Topside load-out, Koje, Korea

ALE supplied and operated an external ballasting system for the load-out of the 21,800te LUN-A topside, as well as performing the load-out engineering and barge management.

ALE used computer modelling to analyse and design a pumping system capable of delivering the high flow rates
necessary. The systems were based around ALE’s stock of standard 250mm, 400mm and 600mm bore lightweight galvanised pipe lengths and elements. Additional branches were designed and fabricated using 700mm bore pipework to allow for the high flow. The PC-based ballast monitoring system provides real-time feedback from depth transducers fitted into each tank of the barge, and can be pre-programmed with the necessary steps of load-out versus tide and load transfer to target each critical stage of the load-out.
