History of Dredging. With the beginning of civilization, commodities were transported by inland waterways and oceans. But this transportation depended on the ability of ships, which in turn largely depended on the water depth.. Silting, the natural phenomenon of deposition of silt and sediments over the sea bed, created a constant threat to the voyages of …

The trailing suction hopper dredge is a self-propelled seagoing ship equipped with a suction pipe, which trails over the side of the vessel or through a well in the hull. The sediment and water slurry is transported through the pumps just as the pipeline dredge, but when the sediment and water slurry passes through the pump to the discharge ...

Spain's automobile industry requires efficient water management for manufacturing processes such as stamping, welding, and painting. Pumping systems provide water for cooling machinery and parts during production. Dredging activities prevent sediment buildup in cooling systems and wastewater discharge channels, ensuring uninterrupted manufacturing operations.

The name trailing suction hopper dredger (TSHD) refers to the fact that this type of vessel dredges while slowly sailing, trailing one or two suction arms off the side of the hull. At the entrance of each suction arm, a drag head is connected. This drag head collects the soil like the mouth of a vacuum cleaner. TSHDs are mainly used to dredge sand, silt and gravel.

A marine vessel fitted with a device(s) to scrap or suck the sediment deposition over a sea bed is known as a dredger (The device used for excavation and scraping of the sea bed is called the Dredge). In a more general sense, a ship equipped with an excavation tool that is capable of weeding off depositions such as sand, gravel, sediments, etc ...
