Product Usage
Dredging Project
Channel Dredging: Removal of silt, sand, and gravel from ports, rivers, and canals to maintain navigable water depths.
Land reclamation: Submarine sand and gravel are dredged and hydraulically pumped for fill, used to construct artificial islands or expand coastlines.
Subsea mining: conveying seabed minerals such as placer gold, tin sand, and phosphate rock.
Vessel operations
Bilge dewatering: Removing sedimentary sand and gravel from cargo holds or ballast tanks.
Core equipment of dredgers: As a critical pump type for cutter-suction and dragline dredgers, it directly pumps underwater sediment.
Marine Engineering
Subsea pipeline installation: scouring seabed trenches and backfilling with sand and gravel.
Breakwater construction: transporting stone, concrete aggregates, and other construction materials.
Emergency rescue and disaster relief
Clearing port sediments after floods or typhoons.
Sediment suction operations during shipwreck salvage.
