CATHODIC PROTECTION DESIGN

-External Corrosion Coating is a combination of both coating and anode.

ANODE
-In the event of coating damage or deterioration, a secondary anode system is also provided, typically in the form of zinc or aluminum alloy sacrificial bracelet anodes.
-Cathodic Protect design is based on DNV-RP-F103.
-The minimum required anode length corresponding to the selected anode bracelet thickness to meet both minimum weight and surface area requirement which is the thickness of anode must to be same as thickness of concrete coating
-Cathodic Protection design calculation as per below :
