Marine Rubber Airbag for Ship Launching & Heavy Lifting
High Efficiency • Low Cost • Flexible Operation
Marine airbags are widely used for ship launching, landing, heavy lifting, caisson moving, and salvage engineering. Compared with traditional slipway launching methods, marine airbags require no large-scale infrastructure or heavy launching equipment, significantly reducing project investment and construction time.
Core Advantages
• Lower Construction Cost - No fixed slipway or dry dock required
• Fast Deployment - Easy installation and operation on various sites
• High Flexibility - Suitable for different vessel types and tonnage
• Safe & Reliable - Stable load distribution during launching operation
• Wide Applicability - Effective in limited or temporary working areas

Technical Features

1. Superior Pressure Resistance

Marine airbags are subjected to extremely high compressive loads during ship launching operations. Our airbags are designed with:

• Reinforced synthetic tire-cord layers
• Optimized internal pressure distribution
• High-strength rubber composite structure

This ensures:

• Excellent deformation resistance
• Stable load-bearing performance
• Improved operational safety under uneven stress conditions

2. Enhanced Durability & Environmental Resistance

Designed for harsh marine environments, the airbags provide:

• UV resistance
• Seawater and freshwater resistance
• Abrasion resistance
• Anti-aging performance
• Chemical corrosion resistance

The multi-layer rubber construction extends service life and reduces maintenance costs.

Optimized Structural Engineering

Using Finite Element Analysis (FEA) and pneumatic load simulation technology, the airbag structure is optimized for:

• Uniform stress distribution
• Improved rolling stability
• Higher bearing efficiency
• Reduced risk of local overloading

Each airbag undergoes strict pressure and performance testing before delivery.

Rubber ship airbags launching type:

1. There are three arrangement to arrange air bags when using the boat launching type.

They are:

(1) linear arrangement as show in the photo.

(2) staggered arrangement as show in the photo

(3) two lines arrangement as show in the photo.

As for which arrangement to use, it needs to depend on the ship's width and the length of the air bags.

2.The  linear arrangement means that :If the vessel width is 12m and the airbags effective length is more than 12m, so you can use the linear arrangement.

3. The staggered arrangement means that: If the vessel width is 18m, and your airbags effective length is 12m, so you should use staggered arrangement.

4. The two lines arrangement means that:When the vessel is 24m width, your airbags is 12m length, you should use the two liners arrangement.

FAQ: Marine Airbags Procurement & Technical Guide

1.Q: How to store and maintain marine airbags?

A: For long-term storage, follow these steps:

1) Wash and dry the airbag, then apply talcum powder.

2)Store flat in a dry, cool, and ventilated indoor place.

3) Do not stack or place heavy pressure on the airbags.

Keep away from heat, acids, bases, oils, and organic solvents.

2. Q: What materials are your marine airbags made of?

A: Our products are manufactured using premium natural rubber and high-tensile rubber-dipped nylon cord fabric.

3. Q: What is your standard delivery time?

A: Generally, it takes 30 to 60 days after receiving the advance payment. The exact lead time depends on the product specifications and order quantity.

4. Q: Do you test all goods before delivery?

A: Yes, we conduct 100% strict quality and pressure testing on all products before shipment.

5. Q: What international certificates do you have?

A: Our products are certified by major classification societies, including ISO, BV, DNV, CCS, and IRS.

6. Q: Do you accept OEM/ODM or custom branding?

A: Yes, we provide full OEM and ODM services. We can print your brand logo and custom-design the airbags based on your technical drawings.
