IMCA Revises Guidance on Underwater Air Lift Bags
The International Marine Contractors Association (IMCA) has revised IMCA D 016 ‘Guidance on open parachute type underwater air lift bags’.
The guidance addresses the initial and periodic examination, testing, certification and maintenance of open parachute-type underwater air lift bags used to lift submerged objects. It also addresses the operational use of these bags and the safety precautions that should be taken during their use. The principle major revisions in this fourth revision are to those sections dealing with the use of inverter lines and hold-back rigging, and to the diagrams in the guidance document.
The new guidance is available for free from the IMCA website.
