- J Murphy & Sons Limited awarded Nexans with a contract worth over €35 million, to supply the land export cable for the Triton Knoll offshore wind farm.
- Nexans will supply cross-linked polyethylene (XLPE) insulated alternating current (AC) cables required to connect the offshore wind farm to the UK grid.
- With a capacity of approximately 860 MW, the Triton Knoll wind farm will have the capability to supply the equivalent of over 800,000 UK households per year with renewable electricity.
Nexans Wins Multimillion Euro Contract at UK’s Triton Knoll Offshore Wind Farm
The UK offshore wind farm market is continuing to lead the way in meeting Europe’s growing demand for renewable wind energy. With nearly 30 per cent of the country’s electricity generated by clean sources in 2017, the UK looks to maintain its world leader position in renewables with the launch of major new projects such as the Triton Knoll offshore wind farm, being developed by Innogy Renewables UK Ltd, in partnership with J-Power and Kansai Electric Power. Within the framework of the project, Nexans has been awarded a contract worth over €35 million by Triton Knoll’s onshore cable installation lead contractor J Murphy & Sons Ltd to supply the land export cable and accessories in order to connect the wind farm to the UK grid.
Located around 30 km off the coast of Lincolnshire, Triton Knoll 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. This method was chosen by the partners to minimize setup constraints and further reinforce the safety and quality of the installation. To support the Triton Knoll project, Nexans will continue strengthening its local UK pool of experienced staff including project, site and QHSE managers as well as chief jointers.
Murphy’s CEO 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 added: “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.”
“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,” said Laurent Guillaumin, Business Development Director – Offshore Wind Europe at Nexans. “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.”
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.

Scottish and Southern Electricity Networks (SSEN) and Balfour Beatty have successfully energised the connection for Dorenell wind farm in Moray. The wind farm connection, which will add capacity for a further 220 MW of renewable energy to the GB transmission system, has seen the deployment of composite poles, the first time this innovative technology has been used on the GB transmission system.
Project Development & Execution
The Scottish Government has set an ambitious target for renewable energy resources to meet 100 percent of the country’s gross annual electricity consumption by 2020. Large onshore wind farms will play a key role in meeting this target, such as the 88 megawatt (MW) Kype Muir wind farm, where Nexans has just completed a project to provide a 16 km 132 kilovolt (kV) underground grid connection for SP Energy Networks.
Business & Finance
- Nexans and Marais Laying Technologies Australia, a Tesmec Group subsidiary, have partnered in a consortium to provide a complete collector cable service for Australia’s Stockyard Hill Wind Farm;
- The consortium has been awarded a contract worth over 12 million euros (around 20 million AUD) by the project’s contractor SNC-Lavalin to design, manufacture, supply, install and test 275 km of 33 kV collector cables for the 530 MW onshore wind farm that will be the largest in the Southern Hemisphere;
- The project relies on a unique design methodology for wind and solar farm collector networks developed to boost cost savings of the wind farm and supported by Nexans Research Center of Lyon;
- Trenching and laying of the 33 kV power cables, fiber optics and earthing cables for the first collector group of 13 turbines were started by Marais Laying Technologies Australia in the fourth quarter of 2018.
