Abstract
The application of cathodic protection (C.P.) to the bottoms of aboveground metallic storage tanks can be difficult and expensive. On large diameter tanks (over 30 ft. (9m)), distributed perimeter anodes do not usually supply enough current density to protect the center sections of tank bottoms. Some environments will not allow the installation of C.P. groundbeds which have been used effectively in other locations. Where space is limited, a small boring machine can be used to bore horizontal holes under tank floors. Anodes are installed in these holes, surrounded with petroleum coke breeze, and an effective, cost efficient system for providing cathodic protection current to the entire tank floor can be achieved.
