Product Description
Air Lifting Bags High Buoyancy Easy Deployment Long Service Life
Cylindrical Underwater Air Lifting Bags are flexible pneumatic buoyancy devices engineered for controlled underwater lifting, vessel salvage, refloating operations, temporary flotation, submerged equipment recovery, and marine construction support. The cylindrical configuration provides an elongated buoyant body that can be installed beneath suitable sections of a vessel or underwater structure, allowing buoyancy to be distributed over a defined contact area rather than concentrated at a single lifting location.
Case Study: Underwater Recovery of a 260 Tonne Coastal Cargo Vessel
A marine salvage contractor in Southeast Asia successfully recovered a 260 tonne coastal cargo vessel using multiple cylindrical underwater lifting bags. The vessel was resting at an uneven angle on a muddy seabed with restricted access for large crane vessels. The distributed buoyancy arrangement allowed progressive refloating without creating excessive local loading, demonstrating the engineering benefit of pneumatic buoyancy in restricted marine environments.

Key Features
  • High Strength Multilayer Reinforcement System
    Synthetic tire cord fabric embedded between rubber layers creates a composite flexible structure that maintains dimensional stability under internal pressure and provides excellent fatigue resistance.
  • Optimized Cylindrical Load Distribution
    The elongated buoyancy surface supports load over defined hull sections, allowing progressive inflation and independent control of multiple lifting elements for improved operational flexibility.
  • Abrasion Resistant Marine Rubber Construction
    Engineered rubber compounds provide protection against marine exposure and mechanical contact while maintaining flexibility for repeated deployment.
  • Controlled Buoyancy and Operational Pressure Management
    Progressive inflation allows operators to adjust buoyancy during recovery sequences, providing reversible operating capability and enhanced control over vessel movement.
Applications
  • Marine Salvage and Vessel Refloating
  • Submerged Equipment Recovery
  • Marine Construction and Temporary Buoyancy

Frequently Asked Questions
  • What materials are used to manufacture Cylindrical Underwater Air Lifting Bags?
    The main body consists of reinforced synthetic tire cord fabric combined with engineered rubber compounds for tensile strength, dimensional stability, and environmental protection.
  • Can the lifting bags be used repeatedly?
    Yes, the bags are designed as reusable pneumatic equipment when operated within specified pressure and load limits, with proper cleaning, inspection, and maintenance between uses.
  • How should the bags be protected from underwater obstacles?
    Installation areas should be inspected and cleared of sharp objects. Additional protective padding or barriers should be used when direct contact with hazards cannot be avoided.
  • What information is required for selecting the correct lifting bag configuration?
    Typical engineering information includes vessel weight, hull dimensions, center of gravity, available clearance, water depth, seabed condition, and required reserve buoyancy.
  • Can different diameters and lengths be manufactured for specific projects?
    Yes, cylindrical lifting bags can be configured with different diameters, lengths, and accessory arrangements according to project-specific technical requirements.
