Product Description
Totally Enclosed Inflatable Buoyancy Units for Pipeline Laying
DOOWIN Inflatable Buoyancy Units (IBUs) 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).
