In the Port of Le Havre, the foundation works for the lock access channel breakwater “la chatière” are nearing completion. According to HAROPA PORT, this major stage of the maritime construction project consists of building the submerged base of the structure, which will support the installation of the Accropode units.
Started in mid-February 2026, the foundation works involve constructing the submerged base of the future lock access channel breakwater.
This foundation forms the structural base of the breakwater. It is made up of sand and gravel materials specifically suited to maritime conditions, part of which comes from the beneficial reuse of dredged materials from the future navigation channel. These materials are placed using a diffuser barge supplied through a floating pipeline connected to a vessel responsible for transporting them to the site.
Nearly 800,000 m³ of materials have been placed along the 1,800-metre-long breakwater, without any disruption to the port’s commercial traffic, HAROPA PORT said.
The works are being carried out by Terélian and its consortium partner DEME, under the supervision of HAROPA PORT.
