N-Sea Group Awarded Contract to Repair Cable for Gwynt y Môr Offshore Wind Farm
Dutch subsea services specialist N-Sea Group has been awarded a contract to repair one of the four cables that connect the Gwynt y Môr offshore wind farm in the Irish Sea to the National Grid.
The offshore wind farm, with a capacity of 576MW, is located off the coast of Wales and has been operational since 2013. The wind farm features 160 wind turbines of 3.6MW each, and GYM OFTO owns the transmission assets connecting the wind farm to the National Grid.
N-Sea’s scope of work includes replacing a 5 km section of 132kV export cable from the onshore transition joint bay towards the offshore platform. The project involves pulling ashore the new cable through a horizontal directional drill duct under a railway, dredging the shore approach, jointing, testing the new cable, and burial. This marks the third repair project N-Sea has undertaken for this client.
The company will utilize its in-house survey, unexploded ordnance (UXO), and data center divisions to engineer and deliver a new route for the cable, along with providing as-built data upon completion of the project.
The repair campaign is scheduled for the summer and will be conducted using N-Sea’s cable repair vessel, Curo. The vessel is equipped with an eight-point mooring system for maintaining position during operations, even in strong tidal conditions. Additionally, it has beaching capabilities to work safely near the landfall location.
