Answering your points:

1. You try to identify potential sources of vibration such as connected equipment, fluid flow, wind, seismic or other imposed excitation.

2. Clearly at the design stage, predicted vibration and resulting resonance can be prevented with proper use of restraints, snubbers etc.

Are you a piping designer (draftsman)or a stress engineer ? I would expect a stress engineer to be able to deal with site vibration problems.

Many problems with vibration are only evident in the field. You may need to employ an expert for your field work. Don't try to wing it. Catastrophic failures can and do occur due to vibration, and they can happen without warning.
