- Abstract
Independent safe navigation in ice-covered water is difficult. Icebreaker assistance is required for sailing through icecovered waters. Tliis poses an additional risk of collision. The study proposes a modified Human Factor Analysis and Classification (HFACS) framework to identify and classify contributing risk factors dining a convoy. HFACS integration with Nagel-Schrekenberg (NaSch) model considers an operator's behaviour and links it witli the occurrence of various risk factors. The study finds significant influence in risk from small changes in two new' factors, viz., crew' reduction and crew' overload. For example, based on tlie sensitivity analysis, it is determined that about a 17% contribution of crew' reduction and about a 24% of contribution of crew overload increase the contribution of risk taking by an amount of approximately 93% in the overall risk of accidents. The accident probabilities obtained here will be helpful in decision making concerning safe operations during a convoy.
