Hydrographic Survey

The aim of the Hydrographic survey is the thorough study, description, and characterisation of seafloor mapping


Hydrographic surveying is one of the oldest forms of marine research. It is of increasing importance in all fields of maritime activity (navigation, marine construction, dredging, offshore rigs, oil exploration and related activities). During the past 20 years Hydrographic surveying has dramatically changed in equipment performances, acquisition and processing software, results presentation and sharing.

Hydroconsult closely follows these evolutions and constantly upgrades its personnel skills in order to master the latest technology to ensure reliable and accurate data.

Our specialists supervise, conduct or control  all your hydrographic works in various types of water  including rivers, lakes, seas and oceans. Hydroconsult performs hydrographic survey from the shallow waters in nearshore areas, to the deepest ocean waters.

According to your survey project, bathymetric data can be collected using single beam echosounder or most commonly through multibeam echosounder  which is linked to high accuracy GNSS, motion sensors and inertial integration. During a bathymetrical survey, the equipments are mounted on a survey vessel, ROV, AUV, RSV.


The high-resolution functionality of the Side Scan Sonar allows  to efficiently create a near-photographic image of the seabed. This technology  gives a precise representation of the seafloor. It is most suitable for detecting small targets, debris and other obstructions that may be hazardous to shipping, and by the oil & gas industry or green energies maritime installations.

Side Scan Sonar imagery is also commonly used by Hydroconsult team to conduct surveys in the field of marine archaeology, wreck search as well as dredging operations and environmental studies.
