Ship Landing Launching Marine Lifting Airbag Diameter 1.5m

Marine airbags have emerged as potent and versatile tools for various marine projects, including ship disembarkation, heavy transportation, and re - floating salvage. However, the challenge lies in choosing the right marine airbags for a given project. Let's explore the suggestions from a professional marine airbags manufacturer and engineering firm.

Currently, marine airbags are commonly employed in ship launching, heavy marine transportation, and salvage operations. They're frequently known as ship launching airbags, suggesting that ship launching is the most prevalent use of these heavy - duty airbags. It's estimated that over 80% of newly built ships with a DWT (Deadweight Tonnage) under 60,000 are launched using marine airbags.

Marine airbag's specifications

When choosing an airbag, ensure its effective length is at least as long as the maximum width of the vessel or the object you plan to move with the airbags. When arranging two rows of airbags, calculate the total length to prevent the airbags in the two rows from touching each other. You can estimate the total length of an airbag by adding its effective length and diameter. For example, if an airbag has an effective length of 16 meters and a diameter of 1.5 meters, its total length is 17.5 meters.

The diameter of the airbag depends on the height of the vessel's support blocks. If the support block is 1 meter high, choose an airbag with a diameter of no less than 1.5 meters. If the support block is 1.5 meters high, an airbag with a 2 - meter diameter is a good choice.

For air lift applications, the diameter or length of the airbag is mainly determined by the required buoyancy. Also, if you use airbags in deep water, consider the pressure the airbag can endure.

When transporting caissons with marine airbags, the most suitable diameter is 0.8 - 1 meter. The performance of a marine airbag is determined by the number of its component plies. For air lift or launching light vessels (launch weight less than 2000 tons), mid - pressure airbags are sufficient. For heavy - duty tasks, select high - pressure airbags. Generally, airbags with 6 plies are adequate for most engineering projects. Only in some demanding situations, such as when lifting heavy caissons with a limited contact area, will airbags need 7 - 8 plies to improve performance and ensure safety.

 
Reference for marine airbag selection
 
There are two industrial standards for marine airbags in China.: one is product standard named "Air bag for ship up to or down to launching way "; another is technology standard named "Technological Requirements for ship Upgrading or Launching Relying on Air-bags"

The latter provides the basic calculations for marine airbags used in a marine project.

Based on Chinese industrial standards, people can determine the approximate quantity and specifications of marine airbags required for their projects. After that, they can consult the manufacturer to finalize the design. For a particular marine project, there may be several optional specifications available, and a reliable manufacturer should be able to suggest the most suitable option. The blasting pressure data of marine airbags can reflect the quality of the product. Take, for example, a top - quality Evergreen marine airbag with a diameter of 1.5 m and a length of 7 m. Its blasting pressure is 0.67 Mpa. Given its working pressure of 0.12 Mpa, this shows that the safety coefficient is over 5.

A good company should offer comprehensive technical services. While most factories can provide general calculation formulas and performance data for marine airbags, detailed calculations based on mathematical models and practical experience are of greater significance for the success of marine projects.

In conclusion, making a proper selection of marine airbags is crucial for the success of marine projects. Gaining a basic understanding of marine airbag selection and then consulting manufacturers can assist people in completing projects in the shortest possible time.
