Nexans has landed a major order from Statnett to supply and install a new high-voltage subsea power link crossing Hadselfjord in the far north of the country. The project is vital to strengthen the security of supply for a population of around 50,000 people in the Lofoten and Vesterålen island archipelagos.
The Hadselfjord cable project is vital for Statnett as the current cable, installed in 1977, has exceeded its technical design life. Nexans will upgrade the link by installing two 170kV submarine cable systems covering a route of approximately 8.8km at a maximum water depth of 200m.
The cable route extends across Hadselfjord between Fiskebøl and Melbu in Vesterålen. The EPCI contract comprises engineering, procurement, construction and installation of the cable systems based on Nexans well-proven cross-linked polyethylene (XLPE) subsea cable technology. The three-core cables will have an integrated fibre-optic element for both communication and Distributed Temperature Sensing (DTS). The contract also includes single-core XLPE underground cables for the land-based sections of the link, together with accessories such as cable terminations, cable joints, earthing systems and anti-corrosion systems.
Nexans will manufacture the Hadselfjord cables at its specialised subsea cable factory in Halden, Norway, and produce the fibre optic elements at its own plant in Rognan in northern Norway. The cables have a design lifetime of 40 years, and installation is expected to commence in 2022.
