Port planning is a complex multidisciplinary subject. To fulfill its functions, it is essential that the different elements of a port work together. The full potential of a terminal can only be reached when the wet infrastructure of a port (access channel, inner basins, turning circles) can keep up with the traffic load. From the literature study, it has become apparent that simulation tools have become increasingly popular for assessing the capacity of ports and waterways. However, the application has often been aimed at a specific case study and the existing models are not easily reusable for new applications. In this master thesis project, the assessment through a generic simulation tool of the effective capacity of the wet infrastructure of a port is investigated. The model considers the processes taking place from the point a vessel arrives at the entrance of the access channel until the start of the (un)loading procedures and the departure of the port until exiting the access channel. The analysis capabilities of the model are demonstrated by studying the Port of Hazira. The main processes of the model relate to vessels obtaining authorisation to sail towards a destination. To receive this authorisation, the vessels must find a moment when the correct weather conditions occur, the tidal elevation is adequate, the waterways are available and sufficient quay length is available. The authorisation is given in a dynamic way, depending on the dimensions of the vessels, waterways and quays. Based on their origin and destination, vessels can determine their route based on the shortest path available and waterways available depending on their vessel type. Once this is done, a vessel will construct a sailing plan by finding a suitable timeslot to through each section of the port. When doing so, a vessel takes into account the sailing plans of other vessels and the sailing rules that apply for each section. As a result, a vessel can construct a suitable sailing plan based on an origin and destination which can be applied to any port layout. During this study, it has become apparent that many processes should be included to properly determine the capacity of port. Simulation software offers the possibility of including all these processes and observe their interactions in order to locate bottlenecks more efficiently. Simio has proven to be able to incorporate all the required process to properly model the wet infrastructure of a port. However, it does not offer a user-friendly interface to handle different scenarios and facilitate the handling of both the input and output of the model. To this easier, an interface has been created with Scenario Navigator. This interface enable the storing and comparing of input parameters and results of different scenarios.
