NEW TSHD
Trailing Suction Hopper Dredger (TSHD) is an efficient dredging vessel that integrates excavation, transportation, and unloading functions, commonly used for channel widening, port maintenance, and land reclamation projects. It operates by towing a draghead along the seabed to suction up sediment, silt, or sand into its hopper, then sailing to a designated area to discharge the material by self-unloading, bottom dumping, or pumping through pipelines. This type of vessel features strong continuous operation capability, flexible navigation, good performance in rough seas, and wide adaptability to various water environments, making it especially suitable for large-scale, high-efficiency dredging operations.

— Application
1. Inland & Nearshore Channel Maintenance
Removing sediment from rivers, lakes, and nearshore channels to ensure safe navigation.
Regular maintenance of waterway depths to prevent silting and maintain traffic flow.
2. Coastal Port Dredging
Dredging port and berth areas to increase handling capacity.
Supporting port expansion projects by optimizing berth depth and waterway access.
3. Deep-Water Channel Expansion
Widening and deepening main channels to accommodate large vessels (e.g., container ships, oil tankers).
Improving navigability and safety in deep-water routes.
4. Offshore Works & Land Reclamation
Providing dredging support for offshore constructions, such as wind farms and oil & gas platforms.
Sand excavation, transport, and placement for land reclamation and artificial island construction.
5. Large-Scale Infrastructure Projects
Supporting large coastal reclamation and urban infrastructure projects (e.g., Singapore land reclamation).
Dredging and infilling for major ports, industrial zones, and coastal developments.
6. Ultra-Deepwater Projects
Conducting dredging operations in depths of 60–100+ meters.
Suitable for oilfield access channels, ultra-deepwater shipping lanes, and specialized marine passages.
— Advantage and Customization
Technical Configuration:
Equipping the vessel with a submerged pump can increase the maximum dredging depth by approximately 30–50%, significantly enhancing deep-water operation capability.
Geological Adaptability:
When operating in hard clay conditions, the required power increases by around 20% compared to loose sandy soils, ensuring efficient cutting and material transport.
Environmental Compliance:
Vessels meeting the EU Tier IV emission standards typically require power optimization of about 10–15% to balance environmental performance with operational efficiency.
The above figures represent average values for mainstream vessel types currently on the market; actual specifications should be confirmed according to the shipyard’s technical documentation.
Newbuild trends are moving towards electrification and the adoption of intelligent dredging systems, which can automatically optimize dredging paths to achieve energy savings and precise operations.
For detailed technical documentation or shipyard recommendations for specific tonnage vessels, further targeted analysis can be provided.
