Decades of dredging equipment

A long history in dredge building

The Damen Group dredger manufacturer

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.

Based in the making of the Dutch polders

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 full dredging package

Damen Dredging Equipment provides, as it has done for the past 80 years, high-end innovative solutions to the challenges dredging contractors face. Modularly built dredgers and the variety of dredging components available all withstand the tough conditions faced by the dredging industry.

Built for the future

Scores of dredgers have left our yard over the years. The smaller stationary dredgers were designed to clean ponds, lakes and irrigation channels. Mid-size dredgers haven been used to clean harbours, ports and navigation channels. Larger dredgers haven been used in mining pits and capital dredging projects creating new harbour quays, fairways etc. All dredgers are designed by our in-house dredging specialists.

Best possible solution

The Damen Dredging yard continuous to be the focus point of dredging products within the Damen Group. This ensures that each newly designed dredger is practical, efficient and that it incorporates the latest developments. Through smart customisation the best possible solution is proposed to the dredging contractor – engaging over 80 years of history and knowledge as a firm base.
