Offshore geophysical survey

Refraction and reflection seismic are geophysical methods used to investigate the structure of the geological medium both onshore and offshore.

GT offers comprehensive geophysical services dedicated to environmental research for the needs of the OWF

• Bathymetry and hydrography
• Magnetometry
• Seismoacoustics
• Single-channel seismic
• Multi-channel UHR seismic
• ROV (remotely operated underwater vehicle)

UHRS – Ultra High Resolution Seismic – offered by GT provides a highly accurate image of the geological structures underlying the seabed.
