How to Choose the Right Marine Salvage Airbags for Your Project

When you’re faced with a stranded or sunken ship, choosing the right marine salvage airbags can make a huge difference. A poor choice could lead to further damage, lengthy delays, or even additional safety risks. So, how do you make the right decision?

Why Is This Issue So Important?

Salvaging a stranded or sunken ship is a complex, high-risk, and time-sensitive operation. Often, heavy equipment, huge cranes, or extensive resources are needed, adding significantly to the cost.
Using marine salvage airbags instead can be a game-changer.
They enable a faster, more flexible, and less expensive way to raise or move a stranded or sunken ship safely.
This is why choosing the right airbag for your project is a crucial step toward a successful recovery.

How to Choose the Right Marine Salvage Airbags

➥ Lift Capacity and Size
Consider the depth of water and the weight you need to lift.
Nanhai’s marine salvage airbags come in standard sizes ranging from 50 ton, 100 ton, 200 ton, up to 300 ton — or even custom sizes upon request — making them suitable for deep water operations up to 100 m.

➥ Material Quality and Thickness
Safety is a top priority during a salvage operation.
Nanhai’s airbags are made with high-strength 1400-D3 nylon cord, offering exceptional resistance to puncture and abrasion.
The burst pressure is at least 3 times greater than the rated pressure, adding a safety margin.

➥ Air-tightness
Using a special flexible cylinder forming process, Nanhai’s airbags incorporate a unique rubber air barrier.
This guarantees that air pressure drops by less than 1% within 24 hours — much higher than industry standards — ensuring reliable performance under pressure.

➥ Safe and Reliable Operations
Nanhai’s patented mesh securing technology guarantees ease of use and prevents slippage during lifting.
The mesh locks, shackle links, and specialized design enable smooth, convenient, and reliable operations, especially under challenging conditions.

Getting stranded at sea is a serious and complex challenge.
Using the right marine salvage airbags can enable you to complete the recovery safely, efficiently, and with minimum financial impact.
Instead of wrestling with heavy cranes and extensive equipment, you can let these flexible, strong, and trustworthy airbags do the heavy lifting for you.

People also ask

What size marine salvage airbag should I choose?
It depends on your project’s depth, weight, and lifting requirements. Nanhai’s airbags range from 50 tons to 300 tons, and custom sizes are available.

How much pressure can a ship’s salvage airbag hold?
Nanhai’s marine salvage airbags are designed with a burst pressure more than 3 times their rated pressure, adding a safety margin during operations.

What materials are used in high-load salvage airbags?
These airbags are made from high-strength 1400-D3 nylon cord with exceptional resistance to puncture and abrasion. They also feature a flexible rubber barrier for air-tightness.

Are rubber salvage airbags reusable?
Yes — Nanhai’s rubber salvage airbags are reusable and designed for multiple operations, making them a cost-effective solution for many salvage projects.

How do I calculate lifting capacity for a marine airbag?
Consider your ship’s weight, depth, and lifting point, then select several airbags with sufficient capacity (typically 50 tons, 100 tons, or even up to 300 tons) to raise it safely.
