CraigB,

I would make a problem.
There is not spring, only +y support at first support of pump suction with satisfied nozzle load(actual: 50kg, allowable: 60kg for y force of non API pump 6"x4").
This system will be perfect for report mathematically maybe.

However, allignment, that is problem. The +y support with adjustable type can be moved(up or down) when alignment is done. After finish alignment, I guess that support loaction might has been changed. In this case, do I have to use INITIAL DISPLACEMENT when SUS case? maybe, the answer is "no"
then, why? I don't understand why we have to ignore it at sus case. If I consider initial displacement like offset when SUS case, nozzle load may be over than allowable load of 60kg. Shall I use this method?

I want to apply realistic analysis between CAESAR II and field.
And also, I think Judgement can be done case by case if a few of displacement is occured and pump has a small allowable load like above example.
How do you think about that?

Best regards,
