Tank Shell Design (Pre Design) : API 650 12th Edition Eqpt: Oil Palm Tank One Foot Method

This document outlines the preliminary design of an oil palm storage tank. It provides design conditions such as a maximum liquid level of 10.4 meters and operating temperature of 90 degrees Celsius. Dimensions of the tank include an inside diameter of 8.24 meters and total height of 10.668 meters. Material specifications for the SUS304 steel are given along with required thickness calculations based on the material strength and design parameters. A table shows the calculated thicknesses needed for each of the planned 7 shell courses with the nominal thicknesses meeting requirements.
