Doing a test run on quay

The carousel of 4 barges are continuously filled by a clamshell dredger. The barges are emptied using the DOP350 submersible dredge pump fitted out with a flat bottom head, which has jetwater assistance.

The DOP350 pumps the soil to a disposal site, some 200 m from the quay. The DOP350 is attached to an excavator boom. It is powered by a separate diesel-hydraulic power pack.

The sale was concluded after advice given by PVE-USA.
