Jones Bros Civil Engineering UK has completed the installation of around four miles of high voltage alternating current (HVAC) cable in the first phase of Dogger Bank Wind Farm.
The wire runs from the converter station to the Creyke Beck electricity substation.
Another significant landmark was reached as a full end-to-end test was completed at Dogger Bank A, which will allow offshore commissioning works to progress.
Jones Bros has already installed almost 77 miles of underground onshore high voltage direct current (HVDC) and 15 miles of HVAC cabling to help connect the first two phases of the project, Dogger Bank A and B, in the north of England to the national grid.
Due to its distance from the shore, it is the first wind farm in the UK to use HVDC technology comprising of just over 120km of ducting using open cut trench and horizontal directional drilling construction works.
As the turnkey power cable provider for Dogger Bank A and B, NKT will design, manufacture, joint and test the 320KV HVDC systems, which will have the capacity of 1200MW each when finalised.
Jones Bros project manager James Lockwood said: “It’s always fantastic to hit key milestones on any scheme, and to complete the HVAC cabling and the high voltage end-to-end test for Dogger Bank A is no different.
“Having been involved in works at the wind farm for three years, it is wonderful to see everything taking shape.
“We can now see the end of our activity on these project phases, with reinstatement works to be completed in September on completion of the high voltage end-to-end test on Dogger Bank B’s onshore cable route.”
Restoration activity to be finalised by Jones Bros includes the removal of haul roads, installation of new land drainage system, and the cultivating of fields, which are being handed back to owners.
