Dear all kind-hearted friends,
Would you please do me a favor on piping stress analysis issue for marine case?
Is there a recommended load case combination for FPSO? I understand there would be many factor need to be considerred, such as wave motion, deck deflection, wind, etc. I also checked the DNV-RP-D101 for some information.
As onshore, the wind and accelaration will be treated as OCC load, and we will take the factor 1.33 on considering stress range, however for FPSO, I think the wind and wave motion should not be seperated, if I treat this comination as OCC, does that means the factor should be 1?
I also concerned about fatigue analysis for piping, but not figure out a solution, does any professionals here have good suggestions?
Thanks a million in advanced!
