A multistage multinational triangulation approach to hazard identification in night-time offshore helicopter operations

摘要

When visibility is poor offshore helicopter operations are prone to accidents. Given that a significant increase in night-time activities is predicted in the near future, this paper proposes a systemic approach to account for all the factors underlying such accidents. It presents the results of accident analysis and interviews of pilots from five different scenarios using cognitive task analysis, followed by rigorous application of Grounded Theory and Template Analysis to the narratives. The results are used to compile a comprehensive list of the factors that affect the ability of pilots to fly at night. These factors should form the basis for future data collection and safety interventions.
