PROJECT SUMMARY

Period : Q4, 2015-Q2,2016

Product type : DOP250 with customised drag head

The drag head bottom pressure can be altered using the hydraulic cylinder.

For removing sand and larger debris along a newly built quay wall, a DOP Submersible Dredge Pump 250 has been fitted out with a customised drag head. The head is fitted out with a pressure balanced hydraulic cylinder to enable the contractor to vary the pressure on the bottom.

The drag head, fitted out with a grid to prevent large stones or debris to enter the process, is directly connected to the dredge pump through a rubber hose.

A customised large mounting flange and standard hydraulic snap tie quick couplings

The DOP250 will be attached to existing equipment. With the DOP the complete dredging package was delivered including flexible rubber discharge hoses with floats and a set of hydraulic hoses.

A suction hose connects the special drag head to the Damen Submersible DOP Dredge Pump 250
