Equivalent shell thickness

[Misaman]

Hi everybody

I am trying to calculate the required equivalent thickness of a vessel using IMDG 6.7.2.4.7 code but the value I get is way too small.
I need help on how the formula works.

The formula is
e1 = 21.4e0d/(1.8(Rm*A1)^1/3)

e0 = 6mm
d = 2.075m
Rm = 485MPa
A1 = 40%

Thank you

why don´t you use ASME?

Its because the client specifically wants the use of this code for equivalent thickness calculation.
