This article conducts an in-depth analysis of the pricing mechanism of Trailing Suction Hopper Dredgers (TSHD), sorting out 10 core factors that dominate TSHD pricing ，Focus on a real calculation sheet of how much a TSHD cost.

Yanyang Marine, with 30+ years of expertise, launches the world’s largest customizable modular split‑type CSD (max 2200 m³/h) in 2025. As China’s first and the world’s largest fully electric deep‑water environmental dredger, it offers full design–build–delivery services with IACS design and class supervision, ensuring certification and reliability for medium‑to‑large ecological restoration projects.

A: For domestic coastal engineering vessels (ZC/CCS domestic certificates) such as Split Hopper Barge, Crane Barge, and Deck Barge, Yanyang Marine provides a full one-stop service package to support export and international delivery to foreign buyers. With rich experience in flag registration, one-voyage navigation permit application, communication/navigation safety equipment outfitting, crew deployment, and port provisioning, Yanyang Marine ensures compliance, efficiency, and smooth delivery across global ports.

International clients can rarely charter Chinese dredgers for overseas projects. Major Chinese state-owned dredging companies adopt an EPC+self-execution model and do not charter vessels. Private owners focus on domestic projects and lack international operational capacity. Most Chinese dredgers are dual-use items requiring difficult export licenses, and international dredging involves complex compliance challenges. Practical alternatives: cooperate with Chinese SOEs as EPC contractors, purchase new dredgers from Chinese shipyards such as Yanyang Marine, or engage local international dredging contractors. Direct charter from China is unfeasible; EPC cooperation and vessel purchase are reliable solutions.

This article provides a detailed guide on purchasing a dredger from China. It covers how to find the vessel that best suits your project needs, how to budget correctly, and how to avoid common pitfalls

A: --   Export Sources: Private vs. State-Owned"Generally, dredgers available for export from China are primarily from private fleets. Vessels from State-Owned Enterprises (SOEs) involve complex state asset disposal procedures and stringent compliance requirements, resulting in very f...

When buying dredging vessels from China, key rules and risks apply. State-owned fleets do not export vessels; buyers should target private owners. Most private vessel owners are engineering firms, not foreign-trade enterprises, and cannot handle direct export procedures. Buyers must check for long-idle, poorly maintained vessels that may fail to operate. Dredgers are highly specialized and differ greatly from standard ships. Buyers should only work with dredging-industry specialists and professional brokers.

Dredging vessels typically include cutter suction dredgers, trailing suction hopper dredgers, grab dredgers, backhoe dredgers, split hopper barges, etc. Selecting the appropriate dredging vessel based on different dredging projects, dredging depth, type of material to be dredged, discharge distance, and project scale is the primary task in formulating a dredging implementation plan.

This article provides a detailed overview of the export compliance process for dredging vessels—including various types of dredgers, split-hull mud barges, and self-unloading sand barges (3-in-1 dredger/unloading sand barge, suction sand barge)—as well as the relevant legal framework, such as the Export Control Law, Import and Export Control Regulations, and announcements issued by the Ministry of Commerce and the General Administration of Customs.

This project involves a full marine survey of dredgers and other vessels to assess structural integrity, machinery condition and regulatory compliance, a critical prerequisite for vessel sales and purchases. Conducted by certified class society surveyors or shipowner senior marine engineers, the survey covers: hull visual inspection, ultrasonic thickness measurements (UTM) of vital steel structures, and functional testing of main propulsion and auxiliary systems. It verifies compliance with international conventions (SOLAS, MARPOL, Load Line) and class rules, offering an objective basis for transaction decisions.

A: Currently, Coastal working vessels with ZC certificates can be registered in most countries outside of Europe, the United States, Japan, and Korea. This applies particularly to dredgers, Split Hopper Barges, Piling Barges, Floating Cranes, and ASD Tugboats designed for Coastal and&...

A: The design standards, drawing approval standards, and construction rules&regulations between ZC and CCS are different. By different rules and regulations, It is not possible to convert a vessel with ZC certification to CCS certification unless the modification design is completely r...

A: After submitting all required documents as per MOFCOM requirements, the statutory processing time is 45 working days; however, the actual processing time is usually shorter.

A:Relevant regulations on dredger export controlAccording to Announcement No. 28 issued by the Ministry of Commerce (MOFCOM) and the General Administration of Customs on May 25, 2017, the following dredgers are subject to export control effective June 1, 2017. Without a license, exports are prohibit...
