Sandwell conducted a feasibility study for the proposed expansion of P.T. Kaltim Prima Coal's export terminal in East Kalimantan, Indonesia. As part of our study for a planned doubling in coal output from this terminal, we developed an animated simulation model to determine the optimum design of the expanded terminal.
The model shows the operations for the mine stockpiles, overland conveyors, terminal stockpiles, stackers, stacker/reclaimers, reclaimers, surge bin, trestle conveyor and dual quadrant shiploader.
By simulating the detailed routing of coal through the system, it identifies conflicts with other coal flows and pre-empts equipment when appropriate. Introducing different throughput levels allows the user to evaluate bottlenecks and potential demurrage costs against the expense of adding another shiploader or another berth.
First developed in 1996, this model has since been broadened to include the mine wash plant, preparation plant, mine stockpiles and reclaim system. Truck dump hopper capacities were examined, along with overland conveyor rates, shiploader type and design rates for several throughput levels, ship fleet sizes and commodity mixes.
