Project Update

Geomarine’s piling works for the new Primary Seawater Intake Structure at BCI Minerals’ Mardie Salt and Potash Project is now complete.

The structure will support 6 seawater intake pumps, delivering 160 gigalitres of seawater annually to the salt-and-potash producing operation, which will be the largest of its kind in Australia.

The team proposed an alternative design that focussed on constructability whilst incorporating locally sourced piles through Gordon Adams Pipe Sales which helped to expedite the construction of the facility.

Roam Marine provided temporary works designs with the piling gate system able to be mounted to excavators utilised for the earthworks activities. In addition to supporting local suppliers, timely delivery of seawater to the network of ponds for evaporation and crystallisation – to commence first production in time – are key drivers of this project.
