Surveys in Shallow Water

Innomar's shallow water SBP models ("Innomar smart", "Innomar compact", "Innomar light", "Innomar standard") are specified for water depths starting at half a meter and going up to 500 metres. Thus this eqipment can be used for many applications in- and offshore like

  • surveys in rivers and harbours
  • surveys in coastal areas
  • sediment investigation vor dredging projects
  • pipeline and cable route surveys
  • location and monitoring of buried pipelines and cables
  • underwater archaeology

 

Shallow Water Data Examples

The following echo plots show some data examples obtained in shallow waters at water depths between about 25 and 350 metres.
