Desilting of Enclosed Harbours, Marinas, and Boat Basins

KCC provides desilting services for enclosed harbours, marinas, typhoon shelters, and boat basins where silt accumulation has reduced navigable depth or degraded water quality. Unlike open-water dredging, desilting in enclosed basins requires careful management of silt disturbance to avoid re-suspension and turbidity impacts on adjacent vessels and structures.

KCC deploys silt curtains to contain the working area, uses low-disturbance suction dredging or diver-operated vacuum systems to remove silt with minimal re-suspension, and monitors turbidity continuously during works. Removed silt is pumped to shore-based settlement tanks or loaded into sealed barge containers for disposal at a licensed facility in accordance with CEDD and EPD requirements.

Compliance: Works are conducted in accordance with CEDD dredging guidelines, EPD Technical Memorandum on Dredging, and IMCA D 045. Turbidity monitoring follows the Environmental Monitoring and Audit (EM&A) requirements of the project environmental permit.
