ABERDEEN, UK– Prysmian PowerLink S.r.l has subcontracted Canyon Offshore Ltd. for cable trenching services on the North Sea Link interconnector.
The 1,400-MW subsea HVDC system with cables linking the UK and Norway when complete is said to be the world’s longest submarine interconnector.
Prysmian PowerLink S.r.l is manufacturing and installing the two parallel HVDC cables for National Grid and Statnett (North Sea Link Interconnector) between Blyth, England and Kvilldal, Norway.
Estimated to cost €1.5-2 billion ($1.7-2.3 billion), North Sea Link is the first interconnector between the UK and Norway.
Canyon Offshore will trench about 900 km (559 mi) of the two interconnector HVDC cables which will have been laid onto the seabed by Prysmian PowerLink S.r.l.
The operations will be performed over four annual campaigns beginning in 2018.
