Genoa breakwater passes key installation milestone

The latest phase of the marine construction programme was completed by the Webuild-led PerGenova Breakwater Consortium on behalf of the Western Ligurian Sea Port Authority.

The consortium said the installation marked further progress on one of Italy’s most strategically significant port infrastructure developments, with teams operating continuously between land and sea to maintain construction momentum.

Engineering feat

The newly installed caisson measures 40 metres long, 25 metres wide and 18.70 metres high.

It was positioned on the seabed through a series of coordinated marine civils operations carried out under strict safety procedures despite challenging weather and sea conditions.

According to Webuild, organisational efficiency across the construction site and the full operational capacity of project teams have been central to maintaining progress on the breakwater development.

The project forms part of wider investment in Genoa’s port infrastructure aimed at strengthening the competitiveness and operational resilience of the Italian port system.

Webuild described the scheme as one of the country’s most important marine construction projects currently under development. The company is globally active in large-scale infrastructure sectors including sustainable mobility, water infrastructure and green buildings.

Previous stages of the project involved the use of the semi-submersible Tronds Barge 33 to install large caissons offshore. Earlier reports stated that some caissons used for the breakwater measured 67 metres in length, 35 metres in width and 33 metres in height.

The Genoa breakwater project continues to advance through complex offshore engineering and marine civils activity as construction progresses further into open sea conditions.
