Robin is now stocking Seaflex WaterLoad bags along with load shackles, as well as Seaflex Lifeboat Testing kits, at his Groningen facility – ready for immediate despatch to meet urgent customer requirements.  Robin will also be representing Seaflex’s market-leading range of buoyancy bags and associated installation aids within his home market.

You can visit Robin and Seaflex  on Stand 11.011 at the upcoming Offshore Energy exhibition at the Amsterdam RAI on October 15th & 16th.

Static Load Testing

Posted in Load test weights, Water filled weights on December 18, 2012 by Seaflex

Static load testing is an essential part of many engineering, building and manufacturing projects. Failure of any load-bearing component, material or structure can endanger lives and cause enormous economic loss. This is why loads and weights must be calculated and tested accurately. Of course, the testing of large or heavy parts requires the use of special equipment.

Water Filled Weights

Water filled weights (also known as ballast bags) provide a very flexible method for load testing. Test weights must be sufficiently heavy to ascertain the maximum load of an object, but they should also be reusable and safe to deploy in a test environment. Hard-filled weights are suitable in many tests, but on the largest scale, water-filled weights provide an ideal solution. When empty they weigh just a small fraction of the filled weight so are easy to transport. In use they can be part-filled for any exacting requirements, or used in combination.

Once filled with water these specially constructed bags can weigh anything from 1,000 Kg to 35,000 Kg, ensuring that objects such as structural beams and crane arms can be tested for durability under extreme loads. Objects can be tested in various ways, for example, test weights might be attached to the centre of a steel arch to ascertain load capacity before being (vertically) affixed to one end to test tensile strength. Understanding how components, parts or materials behave under extreme loads in different positions can help engineers create safer, more powerful systems.

Although capable of being used almost anywhere, water-filled weights are often deployed in docks to ensure that parts can be tested without fear of causing structural damage (failed components and the weights attached to them can simply fall into the water). To ensure that materials are tested accurately, the risk of cable failure is reduced by the inclusion of telemetry dual-load shackles and tensile load cells.

Seaflex 50t WaterLoad Weight

Posted in Load test weights, Water filled test weights on August 2, 2011 by Seaflex

Seaflex lead the way with 50t Water Load Test Weight

The Seaflex prototype 50t WaterLoad Bag has achieved over 201t (safety factor of 4 to 1) during its independent type test at the TUVNEL test rig Scotland.
Managing Director Graham Braiding said “Ideally we would have liked to achieved a 6 to 1 safety factor (300t) but we were limited by the test rig itself which is only rated to 200t” he also pointed out that, “The bag, including all of its lifting components, has been designed with a 6 to 1 safety factor in mind”.

This photo of the bag on the test rig with an operative in the shot gives some perspective of the size of the bag.

To date no other manufacture of WaterLoad test weights has type tested a 50t WLB.

The 50t Bag is now available for hire or purchase from Seaflex, Unique Maritime Group or any of our agents worldwide.
