报告摘要:New methodology for risk based approach to structural life assessment of pressure vessel has been introduced. Namely, 3D risk matrix has been defined with consequence axis taken as usual, whereas probability axis has been separated into two, covering effects of human factor and material defects. Toward this end, Failure Assessment Diagramme (FAD) and Paris law have been used here as simple engineering tool to estimate probability of the elastic-plastic fracture and fatigue failure, respectively. Probability of failure due to human factor has been estimated according to the survey performed (with operators and managers). With consequence estimated according to simple standard procedure (1-5, pxV itd), or by using more complex procedures (API 581, RIMAP), the novel risk based structural assessment has been completedThis simple engineering tool to assess structural integrity and life is also useful for management to make decision making process easier and more reliable.
