Are you worried about safely launching your ship? Are you afraid something might go wrong, like airbag leaks or not enough lifting capacity? This can be a big risk for your ship. But you can avoid these problems. That’s why you need to know what to consider when you buy marine airbags. This way, you can make sure your ship’s launch is safe and smooth.
What Are Marine Airbags?
Marine airbags are a new and innovative product made in China. They are widely used for launching ships, heavy lifting, and salvage operations. Marine airbags do not need much space, which makes them a flexible, green, and safe choice.

What Should You Consider When Purchasing Marine Airbags?
When you buy marine airbags, there are many things you need to think about. This helps make sure you choose the right airbags for your ship.
1️⃣ Loading Capacity
Consider your ship’s total weight and the load each airbag can carry. This helps you know how many airbags you need.
2️⃣ Air Pressure
Check the air pressure before and after lifting. Make sure it is not higher than the maximum pressure that the manufacturer allows. This prevents damage to the airbags.
3️⃣ Deformed Height under Load
Consider the deformed height of the airbag under heavy load. This is important for removing blocks under your ship and for making sure your ship floats safely, especially when the stern enters the water first.
4️⃣ Other Factors
Consider your ship’s length, total weight, and the conditions at your launch site. All these details affect the number and size of airbags you need.
