Foundation installation completed at the 1.4 GW East Anglia Three offshore wind farm in the UK.
The GBP 4 billion (around EUR 4.7 billion) project, owned by ScottishPower Renewables and Masdar, announced on 17 August the completion of installation for all 95 monopiles and transition pieces, with wind turbines currently being installed.
Monopiles for the 95-turbine offshore wind farm were produced by Haizea Wind Group and Navantia-Windar consortium. Windar also supplied the transition pieces.
Seaway7, using its vessel Seaway Ventus, performed the offshore installation.
Developers stated the monopiles are the largest deployed from a jack-up vessel in Europe, weighing 1,200-1,800 tonnes, standing 67-84 metres tall, with diameters up to 10.6 metres. Transition pieces are 20 metres tall, 8 metres in diameter, and weigh over 400 tonnes.
“With the foundations now in place, Seaway7 continues inter-array cable installation, bringing East Anglia THREE closer to delivering clean, reliable power to over one million UK homes,” said Lloyd Duthie, Seaway7 CEO.
Wind turbine installation began in April and is expected to wrap up this year. The wind farm is set to be fully operational by the end of 2026.
The 1.4 GW wind farm will feature 95 Siemens Gamesa 14+ MW turbines, the first in the UK to include 115-metre blades, according to developers.
ScottishPower Renewables and Masdar highlighted an investment of approximately GBP 2 billion (around EUR 2.3 billion) in the UK supply chain, covering foundation design by Wood Thilsted, turbine blade manufacturing at Siemens Gamesa’s Hull factory, vessel charters from Norfolk-based NR Marine Services and OEG, and support from metocean and seabed consultants Partrac.
East Anglia Three supports 2,300 jobs during construction and will create nearly 100 long-term roles in East England, the project owners reported.
