NSEC members, together with the UK, currently have a combined installed capacity of about 33 GW. This means that some 87 GW of offshore wind is planned to be installed over the next seven years. However, this amount of new capacity is unlikely to be realised without additional dedicated port infrastructure.

While the offshore wind projects that will be built in the next few years have often already secured port capacity, installing this massive offshore wind capacity by 2030 and beyond that point comes with a much higher demand for specialised ports. According to the study, the peak in offshore wind energy deployment is anticipated between 2029 and 2031.
