Risk Assessment of Underground Natural Gas Storage Station

With the development of West-East projects construction, China’s natural gas production and consumption is increasing. But it must be to ensure to supply a continuous gas to users despite pipelines were meeting an accident, solve the inconsistency between storing excess gas during the using troughs and complementing insufficient gas during the using peak, and regulate the gas distribution imbalance caused by gas consumption by day and night and seasonal changes. Underground natural gas storage has unique advantages compared with other methods of peak regulation. The station, as its important part, has many complicated facilities, and the assessment will be extremely important. The paper divided the station into three elements, assessed the risk based on API581. The paper also applied the method to assess these facilities on the station of one gas storage. At last, it presented the suggestive measures to control risks.
