A Cutter Suction Dredger (CSD) is a vessel that is utilized for excavating and removing sediment, mud, and other materials from waterways and bodies of water. It utilizes a rotating cutter head to break up the material and a suction pipe to transport it to a discharge location. CSDs are employed in a variety of applications, such as the construction and maintenance of ports, harbors, and other coastal structures, the creation of artificial islands and beaches, deepening navigational channels, and extracting minerals like sand and gravel for construction projects.

Our CSDs are designed to be highly efficient and effective at dredging hard materials, like rock, clay, and silt. We provide a range of sizes from 6 to 20 inches, making them adaptable to different project requirements and site conditions. Our vessels can be customized based on dredging depth, working capacity, and discharge distance, with capabilities that range from 15 meters in dredging depth and a maximum flow rate of 6000 cubic meters per hour.

We manufacture our cutter suction dredgers using high-quality materials and components to ensure their longevity and offer comprehensive support services to our customers, including dredger design and engineering, construction packages, local installation, and all necessary parts packaged in containers for shipping to the customer's overseas yard.

In addition to manufacturing cutter suction dredgers, we provide ongoing maintenance and repair services to ensure that our customers' equipment remains in good working condition. We offer regular maintenance packages as well as emergency repair services if needed.

When considering a cutter suction dredger for a project, it is important to take into account the environmental impacts, cost and efficiency, maintenance and repair requirements, and safety considerations. Our team can work with customers to provide guidance and support in these areas to help ensure a successful dredging project.

Examples of cutter suction dredger projects include the expansion of ports and harbors, the creation of new islands and beaches, and the extraction of minerals such as sand and gravel for construction projects. Our cutter suction dredgers have been used in a variety of projects around the world.

Overall, our cutter suction dredgers offer a versatile and powerful tool for dredging hard materials in waterways and bodies of water. With our comprehensive support services and expertise, we can help customers to achieve their project goals efficiently and effectively.
