The role of marine engine accident prevention has become more important for marine engineers working in a complex environment. Various risk factors caused by human errors result in serious accidents. However, this argument does not account for the relationship between error and accident. The purpose of this study is to introduce an integrated multi-dimensional approach to investigate errors committed by engineers. For this work, the characteristics of total human errors were investigated by taking 298 marine accident records from the Japan Marine Accident Inquiry and 104 incident records from engine trouble casebooks. Different incident records are compared by employing quantification theory III, which is one of the measurements for multivariate analysis. This research identifies actualized and latent events by using accident records and incident records without near-accidents. Furthermore, the authors present recommendations for safety guidelines required for safe engine operation by analyzing both compositions of factor and total image errors.
