In order to optimize the service, get more flexibility in organizing projects and ensure the quality of our services, G-tec has developed a polyvalent and diversified fleet to suit survey needs and meet customers' particular demands. G-tec owns and can make available a large variety of vessels for all kind of marine projects to suite the clients' needs.

G-tec has vessels to explore both inland waterways and marine environments to meet various customers' demands.

Our vessels are designed to meet the field constraints and the survey's necessities. For example, part of our vessels have limited draft, which makes them suitable for waterway campaigns and to pass through very shallow areas.

Many of our vessels are road trailerable and can carry out surveys far from their original location.

They can be equipped with a wide range of geophysical and geotechnical equipment to support a large panel of coastal, offshore and estuarian, inland waterways, lakes and dams survey services . Our vessels can be used to meet several objectives such as:

  • studying the topography of river-or seabed and the sedimentation and erosion processes
  • monitoring of obstacles, banks and other object that can hinder navigation
  • determining the precise bathymetry to calculate quantities of soil material to be dredged
  • conducting a site investigation prior to dredging or construction works, installation of cable lines
  • inspection of underwater structures such as dams or locks
