Wind Energy – Seagreen
Construction of Seagreen, Scotland’s largest fixed bottom offshore wind farm and the world’s deepest of its kind, has reached another critical milestone with the installation of the 4,800-tonne offshore platform topside off the Angus coast.
The topside forms the backbone of the offshore wind farm. At 40 metres long, 45 metres wide and 15 metres high, the heavyweight superstructure’s role is to collect and manage 1,075MW of power generated by the 114 Vestas wind turbines before transferring it ashore via around 60km of offshore subsea cabling.
Once onshore, the electricity continues to the new Tealing substation near Dundee via a further 19km of cabling for onward distribution to homes and businesses via the national electricity network.
The topside was lifted from heavy transport vessel Thialf onto the previously installed 6-legged jacket foundation. The completed structure sits in water depths of around 55m and will be one of the largest AC platforms in UK waters.
