1. Basic Description

The hull is composed of two buoyant bodies, fully assembled and tested prior to delivery. It can be easily and quickly installed on-site and is ready for operation. It features a standard design, delivered on time and designed in accordance with coastal water standards.

The cutter suction dredger is a widely used equipment in beach reclamation and sand mining projects. It employs a rotating cutter head at the front of the suction tube to cut and stir riverbed sediment, then utilizes powerful pump force to transport the dredged sand and silt materials through conveyance pipelines to the disposal site. Its dredging, conveying, and unloading processes can be completed continuously in one operation. It is an efficient and cost-effective sand and silt excavation device, making it an excellent underwater excavation machine.

The mud pump is driven by the main diesel engine through a gear reduction box.

Emergency pump station units provide lighting and emergency power for the vessel during shutdowns.

The cutter is driven by a hydraulic motor, and the cutter bearing is equipped with a lubrication seal.

The ship is equipped with a hydraulic motor-driven winch and a capstan winch for the crane frame.

定位桩 and trolley are driven by hydraulic cylinders.

Anchor and capstan are driven by hydraulic motors.

The hydraulic pump is driven by an auxiliary machine.
