Description
Nexans was contracted in 2015 to design, manufacture and install the North Sea Link HVDC cables on the Norwegian side of the UK–Norway interconnector. The company produced approximately 500 km of mass‑impregnated non‑draining (MIND) ±525 kV HVDC cables at its Halden plant and undertook cable laying from Hylsfjorden through the fjords to the North Sea, including 2.8 km of twin cables in Lake Suldalsvatnet at depths over 200 m. Using a purpose‑built floating platform on the lake and its cable‑lay vessel Nexans Skagerrak offshore, Nexans installed and buried the cables and later jointed its Norwegian section to Prysmian’s UK‑side cables in 2021. The work covered both subsea and inland Norwegian segments, delivered on behalf of the North Sea Link project.
