Construction of the UK’s largest offshore wind tower factory is set to start imminently at Nigg in Scotland, once a key fabrication yard serving the North Sea oil and gas industry.

Transformation of the site is being financed by an initial £110 million ($145 million) investment from a syndicate comprising SSE Renewables, Mainstream Renewable Power and the Sequoia Economic Infrastructure Income Fund.

At the heart of the site will be a 450-metre long, 38,000 square metre fabrication facility that, once in production, will be able to annually roll out some 135 large-diameter towers using a robot-run electro-beam welding assembly line.
