530 metres below sea level.
That is now the world record depth for a 420 kV HVAC subsea cable installation.
Together with Statnett, we have completed the expansion of the 420 kV high-voltage subsea power link across the Fensfjord in Western Norway.
This crossing doubles transmission capacity between Haugsvær and Lindås, helping reinforce power reliability for Bergen and surrounding industrial areas.
Delivering this required precise ex*****on in demanding conditions:
→ 7.8 km of high-voltage subsea cable across the fjord
→ Installation depth of 530 m
→ Fjord slopes reaching 55 degrees
→ Marine operations led by CLV Nexans Skagerrak
This project is a strong example of what it takes to deliver high-voltage subsea cable infrastructure in challenging environments — safely, reliably and in close coordination with our customer.
