The growth of the container s market and the search of terminals for the improvement in their port processes has gotten the attention of the scientific area. With focus on simulation studies, the present work aims to model and simulate a logistic system of a port terminal, whose specialization is the containers movements. Six scenarios have been developed in order to assess the resources needed to handle a specific volume of containers by a unit of time. The model is built in the software ARENA and the analysis of results was performed through common indicators in container terminals. These indicators were analyzed for each of the scenarios developed and finally evaluated the installed capacity for each of the scenarios. For de model validation were built two scenarios and for the other four sceanrios assessed how the resources of three berths for ships, 6 ship to shore, 6 rubber tyred gantry, 11 reach stackers, 26 trucks, 4 gates, 1 scanner and 30 inspection slots behaves with 440.000 container/year and 660.000 container/year.
