Project Description
Centrex has completed a prefeasibility study (PFS) on an alternative low start-up capital-cost design option at its Port Spencer development on the Eyre Peninsula, in South Australia.

The alternative design option is based on new CSL transshipment technology that has been proven in the region at Whyalla for iron-ore exports.

The technology significantly reduces the initial capital required for the Port Spencer development, but retains the ability to increase capacity in the future to handle foreseeable bulk export volumes from the Eyre peninsula through the use of larger or multiple transshipment arrangements. The new CSL transshipper technology consists of a self-powered self-docking vessel, which replaces traditional barge-and-tug arrangements. It also eliminates the need for tug berthing facilities. This means a significant reduction in operating costs, compared with traditional transshipment options.

Using a 15 000 t CSL transshipper reduces the required loading depth at Port Spencer to 7 m at low tide and using bow and stern thrusters enables the transshipper to manoeuvre itself to load under a simple point shiploader. Allowing for a 10 m loading depth to handle larger 25 000 t transshippers in the future, the effect of the new design option is a reduction from the currently designed 515 m jetty with a wharf and travelling shiploader to a 200 m jetty with a point shiploader and mooring fenders, significantly reducing the capital costs for the development. In the new design option, the transshipper will load Cape-class vessels anchored about one nautical mile offshore in water about 23 m deep. This depth will also allow for future larger vessels, if warranted. The transshipper will also be capable of loading smaller Panamax-class vessels required for grain exports.

Value
The PFS estimates the cost of the project at A$142-million.
