[Need Help] How to estimate coating breakdown factors from CP survey data

[yunanyun]

Hi all,

Need help in finding out how to calculate the actual coating breakdown factors from CP survey data. Data available are the CP measurements, EFG, anode depletion etc. Interested in comparing the values to the calculated in design per DNV code. Really appreciate any help. Thanks!

Delete this one and try int he Corrosion Engineering section.

But please add more information than you have so far (i.e. nothing). e.g. how many years of data do you have and have you got the original as installed data. This sounds like a subsea line?
