Iran is considered as the second country of gas resources. Transmission of gas resource in order to deliver the economic and almost clean energy from producing sources to final consumers is one the most important tasks and controversial challenges of countryÂ’s gas 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 Savadkooh 16 inch gas transmission pipeline inMazandaran province in Iranwhich 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 itÂ’s result iswell applicable in risk reduction andmanagement and also accurate results obtained from this method can provide appropriate approach and strategies to reduce the risks and subsequent consequences.
