Damen DOP200 for Amsterdam Job

On the North-Eastern outskirts of Amsterdam a vital lock complex controls the water levels and salinity of the inland waters.

Recently, Paans Van Oord renovated the lock complex, which was a major challenge in the short time frame available.

The full job lasted only 4 weeks, and the crammed program included a wide range of renovation and repair jobs to the lock sill and lock head. In order to clean the lock bottom, the company used the DOP submersible dredge pump with a special suction head.

The DOP200 was mounted on the boom of a Liebherr R954C EW excavator, which had been placed on crane barge “Anna-Catharina”.

According to the company, only 3 days were required by the DOP200 and crew to clean the lock bottom – which has a surface of just over 1.000m². The sediment was pumped in a barge located alongside the crane barge, Damen said.
