All 54 monopile foundations have been installed at the 1.1 GW Inch Cape offshore wind farm in Scotland, marking a major step in the project’s offshore construction program.
The project is jointly owned by ESB and Red Rock Renewables. Installation was carried out by Jan De Nul’s heavy-lift vessel Les Alizés, which transported the foundations from the Port of Leith in Edinburgh after the campaign began in December 2025.
The vessel was made available to Inch Cape under an arrangement linked to its long-term charter with RWE, which leased the ship to the project between its own construction work.
The monopiles were manufactured by CWHI and Dajin Heavy Industry. According to the joint venture, the foundations rank among the largest installed in the offshore wind sector, with diameters of 11.5 m, lengths of up to 102 m and weights of about 2,300 tonnes.
The wind farm will use 72 Vestas V236-15.0 MW turbines. These will be supported by 54 monopile foundations and 18 jacket foundations, with the jackets secured by 54 pin piles.
Further offshore work is scheduled to continue this year. Planned activities include transition piece installation, jacket foundation installation, completion of remaining sections of the second export cable, inter-array cable work and installation of the first turbines.
The 1.1 GW Inch Cape offshore wind farm is expected to generate first power in late 2026, with full commercial operation planned for 2027.
