Analisa Kekuatan Dinding Tangki Terhadap Kemiringan Pondasi Menggunakan Metode Elemen Hingga

Abstract

Storage tanks are essential equipment in oil and gas facilities, designed to store crude oil and natural gas before their distribution based on needs and demands. These facilities frequently encounter issues such as land subsidence or shifting caused by weather and ground movement. Such ground movement can alter the position of the tank foundation, leading to uneven tank bases and causing the tanks to tilt. Tank tilting impacts the structural integrity of the tank walls, necessitating an analysis to ensure that the tank structure can evenly distribute stress.This analysis employs the finite element method (FEM), focusing on a scenario where the tank body tilts on one side. The process involves collecting technical data, creating a geometric model, performing FEM simulations, and drawing conclusions. Simulation results indicate that the highest stress and deformation occur at the tank base, with stress measured at 21,050 psi and maximum deformation at 2.523 mm. These values are within the allowable stress limit for SA 283 Gr. C material, which is 23,600 psi.Consequently, the out-of-settlement conditions for Tank T-02, as determined by FEM simulation, confirm that the tank remains safe to operate in accordance with its specification standards.
