Samenvatting

This bachelor's thesis was commissioned by the MSCN Department of MARIN. MARIN will optimize the current evaluation of simulator-runs by adding a workload-assessment. The reason for this research are the developments in the field of Human Performance. Traditionally in bridge simulator studies MARIN looks primarily to the technical, directly measurable, parameters like rudder angles and propeller speeds. MARIN seldom looks for the mental workload of man. This bachelor thesis is written in the context of graduation ashore for the Bachelor of Maritime Operations study at the Maritime Institute "De Ruyter" in Vlissingen. The aim of this research is to design a method with which it is possible to measure workload during simulator-runs as well as on board of seagoing vessels during stressful operations. A general study of literature has been done to determine the correlation between stress and the occurrence of accidents in ship-handling and if stress promotes the awareness or does it adversely. After this introduction, the research question and a global planning of the experimental setup are determined. We will apply the method for measuring mental workload in cooperation with the Dutch Pilot Association, Region Rotterdam-Rijnmond. For the specific test scenario the Calandbrug scenario is chosen. Containing one main tasks (i.e. outbound voyage from the Brittaniëhaven to the 7th petroleum haven). The experimental set-up consists of: a job analysis, expert rating, measuring physiological parameters and subjective ratings. The set up consists of two times a simulator run and once a real world run. During this experiment is to measure performance an expert rating used. Working with an expert works well. Strikingly, performance of participants 1 & 2, is the second simulator run less than the first time. During all experiments, physiological measurements have been recorded, they are available for further analysis. Due to the limited time it was not possible to include the analysis of the physiological measures in this bachelors thesis. All participants described the decision "go for it" as the most stressful. This order follows when the subjects have made this decision. Based on the described experiment can be concluded that increased workload can be measured. The commands and actions combined determine the workload of the marine pilot.
