Marine Salvage Airbags Various Application
Beyond emergency salvage, these airbags are widely used in offshore construction, pipeline installation, and underwater archaeology. For example, in shipwreck recovery, multiple airbags are strategically positioned and inflated in stages to distribute lifting force evenly, minimizing structural stress. Similarly, offshore industries rely on them to deploy or retrieve heavy equipment, such as subsea manifolds or drilling components.
