Prysmian to develop submarine power cable links for Hornsea Project Two in the UK, the world’s biggest offshore wind farm

Prysmian Group, world leader in the energy and telecom cable systems industry, has been awarded a new contract by Ørsted Wind Power A/S to supply submarine inter-array cables for what will become the world’s biggest offshore wind farm.

Hornsea Project Two, located 89 km off the Yorkshire coast, will be able to supply well over 1.3 million homes with green, renewable electricity once it becomes operational in 2022. Prysmian Group has been focusing on this growing market segment leveraging on its product innovation and new installation assets and capabilities.

Prysmian Group will be responsible for the design, manufacture, supply, termination and testing of the inter–array submarine cables system that will connect 110 of the 165 wind turbines and the offshore substation platform. The project involves more than 300 km of 66 kV inter-array cables with EPR insulation and single wire armouring systems plus all related accessories.

All the submarine cable cores will be produced at the Group’s centre of excellence located in Wrexham, Wales, UK, while the armouring and assembling process will be performed in Drammen, Norway.

The cables are due to be delivered in 2021.

“We are proud to support Ørsted in this important challenge, providing the UK market with the highest quality cables locally manufactured for the next generation of UK offshore wind farms. The development of grid infrastructures for the transmission and distribution of electric power from renewable sources is of strategic importance. With this contract, we are proving our capability to also offer competitive inter–array cable technology, as well as our undisputed leadership in export cables,” stated Alessandro Panico, Sales Team Manager Offshore Wind, Prysmian Group.
