Project presentation

Context & challenges

The Aquarius project is part of the modernisation of the Sète–Frontignan oil depot, a strategic site for regional petroleum product supply. It implements a new import chain from the offshore berth to the depot, enabling a range of vessel sizes and ensuring flow security in a port with strong operational constraints. BP France entrusted Entrepose Contracting, as lead company of a VINCI subsidiaries consortium, with designing and delivering an integrated solution compliant with regulatory and HSE requirements, combining marine works, offshore and onshore pipelines, and process facilities tied into existing infrastructure.

Technical challenges & responses

• Marine works & dredging : dredging of about 800,000 m³ and construction of two piled steel jetty platforms with twelve mooring dolphins and berthing equipment, while maintaining port traffic at Sète–Frontignan.
• Pipelines & process : construction of a 24-inch onshore steel pipeline over 3.4 km, including trenchless crossing under SNCF railways by micro-tunnelling, installation of a 1.4 km offshore pipeline, and installation of process networks on the marine platform for tie-in to the depot.
• Multi-subsidiary synergies & HSE: coordination by Entrepose Contracting of VCMF, Geocean, Spiecapag Régions France, and Francilis expertise to optimise interfaces, phasing, and testing, supported by enhanced HSE measures to limit construction risks, nuisance, and impacts on the coastal environment.
