Ship launching or upgrading using marine airbags is an innovative technology that has the utmost bright prospect in shipbuilding. It overcomes the disadvantage of fixed track launching by which the productivity of shipbuilding and ship repairing were limited in the small-sized and medium-sized shipyards.

This flexible launching technology is highly versatile and helps companies in the shipbuilding and maritime industry save effort, time, work load and investment. Our  engineering team is constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety and reliability.

• For ship upgrading, conversion or new/repair launching (Ship launching airbags)
• For hoisting and transporting heavy structures up to 10,000 metric tons
• Possible substitute for marine pneumatic rubber fender for protective purposes
• For salvaging sunken ship or heavy immersed steel structure
• Pneumatic rubber core for architecture engineering
• Container for storing and transporting gas and corrosive chemical liquid and pure water for voyage
• Rubber bag for ship ballast
• For erecting floating bridge or pipeline

Key Features of Roller Airbags for Ship Launching

1. Flexible in various launching projects: Roller airbags can be made to be specified sizes and layers as per the requirement of different launching projects.

2. Easy Operation: The operation of launching vessels with rubber roller airbags is releatively easy, just laying out and inflating the airbags to lift the vessels and roll them to the water.

It has not strict requirement on slipway conditions. Ship launching can be executed even in tough conditions.

3. Durable and recycled: Marine Roller Airbags can be used many times repeatedly.

4. High economy: As marine roller airbags can be used repeatedly and its cost is not high, launching or docking ships with marine roller airbags can save much cost for shipyards or ship owners.

These cylindrical-shaped rubber inflatable is the product of precise engineering that witnesses high grade flexible rubber material undergo innovative layering manufacturing and extremely strict quality control compliances.

Standard  ship launching airbags have sizes up to 2.5m in diameter and 25m in length for hoisting and transporting heavy structure up to more than 10,000 tonnes. However, some airbags for buoyancy purposes can go up to 4.0m in diameter.

The product is also widely used for mobilisation of various large scale prefabricated steel concrete, gas drilling equipments, architectures and caissons etc.

Application status of air bag launching

After more than 40 years of practice and improvement, the airbag launching technology has become increasingly mature. With the rise of tidal flat shipbuilding in various countries, the promotion and development of marine airbag launching technology has been promoted. Because it does not require a regular site, the beaches on the seashore and the silted land on the river bank can be used. Its flexibility not only compensates for the unevenness of the site, but also has a large contact area that makes the bottom of the ship evenly pressured.

The airbag launching technology provides a broad prospect for the technological transformation and development of small and medium-sized shipyards around the world due to its remarkable advantages such as labor saving, time saving, investment saving, maneuverability and flexibility, safety and reliability. The “Medium and Long-term Development Plan for the Shipbuilding Industry” adopted in August 2006 has included the launching of ship airbags into the scope of basic requirements. It is stipulated that ships produced by enterprises of all levels and types of Class II and Class I and below are allowed to use airbag launching methods. The second-class and first-class ship production enterprises are allowed to produce ships up to 180m in length. The promulgation of this plan provides an opportunity for the development of the airbag launching process. Ship airbag launching technology not only promotes the progress of my country’s shipbuilding industry, but also attracts more and more attention and use of foreign shipyards.
