The New Genoa Breakwater Project

The New Genoa Breakwater is a globally speaking one-of-a-kind work, for its engineering complexity and dimensions, but also because it is built offshore, fully at sea, without the need to interrupt port activities. It will rest on the seabed at a 50-metre depth, one of the deepest worldwide for breakwaters, developing, in total, over a 6.2 km line.

The new infrastructure sets itself apart for the innovative technology used in the project and for the attention placed on sustainability, ensured by systems aimed at maximising circular economy, while also foreseeing the possibility of reusing and transforming inert materials.

February 18, 2025 – A seventh caisson has been installed for Genoa’s new breakwater. PerGenova breakwater consortium has deployed a workforce of around 450 employees across multiple fronts

Around 450 people, including 150 working directly at sea, are engaged on multiple fronts in the construction of Genoa’s new breakwater. Despite challenging weather conditions, the seventh caisson has now been installed. This key infrastructure project, crucial for the future of the Ligurian capital’s port, is being carried out by the PerGenova Breakwater consortium, led by Webuild on behalf of the Western Ligurian Sea Port Authority.

January 18, 2025 – New Genoa Breakwater: sixth caisson installation now completed.

Winter doesn't stops the construction site off the coast of Genoa. The work continues without interruption! Work in progress for the construction of the New Breakwater, the largest intervention to strengthen Italian ports and the deepest dam in Europe.

New Genoa breakwater: PerGenova breakwater consortium at work to repair damaged caisson during most recent intense storm, no impact on work's timeline

Genoa, January 30, 2025 – The PerGenova Breakwater Consortium building the new Genoa Breakwater informs that during the last and most recent intense storm that hit the Ligurian Sea in these past days, with waves reaching 7 metres in height in the construction site area, the fifth caisson of the new breakwater was damaged in part on its superior part, during filling operations. The caissons, which have not been damaged further, are stable and located in their project design position.

The Consortium said it is already repairing the caisson. Reparations of the damages incurred in the "wave screen" windows that do not have a structural function for the caisson's stability, do not impact in any way the regular carrying out of the activities planned for the new Breakwater, which in fact are being carried out on more fronts as per work plan.

The largest upgrading intervention for the Ligurian port area in the last 25 years

The new breakwater will enlarge transit and manoeuvring areas for ships inside the port, so that it can welcome a greater number of ships, becoming an infrastructure capable of allowing the Ligurian system and Italy to grow in competitiveness. This project will positively impact Genoa, its port, and the whole of Italy. It will create growth from when it is first built: in fact, 1,000 people will be newly employed for the work (directly and indirectly hired).. The work has been commissioned by the Western Ligurian Sea Port Authority, and belongs to the Extraordinary Programme to relaunch the Port of Genoa.
