Water Supply Floating Pipeline System Anti Corrosion For Dredging Land

Floating Pipeline is a high-performance marine transfer system engineered for dredging, land reclamation, and offshore construction projects. It features a multi-layer reinforced synthetic structure with an abrasion-resistant inner lining and integrated buoyancy, combining durability, flexibility, and load-bearing capacity.

The pipeline maintains alignment on water surfaces, minimizing drag and reducing mechanical stress on joints. Diameters range from 250 mm to 1200 mm, supporting small river dredgers and offshore vessels with capacities exceeding 7,500 m³/h. The outer cover is resistant to UV radiation, saltwater corrosion, and temperature variations (-25°C to 65°C). Modular sections enable quick deployment, ease of maintenance, and scalable operation for various project sizes.

An offshore reclamation project in the Gulf of Mexico required continuous transport of sand and sediment slurry from dredgers with capacities of 7,000 m³/h over a distance of 3 km. Rigid pipelines previously used suffered joint failures and abrasion, resulting in operational delays.

Floating Pipeline was deployed, leveraging its integrated flotation to maintain surface alignment and reduce mechanical stress. During 18 months of operation, flow efficiency improved by 22%, maintenance interventions decreased by 40%, and energy consumption was reduced due to the low-friction lining. Operators reported enhanced safety with minimal manual handling. The modular design enabled easy replacement of worn sections, supporting repeated deployment for seasonal dredging campaigns.

Note: Various sizes can be customized according to the requirements.

• High Structural Strength: Multiple layers of synthetic cord reinforcement provide exceptional strength under heavy slurry loads and high internal pressure. This prevents kinking or collapse during long-term offshore or port operations.
• Advanced Abrasion Resistance: The inner lining is formulated from wear-resistant rubber compounds capable of handling sand, gravel, and high-density sediment, reducing downtime and extending operational life.
• Integrated Buoyancy System: Built-in flotation maintains pipeline alignment on water surfaces, reducing drag, minimizing joint stress, and ensuring stable flow even in wave-affected or tidal conditions.
• Environmental Durability: The outer cover resists UV, ozone, saltwater, and extreme temperatures, ensuring consistent performance in tropical, temperate, and offshore environments while lowering lifecycle maintenance costs.

• Port and Channel Maintenance: Used for continuous sediment removal, channel deepening, and port expansion to maintain safe navigation for large vessels.
• Offshore Construction: Supports slurry and fluid transfer for foundation laying, reclamation, and pipeline installation projects in marine environments.
• River and Canal Dredging: Floating Pipeline efficiently moves sediment while floating above the seabed, reducing wear and maintenance needs.

• Proven Offshore Engineering Expertise: Years of experience allow Hongruntong Marine to engineer pipelines that perform reliably under demanding offshore and port conditions.
