FAQ

A: We manufacture various types of dredgers, including cutter suction dredgers, bucket chain dredgers, jet suction dredgers, sand dredgers, gold dredgers, and other dredging vessels and equipment. Customized dredging solutions are also available based on different project requirements.

A: The right dredger model depends on factors such as dredging depth, required production capacity, sediment type, discharge distance, water conditions, and project requirements. Our engineers can recommend or customize the most suitable dredger based on your specific working conditions.

A: A cutter suction dredger (CSD) uses a rotating cutter head to cut and loosen underwater sediment. The material is mixed with water to form slurry and then transported through a discharge pipeline. It is widely used for river dredging, sand mining, port construction, waterway maintenance, and land reclamation.
A bucket dredger uses a continuously moving chain of buckets to excavate and lift underwater sand, gravel, or mineral-bearing materials. In addition to dredging, it is commonly used for sand mining, mineral extraction, and underwater mineral processing, especially for projects that require continuous excavation, lifting, and material feeding.
The right choice depends on material type, dredging or mining depth, required capacity, mineral characteristics, discharge or feeding method, and specific project requirements.

A: The maximum dredging depth depends on the dredger type, model, ladder length, pump configuration, and project requirements. Our dredgers can be customized for different dredging depths, and we can provide suitable configurations based on your specific working conditions.

A: The maximum discharge distance depends on the dredger model, slurry pump capacity, pipeline diameter, sediment characteristics, and site conditions. Our dredging systems can be customized for different discharge distances, and booster pump stations can be added when longer-distance slurry transportation is required.

A: Yes. We support OEM and ODM customization for dredgers and related equipment. We can customize the dredger size, dredging depth, production capacity, discharge distance, engine, slurry pump, pipeline system, and other configurations according to your project requirements.

A: We can produce approximately 30–40 dredgers and workboats per year, depending on the vessel type, specifications, and customization requirements. Our production capabilities allow us to manufacture customized dredging vessels and related equipment for different project requirements.

A: The price is mainly determined by the dredger type, production capacity, dredging depth, discharge distance, engine and pump configuration, hull size, and customization requirements. We provide project-based quotations according to the customer's specific requirements and working conditions.

A: Our quotation generally includes the dredger or vessel, main equipment, engine and pump configuration, standard onboard systems, and other equipment specified in the project requirements. The exact quotation scope depends on the vessel type, configuration, and customization requirements. Shipping, installation, commissioning, and other services can be quoted separately if required.

A: Payment terms can be discussed and agreed upon based on the order value, vessel type, production schedule, and project requirements. We work with customers to establish a suitable payment schedule before production begins.

A: There is no fixed minimum order quantity (MOQ) for our dredgers and workboats. We can manufacture single vessels or multiple vessels according to the customer's project requirements, vessel specifications, and production plan.

A: Our company is qualified for Grade Ⅲ shipbuilding and can provide vessel construction in accordance with applicable requirements. Our vessels can also be designed, manufactured, and inspected according to CCS (China Classification Society) requirements, depending on the vessel type and project specifications.

A: We ensure quality through professional engineering design, standardized manufacturing processes, quality inspections, and testing throughout production. Our shipbuilding process follows applicable industry standards and requirements, and CCS inspection and certification can be arranged according to the vessel type and project requirements. Each vessel is inspected and tested before delivery to ensure that its main systems and equipment meet the agreed specifications.

A: We provide a one-year warranty for our dredgers, workboats, and related equipment. The warranty covers manufacturing defects and quality issues under normal operating conditions. Specific warranty terms and coverage are subject to the sales contract.

A: The service life of the dredge pump and cutter head depends on factors such as material hardness, sediment abrasiveness, operating conditions, working hours, and maintenance. We use wear-resistant materials and components to improve service life, and replacement wear parts are available when required. For projects with highly abrasive materials, we can recommend suitable wear-resistant configurations.

A: The typical delivery lead time is 3–4 months, depending on the vessel type, specifications, equipment configuration, and customization requirements. The exact delivery schedule will be confirmed before production begins.

A: Large dredgers are usually shipped by bulk carrier, heavy-lift vessel, or semi-submersible vessel, depending on the dredger size, structure, and destination. For some projects, the dredger can also be disassembled into transportable sections for easier shipment and then assembled at the destination. We can arrange suitable transportation solutions based on the vessel specifications and delivery location.

A: The on-site assembly time depends on the dredger size, vessel structure, equipment configuration, and site conditions. For standard configurations, assembly and commissioning can usually be completed within several weeks. Our technical team can provide on-site guidance or installation support when required.

A: Yes. We provide operator training and technical guidance for our dredgers and related equipment. Training covers equipment operation, daily maintenance, safety procedures, and basic troubleshooting. Training arrangements can be discussed according to the project requirements.

A: We provide remote technical support and after-sales service for overseas customers through video calls, phone, email, and online communication. Our technical team can assist with equipment installation, commissioning, operation, maintenance, and troubleshooting. On-site technical support can also be arranged when required, depending on the project and service requirements.

A: We maintain a supply of commonly used spare parts and wear parts for our dredgers and related equipment. Customers can order replacement parts directly from us when needed. We also provide technical guidance for parts selection and replacement to help ensure reliable equipment operation and minimize downtime.

A: Yes. Our dredgers and related equipment can be upgraded or retrofitted according to project requirements. Depending on the vessel structure and existing configuration, we can upgrade systems such as the dredge pump, cutter head, engine, hydraulic system, pipeline system, and other equipment to improve production capacity or adapt to new working conditions.

A: Yes. Our dredgers and related equipment can be designed and configured to meet applicable environmental, safety, and emission requirements for different projects and operating regions. We can also adjust the engine, hydraulic system, slurry handling system, and other equipment configurations according to local regulations and project requirements.
