Abstract: During hydrostatic testing, an 80,000 m³ propane storage tank exhibited subsidence, causing deformation of its outer shell. This necessitated an evaluation of the tank’s operational viability and fitness for service, guided by API 579-1/ASME FFS-1 procedures. The assessment started with Level 1 and Level 2 analyses using distortion measurements, and if needed, progressed to Level 3 for detailed numerical analysis. Results from Levels 1 and 2 indicated acceptable out-of-roundness (RSF ≥ RSFa) and out-of-plumbness (1/200 h_tank) but not bulging, leading to further analysis through elastic-plastic finite element simulation at Level 3. Although stresses exceeded yield strength, the tank was deemed fit for service under plastic collapse and local failure criteria, maintaining buckling stability. Operational recommendations include addressing wind, seismic, and pressure loads and reinforcing and regularly monitoring the shell to ensure ongoing safety and structural integrity.
