A major milestone has been achieved on the Mardie Salt and Potash Project in Western Australia, with the successful demobilisation of its Canti-Traveller system.
The Traveller Systems is equipped with a hydraulic launching system that enables the Traveller to launch forward and back along the jetty on roller assemblies fixed to headstocks.
The Mardie Project will develop a large-scale, solar evaporation operation on the Pilbara coast.
Once complete capacity of the facility is estimated to be 5.35 million tonnes per annum of high-purity salt and 140,000 tonnes per annum of sulphate of potash, over an operating life of at least 60 years.
McConnell Dowell will deliver the scope of works which includes the design, supply, fabrication, construction, installation, testing and commissioning of a piled 2.4-kilometre jetty structure with head-end platform, berthing and mooring dolphins.
Construction involves anchoring to the ocean floor more than 200 steel piles, each up to 30 metres long and weighing a combined 3800 tonnes.

Other works involve a materials handling conveyor system including shiploader, non-process infrastructure comprising fire suppression equipment, employee amenities and fixed crane, channel markers.
Following the completion of the 2.43-kilometre approach jetty constructed from the Canti-Traveller, McConnell Dowell’s marine spread – comprising of the MCD914 Jack-Up barge and supporting floating barges– efficiently removed all parts of the Traveller in under 10 days.
With the largest lift of nearly 150 tonnes, the newly developed large module demobilisation method significantly accelerated the process.
This successful operation has enabled McConnell Dowell to quickly advance to the next stage of marine construction, including incline conveyor setup, jetty head, berthing, and shiploader structures.
