Project will provide a 170kV power cable connection crossing a fjord of almost nine kilometers in Northern Norway at a water depth of 200 meters. 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 EPCI contract comprises engineering, procurement, construction and installation of the cable systems based on Nexans well-proven XLPE subsea cable technology, plus single-core XLPE underground cables for the land-based sections, with accessories including terminations, joints, earthing and anti-corrosion systems.
Contract Details
Description
Nexans was awarded an EPCI contract by Statnett to deliver the new Hadselfjord high-voltage power link between Fiskebøl and Melbu in Northern Norway. The scope covered engineering, procurement, manufacture and installation of two 170 kV three-core XLPE submarine cable systems across the fjord, along with associated underground land cable sections and accessories such as terminations, joints, earthing and anti-corrosion systems. The subsea cables incorporate integrated fibre-optic elements for communication and distributed temperature sensing to support reliable operation. Cables are manufactured at Nexans’ high-voltage subsea factory in Halden, with the fibre-optic elements produced at its Rognan plant, and installation was scheduled to start in 2022. The project replaces a 1977-vintage link and is intended to strengthen security of electricity supply and support future electrification for around 50,000 residents in the Lofoten and Vesterålen island archipelagos. The contract value exceeds EUR 18 million and primarily relates to the construction phase, including detailed engineering and commissioning of the new cable system.
