The HID Cutter Suction Dredger Demonstrates High Efficiency And Environmental Protection Capabilities in Reservoir Dredging Construction.

The HID cutter suction dredger demonstrates high efficiency and environmental protection capabilities in reservoir dredging construction.

The HID series cutter suction dredgers independently developed and manufactured by HID Shipyard have successfully completed the phased construction tasks in the dredging projects of key reservoirs in China, demonstrating excellent operational efficiency and environmental protection performance. They have provided strong equipment support for increasing the reservoir capacity and improving the water ecological environment.

As an important water source and flood control and storage hub in the region, this reservoir has suffered from severe siltation at the bottom after years of operation, which directly affects water supply safety and flood control capacity. The water depth of the construction area this time varies greatly and the bottom material is complex, which puts forward high requirements for the passability, excavation accuracy and environmental protection control of the dredger.

The HID cutter suction dredger, with its high-strength cutter system and precise positioning control technology, achieves efficient crushing and stable suction and transportation during construction. The average daily dredging volume meets the design expectations, and the sludge transportation distance meets the requirements of long-distance sites. Meanwhile, the hull adopts a modular design, which is convenient for on-site disassembly and assembly, and can adapt to the narrow working surface and frequent ship movement conditions of the reservoir.

In terms of environmental protection, the HID dredger is equipped with a diffuser hood and a low-disturbance cutter, effectively suppressing the diffusion of sediment during construction. The increase in suspended solids is far lower than the industry standard, maximizing the protection of the water body ecology of the reservoir. During the construction period, the third-party water quality monitoring data remained consistently stable within the allowable range, earning recognition from the owner and the environmental protection department.

HID Shipyard is always committed to providing efficient, reliable and green dredging equipment for environmentally sensitive water areas such as inland rivers, lakes and reservoirs. The successful practice of this reservoir construction further verified the engineering adaptability of the HID cutter suction dredger in complex environments and also provided a replicable technical solution for similar dredging projects.
