Continuous inflatable tube attached directly to the cable or pipe, eliminating point loads and providing uniform support along the entire length for cable installation and shallow‑water pipe launching, towing, and floating.
This inflatable tube is a continuous inflatable buoyancy system designed for cost-effective and efficient cable/pipeline installation. It replaces traditional individual floats with a single tube attached directly to the cable at 1–1.2m intervals, providing uniform support and eliminating point loading.
The system can be rolled onto standard pallets, deploys rapidly from a braked drum, and allows surface control of sinking and re-floating. Operators can pause cable laying during adverse conditions, lift cables to hit trenches, or tow sections several kilometres. It operates at less than half the cost of solid buoyancy, suits ultra‑shallow water (e.g., swamps), and can be vented remotely to place the pipe gently on the seabed.

DOOWIN is committed to providing high quality proof-load testing water weight bags and air lifting bags for our customers worldwide.
Mono buoyancy units enable efficient pipeline/surface operations with time-saving single-point connections and wide-angle adaptability.
Inflatable buoyancy units can be used for surface marine salvage, pipe-laying buoyancy floats, and vessel draught reduction.
Twin-boom and twin-chamber designs are used for small-diameter pipelines, cables, and hoses.
Inflatable cable and pipeline floats are ball-type design for small-diameter cable and pipeline laying.
We provide professional pipe laying and cable laying solution with our inflatable buoyancy units. Various inflatable buoyancy bags are used for pipe lay, cable lay, pipeline shore landing, and cable shore landing.
