Ship Landing Launching Marine Lifting Airbag Diameter 1.5m
Marine airbags have proven to be highly effective and versatile tools in numerous marine projects. These include ship disembarkation, heavy transportation, and re - floating salvage operations, among others. However, the question of how to choose the appropriate marine airbags for a particular project remains crucial. Let's take a look at the suggestions put forward by a professional marine airbags manufacturer and engineering company.
Today, marine airbags are extensively utilized in ship launching, heavy transportation within the marine environment, and marine salvage efforts. They are commonly referred to as ship launching airbags, which highlights that one of the most common applications of these heavy - duty airbags is in the ship launching process. It is estimated that over 80% of newly built ships with a Deadweight Tonnage (DWT) of less than 60,000 are launched using marine airbags.

When selecting an airbag, ensure that its effective length is not less than the maximum width of the vessel or any object you intend to move using the airbags. When arranging two rows of airbags, be sure to calculate the total length to prevent contact between the airbags in the two rows. The total length of an airbag can be approximated as the sum of its effective length and diameter. For instance, if an airbag has an effective length of 16 meters and a diameter of 1.5 meters, its total length would be 17.5 meters.
The diameter of the airbag is determined by the height of the support blocks of your vessel. If the support block is 1 meter high, you should choose an airbag with a diameter of at least 1.5 meters. If the support block is 1.5 meters high, an airbag with a 2 - meter diameter would be a good fit.
In the case of air lift applications, the diameter or length of the airbag is primarily determined by the buoyancy required. Additionally, when using airbags in deep water, the pressure the airbag can withstand must also be taken into consideration.
For the transportation of caissons using marine airbags, the most appropriate diameter ranges from 0.8 to 1 meter. The performance of a marine airbag depends on the number of component plies. For air lift operations or launching light vessels (with a launch weight of less than 2000 tons), mid - pressure airbags are sufficient. For heavy - duty tasks, high - pressure airbags should be selected. Generally, airbags with 6 plies are adequate for most engineering projects. Only under certain demanding circumstances, such as when lifting heavy caissons with a limited contact area, will airbags require 7 - 8 plies to enhance their 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 offer the basic calculation of marine airbags employed in a marine project.
According to Chinese industrial standards people will know the approximate quantity and specifications of marine airbags needed for their projects then consult the manufacturer to confirm the design. There maybe optional specifications to be selected for a specific marine project and a good manufacturer should know the best choice. The data of marine airbags' blasting pressure will reveal the product's quality level. For top quality marine airbags, such as one 1.5 m diameter and 7 m length Evergreen marine airbag, the blasting pressure is 0.67 Mpa which indicates the safe coefficient is more than 5 considering its 0.12Mpa working pressure.
Full technical service is the qualification of a good company. Although general calculation formula or performance data of marine airbags can be got from most factories but detailed calculations based on mathematic model and experience is more important to the success of marine projects.
In a word
Good selection of marine airbags is vital for the success of marine projects. Get basic knowledge of marine airbags selection then consult with manufacturers can help people complete projects in shortest time.
