WebBased on all platforms being originally installed for 30 years, the coating breakdown factors used in the calculations for 25 years consider that the initial coating breakdown failure (CBF) is 35%, mean (CBF) is 48%, and the final CBF is equal to 60%. WebThe coating breakdown factor is a function of coating properties, operational parameters and time. The coating breakdown factor fc can be described as follows: where t is the coating lifetime, and k1 and k2 are constants that are dependent on the coating properties.
