Merino da Silva, D. and Ventura, M. (2015), “Analysis of river/sea transportation of ore bulk using simulation process”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 109-118
This work presents a study of the transport of iron-ore by river-sea bulk carrier(s) from a river terminal in river Douro to a sea terminal in Aveiro, in the Portuguese west coast. The objective of this study is to make a detailed analysis of this transport problem, in order to obtain the optimum characteristics and specifications of the involved terminals, infrastructures and vessel fleet. The terminals design approach is made by means of simulation. A model was developed, including ships and terminals, which specifies and relates the main parameters that influence the transportation, in order to emulate the real process as close as possible. For the simulations, several scenarios of terminal configurations and cargo equipment were created. All these scenarios were compared by the analysis of performance measures such as: annual cargo throughput, port time, waiting times, berth times, rate of equipment utilization in the terminals. Finally some conclusions are drawn from the obtained results about the relative merit of the proposed scenarios.
