Nuova Diga Foranea di Genova – PerGenova Breakwater

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.

PROJECT UPDATES

February 6, 2024: Works continues with the construction of more than 1320 submerged columns. Final unexploaded ordnance search phase to begin

Works proceed rapidly to build the new breakwater, with a new milestone during these days: that of laying 1 million tonnes of gravel along the seabed, offshore from Genoa, reaching 40% of the laying activities. A quantity that allowed building, since May 2023, more than 1,320 submerged gravel columns, concomitantly safeguarding the marine ecosystem. While at the same time, the activities to search for the underwater unexploded ordnances continue to advance, 70% of which have been in fact already completed.

Activities at the construction site of the new Genoa breakwater continue unabated. To date, more than 600,000 tons of gravel have already been laid on the seabed off the city. In the "Test Camp 1" area, the 862 gravel columns have been completed, and the installation activities of the geotechnical monitoring instrumentation are beginning.

Genoa, May 4, 2023 - Laying of the first stone for the New Genoa Breakwater

The Western Ligurian Sea Port Authority and the Pergenova Breakwater consortium led by Webuild, launched the construction works for the New Genoa Breakwater in the presence of the Italian Minister of Infrastructure and Transport Matteo Salvini.

The first stone was laid for the New Genoa Breakwater, a one-of-a-kind work for its engineering complexity, dimensions and overall benefits for Genoa and Italy. The day opened with an institutional meeting hosted in the "Sala delle Compere" hall in Palazzo San Giorgio, with a live connection for the operations at sea of the first jet of gravel to consolidate the seabed which will support the new breakwater.

The event was attended by Italian Minister of Infrastructure and Transport Matteo Salvini, Deputy Italian Minister of Infrastructure and Transport Edoardo Rixi, Admiral Inspector and Liguria Maritime Director Sergio Liardo, Liguria Region President Giovanni Toti, Genoa Mayor Marco Bucci, Western Ligurian Sea Port Authority Chairman and Extraordinary Commissioner for the project Paolo Emilio Signorini, and Webuild CEO Pietro Salini.

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.
