Oil and gas transported by station pipeline are flammable and explosive. When a leak occurs, it can easily result in casualties, environmental pollution, and loss of property. Risk assessment methods for a station pipeline are less current. The traditional way to manage a station pipeline in the past 40 years in China, heeds only some of the relevant laws or regulations about station pipeline. The inspection cycle time of station pipeline is fixed. Some station pipeline may not need to be inspected in the fixed cycle time. For a more rational use of inspection funds, developing a method for determining inspection cycle time is important. This approach provides risk assessment for station pipeline. The article introduces the risk calculation model for station pipeline, including the determination of the scenario and the likelihood of failure (LOF) of station pipeline. The risk assessment method is improved when combined with the domestic situation, and has applied by the PetroChina Pipeline Company. Practice shows that the evaluation result gives the risk ranking of station pipeline in the company. Then, the station pipeline inspection cycle time is determined in accordance with the level of risk. The risk assessment method provides a scientific basis for formulating the station pipeline inspection plan.
