Sensitivity Analysis of the Stress State in Shell Courses of Crude Oil Cylindrical Tanks
Original language description
Crude oil is a strategically important raw material, it is thus necessary to pay increased attention to its transportation and storage. This article is aimed at the reliability analysis of a welded cylindrical tank used for the storage of crude oil, which is located near the village Nelahozeves in the Czech Republic. The tank has a height of 24 m and a capacity of 125 thousand cubic metres. The dominant load case of cylindrical tanks is loading of the inner shell by hydrostatic pressure of crude oil. Stochastic sensitivity analysis was used to study the effect of the variability of the thickness of the ith course on the stress state of adjacent courses. The computational model was developed in the programme ANSYS. Meshing was performed using SHELL181 elements. The Latin Hypercube Sampling method was implemented during analysis. Sensitivity analysis based on the evaluation of the correlation between the random plate thicknesses and the stress state was used. The normative approaches in
