Nexans wins Oslofjord contractProjects and Operations // July 26, 2010
Nexans has been awarded a Euros 104 million contract by Statnett, Norway’s state-owned power grid, to design, manufacture and install the new Oslofjord II submarine high-voltage power link, replacing the existing cables which were installed over 30 years ago.
The new Nexans cables will help increase transmission capacity to almost 3,000 MVA, as well as ensuring a high level of continuity and reliability for a power link that plays a vital role both in Norway’s transmission grid and in facilitating the transmission of power between Norway and Sweden.
The Oslofjord II link, to be installed over a 13km route across the fjord, will consist of 3 x 420 kV XLPE submarine power cables and 6 x 420 kV paper insulated submarine cables. The XLPE installation will be the longest of its kind in the world, beating the previous length of 2.4km established by Nexans in the Ormen Lange project.
Nexans will deliver a total of 117km of 420 kV submarine cable in nine lengths, including end terminations. Each cable will be 13km long. The cables are to be manufactured at Nexans’ plants in Norway and Japan and will be installed at a water depth of 200 to 250 metres by Nexans’ vessel, Nexans Skagerrak, working in combination with other vessels.
The first section of the installation will be completed in 2011, with the final delivery taking place during August 2012.
