DOP Submersible dredge pumps

DOP250 busy with environmental clean up in Antwerp harbour

PROJECT SUMMARY

Location: Antwerp, Belgium

Period : Ongoing from 2010

Product type : DOP250 with cutter unit

Contractor : SeReAnt

Two customised DOP submersible dredge pumps plus their ladders have been delivered to SeReAnt for the Antwerp harbour clean up project.

Two customised DOP submersible dredge pumps plus their ladders have been delivered to SeReAnt for the Antwerp harbour clean up project. This project is an enormous construction project including all phases required from removing in situ harbour sludge to final storage of dry filter blocks.

One phase is the storage of silt, which is to consolidate to its near in situ density. This storage is done in 4 wedge-shaped settling tanks of 120.000 m3 each. Over these storage tanks runs a fixed 173 m long 24 m high bay, to which 2 controllable trolleys are connected. Attached to each trolley is the Damen ladder with integrated DOP submersible dredge pump.

DOP250 with cutter unit in customized configuration.

The working angle of the DOP250s, which are identical and interchangeable, can be adjusted by means of a hydraulic cylinder. Depending on the amount of silt stored, it works at a maximum dredging depth of -6 m.

The ladder integrates the DOP pumps discharge piping, plus its hydraulic piping and signal cables. The compact design of the DOP was of vital importance in the intricate project set up.
