1. Basic Description

The hull is composed of two floats, fully assembled and tested prior to delivery. It can be easily and quickly installed on-site and is ready for operation. Standard design, timely delivery, and compliant with coastal water standards.

The cutter suction dredger is a widely used piece of equipment in reclamation and sediment removal projects, as well as sand mining operations. It employs a rotating cutter head at the front of the suction tube to cut and stir riverbed sediment, propelling the collected material through a pipeline to a sediment pile-up area using its powerful pump. Its dredging, transporting, and unloading processes can be completed in a single continuous operation. It is an efficient and cost-effective sediment 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 ship during downtime.

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

The winch for lateral movement and the hoisting winch of this vessel are both powered by hydraulic motors.

Piling locators and trolleys are driven by hydraulic cylinders.

Anchor and chain winches are powered by hydraulic motors.

Hydraulic pumps are driven by auxiliary machinery.
