The hull uses dismantle and box-like structure, assembly at working site, which is equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It can also be equipped with anchoring poles and trolley devices to increase capacity. Generally, it has functions on sand dredging, mud dredging, port building and deepening, sand and mud is conveying and discharging by pipeline and floater.
