Abstract: Provided are systems and methods for vessel risk assessment. This includes determining a risk assessment associated with a vessel, including receiving vessel data from at least one source, generating at least one vessel profile based on the vessel data, wherein each vessel profile provides indication of expected behavior events for one vessel and abnormal behavior events for one vessel, determining at least one abnormal behavior event of the vessel based on the at least one vessel profile, each event in the at least one abnormal behavior event having a time of occurrence, determining at least one frequency of occurrence of abnormal behavior events of the vessel based on the time of occurrence of each event, using at least one model to determine a risk assessment associated with the vessel based on the at least one frequency of occurrence of abnormal behavior events of the vessel.
