 Low-Turbidity Dredgehead Designs
Category:
Environmental Dredging
Pipeline/Discharge Systems
Description:
Jan de Nul has developed the low turbidity dredge head (LTDH) . The LTDH has been installed
on the cutter suction dredge "Dirk Martens", and is designed to:
1. Remove thin layers of silt with high accuracy.
2. Dredge material at in-situ density.
3. Work in shallow areas.
4. Minimize the mechanical disturbance to reduce turbidity generation and mobilization of
5. Extend the automation and monitoring of the dredging process.
The LDTH or sweephead has two inlets and works without additional mechanical movements. A
hydraulic valve in the head opens the inlet towards the dredging direction.
