The main objective of the MoniRisk project is to develop an integrated system for traffic monitoring and maritime risk assessment. This objective will be achieved by developing methods for the analysis of the maritime traffic and to define safe routes and operational profiles for the maritime traffic off the continental coast of Portugal, tools to detect abnormal traffic behavior and collisions, detailed analyses of important accidental scenarios involving tankers and passenger ships and a dynamic risk index for individual ships and for the marine traffic off the continental coast of Portugal that will combine in probabilistic terms the influence of relevant external (e.g. weather and traffic conditions, anomalous behavior of the ships) and internal (e.g. ship type, age, flag, load condition) risk factors.
