Norwegian seismic firm TGS has started a geophysical survey for the pioneering Green Volt floating offshore wind farm offshore Scotland.

Mobilization initiated in Aberdeen last week and the work is scheduled throughout June will include an ultra-high resolution 3D (UHR3D) seismic survey used to deliver detailed subsurface data for the floating windfarm’s site characterization.

Utilizing integrated Multibeam Echo Sounder, Side Scan Sonar, Sub-bottom Profiler and Magnetometer sensors, the advanced survey will enhance geological understanding and provide critical insights for the project’s site planning and risk assessments.

UHR3D data will provide detailed understanding of the subsurface conditions, revealing potential risks and challenges that are not always accurately captured through traditional 2D data interpolation.

The enhanced data collection will help the Green Volt project team identify geological hazards and structural complexities, contributing to improved site assessment and risk mitigation strategies. This, in turn, will form a reliable foundation for the project’s ongoing planning and execution. By leveraging the latest acquisition configurations, TGS will enhance efficiency and improve target resolutions to meet the highest industry standards.

The Green Volt project is a joint venture between leading offshore wind developers Flotation Energy and Vårgrønn. As Europe’s first commercial-scale floating windfarm at 560 MW, the project is a catalyst for developing a highly specialized U.K. floating wind supply chain.

"This represents a key milestone for TGS to utilize our expertise, technology and resources to support the development of the first commercial floating offshore wind farm, Green Volt.

“This simultaneous acquisition of all sensors and the application of our cutting-edge processing techniques is reinforcing our commitment to delivering industry-leader data solutions. UHR3D will be a key aspect to developing floating wind farms,” said Will Ashby, TGS EVP New Energy Solutions.

“Green Volt is pleased to be working alongside TGS on these important geophysical site surveys, which will not only advance our project but will also further develop our understanding of how the UKCS subsea offshore landscape can support deeper, larger windfarms as we continue to develop our industry.

“Accurate data is vital component in our learning and will help strengthen the UK’s floating wind supply chain. This contract supports local jobs and innovation, helping to build a world-leading offshore wind sector right here in the UK,” added Matt Green, Project Director for Green Volt.
