The Tanjung Perak harbour ofthe city of Surabaya on the island Java, Indonesia has experienced a considerable growth of container traffic. In order to adequately deal with the expected continuing increase ofcontainer traffic in the future, the International container terminal is presently being expanded. In future there will be three independently operating terminals: two terminals for international container traffic (ICT) and one terminal for inter island traffic (IIT). The Inter Island Terminal will handle coasters operating between the larger and smaller (more inland located) ports. The quays of these three terminals will be connected to the container yards by one bridge. Evidently the expansion ofthe container terminal will create a new situation on the whole terminal, in particular on the bridge connecting the quays to the container yards. The objective ofthis thesis research is to investigate the capacity ofthe future container terminal and to analyse possible future bottlenecks (with emphasis on the bridge situation). For this purpose computer simulation models have been created of the three terminals and the bridge. The first phase ofthe research concerned the creation of a simulation model ofthe terminal as it is operating at present. This model was verified and validated using the 1997 data records of the terminal. Since the operations ofthis terminal will not change drastically once the expansion ofthe terminal is completed, this simulation model of the present terminal has also been used as the basis for the simulation ofthe future terminals. In the second phase three simulation models have been developed: one for the new international container terminal, one for the inter island terminal and a model of the bridge. Using above simulation models the future terminal operations have been analysed and in the process also an indication ofthe capacity ofthe terminal is obtained. The models enabled a better insight of the possible container throughput of the terminal in relation to the efficiency level ofterminal operations and upgrading of equipment. The traffic load on the bridge has been investigated by analysing the varying traffic flows generated by the terminal models. Concluding it appears that there are two factors that may limit the anticipated container throughput increases per terminal: the capacity ofthe portainers and the stacking area ofthe container yards. In case the container throughput per terminal increases as expected and the efficiency levels can not be improved (thus limiting the production of quay cranes), the possibility ofa serious congestion ofthe terminal may be the result. This would result in increased anchorage waiting times for the vessels and in a further increase ofthe quay occupancy (more than the present 70%). Also the capacity ofthe stacking areas may prove to be insufficient to cope with this increased container throughput. These effects also imply that the terminal will not have an adequate safety margin to handle unforeseen delays, for instance equipment breakdown. If on the other hand the efficiency of terminal operations can be improved (thus enabling a higher portainer production) and if the dwell time of the containers in the container yard can be reduced, then the terminal will be able to handle a maximum of about 1,400,000 boxes (which is about 2 million TEO) per year, assuming that the present quay occupancy of approximately 70% is maintained.
