A long history in dredge building
All dredgers, great and small
Damen Dredging once started modestly. It was established in the late 1930s as De Groot Nijkerk, and started working as a dredging contractor in the construction of the IJsselmeer polders. Gradually the focus shifted from contracting jobs to repairs of dredgers, both the company’s own dredgers and those from fellow contractors. The next logical step was new building. Many dredgers have been built since.
A long history in dredging
De Groot Nijkerk was acquired by the Damen Shipyards Group in 1988. It was a perfect match and both companies combined their specific knowledge of the dredging market. For years De Groot Nijkerk continued to market its stationary dredgers and trailing suction pipe systems under its own name. Eventually, in 2004, further integration within the group resulted in operations under the name Damen Dredging Equipment.

The trick is that the dock will remain in place during the dredging activities.
Damen dredging equipment launches new DOP Dredger series
Damen Dredging Equipment has launched a new DOP Dredger Series following the success of the DOP submersible dredge pump, which has proved its versatility across the globe. Damen has built more than 20 DOP dredgers on a one-off basis and at least 380 DOP pumps. The DOP submersible dredge pump has been such a great success over the last 25 years because of its simple concept, which is based on a well-proven dredge pump, directly driven by a hydraulic or electric motor, assembled in a rigid housing with the ability to attach all kinds of specialised suction devices, such as mining heads or cutter units. Moreover, the DOP can easily be connected to excavators, cranes, etc.
Damen DOP Dredger cleans up a reservoir
Modular dredger shipped to the Andes Reservoirs are notoriously tricky to maintain: from the surrounding area plenty of sand and silt is brought in by the river and the material deposits at the dam. As reservoirs are usually rather deep, dredging can be quite a challenge. For the Tablachaca dam in Peru another challenge was added; the location high up in the Andes required a modular dredger due to transport restrictions. The DOP Dredger proved to be the perfect solution.
