Client Requirement


Following the successful load testing on Seajacks Ltd ‘Kraken’, Unique Group’s Water Weights brand was requested to assist Certex in a proof load test on the sister jack-up ‘Leviathan’.

The client required a 200t load to be applied in increments so they could take comparison readings on the crane’s safe load indicator in order to verify accuracy.

Unique Solution Delivered


We achieved the client’s requirement of 200t by using 6 water-filled proof load bags of 35t capacity configured in two sets of three hung from a Unique Group calibrated 250t load shackle.
All the rigging and loading was completed in a day and our client was very satisfied.
