Sète: Floating Breakwater and Passenger Ferry Reception Pontoon

Port Sud de France – Sète: Floating breakwater and reception pontoon for passenger vessels

At Port Sud de France (Sète), a solution was required to effectively protect the marina from heavy wave action generated by commercial fishing traffic, ensuring the safe coexistence of fishing and recreational fleets.
MSI constructed one of the largest floating breakwater installations in Europe, measuring nearly two kilometers in length. The project combines an initial section consisting of SF1230 modules arranged in parallel, reaching 6 meters in width and intended for vessel mooring, and a second section comprising a 4-meter T400 floating breakwater, guided by internal piles and also equipped for finger mooring within the protected area.
The solution provides excellent wave attenuation along with effective and durable marina protection.
