Hydraulic cutter suction dredger plays a key role in many fields with its unique working mode and performance advantages.
1. Port construction and maintenance
Port channels need to be dredged regularly to ensure the safe navigation of ships. Hydraulic cutter suction dredgers can efficiently remove obstacles such as silt and reefs deposited at the bottom of the channel to ensure that the channel has sufficient water depth and width. For example, in large container ports, with the development of large-scale ships, the requirements for channel water depth are constantly increasing. Cutter suction dredgers deepen and widen the channel through precise excavation and long-distance mud discharge operations to meet the needs of giant ships entering and leaving the port. At the same time, in the frontier waters and harbors of port terminals, it also relies on it to maintain a suitable water depth to prevent the normal operation of the terminal from being affected by silt siltation.
2. Water conservancy engineering field
River regulation projects, can dredge the bottom of the river, improve the flood discharge capacity of the river, and reduce the risk of water level rise and overtopping caused by river siltation during flood season. For some lakes and reservoirs that have become shallow due to siltation, the operation of the cutter suction dredger can restore their water storage capacity and enhance the regulation and storage function of water conservancy facilities. In addition, in the foundation construction of water conservancy hub projects, such as the foundation excavation of dams, it can accurately dig out the foundation shape that meets the design requirements underwater, laying a solid foundation for subsequent engineering construction.
3. Sea reclamation project
It can excavate silt, soft soil, and other materials on the seabed and transport them to designated areas through long-distance mud pipes, gradually accumulating to form land. In the development process of coastal cities, in order to expand urban space, build industrial development zones or new residential areas, sea reclamation projects continue to emerge, and the cutter suction dredger undertakes the key task of land reclamation, converting marine resources into land resources that can be developed and utilized.
4. Offshore oil and gas field development
Hydraulic cutter suction dredgers are also useful. They can level and dig the seabed in the foundation area of the offshore platform to create stable seabed foundation conditions for the construction of the platform. At the same time, when laying submarine pipelines, it can dredge the pipeline laying path in advance to ensure that the pipeline can be laid smoothly at the designed location to avoid the installation and operation of the pipeline affected by the undulating seabed terrain or obstacles.
