis, and seismic calculations applied primarily to pressurized conduits (penstocks), gates, valves, dams, hydroelectric installations, port and maritime structures, nuclear facilities, offshore installations, civil engineering works, cable car systems, and research/testing facilities. The firm works to multiple French and international standards (CODETI, CECT, ASCE, AWWA, Eurocodes 3) and invests in proprietary R&D around seismic analysis and fluid-structure interaction.

SPRETEC's revenue model is B2B project-based engineering services with no publicly disclosed pricing. The go-to-market relies on direct engagement with enterprise and government clients, professional networks in the engineering and hydroelectric sectors, and indirect access to international mandates via the ARTELIA group. Active reference projects include the Tolla dam, Vichy dam renovation, Eaux-Bonnes hydroelectric modernization, Strasbourg/Gerstheim/Fessenheim lock gates, the Tour Eiffel north elevator renovation, the École Centrale de Nantes basin extension, the DGA hydrodynamic test facility, the Gilboa penstock in Israel, and the Ars-en-Ré flood gate, among others. Documented clients span EDF, Bouygues, Eiffage, Schneider, the Ville de Perros-Guirec, the Syndicats Mixte Ports de Normandie, and the Direction Générale de l'Armement (DGA). Geographic reach is primarily France with documented projects in Greece, Israel, Spain, and Nigeria. The firm holds 11–50 employees and is privately held with no independent listing.

Core offering

SPRETEC delivers mechanical engineering studies, advanced calculations, diagnoses, and maîtrise d'œuvre (project management) for critical infrastructure including hydroelectric dams and penstocks, ports and maritime works, nuclear facilities, defense installations, space-related structures, rope-driven people transport, and civil engineering works. The firm couples consultancy and design services with an in-house experimental hall and portable diagnostic instrumentation to validate designs and assess existing assets.

Product overview

SPRETEC is a mechanical engineering company offering a comprehensive portfolio of engineering services rather than a software product. The company provides specialized engineering studies, calculations, and expertise across multiple industrial sectors including hydroelectricity, ports and maritime, nuclear, defense, space, and infrastructure. The core offerings include mechanical studies, fatigue analysis, diagnostic services, execution studies, expertise, inspection, and project management (maîtrise d'œuvre). The company operates as part of the ARTELIA group and serves clients in France and internationally since 1987.

Functional benefit

Products and services

• Mechanical engineering studies and calculations (Études et calculs en mécanique) Core mechanical engineering studies encompassing thermics, vibratory dynamics, seismic calculations, fluid-structure interaction (IFS), fatigue and fracture mechanics. Delivered to operators, constructors, and public-sector clients in the energy, nuclear, defense, space, port/maritime, and rope-transport sectors to validate and design critical infrastructure.
• Mechanical diagnoses (Diagnostics mécaniques) On-site diagnostic studies of mechanical behavior using portable equipment (machine, floating, roll-wave flow measurement, pressure, movement, vibration sensors) for asset owners needing to assess the integrity of operating infrastructure in hydroelectric, nuclear, port and rope-transport contexts.
• Project management / Maîtrise d'œuvre Full project management services (maîtrise d'œuvre) for infrastructure projects, including complex multi-stakeholder construction works in dams, penstocks, industrial piping, ports and civil engineering.
• Hydroelectric and dam infrastructure engineering Engineering services for dams, hydroelectric facilities, penstocks and pressurized conduits, covering study, calculation, and maîtrise d'œuvre with R&D investment in seismic-fluid-structure calculation programs (CASHIMA, ALIZE).
• Port and maritime works engineering (Ouvrages portuaires et maritimes) Mechanical engineering studies and project management for port and maritime works, serving operators and builders of harbors, quays, locks, and coastal installations.
• Industrial piping engineering (Tuyauteries industrielles) Engineering studies and calculations for industrial piping and pressurized conduits, addressing mechanical integrity, fatigue and fracture mechanics for operators of energy and process installations.
• Nuclear and defense engineering services Mechanical engineering studies, calculations, and validation for nuclear installations, defense-related structures, and SPACE-domain programs, applying safety-critical calculation methodology and physical testing.
• Civil engineering works (Génie civil) Civil engineering study and project management services complementing SPRETEC's mechanical engineering portfolio for infrastructure projects.
