Dredging Knowledge

For centuries, mankind has used rivers and the sea as a transport route. So it is hardly surprising that the earliest Dredging. developed cultures were river dwellers who built canals to provide a water supply and a shipping route. As ships increased in size, making rivers and canals navigable required major feats of engineering. Barrages, locks and complex canal irrigation systems were developed. The continuing economic importance of shipping, waterways and ports, coupled with the sensitive physical and ecological environment of our rivers and coasts, means that carefully developed concepts and responsible management are still required today.

Waterways have to be maintained to keep shipping safe at all times, since the constant process of erosion and Floating Line with Floating Hoses. sedimentation (build-up of gravel and particulates) leads to bottom changes. Hence, one of the core tasks of the marine safety authorities, economic development agencies and maritime businesses (port operators, logistics companies and shipowners) is to maintain and restore adequate depth by means of dredging. Maintenance dredging is carried out not only in port areas but also in coastal shipping lanes and inland waterways. The lion's share of dredging work takes place in river deltas.

Why dredge?

In the context of waterways, excavation is normally taken to mean dredging, since the spoil is extracted underwater. Dredging serves numerous purposes, presenting a variety of challenges when it comes to formulating a comprehensive technical dredging strategy. Reasons for dredging include:
