ABSTRACT: Natural gas (NG) is one of the widely used domestic fuels in most of the countries, and
because of economical and environmental advantages, its consumption is
continuously increasing. As a result, complex piping systems are being
installed to transport and distribute the gas for end users. Pipelines carrying
NG are a significant source of hazard for their adjacent society. The risk of
this hazard could be high especially in distribution network and urban areas
where the population density is high. The common causes of accident in NG
distribution network are: third party interference, corrosion, fatigue, stress
corrosion cracking (SCC), etc. Accident in network leads to leakage and release of NG and consequent injuries and
losses. To prevent these adverse outcomes, the risks should be identified and
assessed carefully, so that they can be controlled and managed properly.
In this work, risk assessment of NG distribution pipelines was surveyed and quantitative methods were recommended for assessing the individual and societal risks of
distribution network.
