Gardline leads the field in geophysical marine surveying. Dependable and second to none in QHSE, Operational Excellence, 3D High and Ultra High Resolution Seismic and other innovative solutions, we stand out with our customer centric and result driven project approach.

To support our clients to make the best decisions on the design and development of offshore installations, Gardline provides vital and detailed information of the seabed and underlying sub strata. Operating the world’s largest fleet of permanently mobilised survey vessels, we have the knowledge and resources needed for any marine site survey. 

One of our core businesses and expertise is the provision of geophysical surveys to investigate whether the conditions on the seabed are suitable for the installation of offshore structures such as platforms and drilling rigs, pipelines, wind turbine foundations and cables. 

To date, Gardline has successfully completed more than 11,000 marine survey projects for oil and gas operators and offshore wind farm site developers.

What is our data used for?

Hydrography and geophysics are central to any site investigation, used to inform client’s downstream EIA and engineering requirements.

How is our data used?

Hydrographic surveys are focussed on obtaining high quality bathymetric data of the seabed. A geophysical survey typically involves gathering data to inform on ground conditions and identification of any man-made and naturally occurring hazards that may adversely impact the objective of the site investigation (geohazards). This includes: water depths, seabed topography, seabed and sub-seabed obstructions, seabed soils, shallow and deeper geology.
