Damen DOP Submersible Dredge Pump 200 running on Hitachi crane hydraulics

At Kalba various breakwaters have been reinforced using a DOP200 attached to a Hitachi crane. The sand for the job was mined at sea, and pumped over a max 500 m distance to the jobsite. When the breakwaters were ready, more sand was pumped for replenishing local beaches.

The DOP200 requires 300 litres of hydraulic oil per minute at 250 bar, which was supplied by the Hitachi crane type Hit1200SLR. The DOP200 is connected to the boom by a standard excavators’ quick coupling.
