Features of Marine Airbags for Ship Launching

Detailed specifications Marine Airbags for Ship Launching

4-layer marine airbags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The marine airbags can safely hold 156-tons with a safe working pressure of 0.08MPa while rolling. When standing still the highest lifting pressure is 0.10MPa while holding 194-tons.

6-layer marine airbags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The air-bags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.
 

The technology of applying pneumatic roller-bags to the launching and landing of ships relieves the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships. Years of trial and error with this technology has increased the ability of launching 100-ton ships to 7,000-ton ships!

Applications of Marine Rubber Airbags

Buoder ship launching marine airbags are also known as inflatable bags,ship launching balloons, roller bags, air lift bags, and salvage bags.Standard air bag maximum diameter size range is 2.0m. High-pressure ship launching marine airbags are used for ship launching, ship landing, ship lifting, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Marine airbags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible and dependable.

Material of Marine Airbags for Ship Launching

Marine airbags for ship launching are to be constructed of an out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. Ship launching airbags are cylindrical balloon body, with two conical head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth. Refer below picture.

• Synthetic-tire-cord layer - Reinforcement layer of the ship launching airbags which are made of rubber coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented “Holistic Wrapping Technology“. To hold the internal pressure and to distribute the stress evenly. Buoder use the 1870 dtex/2 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width, and the breaking strength is more than 310N per cord.
   
• The outer rubber layer covers the outside of ship launching airbags. To protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.

Prior to the ship launching airbag production, the out and inner rubber layers are tested to meet the requirements of below table.

Classification of Marine Airbags for ship launching

Marine airbags for ship launching are categorized by “ordinary airbags”, “high-bearing capacity airbags”, and “Super-high-bearing capacity airbags” according to the bearing capacity.
 

• QP Ordinary ship launching airbags — the ship launching airbags with 3, 4 or 5 layers of cord fabric 
• QG High-bearing capacity ship launching airbags — the ship launching airbags with 6, 7 or 8 layers of cord fabric
• QS Super-high-bearing capacity ship launching airbags — the ship launching airbags with 9, 10 or more layers of cord

The standard diameter of ship launching airbags (D) varies such as 0.8m, 1.0m, 1.2m, 1.5m, 1.8m and 2.0m, etc. The standard effective length of air bag (EL or L) is from 6m to 26m, which should be specified by the user. Other specification ship launching airbags also can be supplied upon request.

Performance Parameters of Marine Airbags for Ship Launching

Acceptance Test for Commercial Marine Airbags Ship Launching

Prior to delivery of the marine airbags ship launching, we test every air bag for the following items:

• The appearance of each ship launching airbag is smooth, glossy and without blemish such as crack, blister, delamination, pits or impurities.
• The length and diameter of each Evergreen Maritime ship launching airbags are measured with the rated working pressure and is within ±3%.
• The gas-tightness is tested without carrying any load as per ISO 14409. The pressure loss is less than 5% of rated working pressure within 1 hour.

Buoder marine airbags ship launching are type approved. This means we have demonstrated the performance of ship launching airbags to independent inspectors CCS. Type approve test is the essential and necessary qualification of qualified manufacturer of ship launching airbags. In addition to the requirements for the material, appearance and dimensional tolerances, “Gas-tightness Test”, “Compression Test”, “Bearing Capacity Test”, “Bursting Test”, and “Compression-recovery Test” are carried out. For more details, please kinldy refer ISO 14409.
