The existing HSD tank F-6302 has suffered damage in the form of corrosion which has caused the plate thickness to decrease. Developments in analysis methods and tank design standards have an effect on determining the stable capacity of the tank, so it is suspected that this tank is unstable. This study aims to analyze the stability of the existing HSD tank F-6302 to seismic response. The analysis was carried out by collecting structural property data of the tank, modelling the tank in FEM with a combination approach of finite element model and auxiliary mass, and evaluating the stability value of the tank using the equation issued by API 650:2020 to assess whether the tank is stable or not. The analysis results confirmed that the tank was unstable to earthquake loading. This is shown by the tank anchorage ratio values of 2.59 for the empty condition and 3.21 for the full condition. Both are greater than the stable limit value of 1.54. In the future, it is recommended to perform tank shell design and anchorage design on the tank.
