Ship Launching Airbags are heavy-duty marine engineering components designed for vessel launching, landing, and controlled translational movement in shipyard and offshore construction environments. Constructed from multi-layer reinforced synthetic tire cord fabric combined with high-strength vulcanized rubber compounds, these cylindrical flexible pressure-bearing structures provide controlled elastic deformation under internal pneumatic loading.
A coastal shipbuilding facility in Hai Phong, Vietnam successfully launched a 2,900-ton general cargo vessel using Ship Launching Airbags in a constrained industrial zone without dry dock infrastructure. The system demonstrated improved load stability, reduced friction resistance, and controlled transition dynamics during the launching process.

* Other sizes can be produced following client's requirements.
The load capacity depends on airbag diameter, reinforcement layer configuration, and system deployment quantity. The system is engineered for scalable application across a wide range of vessel tonnage when properly configured.
Service life is determined by usage frequency, environmental exposure, and maintenance practices. Under standard industrial operating conditions with proper maintenance, the system supports multiple repeated operational cycles.
Pressure is managed using industrial air compression systems equipped with calibrated monitoring instruments. Inflation is performed in controlled stages to ensure stable pressure distribution and structural balance.
The system is engineered for coastal, offshore, and industrial marine environments. It maintains structural performance under humidity, saline exposure, and variable ground conditions commonly found in shipyard operations.
Yes. The structural design supports repeated inflation and deflation cycles. With proper inspection and maintenance, the system maintains stable mechanical performance across multiple launching operations.
