Salvage Airbag

NanHai-Floating salvage airbags are widely used in marine industry of salvage and buoyancy assistance, including rescue of standard ships or sinking ships. The maritime salvage and rescue projects are sudden and time-sensitive, lifting equipment and high costs; if the salvage company adopts conventional lifting methods, it is usually subject to large-scale lifting equipment or high costs. Using salvage airbag is a quicker and more flexible method to implement salvage and rescue working.

    • High safety: Great puncture and abrasion resistance by using 1400-D3 high-strength nylon thread. High safety with bursting pressure being over 3 times of safety factor.
    • Safety valve technology: Safety valve technology is adopted to protect against over-pressure, especially in salvage effectively alleviating the buoy's relative pressure changes when floating from the bottom.
    • Easy & reliable operation: The Floating airbags adopts the net fixation technique - proprietary technology independently invented by Nanhai-Floating Airbag. Net structure lock sleeve and the shackle type link are used to solve the problem of force transmission and prevent the buoy from sliding down.
