Abstract :

Background and Objective: This study analyzes the risk assessment of Gachsaran petrochemical Ethan transformation 20 inch pipeline implementation design as one of the most important petrochemical designs of the country, with the knowledge of assuring necessity of proper and right implementation of projects and finally presenting solutions for adverse effects reduction on environment. Method:  VIKOR and ENVID methods are types of environmental risk identification methods that show necessary applicability for projects’ risk amount assessment. Findings: In this research, relative analysis process of failure existence potentials is discussed and also sensitivity assessment and vulnerability detection of environment around us is done. This method conclude recognition of environment affected by gas leakage, important ecologic compartments checked and assessed considering environmental sensitivities, risk amount guaranty according to existing standards and identification of preventive actions and potential pipeline risk reduction actions. Discussion and Conclusions: The results show that in both mentioned methods, construction phase has more risk in comparison to application phase as in construction phase, physical and chemical and economical, social and cultural environments respectively get the most influence and in application phase with less severity comparing to construction phase Economical, social and cultural and physical and chemical receive the most influence.
