Marine Air Bag High Buoyancy Heavy Duty Corrosion Resistant for Ship Launching and Salvage

Marine Air Bag is a heavy-duty inflatable rubber system designed for large-scale ship launching, vessel transportation, and offshore marine engineering operations. It is manufactured using multi-layer high-tensile synthetic tire cord reinforcement combined with industrial-grade vulcanized rubber, forming a flexible cylindrical structure capable of sustaining extreme compressive and dynamic rolling loads during shipyard operations.

The system is engineered for high-pressure working environments with typical operating pressure ranging from 0.18 MPa to 0.30 MPa depending on vessel tonnage and engineering configuration. This allows the airbag to maintain structural stability while supporting heavy ship hulls during launching and landing processes.

Marine Air Bag operates through a controlled rolling mechanism that significantly reduces friction between hull and ground surface, providing smoother and safer vessel movement compared to traditional steel slipway systems. The outer rubber layer is designed for extreme environmental durability, offering resistance to seawater corrosion, oil contamination, UV radiation, and mechanical abrasion.

A large offshore shipyard in East Asia was commissioned to launch a 9,500 DWT offshore support vessel designed for deep-sea operations. The project presented significant challenges due to the vessel's heavy reinforced hull structure, high displacement weight, and lack of available dry dock capacity.

Hongruntong Marine designed a customized high-load Marine Air Bag system using 1.5m diameter units with 10-layer reinforced construction and enhanced pressure tolerance. A total of 22 airbags were installed under the vessel according to precise engineering load distribution calculations based on hull geometry and structural stress modeling.

During the launching operation, the vessel was gradually transferred from dry land to water using a controlled rolling system with synchronized air pressure regulation across all airbags. Despite the extreme load conditions, the system maintained stable structural performance without deformation, pressure imbalance, or operational failure. The entire launching process was completed within 65 minutes.

Post-operation inspection confirmed zero hull coating damage and no structural stress concentration issues. The shipyard reported a 45 percent reduction in operational cost compared to traditional dry dock launching methods and confirmed the system's reliability for repeated heavy-duty offshore vessel operations.
