Nexans has won a €35m contract to supply onshore cabling for the 860MW Triton Knoll offshore wind farm off the east coast of England.
The deal, with lead onshore cable installation contractor J Murphy & Son, is for 220kV wires with two circuits each comprising three individual XLPE-insulated AC cables with an aluminium conductor.
Jointing works will be carried out by Nexans Subsea and Land Systems Business Group using cable-jointing containers positioned on joint bays built by J Murphy & Sons.
The partners said they chose this method to minimise set up constraints.
The cable will be manufactured by Nexans’ facility in Hanover in Germany.
The first cable drums are 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.
J Murphy chief executive John Murphy said: “The cable route presents an exciting engineering challenge for us and we’ve worked diligently and intelligently to create better engineered solutions that will allow us to deliver it with minimum disruption.
“We’re very proud to be working on Triton Knoll offshore wind farm and with its project team, who are so firmly committed to leaving a positive legacy in Lincolnshire, an aim we share at Murphy.”
Triton Knoll project director Julian Garnsey said: “I am pleased to welcome Nexans on board with Triton Knoll via this key contract with Murphy, coming as the project enters full onshore construction.
“The onshore electrical system is clearly critical to delivering wind power from Triton Knoll’s world leading turbines into UK households, and Nexans’ cables will be at the heart of that.”
Nexans offshore wind Europe business development director Laurent Guillaumin said: “We are delighted to win the Triton Knoll contract, which continues Nexans’ strong track record in UK wind projects and extends our fruitful partnership with Murphy.
“This new success showcases Nexans’ capacity to help customers meet the ongoing challenge of reducing the installed and operating cost per MWh of their wind farms thanks to the competitive design of Nexans’ cables as well as the technical expertise and jointing know-how of our teams.”
