Are the foundation bolts for stationary equipment optional?

Are the foundation bolts of stationary equipment optional? I see in many factories and projects that there are plenty of stationary equipment, especially some atmospheric storage tanks, which are often placed directly on the ground. It’s not possible to require them to follow stricter standards, as I myself think it’s not that important
Static equipment generally does not have anchor bolts, but the foundation must be properly constructed.
No, the tower doesn’t have foundation bolts, so it can’t be blown down by the wind.
How strong the wind needs to be? Are resonance and swing amplitude factors considered? As long as there is swinging, and if there are no foot bolts, the swing amplitude will keep increasing. The so-called static equipment without foot bolts is generally at atmospheric pressure and used for storage; it is relatively short and heavy, which is why foot bolts aren’t necessary. However, this definitely does not include towers and reactors, as these are usually slender and tall
Without anchor bolts, can the seismic load calculation be approved?
Which other static equipment doesn’t have anchor bolts, except for the tank wall and bottom that are welded together?
Without anchor bolts, won’t the stress in the pipes cause the equipment to shift?

I’m in the ninth grade now; I shouldn’t be asking such questions
So you’ve never worked on low internal pressure storage tanks. Micro internal pressure storage tanks have lifting force; they are short and stout, and like those filled with liquid, they also require foot bolts
