Hi,

I'm checking the offshore piping which concerned about pipe riser (B31.8 VIII) and topside piping (31.3). I found some question that the 3D max intensity stress of riser line is greather than allowable stress (as per B31.8 VIII) in case of Hydrostatic test case (HYD).
I have read article about 3D max intensity stress in this forum. But I dont clear about the criteria.

In my case that's mean the system is passed or not??? Because the other stresses (hoop, axial, bending) are passed comparing to piping code.

If yes, how can I ignore this stress check in my analysis. Absolutely, it will be a question from Client!!

If no, how can I minimise this stress???

Thanks..
