Product Description
Marine Salvage Airbags

Marine salvage airbags are engineered based on ship launching airbag technology, representing the most robust solution for salvage operations. These specialized airbags serve as floating pontoons for salvage and flotation applications, capable of supporting critical marine operations including shipwreck salvage, floating bridge rescue, and dock construction.

Key Features
  • Constructed with high-tensile outer rubber layer and multiple heavy-duty synthetic-tire-cord layers
  • Vulcanized inner rubber layer for maximum durability
  • Equipped with lifting belts and shackles for secure handling
  • Integrated safety valves for automatic pressure release in deep water applications
  • Cylindrical balloon design with conical heads and airtight swivel connections
  • Polyester webbing lifting straps with 6:1 safety factor buoyancy rating
  • Superior toughness compared to standard PVC underwater air lift bags
Primary Applications

Marine salvage airbags excel in demanding environments where reliable, controllable buoyancy is essential. They are particularly effective for:

  • Pipeline float-out operations
  • Beach pulls and river crossings
  • Vessel and platform draught reduction in shallow waters
  • Temporary bridge and dock pontoons
  • Heavy-duty salvage operations in severe conditions
