1.0 INTRODUCTION The anti-foam injection package skid (A4401) is modelled and analysed in STAAD PRO software.Stability and design strength of the structural framing is verified for loading conditions encountered during the entire life span of the structure. The design check is performed using BS 5950. Skid is analysed for 3 different types of loading:1) In place analysis 2) Lifting analysis 3)Transportation analysis Structural framing subjected to in place loading, lifting loading and transportation loading is checked for worst case combination of loadsacting on the structure and all members are found satisfactory. 1.1 Configuration ofskid Below is the snapshot showing general configuration and framing of skid.
