Abstract Process pipelines are essential for operations, but their failures can have severe consequences. This study investigates and analyzes the consequence modeling of the pipeline corridor located in southern Iran. It also determines the restricted and impacted areas around the pipelines using PHAST software. The consequence modeling of the main scenarios, including flammable and toxic gas dispersion, fire, and explosion, is analyzed. According to the results, the restricted and impacted areas around the pipelines are 426.9 meters and 454.3 meters for section 1, and 648 meters and 802 meters for section 2, respectively.
Following the results, preventive and mitigative measures are recommended to lower risks. Multiple strategies should be employed to reduce the risks associated with the pipelines. Some strategies aim to decrease the frequency of incidents, while others focus on reducing the impacts and consequences of leakage, rupture, or any other type of containment failure.
