بررسی ارتباط شاخص های حوادث با کد ارزیابی ریسک در عملیات کانتینری بندر امام خمینی در سال 94-93

Introduction: Marine transport due to the low cost and shipment of bulk cargo, has a crucial role in trade developments; also container terminals, are an important part of international trade and commerce logistics system. The aim of this study was to assess the risk of jobs in Imam Khomeini Port container terminal operations unit, and comparing the results with safety performance indices. Methods: This cross sectional and descriptive study carried out in an operation unit of special economic zone of Imam Khomeini port container terminal in Khozestan province in 2015-16. Failure Mode and Effects Analysis (FMEA), was used as a systematic approach for risk assessment. Annual Accident Frequency Rate (AFR) and Accident Severity Rate (ASR) indices, were calculated according to the OSHA standard. Data analysis was performed using the SPSS software (ver. 18). Results: According to the results, in container operation a total of 145 risks identified, in 15 jobs studied. The average rate of severity, occurrence and probability of detection, were reported 4.27, 2.64 and 2.36, respectively. The mean and standard deviation of Risk Priority Number (RPN) was 17.7±28.17, and the highest value of the RPN (125) was allocated to the Rich and forklift operators. AFR and ASR amounts (one year) in operating unit, were reported 5.04 and 19.33, respectively. Conclusion: According to the results, in order to calculate the RPN for identified risks, the severity rate parameter in comparison to the rate of occurrence and probability of detection, has a higher average equals to 4.27. In this study, only 6.9% of the risks were categorized in the prominent risk class (RPN>50), and require corrective actions. There is no significant correlation between the RPN (mean) and accident frequency and severity coefficient in 95% of confidence intervals (P>0.05).
