Further multi-million pound UK cable deal done for Hornsea Project Two
By Grimsby Telegraph | Posted: 3 Sep 2018
UK-based JDR Cables has won a multi-million pound contract to supply inter-array cables and termination work for Ørsted’s record-breaking offshore wind farm, Hornsea Project Two.
When operational in 2022, the wind farm will supply clean electricity to over 1.3 million homes, and surpass its sister project Hornsea One, as the world’s largest offshore wind farm.
The contract includes 100km of inter-array cables, all to be assembled at the company’s Hartlepool facility. It follows a deal done last month with Wrexham-based Prysmian Group.
Inter-array cables link turbines together, and carry the clean electricity generated by the turbines to an offshore substation, which converts it to a higher voltage for transmission to shore, where it will connect to the grid at North Killingholme.
As the farms get larger and turbines bigger, the spread widens, increasing the demand for the cabling, with multiple suppliers engaged due to the massive lengths needed, the timescales set. It also mitigates risks and costs.
The project is Ørsted’s first in the UK to use 66kV for its array cables, having used 33kV for previous projects. Using cables with a higher voltage helps to reduce electrical losses during transmission.
Patrick Harnett, engineering, procurement and construction director for Hornsea Project Two at Ørsted, said:
“This contract builds on experience from previous projects including Race Bank offshore wind farm, which we opened earlier this year, and Hornsea Project One, currently in construction.
“As our wind farm projects have grown in size, and distance from shore, so too have the contracts we place within the supply chain. The technology we use is also changing as we innovate to build these projects at massively lower cost of electricity into the UK’s grid. We are proud to sign this contract with a UK-based firm, and look forward to continuing our collaboration.”
Once built, with pre-assembly and blade manufacture in Hull, it will be operated and maintained from Grimsby, where Ørsted is establishing its East Coast Hub.
Richard Turner, chief executive of JDR, said: “Hornsea Project Two is a 1.4GW offshore wind project that will be built at the lowest ever price seen in the UK. This incredible achievement is being enabled by organisations like JDR and Ørsted working collaboratively to push the technical boundaries of offshore wind projects – making them more economic than ever before and leading the way for future developments.”
