Ship launching or upgrading using marine airbags is an innovative ship-launching technology. It overcomes the disadvantage of “end-on launching”, “side ship launching”, and “float-out”. This ship-launching technology overcomes the restrictions of the fixed launching track of side-launch.This flexible ship launching technology is accepted by more shipyards worldwide because of its advantages of saving time, investment, flexibility, and safety. We are constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety, and reliability.
Up to now, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even construction caissons have all been launched using our ship-launching rubber airbags. The biggest vessel launched by ship launching airbags up to 100,000DWT.
Launching air bags Type and Model
Ship Launching airbags are categorized by the following three types according to the bearing capacity, per meter in length. We define the number of layers, which means the number of Synthetic-tyre-cord layers, to confirm the Safety Working Pressure. Other types is available upon clients’ request.
QP - Ordinary airbag - with 3, 4, or 5 cord fabric layers.
QG - high-bearing capacity airbag - with 6, 7, or 8 layers of cord fabric.
QS - Superhigh-bearing capacity airbag - with 9, 10, or more layers of cord fabrics
For example: QG6/1.5x15
QG6: 6 layers of cord fabric + 1 rubber layer
1.5: Diameter is 1.5m
15: Effective length is 15m
Rubber airbags are constructed of an out rubber layer, multi-layer synthetic-tire-cord layers, and inner rubber layer vulcanized firmly. More layers are applied at the end shoulders.
Synthetic-tire-cord layer
Synthetic-tire-cord layer is 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. We use the 1400 dtex/2 or 1400 dtex/3 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width. The breaking strength is more than 310 N per cords.
Inner and Outer Rubber
Prior to the air bag production, the outer and inner rubber layers shall be tested to meet the criteria in accordance with the test methods given in the International Standards listed below. 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.
