Health, safety and environment risk assessment in gas pipelines by indexing method:case of Kermanshah - Sanandaj oil pipeline

Background and Aims: Using pipelines for oil products transportation involves ranges of safety, health and environmental risks, this option however, is dominant with numerous advantages. The purpose of this study was; relative risk assessment of abovementioned risk in Kermanshah-Sanandaj Oil Pipeline. Methods: The method used in this study was Kent Muhlbauer method in which relative risk was assessed using third-party damage, corrosion, design, incorrect operations and leak impact factor. Results: Once applying this method, collection of required data and performing needed experiments, scoring results showed 96 risk segments along the pipeline length in which lengths 100+860, 101+384 and 103+670 had relative risk scores 9.74, 9.82 and 9.91 respectively and therefore these segments were identified as focal risk points and priority for improvement actions. Conclusion: Regarding importance of pipeline failure, inspection and regular patrol along the pipeline route, precise control of cathodic protection of pipeline and using communication technologies such as SCADA or optical fibers along the pipeline route were amongst the most important control action suggested by the study.
