What Are Marine Airbags?

 

Our Inflatable Marine Airbags feature an innovative inflatable design that enables effortless inflation and deflation. Their remarkable versatility makes them the go - to choice for a range of marine operations. Shaped cylindrically, these airbags are engineered to function optimally within a pressure range of 0.2 - 0.4 Mpa, ensuring both safety and stability during use. This design also allows them to support vessels of various sizes effectively.

Applications of Marine Airbags

 

Ship Launching: One of the primary uses of marine airbags is in ship launching. The process begins with laying uninflated cylindrical airbags beneath the boat. As they are inflated, the boat is lifted, allowing for the removal of any obstacles underneath. Subsequently, air is released from some of the rear airbags, and the boat is gently pushed to initiate the launch. Ship launching in the shipbuilding industry is a complex affair. While large shipyards often rely on rail - sliding methods, which require a slipway or dock and entail high costs, marine airbags offer a more accessible alternative. Small and medium - sized shipyards, in particular, favor airbags due to their low investment requirements and wide - ranging applications. In fact, more than 80% of new ships under 60,000 DWT are launched using marine airbags. The flexibility of airbag - assisted launching is a major advantage; any flat ground with a slight slope can serve as a slipway, and ships can even be launched from banks 1 or 2 meters above the water level.

Docking and Undocking: Marine airbags also play a crucial role in the docking and undocking processes of ships. They provide the necessary support, ensuring smooth and safe maneuvering of vessels in and out of ports.

Material and Structure of Marine Airbags

 

Outer and Inner Rubber Layers: The Luhang marine airbag for ship launching is constructed with a sophisticated design comprising five functional rubber membranes. The outer rubber layer is of utmost importance as it shields the underlying layers from abrasion and external forces. It is engineered to have sufficient tensile and tearing strength, ensuring the airbag's durability during harsh marine operations.

Synthetic - Tire - Cord Reinforcement Layers: To reinforce the airbag and enable it to withstand high internal pressures, synthetic - tire - cord layers are incorporated. These layers are arranged at precisely calculated angles. Their strategic placement allows them to evenly distribute stress and hold the internal pressure, significantly enhancing the airbag's overall strength.

End Fittings: The airbag is equipped with essential end fittings, including an air - tightness swivel and a safety air inlet. The cylindrical body of the airbag is complemented by two conical heads, which are fitted with metal bushings and plugs for seamless air inflation. The entire airbag is manufactured using a patented whole - enlacing technology, resulting in a structure with no joints on the cylindrical body and hemispherical heads, further enhancing its integrity.

Reasons to Choose Our Marine Airbags

 

Manufacturer's Expertise: With over 20 years of experience in the industry, we stand as a leading professional manufacturer of marine airbags. Our team consists of highly skilled workers who utilize mature technology and adhere to strict quality control measures. This ensures that our airbags are of the highest quality, with a particular emphasis on air - tightness.

Product Quality and Certifications: We use optimized rubber materials to manufacture our marine airbags, which are available in a variety of sizes and layer configurations. Our products are ISO - certified and hold numerous product patents. Additionally, they have been inspected and approved by renowned third - party organizations such as BV, SGS, and V - Trust. These airbags exhibit excellent high - pressure and air - tightness performance, making them a reliable choice for marine operations.

Size and Performance Considerations

 

Effective Length: The ideal effective length of a ship - launching airbag should be equal to the ship's breadth or 1 meter shorter. We have the capability to produce airbags with lengths ranging from 5m to 24m.

Diameter: The diameter of the airbag is selected based on the size of the ship and the specific work requirements. Larger ships necessitate bigger airbags, while smaller boats can make do with smaller diameters. For tasks such as ship bottom cleaning or repair, larger - diameter airbags offer more comfort for workers. Diameters of 1.5m, 1.8m, 2m, or 2.5m are commonly used for large ships.

Number of Layers: The number of layers in an airbag directly correlates with its bearing capacity. Generally, 6 - layer airbags are sufficient for most projects. However, in more demanding scenarios, such as when lifting heavy caissons with a limited contact area, 7 - 8 layers may be required. These additional layers enable the airbag to withstand higher pressures, ensuring safety and successful operation.

 

When planning a marine project involving the use of airbags, it is crucial to select the appropriate size and number of layers. If you are unsure about the suitable specifications for your ship - launching or docking project, please do not hesitate to contact us. We require the following information to assist you:

 

Ship size, specifically the breadth (width) and length.

Ship weight (it is preferable to provide the weight of the vessel without cargo).

Lifting height, which is the maximum height you intend to lift the ship from the ground.

The slipway condition, including the slope angle and the ground surface characteristics.
