Statnett
Description
Implenia Norway, part of the Implenia Group, was contracted by Statnett in 2015 to deliver ground and tunnel works for the Norwegian segment of the North Sea Link interconnector. Its scope covered excavation, blasting and tunnelling for the onshore HVDC cable corridor, together with the construction of quays and landslide protection works needed for cable landfalls and access along the route. These civil works prepared the alignment between inland Norwegian locations and the fjords/North Sea, enabling subsequent installation of the North Sea Link onshore and nearshore cable sections.
