Completion of World’s Largest Water Bag Load Test Without Spreader Beams

Leading integrated subsea and offshore solutions provider, Unique Group, has reported a successful completion of the world’s largest water bag load test without spreader beams.

Taking place last month (November 2020), the 1760 MT proof load test was carried out in the UAE on the derrick crane of M/s Valentine Maritime owned vessel, DLB 1600 Derrick Pipelay Barge. 18 Water Weights and Seaflex WaterLoad bags of capacity 35t, 100t and 110t were used, the latter being the largest water bag available on the market and best suited for heavy load testing applications.

A revolving load test was completed at 1320 MT and the total lifting height of the proof load test was marked at 65m. In order to guarantee compliance with industry guidelines, including those relating to current COVID-19 restrictions, Unique Group undertook extensive QHSE assessments to ensure the safe and timely execution of the project.
