Ship Launching Airbags
Reliable Ship Launching Airbags for Safe and Cost-Effective Vessel Launching
Ship launching airbags have become one of the most efficient solutions for launching and landing vessels without the need for permanent slipways or dry docks. They offer excellent flexibility, lower infrastructure investment, and reliable performance for shipyards of all sizes.
NYBON Marine manufactures high-quality ship launching airbags for commercial shipyards, repair facilities and marine engineering projects. Designed for durability and repeated use, our airbags help customers launch vessels safely while reducing construction and operating costs.
What Are Ship Launching Airbags?
Ship-launching airbags, also known as marine rubber airbags or pneumatic launching airbags, are heavy-duty inflatable rubber cylinders used to launch, land, and move vessels.
Instead of relying on fixed slipways(another typical way of launching a ship is to work with slipway winches), the airbags are positioned beneath the hull. As the vessel moves forward, the rolling airbags provide smooth support and controlled movement until the ship enters the water.
Today, airbag launching is widely used for:
-
- Cargo Ships
- Barges
- Fishing Vessels
- Tugboats
- Tankers
- Passenger Ferries
- Floating Structures
Advantages of Ship Launching Airbags
Compared with traditional launching methods, marine airbags provide greater flexibility and lower project costs.Key Benefits
- Lower infrastructure investment
- No permanent slipway required
- Suitable for different vessel sizes
- Easy transportation and installation
- Reusable for multiple projects
- Reduced maintenance costs
- Reliable performance in various site conditions
These advantages make airbag launching an attractive choice for small and medium-sized shipyards as well as temporary marine construction projects.
Typical Applications
Ship Launching
Safely launch newly built vessels into the water.
Ship Landing
Support vessels during maintenance and repair operations.
Vessel Transfer
Move vessels within shipyards without complex lifting equipment.
Heavy Cargo Handling
Assist in moving oversized marine structures and heavy industrial equipment.

Why More Shipyards Are Choosing Airbag Launching
Shipyards today are under increasing pressure to reduce construction costs while maintaining safety and efficiency. Traditional slipways require significant civil engineering work and long construction periods, making them less practical for many projects.
Ship launching airbags provide a flexible alternative. They can be deployed quickly, reused for multiple launches and adapted to different vessel sizes without major infrastructure changes. This allows shipyards to shorten project schedules, lower investment costs and improve operational flexibility.

Just For Your Trust
How to Choose the Right Ship Launching Airbags
Selecting the correct airbag depends on more than vessel weight. Several factors should be evaluated to ensure a safe and efficient launching operation.
Customized Airbag Solutions
Every shipyard has different launching conditions. NYBON Marine provides customized airbag solutions based on:
- Vessel displacement
- Ship dimensions
- Airbag diameter
- Effective length
- Rubber layer quantity
- Working pressure
- Launching site conditions
Our engineering team can also assist in selecting the appropriate number and arrangement of airbags for your project.
Every ship launching airbag is manufactured under strict quality control procedures using premium natural rubber and high-strength synthetic tire cord reinforcement.
Our quality assurance process includes:
- Raw material inspection
- Rubber compound testing
- Tire cord inspection
- Vulcanization control
- Air tightness testing
- Pressure testing
- Final inspection before shipment
Each airbag is tested to ensure reliable performance and long service life in demanding shipyard environments.
Relevant Standards
Our ship launching airbags are manufactured in accordance with ISO 14409, the internationally recognized standard for marine airbags. Products can also be supplied to meet customer-specific technical requirements and project specifications, with third-party inspection available upon request.
Frequently Asked Questions
What is a ship launching airbag?
It is a heavy-duty inflatable rubber airbag used to launch, land and move vessels without a permanent slipway.
What vessel sizes can use airbags?
Ship launching airbags are suitable for small fishing boats, tugboats, barges, cargo vessels and many medium-sized commercial ships. Larger projects can also be supported with customized airbag arrangements.
