Hi John
Yes the accelerations are a little on the high side.
I suspect, as Chris indicates, that there has been some "to be sure, to
be sure" going on, because most likely the application will be critical
service.
However in this instance I can see no harm in overdesign, and it may
cost less overall than talking the client around to a rational design
basis.
Cheers
Steve

Subject: Re: [PipingDesign] Seismic response of hydraulic oil tank
Is it possible that you meant 0.10G & 0.50G? Iv'e designed plant piping all over the globe and have never been handed a ground acceleartion of this magnitude...
If this is the correct ground level accelartion please advise where it is because I want to make sure I never visit the area.
