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.
