COMMON IMPRESSED CURRENT CATHODIC PROTECTION APPLICATIONS
The following provides examples of various ICCP systems that are implemented on port infrastructure to provide corrosion mitigation.
ICCP can take many forms and be implemented on a wide variety of structures.
This section is to give the reader an overview of the common types.
Typically, ICCP systems have an intended service life of over 30 years.
Often suppliers of ICCP anodes will indicate that an ICCP system can have a service life of over 50 years.
While it is true that the ICCP anodes can be durable for 50 years with a constant flow of current, the electronics and wiring associated with the ICCP system typically do not have such a long service life.
For an owner to get 50 years out of an ICCP system it would require regular monitoring and maintenance of the system, as well as replacement of the T/R and other components as they deteriorate.
ICCP anodes are designed to be dimensionally stable while they deliver current over a long service life.
Dimensionally stable means that they will not significantly corrode.
The two most common types of ICCP anodes for port applications are titanium coated in a mixed metal oxide (MMO) and a cast silicon iron anode.
Each of the presented applications for ICCP provided below can implement either the titanium MMO or silicon iron anodes.
