Principle of electronic remote monitoring

Electronic remote monitoring is a state of the art method for continuously analyzing and documenting the operation and performance of dredging systems from a remote location. Electronically measured mechanical, geotechnical and nautical dredge parameters describe in detail the operating characteristics of any sailing or stationary dredging equipment. Thus all information needed for monitoring and control of dredge operations is obtained from the evaluation of measured data. The typical procedure includes the data logging on board of the ship (with HMT owned equipment), the transmission of measured data to any remote location and the processing of data for monitoring, analysing and control purposes. Supervising personnel on board of the dredge is not necessary.

Scope of remote monitoring


  • Remote electronic supervision of hopper dredge operation

Monitoring, calculation and documentation of:

  • Volumes and masses     
  • Transport distances         
  • Operational periods e.g. sailing, dredging, discharging/dumping
  • Position and depth control of all dredging elements    
  • Automatic recognition and control of dredging and dumping sites    
  • Automatic recognition of administrative domain
