Precision dredging

In high winds an amphibious excavator has done a precision dredging job near a Dutch dyke. The project aim was to remove a limited volume of silt – some 4.000 m³. The silt was to be removed to create a more stable basis for dyke reinforcement; the removed volume was to be replaced by sand in a second stage of the project.

The DOP200 dredge pump was connected to the boom of a “Waterking”, an amphibious excavator. The Waterking was fitted out with a power pack at its back , suppling hydraulic power for both the dredge pump and its cutter unit. To ensure precision dredging, the excavator was provided with a GPS system, plus the standard DOP dredge pump monitoring instrumentation.

The dredge pumped discharged using a partially floating pipe line of in total 150 m length. After removal of the silt layer, the dyke was reinforced using sand.
