Good Morning to all.

When we define two seperate vectors for PSV forces, what kind of cases are to be prepared for OPE/STNDBY Conditions?

Type 1

W HGR
W+T1+P1 HGR
WW+HP+H HYD
W+T1+P1+H OPE (Operating Line Temp/ Both at OPE)
W+T2+P2+H OPE (Design Temp/Both at Design)
W+T3+P3+H OPE (Operating PSV1 & STNDBY PSV2 at OPE Temp)
W+T4+P4+H OPE (Operating PSV2 & STNDBY PSV1 at OPE Temp)
W+T5+P5+H OPE (Operating PSV1 & STNDBY PSV2 at DGN Temp)
W+T6+P6+H OPE (Operating PSV2 & STNDBY PSV1 at DGN Temp)
W+T7+P7+H OPE (Steam Out Temprature/Both at SO Temp)
W+T1+P1+H+WIN1 OPE
W+T1+P1+H+WIN2 OPE
W+T1+P1+H+WIN3 OPE
W+T1+P1+H+WIN4 OPE

I have a confusion on PSV force case (In Bold) that is it to be combined with T2 or with T5/T6 at respective STB/OPE cases.

I am with TYPE 1 cases as we are defining two sepetate force vectors, you need not combine it with T5/T6 as they are same but other PSV is at standby condition.

CORRECT ME IF AM NOT.
