Inflatable Buoyancy Bags Flexible High Strength UV Resistant Compact Portable Design
Description
Marine Salvage Airbags are highly versatile underwater lifting tools widely used in modern marine operations. They are made from high-strength composite materials, providing excellent resistance to corrosion, abrasion, and water pressure. These airbags allow safe and controlled lifting of submerged objects, from sunken vessels to heavy machinery, in both deep-sea and port environments. Inflation generates precise buoyancy, enabling divers or ROVs to raise objects steadily to the surface, reducing operational risks.
Case Study: Sunken Fishing Vessel Recovery in Singapore Port
In early 2024, a 12-ton fishing vessel sank near Singapore’s commercial harbor due to unexpected hull damage. The local marine rescue team deployed our Marine Salvage Airbags to recover the vessel. After an initial survey using a diver team and sonar imaging, the team determined optimal placement points for three medium-sized airbags.
The airbags were secured around the hull, emphasizing key load-bearing sections to avoid deformation. Gradual inflation using compressed air ensured a controlled lift, keeping the vessel stable even under tidal currents. Over the course of 5 hours, the fishing vessel rose to the surface without secondary damage.
The operation demonstrated Marine Salvage Airbags’ superior reliability under moderate currents and shallow-to-midwater depths. The rescue was completed 30% faster than conventional crane-assisted lifting, highlighting both time efficiency and enhanced diver safety. This successful operation underlines the airbags’ adaptability for small-to-medium commercial vessel recovery in busy port areas.

Features
High Performance Composite Construction
Marine Salvage Airbags are crafted from multi-layer polyester fibers reinforced with PVC, forming a robust outer layer resistant to abrasion and punctures, and a water-tight inner bladder. This ensures the airbags maintain structural integrity under maximum buoyancy loads while resisting saltwater corrosion, oil, and other contaminants typical in port and ocean environments.
Precision Buoyancy Control
Multiple inflation ports with high-accuracy valves allow gradual and adjustable buoyancy, enabling precise lifting of objects with irregular shapes. Single or multi-point inflation ensures balance and prevents tilting or rolling during ascent. Multiple airbags can be used in combination for larger or unevenly weighted objects, providing flexible and safe lifting options.
Rapid Deployment and Securing
Lightweight and compact, Marine Salvage Airbags are easy for divers to transport and deploy underwater. Integrated attachment loops and reinforced straps allow quick positioning at critical points. Even in strong currents or limited visibility, installation and removal can be performed efficiently, minimizing diver exposure time and maximizing operational safety.
Redundant Safety Systems
Marine Salvage Airbags incorporate dual-layer bladders, pressure relief valves, and monitoring ports, ensuring continued operation even if one layer is damaged. Surface monitoring allows operators to track buoyancy changes in real-time, preventing accidents and providing high safety assurance during critical lifting operations.
Applications
Commercial Vessel Recovery
Ideal for sunken or partially submerged commercial vessels such as fishing boats, cargo ships, and tugboats, Marine Salvage Airbags can lift vessels safely in active port areas without interfering with regular harbor traffic.
Shipyard and Dockside Maintenance
In shipyards or dry docks, these airbags can assist in hull inspection, machinery installation, or localized underwater repairs. Their flexibility and controlled buoyancy make them ideal for lifting specific sections of large ships or supporting heavy underwater equipment.
Oceanographic and Offshore Operations
Marine Salvage Airbags are effective for retrieving deep-sea equipment, research instruments, or samples during oceanographic surveys. Their precise inflation and robust construction ensure safe recovery of sensitive payloads under varying depth and pressure conditions.
