N-Sea has been awarded a contract by Gwynt y Môr OFTO for a further repair to one of the four export cables that connect the Gwynt y Môr Wind Farm to the National Grid. Gwynt y Môr is a 576MW offshore wind farm located off the coast of Wales, United Kingdom.
The wind farm, operational since 2013, comprises 160 wind turbines of 3.6MW each. Gwynt y Môr OFTO owns the transmission assets linking the wind farm to the National Grid.
The N-Sea scope of work includes replacing a 5km section of 132 kilovolt export cable from the onshore transition joint bay towards the offshore platform. This will involve pulling ashore the new cable through a horizontal directional drill duct under a railway, dredging the shore approach, jointing, testing, and burial of the cable. N-Sea’s in-house survey, unexploded ordnance (UXO) and data centre teams will engineer and deliver a new cable route, including as-built data upon completion.
N-Sea is preparing for the repair campaign during summer 2025. Operations will be carried out using the company’s cable repair vessel, Curo. The Curo is equipped with an eight-point mooring system to maintain position during operations, even in strong tidal conditions, and features beaching capabilities to allow safe access close to the landfall location, essential for nearshore, shallow-water repair work.
