If you own ships or run a shipyard, this is for you. Marine rubber airbags (sometimes people type “ship aunching airbags” — that’s a typo for подушки безопасности для запуска кораблей) give you a cheap, flexible, and safe way to launch, haul out, or move vessels. Below I explain how they work, why they save money and time, and what to check when you buy. I keep the language plain and the points short — so you can act fast.
How marine airbags work
You put long, strong rubber airbags under the hull, inflate them, and the ship rides on a set of rolling airbags into the water. The bags carry the hull, reduce point loads and friction, and let the ship roll smoothly off the ramp. This method replaces heavy fixed slipways or expensive dry docks in many cases.
Why shipowners and shipyards pick airbags
1. Big savings vs building slipways
You don’t need large, permanent steel or concrete slipways. That cuts capital cost and maintenance. For many yards, marine rubberairbags deliver the same result with far less investment.
2. Faster work and less labor
Marine rubber airbags are lighter to move, faster to position, and reusable. You can set them up and start the launch in hours rather than days or weeks. That lowers labor and shortens schedules.
3. Portable and flexible
Bring airbags to remote sites, beach launches, or yards without full infrastructure. They adapt to different ramps, water levels, and ship sizes — which means more project options for your yard.
4. Gentle on the hull
Rubber airbags cushion the hull and reduce local stress and scraping compared with raw block-and-roller methods. Properly used, they lower repair risk during launch.
5. Proven and scaled
Airbag launching is a mature method with standards and many real projects. They now handle small boats up to very large ships when planned correctly.
Real numbers & buying sense
- You will see a wide price range depending on bag size, layer count, and certification. Market listings show single-bag prices from low hundreds to several thousands USD; bundles for big ships run higher. Use price listings only as a guide — get quotes for exact specs.
- Look for bags made to ISO rules and tested for pressure/air tightness. That lowers risk and helps with Class approvals.
Quick buyer checklist
- Match size to your ship. Bag diameter, length and layer count matter.
- Ask for ISO 14409 / ISO 17682 compliance. These cover manufacture and launching method.
- Inspect test records. Look for air tightness and burst tests.
- Plan the ramp and tow system. Airbags need a reasonable slope and strong anchors.
- Get operator training. A good supplier will help with on-site guidance.
FAQ (short & useful)
Q: Are airbags safe?
A: Yes, when you use certified bags, follow ISO guidance, and plan the ramp and tow system. Treat safety like any heavy-lift job.
Q: How many bags do I need?
A: That depends on ship weight, hull shape, and bag size. Suppliers calculate the number and layout (linear, staggered, two-line). Ask the supplier for a layout plan.
Q: How long do airbags last?
A: With good care and storage they last many seasons. Life depends on usage, load, and maintenance. Check manufacturer warranties and inspection intervals.
Q: Can airbags replace a dry dock?
A: For launching and many haul-out tasks, yes — especially for small and medium ships or yards that need flexible options. For full maintenance that needs dry-dock services (deep underwater work), you may still need a dock.
Short close — why act
If you want a lower-cost way to launch, move, or haul boats without building fixed gear, marine airbags are a strong, proven choice. They free your schedule, cut capital spend, and work at many sites.
