The key objective of this tank duplication project was to provide duplication of the current storage and pumping system to mitigate the risk to the BHP MAC plant of being reliant on a single system regarding the plant and fire water supply. BG&ER worked closely with Centrals to develop engineering solutions that minimised construction complexities. This included the use of; skid mounted pump assemblies that removed the requirement for several additional site hours; a bolted tank arrangement that reduced the need for working at heights and optimisation of the ring beam design to minimise the need for complex circular formwork. These design solutions enabled Centrals to minimise on site labour and remove scope from the critical path to reduce schedule risks.
