Calculation of thickness for LPG tank as per ASME code

[consald]

Given following details I require a min thickness for shell and heads and calculation as per ASME Section VIII part 2 for a pressure tank for LPG use.

Steel: fully killed fine grain carbon manganese steel - Type T St E 355 DIN17102 MOD
Design Pressure : 17.6 bar g
Temperature: -10 C to +45 C
Max yield stress : 355 N/mm2
Max tensile strength: 520-580 N/mm2
Shape of vessel : Cylindrical
Length: 17100 mm
Diameter : 8300 mm
max sp. gr of cargo: 0.652 T/M3
geometric volume: 769.7 m3 including volume of domes
corrosion allowance: 1 mm
maximum internal pressure 1.144

Consald-

I'd suggest you hire a consultant familiar with pressure vessel design to evaluate your problem and come up with a design. Methinks there is more to this story than we know...

consald,
There are millions of LPG tanks around the US and Canada, so LPG vessel design is common knowledge. Apparently your tank is destined for eurozone with your metric units. I have little experience with PED and similar requirements. The ASME vessel Code would have design allowable stresses to use for listed materials with minimum specified yield and minimum specified tensile, instead of a maximum yield or maximum tensile. (Probably talking about same thing.) Your steel of Type T St E 355 DIN17102 MOD might not be acceptable for ASME pressure vessel design without a Code case. Of course, there are vessels designed to ASME but not stamped with ASME approval.
The minimum design temperature needs to be re-evaluated. My data for LPG (propane) has boiling point 1 atm at -43 deg F or a -42 deg C that could require impact tested steel.
I am not sure what is meaning of the last line of
"maximum internal pressure 1.144 "

The suggestion by jte to seek a consultant would certainly be worth it considering the value of this size of vessel.
