The Port System Authority of the Central Tyrrhenian Sea announced the start of the extension and strengthening works of the Duca d'Aosta breakwater in the port of Naples, a work maritime transport among the most complex and expensive ever built in the Campania airport. The first phase of the intervention, aimed at restoring a part of the dam that guarantees safe access to the incoming and outgoing ships that were partially damaged from a series of storm surges in recent years, predicts the reconstruction of the wave wall, and then subsequently extended the protection infrastructure of the port along its entire length of 2.6 kilometers, adding another 200 meters of bulwark. This first tranche, worth 92.7 million euros, provides for strengthening interventions and involves 1.1 kilometres of dam on a total work of about 121 million euros which is included in a broader intervention ("Extension and strengthening of the Duca D'Aosta breakwater") financed for a total of 150 million with complementary funds to the National Plan of Recovery and Resilience.

The work that has just started - explained the secretary general of the Port Authority, Giuseppe Grimaldi - are spread over a length of 800 meters, on the sea-side front, where a cliff covered with a mantle in "tetrapods", specific for sea walls. Interventions are also planned restoration, repair and local consolidation of existing structures for all 2.6 kilometers of the "Duca" dam d'Aosta" and the "Thaon de Revel" wall. The works must be completed by 30 June 2026.

Meanwhile, at the end of last month, in the port of Salerno the Port System Authority of the Central Tyrrhenian Sea has the construction site for the start of the consolidation works and functional adaptation of the west side of Pier 3 January of the Campania airport which must be completed by the end of June 2025. Pier 3 Gennaio is mainly used for loading, unloading and handling of various goods, as well as being a transit area for quay cranes.

To the west of Pier 3 Gennaio bulkheads will be installed composed of large diameter tubular metal poles about 25 meters long, which make the structural elements load-bearing, alternating with metal sheet piles in the shape of a "z" which achieve the closure between the main elements. The new quay bulkhead, tied at the head with anchor rods, will be fixed close to the existing quay, 383 meters long, and then filling the cavity with concrete between the quay and the bulkhead. For reasons related to stability of the quays the activities must be carried out from the sea with the help of suitable maritime means. On the bulkheads will be made of a correa beam in reinforced concrete on where quay furnishings such as bollards will be installed mooring, fenders and climbing ladders. The intervention It also includes the formation of a type of semi-flexible, specific for port areas, over the entire length of the quay. Main objectives of the works: to fill the any caves present at the foot of the quays caused by the action of the forward and aft propellers of the ships, so as to restore the uniformity of stresses on the soils of foundation; eliminate the problem of the run-off of the embankment that comes out through the cracks between the boulders constituting the current bank walls with consequent anomalous deformation of the Squares; adapting the quays - built between 1969 and 1985 - to the current seismic regulations and the consequent greater loads to the increase in port traffic; finally, allow the Planned deepening of the seabed, as planned by the Technical Functional Adaptation of the Port Master Plan of Salerno.
