The new Genoa breakwater project, led by the PerGenova Breakwater consortium with Webuild at the helm, has made significant progress with the first caisson laid at a depth of 25 m.

The first caisson, built on the floating construction sites at Vado Ligure port, measures 21.7 meters in height, 40 meters in length, and 25 meters in width, weighing 10,000 tons. Larger caissons will reach up to 67 meters in length. Constructing a caisson takes about 20 days and involves 50 people. The process includes positioning a temporary metal structure on a floating platform, pouring concrete in layers, and gradually raising the formwork. Once completed, the caisson is transported to its designated location using tugboats, and then sunk by filling it with water and stone. On-site, it is finished by adding a superstructure and safeguarding wall.

Alongside the laying of the first caisson and preparation for the next mega blocks, the Genova Breakwater consortium is progressing with other aspects of the project. Over 1.4 million tons of gravel have been placed on the seabed to solidify the breakwater's foundations, and more than 4,000 submerged columns have been constructed. Additionally, work on the Vado Ligure construction site's protection barrier is underway, involving five smaller caissons. These efforts aim to widen the port, allowing entry for larger ships up to 400 meters long. The project is managed by a consortium led by Webuild (40%), with Fincantieri Infrastructure (25%), Fincosit (25%), and Sidra (10%).
