DOP Submersible dredge pumps

DOP350 relocating sand for dyke construction

Project Summary

Location: Alter Koog, Nordstrand peninsula, Germany

Period: Q2, 2014-Q3, 2016

Challenge: The DOP as key in a supply chain of sand moving equipment

Solution: DOP350 with cutter unit

Contractor: Reinhold Meister Wasserbau GmbH

Mr Jaap Boor – DIESEKO BV

“The DOP350 is the first choice for the job as it easily pumps high mixture capacities over important distances, making it the most efficient way to tackle the job.”

A DOP350 pumps sand from a temporary pit to several spoil fields. From these spoil fields the sand is taken by dumper trucks to the exact location on the reinforced dyke.

The DOP as key in a supply chain of sand moving equipment

The German coastal protection dyke named “Alter Koog” is being reinforced over a distance of 2.5 kilometres. The height is being increased to 8.70 meters above MSL (mean sea level). As a rule of thumb, a one-meter dike elevation means widening a dike by 10 meters. This results in the supply of some 300,000 m3 of filling sand.

On this quay the DOP350 is set at work.

The sand is won at sea by a trailing suction hopper dredger. The split hopper not only wins but also transports the sand, dumping it directly in front of a temporary quay. On this quay the DOP350 is set at work.

The DOP350 is the first choice for the job

The DOP350 submersible dredge pump is relocating the dumped sand to several sedimentation areas. With its high capacity of 900 m3/h of solids over 100 m and more than 700 m3/h over 500 m, the submersible dredge pump efficiently mines and transported the sand over the required distances.

The DOP350 is mounted on an excavator and driven by an ICE 900 power pack.
