High Buoyancy Salvage Floating Bags With Reinforced PVC Safe Easy Recovery

High Buoyancy Salvage Floating Bags With Reinforced PVC Safe Easy Recovery

Description

Hongruntong Marine Salvage Airbags are high-performance cylindrical underwater lifting bags, designed for ship salvage, port operations, and underwater heavy lifting. Made of PVC Coated Polyester Fabric, these airbags offer excellent strength, abrasion resistance, and corrosion protection, allowing long-term use in seawater, sand, and oil-contaminated environments without deterioration. Their multi-layered construction enhances pressure resistance and airtightness, ensuring stable buoyancy in deep water. With precise inflation and deflation control, these airbags can safely lift and move vessels, sunken ships, or large offshore structures with controlled vertical and tilt adjustments.

Case Study

At a Southeast Asian port, a 5,000-ton bulk carrier ran aground during docking due to operational error, causing severe hull damage. Traditional cranes could not access the shallow area, making conventional salvage impossible. The port salvage team opted to use Hongruntong Marine Salvage Airbags for the rescue operation.

The team calculated the number and size of airbags based on hull weight and water depth, deploying six Φ2.5m × 10m PVC-coated polyester airbags evenly along the damaged sections. By carefully controlling the inflation pressure, the hull was gradually lifted and, during low tide, the vessel was safely moved off the shallow area. The entire salvage operation was completed in 36 hours without secondary damage to the vessel, ensuring the port’s operational continuity.

This case demonstrates the flexibility and safety of Marine Salvage Airbags in shallow and complex water environments, providing a reliable solution for port emergency salvage operations.

Specifications

Features

High Strength, Abrasion Resistant Material
The airbags are made of PVC Coated Polyester Fabric, providing excellent abrasion resistance, corrosion resistance, and UV protection. This material maintains stable buoyancy even after long-term exposure to seawater and sand. The multi-layer reinforcement design prevents punctures and tears, significantly extending service life.

Precise Buoyancy Control
By adjusting the inflation volume and pressure, the airbags allow smooth lifting of vessels or heavy loads. Equipped with safety valves and pressure monitoring systems, they prevent over-inflation and secondary damage, ensuring operation safety.

Multiple Sizes for Flexible Configuration
Available in diameters ranging from Φ0.8m to Φ3.0m, these airbags can be freely combined according to vessel tonnage, weight, and water depth. Flexible configurations make them suitable for both small fishing boats and large bulk carriers or oil tankers.

Easy Transport and Deployment
PVC material allows airbags to be folded and compressed, making them lightweight and easy to transport on rescue vessels or from shore. When combined with inflation pumps and hoses, rapid deployment on site is possible, improving emergency response efficiency.

Applications

Port Salvage and Refloating
The airbags can quickly support grounded or listing vessels in shallow water, allowing controlled lifting and horizontal movement to safely refloat ships.

Underwater Offshore Structure Lifting
Suitable for lifting and relocating pipelines, dock components, floating bridges, and other large offshore structures, avoiding crane limitations in confined areas.

Offshore and Nearshore Emergency Rescue
For fishing boats, bulk carriers, or tankers in offshore emergencies, the airbags provide stable buoyancy at depth, enabling hull tilt adjustment or slow elevation for safe rescue operations.
