IMS Dredging GPS System

The IMS Dredging GPS System allows users to monitor and record digging operations for the IMS Versi-Dredge and IMS Depth Master dredging systems and satisfied USACE Silent Inspector requirements.  The survey data is displayed on the operator’s screen and re-mapped in real time, based on the depth and location of the IMS SolidsMaster Cutterhead system.  This allows the operator to maximize digging efficiency while providing a record of digging operations for their client(s).

The IMS GPS System tracks the following:

  • Dredge Position
  • Dredge Heading
  • Dredge Cutterhead Depth

The operator must upload an XYZ file or pre-dredging survey into the GPS laptop.  This will allow the system to do the following:

  • Provide a history of dredging operations
    • Shows “as surveyed”
    • Shows “as dredged”
  • Cut real time profiles at the digging tool position
  • Update the “As Dredged” surface based on the depth of the digging tool

Real time sections in the IMS GPS program can be:

  • Plan view
  • Sectional views
  • 3DTV Perspective view

The IMS Dredging GPS System is comprised of the following components:

  • Dredging GPS real time dredge monitoring software
  • Dual antenna DGPS for dredge positioning and heading
  • Pressure sensor to calculate depth
  • Notebook computer installed above right dash via mounting arm for data collection and display (removable for security purposes)
  • Tide Gauge for real time tide correction
  • A/D converter, 4-20mA/RS232
  • Computer 2-port serial card
  • Power inverter, 12vdc/120vac
  • Wires, terminals, misc. hardware
  • Installation of equipment at IMS factory
  • Field start up and training services
