KEEPING THE NETHERLANDS ACCESSIBLE AND SAFE

Sand and silt are constantly settling in waterways and ports. Dredging is necessary to keep them accessible and safe for ships. And to ensure that the water can flow properly to prevent flooding. Replenishing is supplementing sand in places where it is needed. For example, on the beach or in the dunes to protect the Netherlands from the sea.

Dredging Specialist
Dredging and beach replenishment are among our areas of expertise. We carry out projects in the Netherlands and other countries within and outside Europe. Among others, we are active in France, the United Kingdom, Ireland, Poland and Germany. Both on inland waters and at sea.

Wide diversity of equipment
The various dredging activities each require a unique approach. The environment and space for execution strongly determine our working method. Thanks to the great diversity of our own equipment, we are able to carry out virtually any type of dredging work. Also in (smaller) ports and shallow channels. Our fleet includes hopper and cutter dredgers, but also crane ships, workboats and hydraulic cranes on pontoons. From our many years of experience, we know exactly which equipment is best suited to tackle a dredging project in the right way.

Dredging in inland waters
In addition to dredging at sea with our hoppers, we carry out a large part of our dredging activities on rivers and canals. The list of European waterways where we are currently dredging or have dredged is endless. We keep them at depth by dredging all year round. We take care of the entire process, such as conducting water bottom surveys and soundings. For this purpose, we have our own survey department at Van den Herik.

 

Did you know.

Our seagoing hopper dredgers the Charlock and the Christophorus are ideally suited for dredging and replenishment work close to the coast due to their limited draft and maneuverability.

Dredging abroad

For example, our expertise in dredging comes into its own in France. Together with our French subsidiary Eco Systèmes de Dragage, we keep several seaports in Normandy at depth.

These include the ports of: Dieppe, Ouistreham, Fécamp, Deauville-Trouville, Port-en-Bessin-Huppain, Grandcamp-Maisy and Le Tréport.

We carry out the work using a hopper dredger and a crane pontoon. These ports have many port activities that must not be disturbed. There is also a large tidal range: an average of five to six meters. The work therefore requires tight logistical planning.

Large-scale infrastructure projects

Naast onderhoud voeren we projectmatige baggerwerkzaamheden uit. Een recent voorbeeld zijn onze werkzaamheden binnen de combinatie Roggebot. Die is verantwoordelijk voor de herinrichting van het gebied rondom de N307 Roggebot bij Kampen.

In dit project hebben we bij de realisatie van een nieuwe brug en sluis de baggerwerkzaamheden uitgevoerd. We hebben daarbij meerdere van onze kraanschepen en baggerpontons ingezet.

Land sprawl

Suppleties hebben we onder andere uitgevoerd aan de Zeeuwse kust bij Dishoek, Zoutelande en Julianadorp. In opdracht van Rijkswaterstaat heeft een van onze hopperzuigers daar in totaal drie miljoen kuub zand opgespoten.

Zowel voor de kust en in de aanwezige geul – vooroeversuppletie – als op de stranden zelf met behulp van persleidingen – strandsuppletie. Zo hebben we de kust versterkt en blijft ons land beschermd tegen de zee.
