Made of synthetic-tire-cord reinforcement layers and rubber layers, our marine airbags represent innovative technology with utmost bright prospect in shipbuilding and marine operations worldwide.
Nanjing Deers Industrial Co., Ltd is the leading supplier of marine airbags in China for over 10 years now. Our airbags have been widely used in Southeast Asia, Europe, Middle-East, North America, Africa, South America. Our expertise, excellent quality and service, flexibility and competitive price satisfy many of our clients.
The marine airbag is made of synthetic-tire-cord reinforcement layers and rubber layers. Including Ship launching airbag, Heavy lifting airbag, Marine salvage airbag. Ship launching airbags are specialized marine airbags used for launching marine vessels, also known as marine airbags.Ship launching airbags can be used for the ship launching or ship landing of tanker, tugboat or barges, carrying vessel, carrier, ferry and other special vessels (AHTS, DSV) and so on. The biggest vessel launched by ship launching airbags up to 100,000 DWT.
Ship launching relying on ship launching airbags is an innovative ship launching technology, compared with “end-on launching”, “side ship launching”, and “float-out”. This ship launching technology overcomes the restrictions of the fixed launching track of side-launch. Ship launching airbags are accepted by more shipyards worldwide because of their advantages of saving time, saving investment, flexibility, and safety.
We offer three main types of marine airbags for different applications and requirements.
A long cylindrical roller bag with hemispherical heads at both ends, generally considered to be innovative technology with utmost bright prospect in shipbuilding. Comparing with traditional ship-launching methods such as side-way launching, this one requires less permanent infrastructure and lower cost.
The most tough pneumatic bags that are used to provide excellent land transport of various heavy & huge structures such as large vessels and heavy loads compared with marine salvage airbags.
They are more flexible and economical than traditional lifting methods like trolley without need of spillway construction. Ideal for moving heavy industrial equipment and structures with minimal friction.
Similar structure to ship launching airbags but featuring optimal designs for salvage and flotation applications taking advantage of stiff and lightweight structure, lifting belts and buckles.
Rubber belts are used to fasten airbags together and buckles make binding much easier. Safe valves automatically release inner pressure when applied in deep water, making them perfect for vessel recovery operations.

Ship launching airbags are constructed of an outer rubber layer, multilayer synthetic-tire-cord layers, and inner rubber layer vulcanized firmly. In addition, the rubber airbags are cylindrical balloon body, with two conical head and end mouth. Swivels and air inlet kits are screwed with end mouth.
Complete mooring solutions including all necessary components for proper installation and performance.

The below”ND-4 and ND-5’’ refer to the number of layers of the synthetic tire cord reinforcement layer. The commonly used air bag layers are 4, 5, 6, 7 and 8 layers. Other layers can also be produced on demand. Synthetic-tire-cord layer is reinforcement layer of the ship launching airbags which are made of rubber coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented “Holistic Wrapping Technology“. To hold the internal pressure and to distribute the stress evenly. DOOWIN use the 1870 dtex/2 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width. The breaking strength is more than 310 N per cords.
