Analysis of LNG Storage Tank Safety: A Comprehensive Model Approach with ANP and Normal Cloud

Global energy shortages continue in the post-epidemic era. As clean primary energy, LNG plays an important role structure adjustment. However, with widespread use of LNG, storage tank leaks occur frequently. In order to highlight risk status critical areas leakage, “Five-high” system for industry, high-risk locations, equipment, processes, personnel, and substances as first-level elements, was built. Combined Analytic Network Process (ANP) normal cloud model quantitative analysis, a safety analysis assessment tanks based on ANP-normal developed. Safety conducted example area factory. The results show that level leakage is IV, equipment being element highest weight risk. reliability comprehensive verified by AHP fuzzy integrated were basically consistent factory evaluation report. study realizes visual considering correlation elements provides new method energy.
