The latest news about the cutter suction dredger 

As a core piece of equipment in modern dredging engineering, cutter suction dredger/cutter suction sand dredger/cutter suction mud dredger has made significant progress in recent years in terms of intelligence, green technology, and large-scale production. Based on the latest industry trends and technological breakthroughs, the following are some of the most noteworthy development trends and representative equipment information:

I. Intelligent Upgrade: AI-Driven "One-Click Dredging" Becomes a Reality 

Currently, high-end cutter suction dredger/cutter suction sand dredger/cutter suction mud dredger is widely equipped with intelligent dredging systems, using artificial intelligence algorithms to achieve automatic optimization, anomaly identification, and dynamic adjustment of construction parameters.

The "Intelligent Dredging System for Cutter Suction Dredger/cutter suction sand dredger/cutter suction mud dredger" developed by CCCC Dredging has been installed on the "Xin Haijiao" and "Xin Hailu" series of vessels. Real-world testing data shows that compared to manual operation, construction efficiency is increased by more than 15%, and control accuracy and stability are significantly enhanced.

CCCC Tianjin Dredging Bureau has applied for a patent for "Cutter Suction Inlet Position Density Prediction," which, through real-time data modeling, predicts slurry concentration in advance, significantly improving construction control accuracy.

II. Representative Ship Types: Performance Parameters Continuously Breaking Records 

1. "Haohailong" (Asia's Largest)

Total Installed Power: 26,443 kW (Asia's First)

Maximum Cutter Power: 7,800 kW

Maximum Dredging Depth: 38 meters (Asia's Deepest)

Discharge Distance: 15 kilometers

Features: Equipped with three types of specialized cutterheads, capable of excavating moderately weathered rock with a compressive strength up to 50 MPa, suitable for port and waterway dredging and reclamation projects. 

2. "Tianjing" (China's First Ultra-Large Self-Propelled Cutter Suction Dredger)

Dredging Capacity per Hour: 4,500 cubic meters

Maximum Discharge Distance: 6,000 meters

Excavable Rock Compressive Strength: 40 MPa

Status: Formerly the largest in Asia and the third largest in the world, it has participated in major projects such as the Pinglu Canal.

III. Technological Breakthroughs and Market Layout of Domestic Manufacturers

Companies such as Qingzhou Yongli Mining And Dredging Machinery Co., Ltd. are accelerating technological iteration and demonstrating competitiveness in the international market: 

Patents and Standards: Possessing 70 national patents, and leading the formulation of the "Dredging Equipment Industry Processing and Manufacturing Standards".

Intelligent Configuration: Equipped with GNSS navigation and AI sediment stratification identification system, positioning error <0.5 meters, and energy consumption reduced by 30%. Environmental Innovation: Utilizing on-site sludge solidification technology reduces sludge dump space by 300 mu (approximately 20 hectares), meeting international ecological dredging standards.

Global Services: Products are exported to over 80 countries, participating in international projects such as the UAE naval port and Maldives land reclamation.

IV. Policy and Export Regulations Updates

According to General Administration of Customs Announcement No. 9 of 2026, starting in 2026, export declarations for dredgers require stricter regulations: Cutter suction dredger/cutter suction sand dredger/cutter suction mud dredger  must specify the following on the customs declaration: cutter head power, dredging depth, and total installed power. If the item is subject to export controls, it must be marked "Subject to export controls" and the dual-use item code must be listed.

This policy aims to strengthen the management of high-end equipment exports and prevent the risk of technology spillover.
