Can Service Pressure Exceed Design Pressure?

[LS_SMS]

I'm using ASME, year 2023. In Sec. III and Sec. VIII vessel design, is there ever a situation where the service pressure of a defined load case may exceed the design pressure? For example, if design pressure is 100 psi, can I have a service load case that is defined at 150 psi? Please provide citations to the code paragraphs.

A colleagues is referencing ASME Sec. III, NCA-3211.40 where it's insinuated that service loads may exceed design loads. This doesn't seem rational.

MAWP should not be higher than Design Pressure if the allowable nozzle loads and vessel support/skirt design are based on the Design Pressure and the built plate thickness?

Once again, why not read UG-99(c) and try to understand?
