Salvage Air Bags High Buoyancy Durable Material Rapid Inflation 

Boat Air Bags are high-performance inflatable buoyancy devices engineered for underwater lifting, marine salvage, subsea installation support, and controlled buoyancy operations. Designed specifically for demanding marine environments, these airbags provide reliable lifting force through controlled air displacement while maintaining structural stability under submerged conditions.

Manufactured from heavy-duty synthetic fabric reinforcement encapsulated within marine-grade rubber compounds, Boat Air Bags combine high tensile strength with excellent flexibility and pressure resistance. The reinforced multi-layer construction ensures resistance to hydrostatic pressure, mechanical stress, and repeated inflation cycles.

A marine contractor operating in a Middle Eastern coastal industrial zone faced the challenge of recovering a partially submerged 3,500-ton construction barge that had taken on water during a severe storm. The barge settled unevenly on a muddy seabed at approximately 18 meters depth, making crane lifting impractical.

Hongruntong Marine supplied a set of heavy-duty Boat Air Bags designed specifically for underwater lifting operations. Engineering assessment included buoyancy calculations, attachment point planning, staged inflation procedures, and diver-assisted installation guidelines.

Controlled air injection allowed gradual buoyancy increase, lifting the barge incrementally from the seabed while maintaining stability. The flexible structure of the airbags adapted to seabed contours and vessel geometry, minimizing shock loading. The barge was successfully refloated without hull deformation or additional structural damage.

Note: Other sizes can be customized according to the requirements.

• High Buoyancy Efficiency and Controlled Lifting Capability: Engineered to deliver predictable buoyancy force through efficient air displacement under water with gradual inflation control for fine-tuned lifting force.
• Reinforced Structural Design: Internal reinforcement system utilizes high-strength synthetic cord fabrics to withstand hydrostatic pressure, tensile stress, and repeated inflation cycles.
• Durable Marine Grade Material: Constructed using specially formulated rubber compounds resistant to saltwater corrosion, microbial degradation, UV exposure, and abrasion.
• Deployment Flexibility and Operational Efficiency: Provides exceptional logistical flexibility with compact transport, diver installation, and progressive on-site inflation.

• Marine Salvage and Vessel Recovery: Refloating grounded or sunken vessels, recovering submerged equipment, and stabilizing damaged marine assets.
• Offshore Construction and Subsea Installation Support: Positioning pipelines, underwater structures, anchors, and marine equipment with temporary buoyancy support.
• Underwater Maintenance and Emergency Response: Temporary flotation, underwater inspection support, and emergency marine response operations.

• What lifting capacity can Boat Air Bags provide underwater?
  Capacity depends on airbag volume, operating depth, and configuration. Engineering calculations are typically performed to determine the required buoyancy for specific lifting tasks.
• Can they be reused after underwater operations?
  Yes. After proper cleaning, inspection, and storage, they can be reused multiple times in salvage, installation, or maintenance projects.
• Are they suitable for deep-water applications?
  They can operate at various depths depending on design specifications. Pressure ratings should always be matched to project depth requirements.
• How are Boat Air Bags installed underwater?
  Installation can be performed by professional divers or remotely operated systems. Attachment methods vary based on lifting objectives and structural conditions.
• Do you provide engineering guidance for lifting projects?
  Yes. Hongruntong Marine offers technical consultation, buoyancy calculations, and operational recommendations to ensure safe and efficient use.
