Inner Oslo Fjord

About the project

Statnett invested in the Inner Oslofjord project to ensure security of power supplies for customers in central Eastern Norway by replacing two existing links built in 1958 and 1975. The new cable systems also added value by enabling the exchange of power with Sweden.

The project covered two new links: One to connect Solberg in Hurum and Brenntangen in Vestby Municipality (Solberg-Brenntangen) and the other, Filtvet in Hurum and Brenntangen in Vestby Municipality (Filtvet-Brenntangen).

The project was due for completion in 2018.

Nexans' solutions

Nexans designed and manufactured two new 420 kV subsea cable systems. Each link comprised seven individual cables based on Nexans state-of-the-art XLPE (cross-linked polyethylene) cable technology installed at a maximum water depth of 220 m.
