Dredging and waterwork projects are usually described in the field — silt depth, sand volume, weed coverage, site access — not in vessel terminology. From our plant in Qingzhou, a Chinese dredging equipment manufacturing base, Shandong WanRun Intelligent Equipment offers 104 products across 10+ series and has customized equipment for more than 100 clients. This page maps what you see on site to the equipment families typically considered, before our engineers review your specific conditions.
Equipment suggestions on this page are preliminary. Final suitability is always confirmed by our engineering team against your project data.
Choose the problem closest to your project. Each entry lists the conditions that matter most.
Soft silt and mud reduce navigation depth or storage capacity. Typical candidates: cutter suction dredger (6–24 in, up to 4,000 m³/h) and amphibious crawler equipment.
Loose or consolidated sand and gravel deposits. Typical candidates: jet suction, water-jet and bucket chain sand dredgers.
Dense water hyacinth, weeds or reeds on shallow, soft-bottom water. Candidate: amphibious waterway cleaning vessel with cutting and collection heads.
Sediment re-accumulation around berths and basins. Electric remote-controlled trailing suction hopper dredgers work to 10 m depth; final choice depends on soil, tides and disposal plan.
Before comparing models, gather these six inputs. They change the answer more than brand or budget does.
Soft silt, cohesive clay, loose sand, compacted gravel or rock. Hardness and composition drive the cutter, pump or bucket choice.
Minimum and maximum water depth, and how it changes with tide or season. Our range spans shallow amphibious work to 30 m custom deep dredging — confirm against the spec sheet.
Channel width, turning area, bridge heights and shore slope. Compact sites may rule out larger hulls or long pipeline layouts.
Onshore discharge through pumping and pipeline, hopper barging or beneficial reuse. Distance and elevation determine pumping and pipeline needs.
Road, container or coastal towage to reach the site. This affects hull form, disassembly design and delivery method.
Environmental permits, working windows, power supply on site and crew availability. Some conditions require engineering review before any model is proposed.
The mapping below is a starting point for discussion, not a commitment.

Delivered & commissioned450 type cutter suction dredger deployed on river and lake desilting duty.
Operational — customer reportBatch delivery of three electric remote-controlled hopper dredgers: 10 m dredging depth, clean-water discharge 100 m³/h.
Batch deliveredAttach material type, depths, discharge plan and site photos if available. We reply with a candidate configuration and the conditions it still needs to confirm — never a generic catalogue answer.
