Application Fields of Marine Airbags

Why Should You Understand Marine Airbags?

Marine airbags provide a flexible and cost-effective alternative to traditional shipyard equipment.
For example, instead of using steel rails, one shipyard launched a 10,000-ton cargo vessel using airbags. As a result, they reduced their costs by over 30% and saved valuable time.
Clearly, this technology is helping modern shipyards upgrade their operations.

Main Applications of Marine Airbags (Powered by NANHAI)

1. Launching and Hauling Ships

Over the past 20 years, shipyards have used marine airbag to launch and haul vessels safely.
From small flat-bottom boats to large 10,000-ton ships, this method has proven safe and reliable.
Moreover, shipbuilders in the U.S., Europe, and Southeast Asia have adopted this technique, showing its global appeal.
NANHAI offers complete airbag systems with full technical support, making your launch process faster and easier.

2. Moving Heavy Structures

In addition to ship launching, airbags are widely used in port construction.
For instance, they help lift and transport large concrete structures such as caissons and foundations.
A great example is the “Nanhai No.1” shipwreck recovery project, where NANHAI airbags successfully moved a massive underwater structure into the museum’s Crystal Palace.
NANHAI supports large-scale port projects worldwide with safe and efficient airbag systems.

3. Floating and Salvage Operations

Besides lifting, airbags also provide strong buoyancy.
As a result, many salvage teams use them to recover stranded ships or sunken objects.
Their excellent load-bearing capacity makes them a preferred tool for emergency marine operations.
NANHAI delivers fast-response floating and salvage solutions for clients worldwide.

People Also Ask

1. What’s the difference between marine airbags and ship fenders?
Marine airbags are used for launching and lifting, while ship fenders (like marine rubber fenders) are installed on docks or ships to prevent collision damage.

2. Can marine airbags support floating platforms?
Yes, they can help lift, stabilize, or position floating structures during installation.

3. Which marine rubber fenders manufacturers offer high-quality airbags?
NANHAI is a trusted brand with years of export experience and many successful projects worldwide.

4. Do extruded rubber fenders work with airbags?
They often do. Extruded fenders provide surface protection and friction, helping control movement during heavy-lift tasks.

5. How long do NANHAI airbags last?
With regular maintenance, they can work reliably for 6 to 8 years or even longer.
