A hybrid impressed current and galvanic cathodic protection system
This paper outlines the design and installation of a cathodic protection (CP) system for the support pilings and beams for a commercial building situated over brackish water. The CP system is comprised of an impressed current expanded titanium jacket system for the pilings and a galvanic thermally sprayed (metalized) zinc system for the beams. The impressed current CP system is powered and controlled via a distributed rectifier system (DRS). The DRS consists of an array of local rectifier units (LRU'S). Each of the LRU'S possess 10 channels which may be configured as outputs or inputs depending on the system design. All of the DRS control and monitoring operations are carried out digitally using a PC. The scope of this document includes background information, system design, system description, and energizing procedures.
