Seamless Integrated Molding Stable Pressure Endurance Foldable Lightweight Ship Launching Balloon Marine Airbag
Ship Launching Balloon is a heavy-duty inflatable marine engineering load transfer system designed for ultra-high displacement vessel launching, shipyard slipway replacement, and controlled hull transportation operations under large-scale industrial conditions.
Manufactured using ultra-high tensile synthetic tire cord reinforcement combined with modified high-density vulcanized rubber compounds, this cylindrical pneumatic structure features enhanced radial stiffness, superior load dispersion capability, and exceptional long-cycle fatigue resistance.
A large coastal shipbuilding facility in China required a launching solution for an 18,500 DWT chemical tanker constructed on a reinforced concrete slipway platform. The existing infrastructure exhibited excessive localized stress concentration during traditional launching operations.
The Ship Launching Balloon system was implemented as a distributed pneumatic load support matrix arranged in a multi-layer staggered configuration beneath the hull structure. Load distribution calculations were conducted based on full-length hull weight segmentation and dynamic center-of-gravity mapping.
During operation, controlled staged inflation progressively transferred load from fixed cradle supports to pneumatic rolling elements. The system maintained stable deformation behavior under high compressive stress while adapting to minor surface irregularities.
Post-launch structural inspection confirmed uniform stress distribution across hull bottom surfaces with no detectable deformation or coating damage. Operational records indicated improved launch stability and reduced slipway surface wear.
