The pipeline laying floats can be strapped to the pipeline to reduce the tension and weight as pipeline deployment installation buoyancy during the launch of a pipeline. The pipe deployment floats modules also can be used to provide buoyancy when pulling the pipeline underwater.

We manufacture various tie-in pipeline foam buoys to provide the best float solution for the different pipe laying buoyancy requirements. We make the shallow water and deep water pipe deployment floaters down to 300m of depth. If necessary, higher depths can be reached.

To meet the different customer’s requirements, we are making the pipeline foam buoys in two different buoyancy modules. One-piece float and modular floats. Our pipeline foam buoys are fabricated with the different density closed cell foam cell depending on the depth requirement, covered by polyethylene skin/polyurethane elastomer outer skin. The skin also can be reinforced by nylon filament upon request. Each buoyancy modules have banding grooves to secure the buoys to the pipeline. The end fitting can be designed for the easy handling operation. The floats can be fixed on pipes with different types of straps or wire rope according to necessity.

Doowin Marine is a professional manufacturer of ship launching airbags, pneumatic rubber fenders, foam-filled fenders, inflatable pipe plugs, and offshore foam buoys.

Doowin Marine is the leading manufacturer of ISO 14409:2011 or CB/T 3795 rubber airbags/marine inflatable airbags. Marine rubber airbags, known as ship launching airbags or ship launching balloons, can be used for ship launching and landing, heavy lifting, and marine salvage.

Our floating fenders include pneumatic rubber fenders and foam-filled fenders. Our Yokohama-type pneumatic rubber fenders are produced and inspected in compliance with ISO 17357. Our inflatable pipe plugs are widely applicable to all kinds of municipal pipesfor blocking as stoppers. We also produce various offshore foam buoys used for surface-to-sub-sea operations at depths of up to 7000m. 

Our engineers and consultants have been in fabrication and use these products for more than 30 years. Doowin Marine has clients in the ship building, marine rescue and salvage,  energy and oil, offshore shipping, and other industries all over the world. Doowin Marine products passed a rigorous ISO 9001:2008 Quality Management System, approved by the third-party SGS, BV, CCS, ABS, LR, BV.
