Marine Salvage Airbags (balloons)
The salvage tubes are similar to enclosed-type lift bags while they are much stronger. They have evolved from ship launching airbags and have multi-plies reinforcement layers made of rubber and synthetic-tire-cords. The thickness of tube body exceeds 6 mm often. Salvage balloons are extensively used for jack up stranded vessel and lifting sunk ship.
