Environmental Risk Assessment of Product Pipelines by Use of Indexing System Method (Case study: Bandarabbas-Sirjan product transfer pipeline)

This Study has aimed to assess the environmental risk of 26 inch transfer products pipeline of Bandar abbas- Sirjan (273 km) using the indexing system. In this regard, after the identification of the technical features of the project and its environmental impact through library research, risk factors were assessed and risk score was calculated based on relative risk models Muhlbauer. Then, using the capabilities of the software Arc GIS 9.3, points were classified and were located as the areas with high 0.08-0.26), medium (0.26–0.44) and low (0.44–0.62) potential risk along the pipeline route. Finally, to reduce and control the identified risks, some strategic propositions are presented. Result of environmental risk assessment and risk zoning along pipeline route show that 7 of pipeline route meet high potential risk with a risk score range of 0.08 to 0.26 and high potential for soil movement and population density of the most important risk factors are causing. Formulation and implementation of educational programs to alert people the risks of pipeline failure, prediction programs and provide necessary training to emergency response personnel to deal with critical situations can be most effective measures for reducing mentioned risks.
