ENGINEERING: Water Bag Process For Load Testing


Recent Western Cape Business News

ANCHOR Testing & Rigging Services (ATRS) is now fully operational since acquiring their water bags for proof load testing. The Cape Town-based organisation specialising in testing and rigging services for the engineering, marine and offshore lifting and rigging industries, has made a R2 million investment in water bags, enabling them to facilitate projects for local and global clients.

As opposed to using traditional solid test weights, clients have the option to coordinate tests using water bags. Its innovative design allows for a simplified testing method with the significant advantage of additional safety and economy.

The ATRS water bags, used to perform load tests on clients’ lifting machines, adhere to the international DNV and ISO 9001:2000 standards. Complete with all the necessary fittings and valves, they are made from heavy duty UV resistance PVC coated fabric and webbing harness terminates. The bags are used by suitably trained personnel only and tests are coordinated by a registered LMI, all expertise is provided by ATRS.

Benefits to ATRS clients increased work efficiency, as the water bags are light, easy to handle, completely rigged and ready to hang and use upon delivery. There is also a 6:1 factor of safety. Through the gradual increase of the load during testing, problems are identified prior to reaching the required load, which can be addressed immediately. Other advantages are versatility, as bags are available in multiple sizes and can be used in combination to achieve almost any load and, weighing considerably less than the required test weight, water bags are economical, saving considerable amounts in transport, storage and labour costs. ATRS says it is able to coordinate complicated projects within shorter periods and without incident.

Applications and use include marine (testing cranes, davits, derricks, winches, lifeboats, ramps, lifts and pad eyes for offshore installations; shipbuilding, repair companies, docks and harbours) and industrial (testing overhead cranes, beams, gantries and elevators at power stations, refineries, factories and crane companies).

ATRS has already completed a diverse range of projects. The latest has been the testing on an oil rig at Coega using water bags.
