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

June 29,2005 - Genoa breakwater, launch of the tenth caisson

Tenth caisson sunk and first half of columns now completed, with 34,000 columns built up to a depth of 50 metres.
New Genoa Breakwater: the infrastructure that transforms the port takes new steps forward.
Work in progress for the construction of the New Breakwater, the largest intervention to strengthen Italian ports and the deepest dam in Europe, is carried out by the PerGenova Breakwater Consortium led by Webuild on behalf of the Western Ligurian Sea Port Authority.

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.

Webuild eleventh caisson positioned for the new Genoa Breakwater

Genoa, July 19, 2025 – The eleventh mega caisson of the new Genoa Breakwater has been positioned on the seabed off the coast of the city. This is one of the most complex maritime engineering projects currently under construction in Europe, built by the PerGenova Breakwater consortium led by Webuild on behalf of the Western Ligurian Sea Port Authority.

READ THE PRESS RELEASE

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.
