Design Calculation Description :
Design and Lifting Calculations for Chemical Injection System Skid of this project is written in MS-Excel for the purpose of calculating the optimum sizing of lifting gears . Specifically, the design is based on Bending Equation formulas and Standard engineering formulas & AISC Lifting calculations is used to analysed the required dimensional thickness and strength of the lifting lugs
(Skid & its tank) during lifting operation. Bending equations of "Simply supported beam" and "Statically indeterminate beams" are used in calculating required size of the spreader beam section used. The slings and shackle sizes are also selected after selection of lifting lugs for the tanks and skid . STAAD PRO software is used to facilitate analysing skid structural frame strength.
The formula for determining the bending stress in a beam under simple bending is :
σ is the bending stress
M - the moment about the neutral axis
y - the perpendicular distance to the neutral axis
Ix - the second moment of area about the neutral axis x
b - the width of the section being analyzed
h - the depth of the section being analyzed
Weight and Centre of Gravity Calculation Description :
Weight for Chemical Injection System Skid of this project is written in MS-Excel for the purpose of calculating the lifting weight of the Skid. STAAD Output result from post analysis during lifting is able to calculate the Centre Of Gravity (C.O.G) of Skid and its Equipment during lifting operation.
Design Calculation Assumptions :
4. The Bending stress formulas in the calculation are based on the following assumptions:
(4.1) The beams are assumed to be symmetric about the x-y plane
(4.1) All loads must act in the x-y plane.
(4.1) A right handed coordinate system is adopted, with x-axis along the longitudinal axis of the beam.

I recommend to put the two programs in one file/spreadsheet to minimize errors in the calculation.
