We helped revolutionise the design and construction approach for large-scale marine infrastructure on Rio Tinto's Chith Export Facility project in remote Far North Queensland.
The 350m wharf structure was split into seven, first-of-a-kind ‘jacket’ modules (the substructure) and six topside modules. Weighing approximately 680 tonnes each and standing 30m high, the jacket modules, with integrated dolphins, reduced the number of permanent wharf piles required from 100 to just 28, minimising environmental impact to marine life – a core focus for the Chith Export Facility team.
The wharf topside modules, placed on the jackets, ranged from 600 to 1400 tonnes and were fabricated complete with all services, conveyors, concrete roadways and access walkways.
In true ‘plug and play’ fashion, the modules were delivered and installed by a heavy-lift ship in a safe, clean and efficient operation.
The project, completed in just 10 months, was awarded the Australian Construction Achievement Award by Engineers Australia and the Brunel Medal by the Institute of Civil Engineers (UK).
