CP Calculation- Coating Breakdown Factors
CP Calculation- Coating Breakdown Factors
(OP)
I am currently designing some anodes for cathodic protection of flexible pipe. I am trying to calculate the mean current requirement and I have the current density and the surface area however I am struggling to find the coating breakdown factors for the end fittings. They are coated in a Nickel Kanigen coating system. I havent come across this before (havent done cp for flexibles before), and I cannot find a value, or even a mention of this system, in any of the standards I use- DNV RP F103, RP 106, B401, ISO 15589 or in Norsok M503. Can anyone direct me to some more information regarding this coating system, or even if it is similar to a coating system that is considered in the standards- FBE for example? Thanks.

cbf = a + b*t
where t is the design life.
