Seismic Input and Nozzle Evaluation
Seismic Input and Nozzle Evaluation
(OP)
Dear All,
I just want to know, Do I need to subject the vessel connected to the pipe for seismic analysis OR just the pipe only?
Also, Do I have to evaluate the nozzle loads of vessel with seismic loadcase?
Please I need your opinion and expertise.
Thank you.

Marco

for seismic study I think you need to subject it to the whole system (pipe & equipment) as long as it is above ground.
Also, Do I have to evaluate the nozzle loads of vessel with seismic loadcase?
In my understanding No, in fact the nozzle evaluated for the operating load case, because you want to study the loads at the connected equipment for the long run (operating case) not for an occasional moment (seismic)
hopefully it's useful to you.

P.S: Personally I think not considering the seismic loads for nozzle loads is not impeccable!

I have seen a lot of rework required when this is done correctly, for example not transferring the EQ loads from the piping down to the vessel base.
