Flexitank inflatable lift bags provide a vast range of technical and commercial advantages:

  • Optimised to transport and to stow: around 500t of buoyancy can fit into a 20ft container; an incredible 1000t of buoyancy can be shipped in a single 40ft container;
  • Can be taken subsea deflated, and only inflated to provide buoyancy as and when required;
  • Operational flexibility via remote, user-controlled, variation of total buoyancy;
  • Easy to handle: mass to buoyancy ratio of approximately 1%, so a 5t enclosed lift weighs only 45kg (99lbs); and,
  • Low ongoing maintenance requirements and very easily repairable if the need ever arises
