Subsea hydrotest pressure B31.8 VIII - 01/31/18 11:59 PM
Subsea pressure is defined as: P = Pi - Pe
P will be put in hoop stress equation P*D/(2t) for code check. As I know, by defining wave, CII will calculate Pe to implement the (Pi-Pe) term in the hoop equation
For hydrotest case as defined by Project: P = 1.25*(Pi-Pe) = 1.25*Pi - 1.25*Pe
The value 1.25*Pi can be input in Classical Input. And there is no change in wave data, I think CII will calculate Pe only. The 1.25*(Pi-Pe) term is required for Hoop stress calculation
My question: how to tell CII to calculate 1.25*Pe?
