Caisson Installation Advances for Genoa Breakwater Infrastructure

The PerGenova Breakwater Consortium, led by Webuild, has successfully installed the 24th concrete caisson for Genoa's New Breakwater project. Commissioned by the Western Ligurian Sea Port Authority, this installation marks the continuation of marine construction after the offshore structure surpassed one kilometer in length.

Caisson Specifications and Marine Operations
The latest installed caisson measures 40 meters in length, 25 meters in width, and 18.70 meters in height. The structure was transported from the concrete manufacturing facility in Vado and positioned onto the consolidated seabed. The marine operations were executed to align with established safety standards while managing variable weather and sea conditions throughout the installation process.

Supply Chain and Seabed Consolidation
The ongoing infrastructure development requires synchronized operations between land-based manufacturing and offshore installation. Activities are continuously coordinated between the concrete production site in Vado and the marine vessels conducting seabed consolidation works. This logistical framework supports the sequential placement of the caissons required to complete the maritime barrier for the Italian port system.

In modern marine engineering, breakwaters in deep water or on soft seabeds are frequently constructed using cellular concrete caissons rather than traditional rubble-mound designs. Caissons are pre-fabricated, hollow concrete structures that are towed out to sea and subsequently sunk into position by filling their internal cells with water, sand, or gravel. For the Genoa New Breakwater—which is being constructed offshore to allow larger post-Panamax container ships to maneuver safely within the port—seabed consolidation is a critical prerequisite. This geotechnical process typically involves driving thousands of gravel columns deep into the ocean floor to increase the load-bearing capacity and prevent uneven settlement of the massive concrete structures once they are submerged.
