TankGard™
Cathodic protection system for process vessels and tanks
TankGard is the only system of its kind, able to provide reliable CP to tank systems for up to 10 years.
The TankGard impressed current tank cathodic protection system was developed by Deepwater in the mid-1980’s 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 was hot and sour, and the systems had a high tendency for scaling and sludging. Deepwater installed several proto-type systems in which all combinations of anodes and reference electrodes were evaluated. The result was a reliable low-cost system that has proven to last the 10-year design life.
A the heart of the system is the innovative FlangeMate anode-mount; this system isolates the impressed current anode from the vessel within the mount, and eliminates spark hazards from insulated flange or Victaulic mounts. The Polatrak HP-1Z™ and RT-1Z™ reference electrodes coupled with an IR free potentially controlled power unit complete the system.

Key design points
Sustainable protection
TankGard systems have a 10 year life; many of these vessels can expect less than one (1) year using traditional sacrificial anodes.
Proven design for harsh conditions
TankGard is very well established product, with a long history of success. This proves especially valuable when retrofitting tank cathodic protection in oilfield brines with high H2S and CO2, with temperatures up to 200°F.
Self adjusting
The cathodic protection rectifier is controlled by the potential measurement taken in real-time, so the amount of protection is always automatically adjusting to the correct level.
