Water Supply Floating Pipeline System For Dredging / Offshore Construction

Floating Pipeline is an advanced marine transfer system engineered for dredging, offshore construction, and port operations. The product integrates a reinforced flow conduit with external buoyancy structures, combining stability, durability, and high load-bearing capacity.

Manufactured using multi-layer synthetic cord reinforcement and abrasion-resistant rubber compounds, the pipeline ensures operational reliability under heavy slurry, sand, and water transport conditions. Its outer surface is UV-resistant, corrosion-proof, and designed to withstand harsh environmental conditions including temperature fluctuations, wave impact, and saltwater exposure.

Diameters range from 150 mm to over 1200 mm, supporting a wide spectrum of dredgers, barges, and offshore vessels. The modular design allows for easy assembly, rapid deployment, and scalable operation across diverse project requirements, offering both safety and cost-efficiency.

A large port reclamation project in Southeast Asia required continuous transport of sand slurry from offshore cutter suction dredgers with capacities exceeding 6,000 m³/h to a reclamation area 2.5 km offshore. Previous rigid pipelines experienced frequent joint failures and seabed interference, causing operational delays and increased maintenance costs.

The deployment of Floating Pipeline provided a flexible and buoyant alternative. With integrated flotation, the pipeline maintained alignment above water, reduced friction loss, and allowed continuous flow despite strong tidal currents.

Over a 14-month operational period, maintenance interventions dropped by 30%, and energy consumption was reduced due to improved flow efficiency. The client reported enhanced safety, as manual handling and underwater adjustments were minimized. Positive feedback highlighted the pipeline's durability and repeatability, with plans to redeploy the system in future dredging campaigns.

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

• Reinforced Structural Integrity: Built with multiple synthetic cord layers, providing exceptional strength under high internal pressure and external mechanical loads. The reinforced carcass prevents deformation or collapse during heavy slurry transport.
• Advanced Abrasion Resistance: Inner lining formulated with wear-resistant compounds capable of handling sand, gravel, and other abrasive materials over prolonged operation.
• Integrated Buoyancy System: Incorporates built-in buoyancy to maintain surface alignment, reducing drag and minimizing mechanical stress on joints.
• Environmental Durability: Outer cover engineered for UV, ozone, and saltwater resistance, as well as temperature fluctuations from -20°C to 60°C.

• Dredging Operations: Efficiently transports slurry from dredgers to reclamation or disposal sites, maintaining alignment and reducing seabed interference.
• Offshore Construction: Used in offshore pipeline installation, foundation works, and sediment transfer in wave-affected zones.
• Port Expansion and Maintenance: Supports continuous material movement during port deepening, dock construction, and sediment removal projects.

• Extensive Industry Experience: Years of experience in marine engineering, delivering pipelines engineered for maximum reliability and safety.
• Customizable Engineering Solutions: Tailored to meet specific project requirements including diameter, length, buoyancy, and reinforcement characteristics.
• Premium Materials and Quality Control: High-grade rubber and synthetic reinforcement materials with rigorous quality inspections to ensure compliance with ISO standards.
• Comprehensive After-Sales Support: Full technical support including installation guidance, maintenance consultation, and troubleshooting.
