Buoder is professional manufacturer of marine ship launching airbags used for the ship launching, marine salvage and heavy lifting and and contractor of ship launching projects.

We make high quality ship launching airbags by innovative Holistic Wrapping Technology. All ship launching marine airbags are manufactured and tested comply with ISO14409 "Ships and marine technology - ship launching airbags".

Ship Launching Airbags, also known as roller bags, marine airbags, ship launching balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Ship launching airbags can be used for the ship launching, ship landing work.

Ship launching relying on marine ship launching airbags is a innovative ship launching technology, comparing with “end-on launching”, “side ship launching”, “float-out”. This ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more more shipyard world wide because of its advantages of saving time, saving investment, flexible, safety. The biggest vessel launched by ship launching airbags up to 100,000 DWT.

 The Plant of Ship Launching Airbags Production

Material of Ship Launching Airbags

Ship launching airbags 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.

• 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 Ship Launching Airbags

Marine ship launching airbags 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 marine 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 Ship Launching Airbags

Acceptance Test for Commercial Ship Launching Airbags

Prior to delivery of the ship launching airbags, 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 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 ship launching airbags 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.

All Buoder ship launching airbags are manufactured and tested comply with  ISO 14409 “Ships and marine technology – ship launching airbags certificated by CCS, LR, DNV. There are two more China industrial standards and one ISO standard for ship launching airbags:

– CB/T 3837-1998 Technological Requirements for ship Upgrading or Launching Relying on Ship Launching Airbags (Shipbuilding Industry Standard, PRC)
— CB/T 3795-1996 / CB/T 3795-2009 Air bag for ship up to or down to launching way (Shipbuilding Industry Standard, PRC)
–- ISO 17682 Ship sand marine technology —Methodology for launching ship utilizing ship launching airbags

Buoder is professional manufacturer of marine ship launching airbags, ship landing airbags, marine salvage airbags, marine rubber fenders, offshore foam buoys, surface foam buoys, and subsea foam buoys. 

Look forward to our cooperation.
