DredgingWhy choose Anaconda for dredging applications
Anaconda delivers integrated hose and pipe systems that are field-proven in large-scale dredging, reclamation, sediment removal, port deepening, and inland waterway maintenance. Our product range is built around three essential requirements for dredging:
- Consistent, high-volume slurry flow
- Superior abrasion and pressure resistance
- Quick assembly, flexible routing, and reduced operational interruptions
HDPE pipe ensures long-run stability, slurry hose manages high-wear discharge and suction zones, and lay-flat hose provides rapid-deploy options for temporary flows and support lines. The result is a cohesive dredge conveyance system suitable for harsh marine and river environments.
Industrial Slurry Hose for high-wear dredging environments
Use cases: pump discharge, suction hose on cutter suction dredgers, flexible connections near elbows, joints between floating pipelines, barge-to-shore transitions.
Key features

Case study
Delivering reliable slurry transport for a coastal dredging project
Client Overview
A marine civil contractor was tasked with extending a port channel and transporting large volumes of sand to a reclamation site nearly one kilometer away. The project required a slurry conveyance system capable of handling high abrasion, movement of floating pipelines, and rapid assembly in shifting tidal conditions.
Project Challenge
The contractor needed:
- A durable discharge line for long-distance slurry transport
- High-wear components near the dredge pump capable of handling constant movement
- Temporary water-transfer lines to manage return water during operations
- Fast installation to meet a tight dredging window
Existing hoses on the dredger showed significant wear, and previous steel pipeline sections required frequent maintenance, creating risk of downtime.
Implementation and Performance
The full pipeline system was installed in less than two days.
Outcomes included:
- Stable slurry movement with no leakage incidents
- Zero hose failures despite continuous heavy solids pumping
- Reduced fuel consumption due to improved hydraulic efficiency
- Faster work cycles thanks to simplified hose handling
Anaconda Solution
Anaconda supplied a complete dredging conveyance package consisting of HDPE pipe, slurry hose, and lay-flat hose.
1. HDPE Pipe for Main Discharge Line
DR17 HDPE pipe was deployed along the floating and land sections. Its smooth bore improved pump efficiency and reduced head loss, while its corrosion and abrasion resistance ensured uninterrupted flow.
2. Slurry Hose for High-Abrasion Zones
Industrial slurry hose was installed at the pump outlet and at pipeline transitions. The reinforced construction supported suction and discharge forces, absorbed vessel movement, and eliminated premature hose failures.
3. Lay-Flat Hose for Return Water and Support Lines
Heavy-duty lay-flat hose enabled quick rerouting of return water and served as temporary piping during dredger repositioning. Its portability minimized delays.
Results
- Project completed ahead of schedule
- Lower maintenance cost throughout operations

Frequently Asked Questions
What pipe and hose solutions does Anaconda recommend for dredging applications?
Anaconda recommends using HDPE pipe for long-distance discharge lines, industrial slurry hose for high-abrasion suction and discharge points, and lay-flat hose for temporary or rapidly deployable water transfer requirements.
Why is HDPE pipe widely used in dredging discharge systems?
HDPE pipe provides low friction, high abrasion resistance, corrosion resistance in marine environments, and long continuous lengths that reduce leak points. Its durability and smooth bore make it effective for transporting sand, silt, and slurry over long distances.
Can Anaconda slurry hose handle heavy solids and abrasive dredge material?
Yes. Industrial slurry hose is designed with abrasion-resistant liners and reinforced structure to handle sand, gravel, silt, and high-density slurries. It performs reliably in both suction and discharge roles commonly found on dredging vessels.
How does lay-flat hose support dredging projects?
Lay-flat hose offers fast deployment for temporary bypass lines, return-water routing, flushing lines, and auxiliary flows. It is lightweight, easy to store, and ideal for short-term operations where mobility is required.
Are Anaconda products compatible with standard dredging pumps and fittings?
Yes. HDPE pipe and slurry hose can be supplied with flanged ends that interface with dredge pumps and pipeline systems. Lay-flat hose is available with Bauer, camlock, and hose-tail fittings for compatibility with portable pumps and support equipment.
Can these products be used in both marine and inland dredging operations?
Absolutely. The materials and construction are suited to coastal dredging, river and lake sediment removal, port deepening, reclamation projects, and inland waterway maintenance.
What factors determine whether to use HDPE pipe or slurry hose?
HDPE pipe is ideal for long, straight discharge runs requiring low friction and high durability. Slurry hose is preferred near the dredge pump, at bends, transitions, or anywhere flexibility and abrasion tolerance are essential.
How quickly can Anaconda systems be installed on a dredging project?
HDPE pipe is delivered in modular lengths for fast joining, while slurry hose and lay-flat hose allow quick connections around pump interfaces and temporary routes. Contractors often assemble full discharge lines within hours or a few days depending on length.
Can Anaconda provide custom lengths or configurations for dredging pipelines?
Yes. HDPE pipe, slurry hose, and lay-flat hose can be supplied in custom lengths with selected fittings, flange types, and reinforcement levels tailored to project specifications and pump performance.
Are these hoses and pipes suitable for floating pipeline systems?
Yes. HDPE discharge lines are commonly fitted with floats for use as floating pipelines. Slurry hose sections are used near the dredger and at pipeline joints to absorb movement and vibration. Lay-flat hose may also support temporary floating routes for water transfer.
How do these products perform under continuous high-pressure conditions?
HDPE pipe withstands sustained discharge pressures based on its DR rating, while slurry hose is reinforced for both suction and discharge loads. Both products maintain structural integrity under the high-pressure cycling common in dredging operations.
Do these solutions reduce maintenance requirements in dredging operations?
Yes. The abrasion-resistant construction, corrosion-proof materials, and reduced number of joints help minimize wear, leaks, and downtime. This leads to lower lifetime maintenance costs and more reliable dredging cycles.
