RE: Intelligent pigging of pipeline internal for water/ gas/oil
Frequency of internal inspection is very dependant on the nature of your product, how corrosive it is, what the risks are from leakage and past history of inspections, e.g. you do a run in y1, you do the second in Y6. If this shows up defects which are OK in Y6, but predicted not to be in Y9, then you do a run in Y9. If the defects you leave in Y6 are minor then you can argue not to do it until Y13 or 14.
If you change products to a more corrosive one then you might decrease the time between inspections.
