Marine Launching Airbag with Excellent Air Tightness Strong Tensile Force and

The Airbag Launching Ship system is an advanced marine launching technology developed to transfer newly constructed or repaired vessels from land into water through the controlled rolling movement of inflatable marine airbags. As an alternative to conventional slipways, dry docks, and mechanical launching equipment, this method offers greater flexibility for shipyards while reducing dependence on permanent infrastructure.

Hongruntong Marine manufactures marine airbags using high-quality natural rubber combined with multiple layers of high-tensile synthetic tire cord fabric. The reinforced composite structure is designed to withstand high compressive forces, cyclic loading, rolling friction, and continuous deformation encountered during launching operations.

A medium-sized shipbuilding company in Hai Phong, Vietnam, specialized in manufacturing steel oil barges and inland transportation vessels ranging from 1,800 to 4,500 DWT. The shipyard operated near a tidal river where water levels changed significantly, making traditional launching methods difficult to schedule.

Hongruntong Marine supplied a customized marine airbag launching system designed specifically for the customer's operational environment. The first application involved a 4,200 DWT steel oil barge with a broad hull and substantial launching weight. Throughout the operation, the airbags provided stable rolling support while adapting to the vessel's hull geometry.

The launch was completed smoothly despite uneven tidal conditions, with no measurable hull deformation or structural damage. The customer reported shorter preparation time, improved scheduling flexibility, and lower launching costs compared with conventional methods.
