The Inch Cape offshore wind project reached a new development stage after completing the installation of 54 monopile foundations that will support a large portion of the turbines at the complex located in the North Sea off the coast of Scotland.
Since last December, the heavy-lift vessel Les Alizés, operated by Jan De Nul, has carried out the transport and installation of the monopiles from the port of Leith, Edinburgh, to the offshore site. Each trip allowed up to five structures to be mobilized for progressive placement on the seabed.
Offshore Monopiles Noted for Their Size and Capacity
According to project officials, the foundations used at Inch Cape are notable for their dimensions. The monopiles reach diameters of 11.5 meters, lengths of up to 102 meters, and weights close to 2,300 tons.
To execute the operations, Les Alizés used a crane with a 5,000-ton capacity and a lifting height of 160 meters. The maneuvers also incorporated specialized IQIP equipment for lifting and pile driving.
Likewise, the installation required advanced geotechnical studies due to the complex conditions of the seabed. The analyses were developed by Geowynd with technical support from Cathie to reduce risks during operations.
Environmental Measures During Offshore Construction
The execution of the works included various protection measures for marine mammals present in the area.
Implemented actions include acoustic deterrent devices, gradual start-up procedures during pile driving, and a continuous underwater noise monitoring program. These initiatives aim to minimize the impact of construction activities on the marine ecosystem.
Next Phases of the Inch Cape Project
In addition to the 54 monopiles and their corresponding transition pieces, the wind farm will incorporate 18 jacket foundations secured by 54 pin piles.
Once completed, Inch Cape will feature 72 Vestas 15 MW turbines, consolidating its position as one of the most significant offshore wind energy developments in the United Kingdom.
Currently, nearly 100 workers continue to carry out logistical activities at the port of Leith, where the remaining components for subsequent installation campaigns are being prepared with support from Global Energy Solutions.
Objective: Operation by 2027
Planned activities for the remainder of the year include the installation of transition pieces, jacket structures, outstanding sections of the second export cable, the first inter-array cables, and the project’s first turbines.
According to the established timeline, Inch Cape plans to produce its first energy by the end of 2026 and commence commercial operations during 2027.
The project is jointly owned by ESB and Red Rock Renewables, companies that are jointly driving this initiative aimed at expanding the UK’s renewable generation capacity.
