Foldable Ship Launching Marine Airbags For Pipeline Laying ISO 14409 Standard

The marine salvage rubber aribag is a buoyancy assistance device specifically designed for underwater pipeline installation and maintenance. It features high-strength rubber materials and aerodynamic structures, enabling precise pipeline positioning and buoyancy adjustment through controlled inflation. Its core advantage lies in replacing traditional steel buoys, significantly reducing the complexity and cost of underwater operations while meeting pipeline engineering demands in various scenarios such as deep-sea and shallow environments.
Core Technical Features
‌Modular Design
Supports parallel connection of multiple airbags, with single-point load-bearing capacity reaching hundreds of tons. Customizable to fit pipelines of different diameters (DN300-DN3000).
Foldable structure facilitates easy transportation and rapid underwater deployment, improving installation efficiency by 60% compared to traditional buoys.
‌Environmental Adaptability
Anti-corrosion rubber layer or/and polyester reinforcement ensure a service life of over 10 years, suitable for extreme environments ranging from -30℃ to 80℃.
Low-friction surface design reduces underwater drag force, minimizing pipeline displacement risks.

Application Scenarios
‌Deep-sea Pipeline Installation‌: Achieves pipeline suspension positioning through, reducing risks for divers.
‌Old Pipeline Repair‌: Assists in replacing damaged pipeline sections, avoiding large-scale excavation construction.
‌Tidal Zone Operations‌: Adapts to water level changes, ensuring pipeline stability in tidal environments.
Customer Value
‌Cost-effectiveness‌: Overall costs are 40% lower than steel buoys, with maintenance manpower reduced by 50%.
‌Safety‌: Zero-leakage sealing structure certified by ISO 9001, eliminating underwater accident hazards.
‌Sustainability‌: Materials have a 90% recyclability rate, complying with EU CE environmental standards.

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.
