Our compact 4” Dredge System is equipped with an incorporated back flush control and can be ROV-mounted or utilised by a diver. The hydraulically-driven dredge allows for excavation of seabed sand, gravel, clay and rocks up to 76mm (3”) in diameter. Designed to run effectively on low hydraulic flows, the dredge weighs only 47kg in water.

The attached frame can be easily installed onto a ROV if required, with a comprehensive spares package available. When the dredge is utilised by a diver, a hydraulic power unit and umbilical reel is required.
