Specifically designed for use where water depth is a critical factor.

The totally-enclosed, cylindrically-shaped bags are perfect for shallow water salvage, reducing the draft of a vessel, or raising an object closer to the surface. Salvage Pontoons also prove invaluable in cable and pipeline operations, or where long tows are planned.

Available in both standard cylinder shape and elongated tubes.

Constructed of heavy-duty, ballistic-rated nylon fabric coated with urethane. This specially-coated fabric is:

  • High strength
  • Very resistant to abrasion
  • Not affected by most petro-chemicals
  • UV resistant

The pontoon design incorporates a replaceable, heavy-duty nylon webbing lift harness built into the body of the lift bag, and has a safe working ratio of 6:1.

The harness arrangement maintains the lift bag in a horizontal position while insuring maximum stability.

CAUTION: Salvage Pontoons have multiple attachment points. All attachment points must be connected with the shackles provided, and the load evenly distributed. Large pontoons require a separate lifting beam to evenly distribute the load.

SUBSALVE USA Salvage Pontoons are equipped with:

  • 3/4" NPT inflation port
  • Equipped with brass quick disconnect for inflation
  • 3/4" NPT bronze ball valve for deflating
  • Pressure relief valves – they are set to release at 2.5 psi above ambient pressure
