Iron ore explorer Centrex has released its completed study into an alternate low start-up capital cost design option at its Port Spencer development on the Eyre Peninsula.
The alternate design option is based on new CSL transhipment technology that has been recently used at Whyalla for iron ore exports.
The company said today the option significantly reduces the initial capital required for the Port Spencer development.
“The new CSL transhipper technology comprises a self-powered self-docking vessel, which replaces traditional barge and tug arrangements and also eliminates the need for tug berthing facilities,” the compnay said in a statement to the stock exchange.
“This means a significant reduction in operating costs compared to traditional transhipment options.
“Using a 15,000 tonne CSL transhipper reduces the required loading depth at Port Spencer to 7m at low-tide, and through the use of both bow and stern thrusters the transhipper can manoeuver itself to load under a simple point shiploader.
“Allowing for a 10m loading depth to be able to handle larger 25,000 tonne transhippers in the future, the effect of the new design option is a reduction from the currently designed 515m jetty plus wharf and traveling shiploader, to a 200m jetty with a point shiploader and mooring fenders, significantly reducing the capital costs for the dcevelopment.”

Under the new design option the transhipper would load Cape-class vessels anchored approximately one nautical mile offshore in a water depth of about 23m.
The transhipper would also be capable of loading of smaller Panamax-class vessels required for grain exports.
The company said the transhipper has the ability to self-clean, with all cleaning water retained onboard for eventual disposal at appropriate on-shore facilities.
The onshore design provides site works for start-up iron ore volumes from Centrex’s own projects and joint ventures in the region delivered via slurry pipeline and road, however it still retains full expansion capability for third party users, and allows for implementation of a rail loop if required in the future.
