For these reasons it is becoming very important to develop methodologies and techniques to support risk analysis and environmental impact assessment in this sector. Given the evolving nature of port terminals it is critical to integrate field measurements and data collection with predictive models, to be able to estimate the effect of changes and improvements (Bruzzone et al., 1998). So, the authors are working on the development of a simulation environment to perform risk analysis related to harbors, port terminals and maritime environment.
