TGS Completes Record-Breaking Seismic Survey for Green Volt Floating Offshore Wind Farm

TGS has recently wrapped up an ultra-high-resolution 3D (UHR3D) seismic survey for the Green Volt floating offshore wind farm in Scotland. The project, developed by a consortium of Flotation Energy and Vårgrønn, marks a significant milestone in offshore renewable energy development.

The survey conducted by TGS utilized Multibeam Echo Sounder (MBES), Sub-bottom Profiler (SBP), Side Scan Sonar (SSS), and magnetometer data to create a comprehensive dataset. This data will play a crucial role in geological analysis, site planning, and risk assessment for the Green Volt offshore wind farm.

Setting new industry benchmarks, the survey on the Ramform Vanguard featured a remarkable channel count and streamer spread, surpassing previous UHR3D surveys. TGS highlighted that the vessel towed more channels than ever before, matching the performance of 4D GeoStreamer technology.

The Green Volt floating offshore wind farm, with a capacity of 560 MW, was selected by Crown Estate Scotland in 2023 as part of a pioneering leasing round targeting offshore wind energy supply to oil and gas platforms. The project is set to comprise 35 floating wind turbines and aims to commence power generation in 2029.

In 2024, Green Volt secured planning consents for both onshore and offshore components, becoming the sole floating wind project to receive a Contract for Difference in the UK’s Allocation Round 6 (AR6). Worley recently clinched a Front-End Engineering and Design (FEED) contract for the onshore substation, with the Aberdeen office leading the engineering efforts over the next twelve months.
