The Correll Group announced the completion of the first phase of a recent contract awarded by Prysmian Powerlink on EDF Renewables UK and ESB owned
Neart na Gaoithe (NnG) offshore wind farm.

The first and completed phase was for the pull-in of a 220kV HVAC export cable to each of two offshore substation platforms. The scope of work also consisted of the internal platform works on the south platform including; securing the subsea cable at the hang-off, stripping, routing & cleating the High Voltage (HV) cores to the switchgear, separating, installing and splicing the fibre optic cables. HV & OTDR testing was also performed following the completion of each export cable.

The second and final phase, scheduled for 2023, will involve the completion of the internal platforms works on the north platform.

Energy from the offshore substation will be transmitted through two 37km-long export cables making landfall at Thorntonloch Beach in East Lothian. From the landfall point, an onshore cable will run underground for a distance of 12.3km to a land grid connection substation, near the Crystal Rig onshore wind farm in the Lammermuir Hills.

Sam Dowey, Managing Director at Correll, commented; “It was extremely satisfying to complete this project and to be again working in close partnership with Prysmian Group, having collaborated on many previous projects”.

The 450 MW NnG wind farm is 15km off the coast of Fife and is owned by EDF Renewables and ESB. The offshore wind farm will be equipped with 54 Siemens Gamesa SG 8.0-167 DD turbines with a tip height of 208m. They will be mounted on foundations laid at a water depth of up to 55m.
Once fully operational, it is expected to generate electricity for around 375,000 homes, or all domestic properties in a city the size of Edinburgh, and to displace 400,000 tons of CO2 annually. LCCC awarded it a CfD in February 2015, with a strike price of £114.39/MWh. The first turbines are scheduled to be operational in time for the wind farm to begin generating power in 2023, with completion scheduled for 2024.
