Edinburgh will become a major centre supporting giant offshore wind construction projects in the North Sea under plans unveiled for the Port of Leith.

The plan aims to create Scotland’s largest renewable energy hub as the nation chases deployment of 11GW of fixed-bottom and floating projects in its waters by 2030, and follows warnings its ports may not be up to the task.

Owner Forth Ports will spend £40m ($57m) as a “pump priming” investment in a berth able to host “the world’s largest offshore wind vessels”, a 1,000 tonnes per square metre heavy lift capability and adjacent land for logistics and marshalling.
