Wind farm project in Europe concludes survey for the continent's initial large-scale offshore wind development
The Green Volt floating offshore wind farm, one of the 13 projects selected by Crown Estate Scotland in 2023, is making significant progress. The project recently secured both onshore and offshore planning consents in 2024, paving the way for its development.
In a notable achievement, the Green Volt project was the only floating wind project awarded a Contract for Difference in the UK's Allocation Round 6 (AR6). This contract will provide financial support to the project, further boosting its prospects.
TGS, a leading provider of geoscience data for the energy industry, has completed an ultra-high-resolution 3D (UHR3D) seismic survey for the Green Volt floating offshore wind farm in Scotland. This survey, the largest of its kind to date, sets new benchmarks in channel count and streamer spread, providing critical insights for the project's geological analysis, site planning, and risk evaluation.
The survey integrated Multibeam Echo Sounder (MBES), Sub-bottom Profiler (SBP), Side Scan Sonar (SSS), and magnetometer data into a unified dataset. This comprehensive approach allows for a detailed understanding of the seabed and subsurface geological structures, aiding in the characterization of the site’s geology with unprecedented resolution.
The ultra-high resolution and extensive coverage of the survey enable more precise identification of optimal locations for floating turbine foundations. By detecting seabed features, obstacles, and sediment stability, this data directly influences the design and positioning of the wind farm infrastructure.
Accurate data from the large-scale survey significantly improves the assessment of geological and geohazard risks, contributing to safer and more cost-efficient project development. The enhanced risk evaluation informs mitigation strategies and reduces uncertainties before construction.
In another development, Worley, a global provider of professional project and asset services, has been contracted for the engineering design of the onshore substation for the Green Volt project. A team from Worley's Aberdeen office will lead the Front-End Engineering and Design (FEED) for the Green Volt onshore substation. The onshore substation engineering work is anticipated to commence and last for twelve months.
The Green Volt project is planned to feature 35 floating wind turbines and is expected to produce its first power in 2029. With the engineering phase for its onshore substation now underway, the Green Volt floating offshore wind farm continues to move forward, bringing Scotland one step closer to a more sustainable energy future.
