Summary

Marine salvage and refloatation is another application of ship launching marine airbags after update. Teamwork Maritime marine salvage airbags are designed with lifting belts and shackles equipped on the update ship launching air bags.

Application

Marine Salvage Airbags is the toughest air lifting bags. It can be used as salvage pontoon for the supporting docks, and other floating structures. Also can be used to salvage the shipwreck, rescue the floating bridge and dock construction. It really come into own when marine salvage airbags employed in heavy duty salvage work under severe environment.

Working principle

Through inflating the compressed air to produce buoyancy, then using buoyancy to salvage. It is easy to operate and safe and reliable. In addition to hang a ship in a fixed position or connected with lifting jack of the bottom of ship, ship airbag also can be placed inside the ship cabin, through filling out the cabin water to provide buoyancy.

Construction Features of Marine Salvage Airbags

Marine salvage airbags is to be constructed of an out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. It has the cylindrical balloon body, with two conical head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth.

Construction of Marine Salvage Airbags

Polyester webbing lifting straps are located symmetrically along the body of marine salvage airbags. The pick points of every strap are then connect to one screw pin shackle. The total lifting of these straps shall maintain a minimum 6:1 safety factor of the operational load.

Buoyancy List of Marine Salvage Airbags

Different combination of diameter and length, make marine salvage airbags achieve different buoyancy capacity. The biggest buoyancy of each marine salvage airbag can reach 100ton.
