Dear all,
I would like to known is there any different between CP dipcheck (potential survey using reference anode) with underwater CP survey on structure and pipeline which the reading is taken directly from the substrate. Some say that CP dipcheck is very important in eveluate the estimated potential to ensure the reading within the range before actual CP survey is happening. Is it justified to remove CP dipcheck,currently it is 3 yearly frequency and only concentrate with underwater CP survey which is 5 to 10 yearly. Appreciate your view.
