DOOWIN Inflatable Buoyancy Units (IBUs) for Pipeline Laying Applications
Specialized Buoyancy Solutions for Pipeline Installation
DOOWIN inflatable buoyancy untis are engineered to provide reliable, controllable buoyancy for pipeline laying operations, including float-outs, beach pulls, and river crossings. Their enclosed design ensures stability in shallow waters while maintaining precise load positioning throughout installation.
Key Advantages for Pipeline Projects
Controlled Buoyancy Adjustment: Air can be added/released in real-time to gently settle pipelines into position or adjust alignment during demobilization.
Shallow-Water Optimization: Low-profile design and circumferential strops accommodate limited depths and load angles up to 15°.
Towing Capability: Stable under tow at speeds up to 2 knots, ideal for pipeline deployment in currents.
Technical Specifications
Materials: High-tensile polyester with UV-stabilized PVC coating; 316 stainless steel Camlock valves.
Safety: 5:1 WLL design (7:1 strops), multiple pressure relief valves.
Efficiency: Shipping weight ≈1% of lift capacity (e.g., 500 tons fits in a 20-ft container).
