Trailing suction hopper dredgers

The Efficient Dredging concept on trailing suction hopper dredgers optimises:

  • the suction process during trailing
  • the settling process in the hopper
  • the accuracy of the location to be dredged
  • the dredge cycle time in relation to sailing time
  • the pumping process during pumping ashore or rainbowing
  • the utilisation and distribution of available power
  • the relations between these processes
  • crew training with IHC Systems simulators.

A range of products serves to achieve these goals. Usually they are embedded in completely integrated systems. However, dedicated monitoring systems and sensors  for almost any parameter are also available. It all focuses on optimum execution of dredging operations.

Control systems at the basic level provide manual or semi-automatic control for the hydraulically or electrically operated equipment such as sluice valves, bottom doors, winches and so on. More intricate versions also include process automation features.

The control and monitoring systems usually are shaped into fully integrated presentation, control and automation systems. These serve the total dredging and sailing process, including navigation, engine room monitoring, automation, and power management, one man-operated bridges and class-approved DP/DT systems.
