  • inside harbors to check minimum draft, for dredging estimation or as preliminary survey;
  • outside the port to monitor erosion phenomena, sensitive habitats or to observe the effect of a beach nourishment;
  • in open water as preliminary survey for marine constructions (wind farms, oil and gas facilities and pipe and cable laying).

Features

Fast and accurate methodologies can provide a seabed image of wide areas with the full coverage.

Technical specifications

•Dual frequencies (100-500kHz) side scan sonar

• Acoustic backscattering from high frequency multibeam system

•  Real time mosaicing

• Fast data playback for quality asessment
