Ship launching airbags, or inflatable marine airbags. They are made of rubber and are primarily used for launching vessels, towing them back to shore, and assisting in marine salvage operations. This technique was created in the 1980s and is now a flexible and cost-effective alternative to traditional technologies like slipways and dry docks. They are made of layers of reinforced rubber and synthetic cord that meet international requirements like ISO 14409:2011.
Understanding Ship Launching Airbags
Marine airbags for sale are a big step forward in marine tech. We make high-quality airbags for safely moving ships of all sizes.
Ship launching airbags are special inflatable structures for launching and moving ships. They work under pressure to support vessels, making launching and recovering ships safer and more flexible.
Our airbags have an outer rubber layer and an inner rubber layer, with synthetic-tire-cord layers in between. These layers are vulcanized together for strength. Our “Holistic Wrapping Technology” ensures the layers are wrapped at the best angles for even pressure and durability.
Ship launching airbags surpass traditional ship launching methods in many ways. They save money, time, and are flexible for different ships. They also make launching safer and more versatile for modern shipyards.

Types and Technical Specifications of Ship Launching Airbags
Ship launching airbags come in different sizes and types. We offer a detailed look at the various airbags based on their capacity and construction.
- Classification by Bearing Capacity: There are three main types of airbags based on their capacity: QP, QG, and QS. The number of layers affects the airbag’s pressure and performance.
- Size and Dimension Options: Airbags range in diameter from 0.8m to 2.0m and in length from 6m to 18m. The size determines if an airbag is right for a ship.
- Performance Parameters and ISO Standards: Our airbags meet ISO14409 standards and other relevant ones. They’re tested for working pressure, deformation, and safety to ensure they work well.
Applications and Uses of Ship Launching Airbags
Ship launching airbags have changed the maritime world. They’re not just for launching ships but for many tasks, making them key in the industry.
- Ship Launching and Landing Operations: Ship launching airbags are key in moving vessels in and out of the water. They are placed under the ship, inflated, and then controlled to move it safely. This method is efficient and works for ships up to 85,000 DWT.
- Marine Salvage Operations: Marine rubber airbags also play a role in salvaging sunken ships. They help lift and move stranded boats. This method is cost-effective and efficient for complex salvage tasks.
- Vessel Types Compatible with Airbag Launching: Ship launching airbags work with many vessel types. This includes tankers, tugboats, barges, and specialized vessels. The airbag system can be customized for different vessels and launching methods.
