ABSTRACT

Cranes are equipment used in multiple areas such as shipbuilding industry, construction sector, factories, ports, railways, rescue works and etc. in daily life and provide excellent convenience in lifting and transporting heavy loads. There are many different types of cranes according to their usage areas and load-carrying capacities. Due to heavy load handling operations; shipyards are one of the most used places for cranes. Portal, tower cranes are the primary, and mobile cranes are the preferred crane types in shipyards. The extensive use of cranes has brought occupational accidents. Between 2010 and 2015, 77 related occupational accidents in Turkish shipyards were identified. In these accidents, being struck by load was the most common type of accident with 62.3%, followed by load drop at 28.6%, falling from height at 7.8% and electrocution at 1.3%. Crane tip over, crushed during assembly, and boom/cable failure are other risk factors with a high probability of occurring. In this study, crane accidents in shipyards were examined and risk analysis in cargo handling operations was carried out using the Functional Resonance Analysis Method (FRAM). Technical, organizational and human factors were determined according to the typical performance requirements of FRAM. Crane load handling operation is divided into 11 functional modules and risk factors for these functional modules are evaluated accordingly. As a result of the FRAM analysis, the performance fluctuation of the functional modules 'Lifting the load by crane' and 'Carrying the load' is high. These two functions have been determined as functions with increased accident risk in load-handling operations with a crane. When the functional resonance relationship is examined, 'Connecting the load lifting apparatus', 'Visual inspection of the crane', 'Determining the communication procedure before the operation,' and 'Stacking the load to be transported' are determined as critical functional modules. The physical, functional, symbolic and invisible barriers were revealed to prevent accidents and eliminate risks.
