    Canyon Offshore to trench world’s longest submarine interconnector

    Contracts, Tenders and Rates // July 21, 2017

    Canyon Offshore Limited in Aberdeen has been awarded a contract for the provision of offshore cable trenching services on the North Sea Link Interconnector.

    The 1.400MW subsea HVDC system with cables linking the UK and Norway when complete will be the world’s longest submarine interconnector.

    The multi-million pound subcontract was awarded by Prysmian PowerLink, who are manufacturing and installing the two parallel HVDC cables for National Grid and Statnett (North Sea Link Interconnector) between Blyth in England and Kvilldal in Norway.

    Estimated to cost €1.5-2 billion, North Sea Link is the first interconnector between the UK and Norway and will contribute to a more climate friendly energy system.

    Canyon Offshore’s award will require the trenching of approximately 900km of the two interconnector HVDC cables which will have been laid onto the seabed by Prysmian PowerLink.

    Management of the operations, which will be performed over four annual campaigns commencing in 2018, will be provided from Canyon Offshore Limited’s Aberdeen base.
