Offshore Wind

Data to support your investment decisions in wind energy infrastructure

Data first and data last

Exploding quantities of data in the offshore wind industry have the potential to fuel a new era of injecting valuable data and intelligence into decision-making processes. TGS can leverage long-term experience in Data Analytics, Imaging capabilities, and large amounts of geoscience data to enlighten your offshore wind development and investment decisions. Our current energy data library now includes exclusive regional wind energy datasets offshore East Coast US and the entirety of offshore Scotland. We also possess detailed bathymetry information, geochemistry analysis, and shallow subsurface imaging in current and future wind farm development areas.

Numerical Weather Prediction Models (NWP)

TGS, in collaboration with Vaisala, a global leader in weather, environmental, and industrial measurements, has developed unique regional wind energy datasets offshore East Coast US and the entirety of offshore Scotland.

Our comprehensive numerical weather prediction (NWP) models are designed to reconstruct meteorological conditions from the last 10 years at a spatial resolution of 1km with an hourly temporal resolution, providing operators interested in offshore wind lease sales with a unique, immediately available data resource that can evaluate wind conditions over each block and on a regional basis. This modeled data can be accessed and visualized via a fast and convenient on-demand digital platform.

SubSurface Data


This technique measures the strength of the returned sonar ping and helps to determine soft, medium, or hard seafloor. Subsea geologic hazards can be identified on backscatter data.


Detailed seafloor characteristics and the depth of water affects the type of turbine technology used to develop a given offshore farm


Multielement geochemistry of the seafloor sediments provides important markers for site assessment
