Photo Update: Damen DOP350 Working in Herten

Image source: Damen

De Rosslag marina dredging project in Herten, conducted by the contractor Martens & Van Oord, is progressing according to schedule.

The capacity of the existing marina, located on the river Maas, is being doubled by using Damen’s DOP350. The submersible dredge pump wins the local mixture of sand, gravel and clay to a depth of approx. 6.5m.

The medium sand won on the spot is partially reused on the spot to build quays, a parking area etc; the clay is reused creating the quay walls. The remaining sand and gravel is transported by barges to the contractor’s classification plant, Damen said in its latest project update.

The DOP350 is connected to a pontoon-based excavator. On the same pontoon a diesel hydraulic power pack is placed for providing the hydraulic power to the DOP350.

Another pack ensures the jetwater to the sand mining head, thus loosening the soil and boosting production.
