The Port of Hanstholm, located on the exposed North Sea coast of Denmark was expanded during the years 2017–2020. The port expansion features a new large western breakwater in 9–13.5 m water depth with 15 t to 32.5 t Cubipods as its main protective armour. The breakwater head towards the harbour entrance is established by a large prefabricated concrete caisson (40 × 22 × 18 m). The breakwater was extensively tested in the 3D wave basin at Aalborg University, which revealed some remarkably benefits of Cubipods over other concrete armour units. Detailed design of the breakwater, the largest ever built in Denmark, was carried out by COWI A/S for the marine contractor Per Aarsleff A/S, who won the port expansion design–build contract. This paper presents the design consideration for the new western breakwater, including considerations of different breakwater concepts and details on why Cubipods in one layer was eventually chosen as the preferred armour for the breakwater. In addition, the paper describes the laboratory testing of the breakwater and its performance under severe wave conditions. The paper also touches on some of theinnovative methods which were developed by the contractor to keep a high armour layer production rate under challenging wave conditions. [ABSTRACT FROM AUTHOR] |
