Port Pirie Transhipment Port
Port Pirie, South Australia
|Como Engineers were engaged by WPG Resources as the Owners Engineers Team including Project Director and Project Manager for the design, procurement and construction management of the Port Pirie Iron Ore Transhipment Port at Port Pirie, South Australia.
The Port will be designed to tranship DSO iron ore product from the Peculiar Knob deposit located near Coober Pedy, South Australia for export via Cape-sized vessels moored in the Upper Spencers Gulf.
The Transhipment Port throughput will be designed for 3.4Mtpa.
The existing rail spur to the old Uranium Processing plant will be upgraded to serve the Transhipment Port requirements. Two dead-end spurs each capable of taking 300m long rakes of wagons will be constructed of the main spur beyond the Tip Pocket.
The wagons will be bottom dump type with bomb bay doors to discharge the ore and will unload directly into a bottom dump rail bin.
The rail dump bin will be sized to accept the volume of 4 bulk rail hoppers estimated to each contains 70t, a minimum total of 280t live capacity.
Trains will unload at the average rate of 3,000 tphr (peak design of 3,500 tphr) and will travel continuously at a speed of around 0.4 km/hr while unloading.
Product will be drawn from the bin via belt feeder and discharged onto the inclined transfer conveyor belt CV-01 at an average combined rate of 3,000 tphr to convey the product from beneath the bin to the stockpile transfer point.
The transfer conveyor will elevate the product to the tripper conveyor located inside the bulk storage building.
The tripper conveyor will deliver bulk iron ore product to the stockpiles inside the building.
|The tripper can also direct product to the by-pass system by operating a flop door built into the tripper which will direct product back onto the tripper conveyor and discharge that product onto the tail end of the by-pass conveyor to allow the product to be transported direct from the train unloading station to the barge loader located on Wharf #7.
The warehouse can receive up to 200,000t of product.
Product will be reclaimed from the warehouse stockpiles using Cat 988 front end loaders. The loaders will load into 3 fixed hoppers located above the reclaim conveyor. The hoppers are fitted with belt feeders that will deliver the product to the reclaim conveyor at a controlled rate.
The reclaim conveyor will feed onto the transfer and overland conveyors that will transport the product from the warehouse to the barge loader on Wharf # 7 and over the existing road and rail infrastructure.
The Mobile Barge Shiploader will load product into the Self Unloading Barges (SUB,s) of 12,500t capacity.
Loaded barges will steam 25 nautical miles to the Upper Spencer Gulf OGV mooring where Cape-sized vessels will be moored to receive the product.
Initially, one barge is expected to be used to transport product up to a maximum of 3.91Mtpa.
Contracts were awarded for the following;
The project placed on Care and Maintenance basis pending further need of the Port for other Projects being sought by WPG.
