Human error has long been recognized as a cause of trouble and accidents in the maritime field. However, in order to take effective measures to improve safety, it is necessary to inquire further into the fundamental causes giving rise to such human errors. According to some accident investigations, the state where officers don't achieve the necessary tasks for safe navigation often causes dangerous situations. These necessary tasks are determined by changes of navigational situations. Officers have to achieve these tasks, which is indispensable for achieving safe navigation. Therefore, the necessary tasks can be regarded as the workload on officers. The level of workload on officers affects on the level of competency they show. The heavier the workload, the less officers can be relied upon to achieve the necessary tasks expected of them. In this paper, we focus on the necessary tasks for safe navigation, and quantitatively study human errors from the view of the relation between the workload and achieved degree.
