Crossing river oil pipeline spill emergency response plan automatic association study based on Apriori‐Topsis

Abstract With the increase in service time of oil pipelines, the probability of pipeline damage increases and the risk of leakage increases. However, as an important equipment for transporting oil, long‐distance pipelines have to be built across rivers. According to statistics, the leakage accidents of oil pipelines crossing rivers account for nearly 50% of all pipeline leakage accidents. Crude oil diffused into rivers easily cause serious pollution and damage to rivers and nearby organisms. Therefore, it is of great significance to study a reasonable, rapid, and efficient oil spill emergency treatment scheme for pollution and property loss. In this paper, an optimization model of emergency disposal scheme based on Apriori‐Topsis is proposed. Firstly, according to the characteristics of the oil spill pipeline, the general scheme library of emergency disposal is automatically generated by association rules, including the type, quantity, layout, and selected disposal technology of oil recovery equipment. Then, combined with the calculation of emergency disposal materials, the multi‐decision technology Topsis model is adopted to optimize the scheme from two angles of oil recovery effect and economic cost, and finally the cost‐effective emergency disposal scheme is obtained. Finally, taking the oil pollution accident on the second line of the Qing river as an example, the optimization model of emergency disposal scheme based on Apriori‐Topsis proposed in this paper is carried out. The application results verify the availability and effectiveness of the model, which provides a new method for the selection of emergency materials for rivers and pipeline process safety.
