Geotechnical Surveys

Seabed Sampling Experts

Briggs Marine can provide a range of geotechnical sampling from its survey vessels, multicats and larger vessels.

Grabs are deployed safely through the vessels hydraulic “A” frame and fitted deck winch. The lifting arrangements and deck space allow for efficient operations and high levels of safety.

Additional geotechnical tasks delivered from the survey vessels include gravity coring and other light geotechnical devices. Positional information is provided using the vessel’s on board navigation system.
