  • Route surveys, combined with bottom mapping and ROV inspection, engineering, installation and documentation of pipes, wires and cables
  • Mapping and classification of seabed conditions
    • Streamlines bottom hardness identification and anchor selection
  • Efficient and accurate mapping in the planning phase, for example quay facilities, harbor surveying, dredging and fillings, magazine mapping for volume calculations
  • Detection of objects in the water column, for example chain, cables
  • Detection of objects on the seabed, for example car wrecks, boat wrecks, chains, cables
  • Bathymetric mapping / depth mapping
