Risk Assessment of Mounded Storage Tanks

The Mounded Vessel is the third form different from the above ground and buried storage containers. In this paper, qualitative and quantitative assessment methods are comprehensively used for risk assessment of Mounded Vessel. Quantitative calculation method is used for failure probability, and qualitative calculation method is used for failure consequence. By comparing and evaluating the risk level of propylene Mounded Vessel and above ground propylene spherical tanks with similar parameters, it is concluded that the failure consequences of Mounded Vessel are smaller, the risk level is lower, and the safety is higher.
