TGS Awarded Offshore Wind Site Characterization Contract

OSLO, Norway (29 January 2025) - TGS, a leading provider of energy data and
intelligence, is pleased to announce the award of an offshore wind site
characterization contract on the UK continental shelf for a repeat customer. The
contract has a total duration of approximately 60 days and is scheduled to
commence in Q1 2025.

The Ramform Vanguard will be used for this project and is equipped with Ultra-
high-resolution 3D (UHR-3D) streamers. The streamer technology samples the
seismic wavefield at a high spatial and temporal rate providing high-resolution
data of the shallow subsurface targets for wind farm development.

Kristian Johansen, CEO of TGS, commented, "We are very pleased to secure more
offshore wind site characterization contracts, extending our success in this
market during 2024. This project further highlights the integral role UHR-3D
acquisition has in providing our clients with better seismic data and helping
them make data-driven decisions for their wind farm developments."
