Innovator of Ship Launching Marine Air Bags
Buoder is professional manufacturer of ship launching marine air bags used for the ship launching and landing, marine salvage and heavy lifting and and contractor of ship launching projects.
We make high quality ship launching marine air bags for ship launching by innovative Holistic Wrapping Technology. All marine airbags for ship launching are manufactured and tested comply with ISO14409 "Ships and marine technology - ship launching marine air bags".
Marine air bags for ship launching, also known as roller bags or ship launching balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Marine air bags for ship launching can be used for the ship launching, ship landing work.
Ship launching relying on ship launching marine air bags 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.
Material of Marine Air Bags for Ship Launching
Ship launching marine air bags 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 air bags 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 marine air bags for ship launching 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 marine air bags for ship launching. 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 air bag production, the out and inner rubber layers are tested to meet the requirements of below table.
Classification of Marine Air Bags for Ship Launching
Ship launching marine air bags 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 airbags — the air bag with 3, 4 or 5 layers of cord fabric
- QG High-bearing capacity airbags — the air bag with 6, 7 or 8 layers of cord fabric
- QS Super-high-bearing capacity airbags — the air bag with 9, 10 or more layers of cord
The standard diameter of ship launching marine air bags (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 marine air bags for ship launching also can be supplied upon request.
Performance Parameters of Marine Air Bags for Ship Launching
Acceptance Test for Commercial Ship Launching Marine Air Bags
Prior to delivery of the marine air bags for 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 air bags for 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.
All Buoder ship launching marine air bags are manufactured and tested comply with ISO 14409 “Ships and marine technology – ship launching air bags 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 Air bags (Shipbuilding Industry Standard, PRC)
— CB/T 3795-1996 / CB/T 3795-2009 Marine 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 air bags
