France, 2015 – 2016
Within the scope of the project for extending the port of Cherbourg, work carried out by Bouygues Travaux Publics Région France (DTP) and its consortium consists in constructing a 1.8-km enclosure dyke comprising 250,000 tonnes of riprap, in 5- to 6-tonne units, to contain the 5 million m3 of dredged material making up the future quay levels.
The long-term aim of the total 39-hectare extension is for the port to be able to create spaces for implanting offshore wind turbines, thus becoming a benchmark port for the construction, maintenance and operation of future wind farms.
