Due to the extent of lines in various facilities or even residential areas, as well as the high potential of vulnerability, the safety of pipelines and compliance with the principles of risk management are of particular importance. This research was conducted with the aim of risk zoning of the pipeline route using the FAHP method and integration of RS and GIS information in the Maron oil field area of Khuzestan province. In the risk zoning of the pipeline route, after identifying the effective layers (facilities/technical and environmental), the weight of each of the criteria and sub-criteria was calculated using experts' opinions. The risk map of pipelines was estimated from technical and environmental perspectives. Then the maps obtained from environmental and technical point of views were combined to prepare the final risk-zoning map. The result showed that in the south and southeast of the region, the route of the pipelines can be more risky in case of accidents caused by the leakage of liquid petroleum products. other areas. Also, the level of risk caused by the leakage of liquid petroleum products is much higher than the leakage of gas in these areas, and it includes about 30% of the pipeline route of the oil field. According to the land use map of the region, this route passes mostly through agricultural lands, main roads, and bridges. As a result, being aware of this issue, the consequences of accidents with proper management of this issue can be controlled.
