Abstract
A previously developed mathematical model describing the formation of calcareous deposits on cathodically protected steel in seawater has been improved. By entering geographical coordinates of interest and a time duration, current density requirements and surface coverage of calcareous deposits as a function of time and depth are predicted. From this data, surface plots of current density requirements and calcareous deposit coverage can be easily created. The data can also be used to construct polarization curves, which can be used as input into a cathodic protection model for calculating the number and size of sacrificial anodes required for successful cathodic protection of offshore steel structures.
