Maintenance dredging of a navigation channel and silt-trap management.
The challenge
Restore design depth to a silted navigation channel while managing turbidity and disposal to environmental limits.
Our approach
We dredged to design profile with turbidity monitoring and silt curtains, and managed disposal of arisings to the agreed regime.
The outcome
Design depth restored across the channel with turbidity held within limits throughout.
