Genoa lays the twelfth caisson of the new breakwater
At the end of August, production of the largest caissons will begin: 67 metres in length. The Tronds Barge 33, a semi-submersible barge, goes into operation. The work is being realised by the PerGenova Breakwater consortium, led by Webuild, on behalf of the Western Ligurian Sea Port Authority.

In Genoa, the twelfth caisson of the Nuova Diga foranea was positioned today. The work is being carried out by the PerGenova Breakwater consortium, led by Webuild, on behalf of the Western Ligurian Sea Port Authority.
The construction site
.At the end of August, work will begin on the construction of the biggest barge, measuring up to 67 metres long, 35 metres wide and 33 metres high. The Tronds Barge 33, a 110-metre long and 45-metre wide semi-submersible barge capable of sinking up to 20 metres below the water level, will be used to build them. This sinking capability allows the barge deck to be lowered below the waterline, facilitating launching and caisson handling operations.
There are currently more than 450 people involved in the project, including direct and third-party personnel, and with the planned new activities there will be an increase in employment, also linked to the doubling of shifts.
The future dam
.With a final length of 6.2 kilometres and an laying depth of 50 metres - the deepest ever experienced in Europe for a breakwater - the new infrastructure will make the port of Genoa accessible to new generation ships up to 400 metres in length, strengthening the role of the Ligurian port of call in the Rhine-Alps Corridor of the TEN-T network.
The work, developed entirely in the open sea, is taking shape on an already consolidated seabed with more than 2,200 tonnes of gravel laid to which should be added 41,000 submerged columns, amounting to a total of 478,000 linear metres already completed, more than half of the total length envisaged by the project.
