Dredging presents unique working conditions and safety concerns.

Trimble HYDROpro™ offers the ideal solution for improving efficiency by allowing the operator to “see” what’s going on beneath the machine or vessel. Material placement and dredging can be done much faster and with better accuracy than ever before..

The HYDROpro family of software offers specialized tools to allow the operator to “see” under water and dredge or fill to a 3D design by tracking the dredge head over a design shape.

HYDROpro and Trimble marine construction GPS sensors such as the Trimble SPS855 GNSS Modular Receiver and SPS555H Heading Add-on can be installed on several types of waterway dredging machines, including:

  • Clamshell buckets
  • Dredging excavators
  • Pile drivers
  • Wick drain rigs

It offers specialized tools for:

  • Precise placement of structures such as breakwaters, bridges, caissons, piles, marina piers and coastal defenses
  • Preparing underwater gravel beds for caissons and other structures
  • Positioning dredge vessels, barges, tugs and other vessels
  • Hydrographic surveys for channel maintenance, dredging progress, environmental surveys, and bed erosion
