Abstract:

Shipyards are work areas where shipbuilding, maintenance, repair and dismantling activities are carried out and a large number of employees are employed. This situation makes a significant contribution to the country's economy in terms of providing production, employment and meeting the defense needs in terms of maritime transport. In addition to these, when shipyards are evaluated in terms of the different activities carried out and the working methods that help in the execution of these activities (working on the pier, on the ladder, working with work equipment, working on cranes, etc.), they are areas with a high probability of occupational accidents. Accidents, especially in working at heights, can result in death. Preventing accidents can only be possible by examining the risks and taking the necessary precautions. In this context, in this study, it is aimed to analyze the risks of working at height in shipyards. AHP-based PROMETHEE method was used as the method. In the first stage, seven criteria as risks of working at height with literature research; “Inspection and maintenance, training, personal protective measures and collective protection methods for the prevention of “employee falling, material falling, electric shock, overturning/collapsing of scaffolding/ladder, crash-collision, static calculation and engineering errors and meteorological conditions” and fall from height accidents. Four alternatives have been identified. In order to make a pairwise comparison of the criteria and a pairwise comparison of the alternatives according to the criteria, the questionnaire prepared using 1-9 comparison values was evaluated by the experts working in the shipyard, and the criteria weights were determined by entering the data into the Super Decision v2.1 program that operates with AHP. According to this evaluation, it was concluded that the criterion of employee falling is the highest risk. In the next step, the criteria weights and pairwise comparison data were entered into the Visual PROMETHEE program and the priority order of the alternatives was determined. As a result of this evaluation, Inspection and Maintenance came first as an alternative. Especially guardrail, safety net etc. to prevent employees from falling. Giving priority to the implementation of collective protection methods and continuous inspection and maintenance activities will eliminate risks and reduce the probability of accidents. In this study, it is aimed to contribute to the literature and to shed light on similar studies by analyzing the risks of working at height in shipyards with the AHP-based PROMETHEE method.
