ASME B31.8 and DNV-RP-F112

ASME B31.8 and DNV-RP-F112

(OP)
I have been working on a subsea project and the client wants the piping to be designed to both ASME B31.8 and DNV-RP-F112. I am currently using AutoPIPE to run all the piping analysis, but its results are only per B31.8 (hoop, longitudinal & combined).
However, DNV-RP-F112 gives its allowable in terms of (membrane & membrane + bending....stress linearization)

My question; is there a way of obtaining membrane & membrane + bending stress components from B31.8 stress components?

Any help or nudge in the right direction is greatly appreciated.

DNV-RP-F112 - "Design of duplex stainless steel subsea equipment exposed to cathodic protection"
 

RE: ASME B31.8 and DNV-RP-F112

Autopipe also gives you the internal forces/moments at the node points. So knowing the pipe dimensions you can therefore calculate the membrane, membrane+bending etc from the output.

Thank you very much, I will look in to that. Hopefully I'll get comparable results from a simple model I run using ANSYS.
