SHELL STABILITY CHECK;

As per API 650 11th Ed. 2009 Add. 2 Sect. 5.9.7.1

The Maximum height for the unstiffined shell shall be calculated as follows:

23.82 7.26 Meters

Where;

H1 = Vertical Distance in ft, betwwen the intermediate wind girder and the top angle of the shell or the top wind girder of an open top tank t = as built thickness, unless otherwise specified of the thinnest shell course (in Inches)

D = Nominal Tank height, Ft

V = Designed wind speed (3 sec gust)mph 215 t_b ( GH )0.5
