Efficient Dredging is more than just perfect instruments and automated equipment. It also means dredging in the right place and avoiding under- and over-dredging, regardless of the type of dredger. Careful planning, online verification and confirmation of the quality of the work are the keywords.


IHC Systems has developed the essential tools for this purpose, providing customers with even more effective ways to:

  • determine exactly where to dredge and to forecast material quantities
  • present the dredger in a digital terrain model (DTM) and bathymetric charts
  • update chart data online during dredging
  • immediately deliver proof of performance and a basis for payment upon completion
  • hook up a wide range of position information apparatus easily
  • install 3D terrain and dredger presentation add-ins.

With input from gyrocompasses, echo sounders, tidal transmitters, DGPS and other positioning systems, dredge track presentation system (DTPS) packages are suitable for operations on board survey vessels and dredgers to tolerances, defined on the basis of both cost and job requirements, that can be to within centimetres.


The package also includes fully equipped survey vessels, multi-channel telemetry systems, sonar/multi-beam sonar, sub-bottom profilers and so on. As well as simulation and training for crews and operational staff. The packages also allow operators to do their own training on board during downtime.
