Cathodic Protection Design (DNV-RP-B401 1983)

The Cathodic Protection Design (ANOD) module is used to design a bracelet anode system by helping the engineer to select an appropriate anode size and spacing along the pipeline. Alternatively, the module may be used to quickly check the validity of an existing or proposed design.

The ANOD module calculation method, default values and help screen information, are based primarily on Det Norske Veritas’ recommended practice for cathodic protection design (DNV RP B401, 1993).

• Calculate an overall heat transfer based on the internal area of a pipe if all the coatings have a specified thickness.
• Calculate the required thickness of a coating to produce a given heat transfer coefficient.

• Hydrate formation temperatures for a defined pressure range;
• Water dew point formation temperatures for a defined pressure range;
• Water content for a given dew point temperature and pressure.
