This paper presents a novel non-parametric methodology – rough set theory – for accident occurrence exploration. The rough set theory allows researchers to analyze accidents in multiple dimensions and to model accident occurrence as factor chains. Factor chains are composed of Seaman characteristic, ship’s characteristics, navigational behavior and environment factors that imply typical accident occurrence. Rose2 software tool is used. The purpose of this application is to find out the critical attributes to reduce the number of the fatality in maritime accidents. This paper explains the application on the accident reports of Accident Data database, containing data records for all categories of maritime accidents between the years of 2003 and 2009. Variable precision rough set is used to reduce the attributes of data set. The categorization tools and decision trees are used to find the relations and rules about the accidents resulted in fatality. Some rules about the fatality are obtained and also the attributes that affect the fatality in the incident have determined.
