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 four decades, TGS has held a strong reputation in subsurface expertise. We hold the world's largest subsurface data library and lead the way in cutting-edge ocean bottom node (OBN) seismic acquisition technology. We continue to innovate, developing new opportunities for TGS to enhance decision-making in the offshore wind industry through subsurface insight. Let us help you site turbines, choose foundation type, and manage cabling/pipelines through better subsurface images and unique desktop studies.

Seismic Data for Wind

Seismic Data

Seismic data gives a powerful and unique insight into the structure of the subsurface, vastly enhancing crucial decisions concerning turbine siting, construction, and maintenance. TGS provides industry-leading seismic data, well data, and interpretation of subsurface images using an innovative mix of technologies and unmatched expertise. Our library of licensable subsurface data is the largest in the world, covering all major offshore basins in addition to key onshore locations.

Desktop Studies

TGS provides early-phase ground condition and geohazard evaluations for offshore wind farm development in cooperation with SAND Geophysics and Norwegian Geotechnical Institute (NGI). 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.

Seismic Acquisition (UHR)

Our ultra-high resolution (UHR) 3D seismic survey acquisition and imaging technology provides the ultimate clarity of the shallow subsurface.

UHR uses a wide tow configuration combined with ultra-high frequency sparker sources, enabling enhanced resolution of the subsurface and true 3D imagery. Deeper tow enables better weather tolerance, signal-to-noise, active positioning of the spread, and system robustness.

Reduce costs related to geotechnical measurements and de-risk your ground model with ultra-high resolution seismic data.
