Custom-Made and ODM Dredging Equipment for Project-Specific Needs
Custom-Made and ODM Dredging Equipment for Project-Specific Needs
Zhenjiang Yanyang Engineering Co., Ltd. (Yanyang Marine) is a professional manufacturer and exporter of dredgers and dredging vessels. The company provides custom-made and Original Design Manufacturer (ODM) production services, enabling buyers to obtain dredging equipment tailored to specific operational requirements in port construction, channel dredging, offshore wind, and inland waterway projects.
Why Standard Dredging Equipment May Not Fit Your Project
Many industrial buyers face the challenge that off-the-shelf dredgers are designed for general conditions, while their projects demand specific drilling depth, discharge distance, soil type handling, class society approvals, or environmental compliance. A standard unit may require costly retrofits or fail to deliver optimal productivity. Custom-made and ODM services close this gap by aligning vessel design, power configuration, and classification with the actual work scope.
Industry Shift Toward Customization
Global dredging projects in deep-water berth construction, large-scale reclamation, and offshore wind foundation installation increasingly require non-standard specifications. Custom-made and ODM dredging equipment allows operators to select the right hull form, pump capacity, dredging depth, and automation level. Yanyang Marine, founded in 1996, has delivered over 30 large dredger construction projects across Asia, Africa, Europe, and the Middle East, demonstrating its ability to execute diverse configurations.
Yanyang Marine's Custom-Made and ODM Capabilities
Custom-made services allow buyers to specify exact technical parameters including dredging depth, discharge distance, installed power, auxiliary systems, and target classification society (CCS, BV, LR, DNV, and others). ODM production services enable clients to leverage Yanyang Marine's engineering team—comprising experienced marine engineers and offshore specialists—to develop a new vessel design from concept, with full intellectual property control retained by the buyer if desired.
The standard production lead time for a custom-made vessel is 2–3 months, faster than typical European manufacturers (which often require 6–12 months). For more complex ODM projects, delivery can be scheduled within 8–12 months. The company’s export ratio is 100%, with main markets including United Arab Emirates, Indonesia, India, Egypt, Turkey, Nigeria, South Africa, Tanzania, Saudi Arabia, and Oman. All vessels are built in compliance with international standards and can be classed by IACS societies.
Step-by-Step Procurement Process for Custom Dredging Equipment
- Requirement definition: Buyer provides dredging depth, soil type, output capacity, discharge distance, operating area, and class requirements.
- Technical proposal: Yanyang Marine’s engineering team develops a customized design including general arrangement, power calculation, pump selection, and structural analysis.
- Contract and milestones: Payment terms typically include escrow deposit plus final payment on delivery (PODA) for standard transactions, or milestone installments / LC for newbuilding projects.
- Construction and inspection: Vessel is built under the supervision of the chosen classification society. Pre-delivery inspection and PODA (Pre-delivery & Onboard Delivery Acceptance) signing occur before shipment.
- Delivery and after-sales: FOB/CIF or vessel delivery at agreed port. On-site commissioning, operator training, and long-term spare parts supply are provided worldwide.
Typical Use Cases for Custom-Made Dredgers
- Port deepening and channel dredging: Trailing Suction Hopper Dredgers (TSHD) with hopper capacity up to 26,800 m³ and dredging depth down to 115 m, suitable for open-sea deep-water channels.
- Land reclamation and hard-soil dredging: Cutter Suction Dredgers (CSD) with capacities from 1,000–8,000 m³/h and discharge distances up to 8,000 m, equipped with heavy-duty cutter heads for rock and clay.
- Confined water and maintenance dredging: Backhoe Dredgers (e.g., Hitachi EX5500) with 15–20.5 m³ bucket capacity and Grab Dredgers with 25 m³ grab capacity, ideal for rivers, harbors, and near-shore operations.
- Material transport: Split Hopper Barges (1,200–3,200 m³) designed for efficient self-unloading in coastal and inland projects.
- Offshore wind and bridge construction: Pile Driving Barges with pile leader height up to 137 m and pile diameter up to 4,000 mm.
Certified equipment—such as the CCS Classed self-discharging hopper barge (Certificate No. ZA23DNB00274)—demonstrates compliance with recognized standards, a critical assurance for buyers evaluating custom-built vessels.
Comparison: Custom-Made/ODM vs. Standard Purchase
| Factor | Custom-Made / ODM (Yanyang Marine) | Standard Off-the-Shelf |
|---|---|---|
| Design flexibility | Full customization of dredging depth, discharge, power, classification | Fixed specifications – limited to existing models |
| Lead time | Standard: 2–3 months; Complex ODM: 8–12 months | Immediate if stock available (may not match project needs) |
| Cost relative to European suppliers | Approximately 50% lower while maintaining high quality | Varies; often higher for European brands |
| Classification | IACS societies (CCS, BV, LR, DNV, etc.) as required | May be limited to one class or no class |
| After-sales support | Global commissioning, training, spare parts, ongoing technical support | Often limited to warranty period; spare parts may be harder to source |
Frequently Asked Questions
Do your custom dredgers come with IACS classification?
Yes, Yanyang Marine’s dredgers can be custom-built and classed by any IACS member society, including CCS, BV, LR, DNV, and others, as specified in the contract. For example, a self-discharging hopper barge was delivered with a CCS Domestic Vessel Classification Certificate (No. ZA23DNB00274).
What parameters can be customized on a dredger?
Buyers can customize dredging depth, discharge distance, installed power, hull dimensions, material (steel, ice-class, etc.), automation level, crew quarters, and auxiliary systems. ODM services also allow full design from concept, including intellectual property retention.
How does the cost compare with European suppliers?
Yanyang Marine’s custom-made dredgers are approximately 50% lower in cost compared to European manufacturers while maintaining equivalent quality, thanks to efficient production and supply chain advantages.
What is the minimum order quantity (MOQ) for a custom vessel?
The MOQ is 1 unit (1 vessel). For standard models, ready-stock may be available; for custom-built, a single vessel order is accepted.
What is the lead time for a custom dredger?
Standard custom vessels are delivered in 2–3 months. For ODM / more complex newbuilding projects, lead time is 8–12 months. Faster delivery is possible for vessels in stock or with minor modifications.
How is after-sales service provided for international buyers?
Yanyang Marine offers worldwide after-sales support including on-site commissioning, operator training, spare parts supply, and long-term maintenance. For more details or to request a proposal for your project, contact our sales team for a consultation or sample quote.
