DOOWIN underwater air lift bags can be used for subsea small and large salvage operations. Our robust and highly durable marine salvage buoyancy bags have been used for salvage operations of sunken or grounded vessels, surface buoyancy support. DOOWIN air lifting bags buoyancy products are designed and constructed in compliance with IMCA D016 and LEEA guidelines.
Water-weight bags have replaced stackable solid weights and are widely considered to be the most practical and safest load-testing solution in the world.
Proof load testing using water-filled proof load bags offer is one safe and cost-effective loading test way to load test lifting equipment and load-bearing structures. Especially for the loading test of cranes, davits, derricks, winches, and virtually any other lifting equipment or load-bearing structure.
We also designed water-filled proof load bags for the lifeboat, gangway, and platform.

We manufacture various inflatable buoyancy units for different pipe laying, cable float, and hose floats. Mono single-point inflatable mono buoyancy units are drop-tested with a 6:1 safety factor by BV. Inflatable buoyancy bags are manufactured in compliance with IMCA D016.
Our partner Doowin Marine make the foam filled tie-in pipeline floats. Welcome visit their website to get more information.
IMCA D016 is the gudance on Open Parachute Type underwater air lift bags.
The scope of this guidance addresses the safe use of open parachute type underwater air lift bags used to lift or to reduce the weight of submerged objects. It also addresses the operational use of open parachute type underwater air lift bags and the safety precautions that should be taken during their use.
This IMCA D016 does not include guidance on totally enclosed lifting bags or air/gas filled buoyancy tanks. Such items are designed to support loads on or near the surface and so are not‘underwater air lift bags’ – however, any diver intervention on these items must be properly risk assessed.
This guidance does not apply to water-filled bags used as water weights for testing of other equipment.
For our standard shape and type products, we can make the customzied size. For the non-standard products, we can make it as per your drawing or your need.
LEEA 051 is the guidance on design, inspection, and use of water bags as test weights in the offshore industry.
This document outlines good practice of persons who design and manufacture water bags for use as test weights in the offshore and marine industries. It also outlines the measures duty holders who own or operate water bags should take to verify their continued integrity and to address the‘potential energy’hazard that exists when using water bags.The Lifting Equipment Engineers Association acknowledges the support given by the Health and Safety Executive in the production of this Guidance .
The standard supply range for the water-filled weight bags include webbing slings, round slings, shackles, masterlink, filling water hose, pulley and lanyard, discharge water hose, repair kits, and standard plywood package box.
The load cell dynamometer will be supplied upon request.
We have BV Type Certificate for all standard size water weight bags, TUV/NEL Type Certificate for several common size water bags, and CCS Type Certificate for some air lift bags.
We can provide Manufacturer Certificatre free of charge. We also can provide BV/CCS/DNV third party certificate for the produtes ordered.
