en.Wedoany.com Reported - TGS and Geo are set to conduct survey work for a wind farm in the Irish Sea. The two companies have secured a site investigation contract for the Awel y Môr project, located 10 kilometers off the north coast of Wales. Power giant RWE secured a Contract for Difference for this 78-square-kilometer wind farm in January, which can accommodate up to 50 turbines.

The upcoming site investigation will support the optimization of the array design and its export cable route, which leads to a landfall point between Rhyl and Prestatyn. TGS will be responsible for geophysical surveys, using high-resolution imaging to map the seabed geology in detail, including identifying variations in rock layer depth, large boulders, and other features that may impact construction.

Geo will conduct geotechnical investigations using Cone Penetration Testing (CPT) and vibrocore sampling techniques to study the geological properties of the seabed. This work will build on previous borehole surveys and research from Bangor University. The Danish company plans to deploy two vessels to operate in different areas of the sea. The newly built heavy CPT rig GeoScope II will be used in the wind farm array area, while the combined CPT and vibrocore rig The GeoCeptor will carry out tasks along the offshore export cable route.

Jo Pickard, Senior Consents Manager at Awel y Môr, stated that these additional survey data will enable the team to optimize the design and adjust offshore construction methods, which are currently planned to begin in 2029. Onshore construction is scheduled to start in 2027, with cable route work commencing the following year. The wind farm is expected to be completed in 2031, with turbines reaching heights of up to 332 meters.

Awel y Môr is owned 60% by RWE Renewables, 30% by Stadtwerke München, and 10% by Siemens Financial Services. Dutch data specialist Fugro began initial geotechnical site surveys for the project in 2022, which received development consent and a marine license in 2023.
