Construction of the Seagreen offshore wind farm has reached another milestone with the installation of a jacket in preparation for the project’s offshore substation topside which is due to be installed in early 2022. Engineered, constructed and installed by Petrofac and weighing 5,100 tonnes, the six-legged jacket is now fixed to the seabed, at a water depth of around 55m.
The jacket has a seabed footprint of 43m x 43m and has built in tubing designed to guide the incoming 15 inter-array cables bringing the electricity generated by the turbines to the substation. In addition, the jacket also has tubing to guide the outgoing three export cables from the offshore substation to the seabed. When completed in late 2022/early 2023, Seagreen will consist of 114 Vestas V164-10.0 MW turbines. Situated around 27km off the Angus coast, the £3bn wind farm is a joint venture between SSE Renewables (49%) and TotalEnergies (51%).
