Abstract

Navigation in ice conditions possess a higher degree of complexity than open water navigation. This complexity has a significant influence in the human performance during the execution of operations. In this paper, a detailed expert elicitation to assess Human Error Probabilities (HEPs) and proposed Risk Control Options (RCOs) in the performance of winter navigation is presented. For this purpose, an evaluation of the Common Performance Conditions (CPCs) of winter navigation operations and the influence from proposed RCOs is elaborated. The process includes the estimation of cognitive failure probabilities extracted from the experts’ elicitation which are subsequently integrated into a Bayesian network model. The results of this analysis identified the operations with the highest need for new actions which can reduce the HEPs. Moreover, actions such as the improvement of winter navigational training, safety and risk management, and electronic navigation support, are identified as key measures to improve human performance.
