GB£30m infrastructure boost for Nigg

The GB£30m port construction project issued to McLaughlin & Harvey, will deliver a new 16,000m² heavy-duty quay with additional roll-on/roll-off (Ro-Ro) capability, enhancing the port’s ability to support offshore wind and wider energy industry operations.

“We’re pleased to be returning to the Port of Nigg, enhancing port capacity and operational capability by creating a new quay for the energy sector,” said Seamus Devlin, managing director at McLaughlin & Harvey.

“This project draws on our experience of delivering complex marine projects in port infrastructure across the UK and Ireland.”

Supply chain investment

Construction preparations are now underway on site, with the development supported by a GB£10 million grant from Highlands and Islands Enterprise as part of the Scottish Government’s offshore wind supply chain investment strategy.

McLaughlin & Harvey previously delivered major marine civils works at Port of Nigg between 2014 and 2015, including reconstruction of the South Quay and installation of a 370m combi-pile quay wall.

The new quay will act as a dedicated load-out and export facility for high-voltage cables manufactured at the adjacent Sumitomo Electric HVDC cable facility, strengthening the port’s role in offshore wind deployment.

“We’re pleased to be working again with McLaughlin & Harvey, who know this site well and understand what it takes to successfully deliver projects here to the high quality and safety standards we demand,” said Rory Gunn, facilities director at Maraen Port of Nigg.

”Their work on the South Quay transformed the capabilities at the Port of Nigg and enabled us to attract large Energy sector project which could previously not be accommodated at our site.”

Maraen Port of Nigg has already supported deployment of more than 4GW of offshore wind capacity and said the latest infrastructure investment would reinforce its position as a strategic UK energy port.

In July 2025, Global Energy Group sold three of its key subsidiaries – including the strategically vital Port of Nigg – to its long-term partner Mitsui & Co. Europe and Mitsui O.S.K. Lines (MOL).

Mitsui, a stakeholder in GEG since 2012, holds 51% of the acquired businesses, with MOL owning the remaining 49%.
