20t Marine Air Lift Bag High Strength Easy To Repair Safe For Salvage Work

Description

The Marine Air Lift Bags from Hongruntong Marine are versatile, heavy-duty buoyancy solutions designed for port construction, underwater maintenance, and professional diving operations. Built with multi-layer thermoplastic fabric and reinforced seams, these underwater air lift bags provide exceptional lifting power while remaining flexible and reliable under challenging marine conditions.

The modular design allows multiple bags to be linked together to achieve higher buoyancy, making them suitable for lifting large prefabricated components, sunken vessels, or heavy equipment. Stainless steel fittings and over-pressure relief valves ensure secure attachment points and safe operation during inflation.

Each bag is engineered for precise buoyancy control, maintaining stability even in dynamic port environments with tidal fluctuations and strong currents. Their foldable and lightweight construction ensures easy transportation, rapid deployment, and repeated use, making them ideal for repetitive port construction tasks, fender installation, and diver-assisted salvage operations.

Designed for capacities ranging from 1 ton to 50 tons, Hongruntong Marine’s air lift bags meet the requirements of commercial harbors, private ports, and offshore docks. Compatible with standard diving air systems and compressors, they offer both safety and operational efficiency for underwater engineers, port contractors, and professional diving teams.

Case Study — Port Fender Installation, Rotterdam

In 2022, a Dutch marine construction contractor faced the task of installing new floating fenders at Rotterdam Port. Each fender panel weighed over 2 tons and required precise underwater positioning to align with existing mooring structures. Conventional lifting equipment proved cumbersome and slow, risking operational delays.

Hongruntong Marine supplied six 8-ton Marine Air Lift Bags, strategically placed under the fender panels. Divers connected the lift bags using stainless steel shackles and reinforced straps. The integrated multi-valve inflation system allowed the operators to adjust buoyancy gradually, achieving millimeter-level control over fender placement.

During the operation, tidal currents and minor underwater obstructions posed challenges. The reinforced seams and durable thermoplastic fabric ensured the lift bags remained stable and intact, while the modular design allowed multiple bags to work in unison for oversized panels. Within two days, all fenders were installed successfully, with no damage or delays.

The contractor highlighted the air lift bags’ efficiency, stability, and reusability, noting that they significantly reduced labor intensity and enhanced operational safety compared to traditional lifting methods. The project demonstrated the effectiveness of Hongruntong Marine’s air lift bags in precise port construction and diving-assisted operations.
