Design Optimization of Saddle Support for The High-Capacity Pressure Vessel Using Finite Element Analysis

Abstract

Saddle support is used to hold a horizontal high-pressure vessel in its desired location. Fabrication of saddle regularly supports by referring to the existing code and standard in the code of ASME Code of Section (VII), Division 1 and Division 2 (Boiler and Pressure Vessel Code). This project optimizes the saddle-support structure for a horizontal pressure vessel used in the upstream operation and searches for the saddle-support requirement to enhance its safety factor. First, the existing design of the saddle is gathered from the worldwide source from Design Hub. The finite element analysis method (FEM) is used to analyze the design. Redesign 3D model of the saddle is constructed using SOLIDWORKS 2017 software. Redesign model with a different number of ribs below the saddle-support of horizontal pressure vessel, 2, 4, and 6 ribs. The analysis results are then obtained after meshing the software model using SOLIDWORKS 2017 and testing for static analysis with materials selection. Optimized design develops before in the static loading analysis lives predicted to increase from its original design. Optimized model of saddle support simulated by von mises stresses in the application. Several materials selected for the materials optimization process, such as alloy steel, 1023 carbon steel sheet, and AISI 347 annealed stainless steel was applied to saddle-support with 6 ribs. The force load was fixed to 100,000 N, which is 10 tons. The optimization result was excellent: all the redesign models with new materials passed and safe as per the von mises stress criteria. The optimized design can embrace the load by referring to this factor. Furthermore, the corrosion issue is also considered in the research, including preventing corrosion.
