Hopper Dredgers. Usually shipform in design, a hopper dredger deposits the dredged material in an onboard hopper for transportation. Both mechanical and hydraulic designs are common for loading the hopper as well as for discharging the dredged material. Trailing Suction Hopper Dredge.
· Sand mining dredgers create sand bars, restore beaches and more. IMS and its affiliates are the largest group of dredge companies in the Americas and have over 200 years of collective experience in the design and manufacture of hydraulic dredging systems.
Trailing suction hopper dredgers. The trailing suction hopper dredger found acceptance in all parts of the world in a relatively short period. Before the 1960s, this type of dredger was hardly ever used. But as the number and size of oceangoing ships increased, wider and deeper channels and harbour basins were required to accommodate them. The trailing dredger is the perfect answer, as it ...
A Trailing Suction Hopper Dredger is a selfpropelled vessel, used for maintaining or deepening waterways, or to dredge sands to replenisch beaches or to be used for construction purposes on land, thereby using powerful pumps and deploying one or two suction pipes fitted with a draghead, which are lowered onto the seabed, whilst moving slowly forward. The dredged materials are held in its ...

The dredgers are equipped with a single highpressure submerged dredge pump, mounted on the ladder. This high efficiency pump is directly driven by the diesel engine, via the IHC Pivoting Gearbox. The prime mover for the dredge pump is a modern computer controlled diesel engine with low fuel consumption, and low NOx and soot emissions. The main engine was overhauled in March 2016 and .
Two side cutters are used to increase sand heavyduty cutters enable the pump to break up very compact material, ensuring the continuous feeding of the suction pump. The agitator and optional cutter knife inside the pump chop all types of organic material like seaweed, grass, and other aquatic weeds to ensure maximum suction power. The suction power of the dredge pump can handle ...
