Replacement 420 kV power link across the Oslofjord will feature
the world`s largest high-voltage XLPE submarine cable installation
Nexans (Paris:NEX), the worldwide leader in the cable industry, has been awarded
a 104 million Euro contract by Statnett, Norway`s national main grid owner and
operator, to design, manufacture and install the new Oslofjord II submarine
high-voltage power link thus replacing the existing cables installed over 30
years ago which have reached the end of their service-life. The new Nexans
cables, which transmission capacity will reach 3,000 MVA, will ensure 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 13 km 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 largest of its kind in the
world, each cable 13 km long, beating the previous length of 2.4 km established
by Nexans in the Ormen Lange project.
Nexans will deliver a total of 117 km of 420 kV submarine cable in 9 lengths,
including end terminations. 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` own vessel, the C/S Nexans Skagerrak, among other vessels. The first
section of the installation will be completed in 2011, with the final delivery
taking place during August 2012.
“Oslofjord II is a very important project for us in the Norwegian market. We
have worked with Statnett on numerous occasions and are both proud and pleased
that they have placed their trust in us once again”, says Krister Granlie,
Nexans Managing Director Umbilicals & Submarine High Voltage Business Group.
The existing Oslofjord cables, based on an oil-filled design, were manufactured
and installed by Nexans in a series of projects between 1959 and 1980.
