Nexans wins cables contract for 860 MW Triton Knoll offshore wind farm

Nexans has announced that it has been awarded a contract worth over EUR35 million (US$40.2 million) by J Murphy & Sons Ltd to supply the land export cable and accessories required to connect the Triton Knoll offshore wind farm to the UK grid.

Located around 30km off the coast of Lincolnshire, Triton Knoll is being developed by Innogy Renewables UK Ltd, in partnership with J-Power and Kansai Electric Power. J Murphy & Sons Ltd is the onshore cable installation lead contractor.

The wind farm has a planned installed capacity of approximately 860 MW and, once operational will be capable of generating enough renewable electricity to supply over 800,000 UK households.

To export the energy generated by the wind farm to the grid, Triton Knoll will rely on Nexans’ 220 kV land export cables, which will transmit the power over a total distance of around 57 km from landfall near Anderby to the new Triton Knoll substation at Bicker Fen. Nexans will supply HVAC cable with two circuits each comprising three individual XLPE-insulated AC cables with an aluminum conductor.

Jointing works will be carried out by the teams of Nexans Subsea and Land Systems Business Group using purposely designed cable-jointing containers positioned on the joint bays built by J Murphy & Sons Ltd.

The HVAC export cable will be manufactured by Nexans Germany facility in Hanover, Germany, with the first cable drums scheduled for delivery in the first quarter of 2019, followed by jointing works planned for second quarter 2019. Commissioning and testing of the cable system is expected to take place in summer 2020.
