Pipeline Risk Assessment by Using Hazard Risk Assessment, (HAZOP)Method (Case study: Oil transmission Pipeline ofVeresk-Sari,Iran)

Iran is considered as the second country of oil resources. Transmission of oil resource in order to deliver the economic and almost energy from producing sources to final consumers is one the most important tasks and controversial challenges of country’s oil industry and also monitoring organizations such as environment organization.Therefore, pipeline risk assessment is one of the sciences that has been developed by pipelines growth. This article is introducing hazard analysis as an appropriate quantitative method for risk assessment of these pipelines by drawing the amount of risks imposed on this type of projects to reduce hazards and consequently the subsequent financial and human damages and provide information for experts, decision makers, public and private managers involved in all discussions related to the transmission lines. The case study of this research is Veresk-Sari oil transmission pipeline in Mazandaran province in Iran which identify the hazard potentials by using Hazard and Operability Study (HAZOP) method, in this method work space or understudy project is divided into smaller sections, then each hazard is evaluated and analyzed separately by using the identified hazards. High speed and low cost are the features of the method and baseline study is necessary for this method.This study determined that the method is useful in linear projects besides the industrial plant and it’s result is well applicable in risk reduction and management and also accurate results obtained from this method can provide appropriate approach and strategies to reduce the risks and subsequent consequences.
