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.
