It will supply enough low-carbon electricity for around 375,000 homes and will offset over 400,000 metric tons of CO2 emissions each year. NnG, jointly owned by EDF Renewables and ESB, will have a capacity of c.450MW. The first turbines will be operational in mid-2023, with the completion of the entire wind farm scheduled for 2024. Once installed, the power generated by the offshore wind farm’s turbines will be exported via NnG’s two offshore substations to its onshore substation where the energy will access the National Grid’s entry point at Crystal Rig in the Lammermuir Hills, East Lothian. The innovative ‘rock socket’ seabed supports for the jackets were prepared last year by the Saipem 7000 and Saipem 3000 construction vessels in a water depth of approximately 50 meters, to anchor the offshore substation to the seabed. Both foundation jackets were designed in London by Saipem’s in-house design team and constructed at Saipem’s fabrication yard on Karimun Island, Indonesia. Saipem, NNGOWL’s Foundations EPCI Contractor, using the largest offshore wind installation vessel in the world, Heerema’s Sleipnir, placed the 1100 metric ton topside onto one of the two foundation jackets. This milestone means NnG can be fully connected to the National Grid ahead of the project’s 54 wind turbines being installed in 2023. Neart na Gaoithe (NnG) offshore wind farm, under construction 15km off the coast of Fife, has achieved a major milestone as Heerema Marine Contractors installs the first of its two offshore substations at the site of the project.
