Parachute Lift Bag High Strength Durable Construction Reliable Underwater Lifting

Hongruntong Marine Parachute Underwater Lift Bag is a professional underwater buoyancy solution specifically engineered for marine salvage, offshore construction, underwater recovery, commercial diving, and subsea installation projects. Featuring an open-bottom parachute design, the lift bag provides controlled buoyancy while automatically balancing internal air pressure during ascent, making underwater lifting operations safer, more stable, and significantly more efficient than traditional lifting methods.

Constructed from premium heavy-duty PVC-coated polyester fabric, the lift bag combines exceptional tensile strength with excellent resistance to abrasion, puncture, seawater corrosion, ultraviolet radiation, and harsh marine environments. High-frequency welded seams create a durable airtight structure capable of maintaining reliable buoyancy throughout prolonged underwater operations. Reinforced load-bearing webbing is integrated throughout the entire bag body, ensuring lifting forces are evenly distributed while reducing structural stress and extending product service life.

Hongruntong Marine manufactures Parachute Underwater Lift Bags in multiple lifting capacities to accommodate a wide range of operational requirements. Customers can select customized buoyancy ratings, inflation valves, overpressure relief valves, lifting harnesses, shackles, color options, and identification markings based on specific project needs.

Case Study: Offshore Pipeline Recovery Project in Southeast Asia

A marine engineering contractor undertaking subsea pipeline maintenance for an offshore gas terminal encountered a major operational challenge when several pipeline support frames weighing approximately six tons each became displaced after strong seasonal currents. Located at a water depth of nearly 28 meters, the steel structures required precise underwater recovery before pipeline repair work could continue.

The contractor initially considered using a floating crane; however, vessel mobilization costs and restricted working space around the offshore platform made this option both expensive and inefficient. After reviewing alternative lifting solutions, the engineering team selected Hongruntong Marine Parachute Underwater Lift Bags.

Commercial divers attached certified lifting slings to each support frame before positioning multiple lift bags to ensure balanced buoyancy. Air was gradually introduced into the bags through the inflation system, allowing the lifting force to increase steadily. Thanks to the open-bottom design, internal air pressure automatically adjusted as the lift bags ascended, preventing uncontrolled expansion while maintaining stable buoyancy throughout the lifting process.

The displaced support frames were successfully lifted from the seabed and transported to a recovery barge without causing additional damage to the surrounding pipeline infrastructure. Compared with the original lifting plan, the underwater lift bag solution reduced equipment mobilization expenses by more than 35% and shortened the project schedule by nearly three days.

The project supervisor praised the stability of the lifting operation, noting that divers experienced improved control throughout the recovery process. The robust construction of the lift bags also demonstrated excellent resistance to repeated deployments in seawater without noticeable wear or performance loss.

Key Features

Open Bottom Design for Automatic Pressure Regulation: The open-bottom structure automatically releases excess air when internal pressure exceeds surrounding water pressure, improving operational safety and reducing diver workload. This self-regulating mechanism minimizes sudden movements and uncontrolled ascent.
Heavy Duty Reinforced Construction for Maximum Durability: Premium PVC-coated polyester fabric provides exceptional tensile strength and resistance to abrasion, seawater corrosion, and harsh marine environments. High-frequency welded seams and reinforced load-bearing webbing ensure long-term reliability.
Excellent Buoyancy Performance for Various Underwater Operations: Provides smooth, stable, and highly controllable buoyancy across a wide range of applications. Optimized shape maintains excellent stability underwater, reducing unwanted rotation or shifting during ascent.
Flexible Customization to Meet Project Requirements: Extensive customization options including lifting capacities, dimensions, inflation systems, overpressure relief valves, lifting harness configurations, color identification, and hardware accessories.

Applications

Marine Salvage and Underwater Recovery: Ideal for recovering sunken vessels, anchors, propellers, engines, containers, construction equipment, and other submerged objects.
Offshore Construction and Subsea Installation: Used during pipeline installation, platform construction, cable laying, subsea foundation positioning, and underwater structural maintenance.
