TankGard, the only system of its kind, is able to provide reliable CP for up to 10 years.
The TankGard impressed-current tank cathodic protection system was developed by Deepwater in the mid-1980s specifically to address harsh-environment upstream-process tanks and vessels. The systems were pioneered in the San Joaquin Valley oilfields of California, where produced water is hot and sour and systems have a high tendency for scaling and sludging. Deepwater installed several prototype systems to evaluate all combinations of anodes and reference electrodes. The result was a reliable, low-cost system that has a proven 10-year design life.
