Port facilities at Punta Langosteira

La Coruña, Spain

The work consists of a 3,400- m long rubble-mound breakwater with a protective mantle formed by 150- ton blocks and head formed by blocks of high density of up to 195 ton. The crest wall crown is at a height of +25 m. This is a unique breakwater, not only because of the depth reached (40 m) but also due to the severe maritime climate in the area, with a wave height design Hs, 140 years = 15 m. The works also consist of the execution of a  443- m long T-shaped structure made up of 12 caissons, the first phase of a 495- m sloping breakwater and a 940- m long dock for dry bulk made up of 23 caissons, which are 16,25 m wide at the shaft. A 150- HA reclaimed land esplanade is also constructed. The resulting sheltered water area is 230 HA.
