Research On Risk Assessment Of D Pumping Station In Myanmar Section Of China-Myanmar Crude Oil Pipeline

As a cross-regional infrastructure,the normal operation of oil and gas pipelines will be a safe,reliable and economical transportation method.However,it should also be noted that in the event of a pipeline leak or other accident,it will bring unpredictable and serious losses to society.China-Myanmar oil and gas pipeline is the fourth largest energy import strategic channel after China’s Central Asian oil and gas pipeline,Sino-Russian crude oil pipeline and sea passage.The China-Myanmar crude oil pipeline has successfully entered the operation period.This is the establishment of diplomatic relations between China and Burma and the promotion of bilateral economy and a important symbol of development.Therefore,the safety of the Sino-Myanmar crude oil pipeline is very important.The D pump station of the Sino-Myanmar crude oil pipeline is located in the mountainous area of northern Myanmar.It is an intermediate pump station that cannot be pressure crossing.It’s safe and smooth operation is on the entire line of the China-Myanmar crude oil pipeline(Myanmar section).It is vital.Therefore,the paper selects the risk assessment of Myanmar D pump station of China-Myanmar crude oil pipeline as the research object,aiming to analyze the risk point of the pump station,the possibility of failure and the severity of the accident,and establish a risk evaluation system suitable for the intermediate pump station of crude oil pipeline.To provide a management references for the safe and smooth operation of the D pump station.Based on the methods of literature analysis and field research,based on the theory and method of risk analysis,this paper studies the risk of the D pump station project of China-Myanmar crude oil pipeline.The full text is divided into the following five parts: the first part,the introduction.Introduce the background and significance of the topic;explain the research status at home and abroad and the main content of the full text;the second part,the theoretical basis of risk assessment.The core concepts such as pump station safety and risk assessment are defined,and fault tree analysis and risk analysis methods are defined.The third part is the fault tree analysis of pump station failure.Taking the D pump station as an empirical analysis case,the accident tree analysis model of the pump station operation risk is constructed,and the D pump station project is qualitatively and quantitatively analyzed.The fourth part is to construct the D pump station risk evaluation index system.The pump station risk assessment model is initially constructed to determine the indicator system and weight;the fifth part is the fuzzy comprehensive evaluation of D pump station risk.Determine the risk level matrix,calculate the relative risk value of the pump station,and propose corresponding prevention strategies.The paper concludes with the conclusion: Firstly,the fault tree model of the failure factor of the D pump station in the Myanmar section of the Sino-Myanmar crude oil pipeline is constructed.On the basis of statistical analysis of the failure accident crude oil of D pump station,combined with theoretical research results,from the five aspects of corrosion,third-party damage,disoperation,manufacturing and construction defects and geological disasters,construct the corresponding fault tree model;secondly,The Kent index scoring method is improved and applied to the risk assessment of the D pump station.The primary factor for determining the failure of the pump station is the geological disaster,followed by the third-party damage factor and the subsequent corrosion factor.Therefore,the weighting indicators of different factors should be different.The index weights must be allocated more rationally,but not all the first-level indicators.Finally,because the weights of the five primary indicators are different,the indicators must be the importance is differentiated,which is reflected in the difference in index weights.Compared with the fault tree analysis model and the Kent index evaluation model,the main difference between the D pump station risk evaluation model and the Kent index evaluation model is that the weights of the five indicators of corrosion,third-party damage,manufacturing and construction defects,disoperation and geological disasters are Differently,the scores of each indicator are re-adjusted by fuzzy analysis to avoid the subjective aspects of the above two methods and ensure the accuracy of the evaluation results.Through the research of the thesis,a fuzzy comprehensive rating index system is constructed to evaluate the risk of the D pump station in the Myanmar section of the Sino-Myanmar crude oil pipeline.Compared with the fault tree model analysis and the Kent index evaluation model,the fuzzy comprehensive evaluation index results are more scientific.
