Dredging
Pumping return water for the construction of a new port quay
Support for dredging operations
A trailing suction hopper dredger that powerfully sprays a mixture of sand and water over a long row of sheet piles. Impressive to see. Here, they are literally creating new land for a new port.
But where should all that water go? That's where Van Heck comes into play.
Pumping return water
The sand from the mixture settles within the sheet piles and forms the basis for the new port quay. The water remains behind and the water level rises.
Flowing back to the sea is not possible. That's why we have a temporary pumping station for the return water installed. It pumps the water back to the sea in a controlled manner, at the same pace as the trailing suction hopper dredger supplies the mixture.
The pumping station is located at a distance from the rainbow point. This gives the sand time to settle and primarily water is returned.
Sand remains. Water returns to the sea.
No room for standstill
The trailing suction hopper dredgers continuously come and go. Therefore, the return water installation must keep running.
A malfunction not only means that the pump stops, but it can delay the entire dredging operation. Reliability is not an extra here, but a requirement.
With a suitable pumping station and the right capacity, Van Heck ensures that the return water is discharged and the dredging work can continue.
