Subsurface Insights for Wind
For over 40 years, TGS has led the way in subsurface imaging and insight. Today we apply our vast experience and the world's largest data library to enhance subsurface and cabling decisions for offshore wind.
Experts in the Subsurface
For over four decades, TGS has built a strong reputation in subsurface expertise. With the world’s largest subsurface data library, we are at the forefront of technologies such as ocean bottom node (OBN) and ultra-high resolution 3D (UHR3D) seismic acquisition. Our continued innovation supports more informed decision-making in the offshore wind sector, offering acquisition, imaging, and interpretation either as standalone services or a fully integrated solution.
We support key site characterization objectives, including turbine placement, foundation selection, and cable and pipeline planning, through high-resolution subsurface insight.
Superior Site Characterisation
TGS’s ultra-high resolution 3D (UHR3D) seismic acquisition and imaging technology delivers exceptional clarity of the shallow subsurface, supporting detailed site characterization. Seismic acquisition, imaging, and interpretation are available as a fully integrated package.
By incorporating Multibeam Echo Sounder (MBES), Side Scan Sonar (SSS), Sub-bottom Profiler (SBP), and Magnetometer (MAG) sensors, surveys provide a more complete geological picture to support site planning and risk mitigation.
High-resolution seismic data helps reduce reliance on extensive geotechnical sampling and supports the development of more accurate ground models, lowering cost and minimizing uncertainty.
Seismic Data Library
Seismic data offers a powerful view into subsurface structures, supporting better decisions around turbine placement, construction planning, and long-term maintenance. TGS delivers industry-leading seismic and well data, along with expert interpretation powered by advanced technologies. Our licensable subsurface data library is the largest in the world, covering all major offshore basins as well as key onshore regions.
Desktop Studies
TGS provides early-phase ground condition and geohazard evaluations for offshore wind farm development. We support wind farm front-end engineering design (FEED) studies and survey evaluation and design (SED) through the development of multi-client (non-exclusive) desktop studies.
Using combined experience in geophysics, geology, geotechnical engineering, and environmental geotechnics, these detailed desktop studies use relevant subsurface data. The focus is optimizing the efficiency and cost-effectiveness of ground model development for foundation and data survey designs.
