根据AP1581基于风险的检验原理,采用储罐RBI软件对一大型储罐群进行了风险评估,得到了储罐壁板和底板的失效可能性、失效后果与风险等级。通过分析结果,识别出储罐的主要失效模式及损伤机理。针对不同的失效可能性等级和风险等级制定了相应的检验策略,达到降低风险的目的。 According to the AP1581 risk-based inspection principle, a tank RBI software was used to evaluate the risk of a large tank farm. The failure probability, failure consequence and risk level of tank wall and floor were obtained. By analyzing the results, the main failure modes and damage mechanisms of the storage tank were identified. For different failure probability levels and risk levels to develop a corresponding inspection strategy, to reduce the risk of purpose.
