Time is money.  Cathodic protection rectifiers are installed at extensive distances from neighboring rectifiers in an impressed current system.  In the past, this would require personnel to spend prolonged traveling time between the various locations just to access the unit.   Remote monitoring units with GPS interruption capabilities save the operator a substantial amount of time. At a glance, personnel can monitor the various operating parameters of a rectifier without even opening the cabinet. The operator receives notification of operating malfunctions or failures once one occurs.   This allows personnel to respond to outages and return the rectifier to normal operating condition. An internal interrupter allows the operator to cycle the rectifier without having to visit the unit.  Satellite synchronized interruption of all units facilitates annual surveys and assists in troubleshooting a cathodic

Cathodic Protection for Industrial Facilities

Industrial Plants

The annual cost of corrosion damage in the United States exceeds 230 billion dollars. Anyone responsible for maintaining production facilities at a large industrial plant is familiar with the cost of corrosion. The capital investment in structures exposed to corrosion makes preventative maintenance an economic necessity. Southern Cathodic Protection Company engineers are frequently called upon to evaluate the condition of metallic structures at locations being considered for purchase. The projected life expectancies of these structures can have significant impact on the value of the plant.

Cathodic Protection for Airports

Economy of operation, public safety and environmental protection are major concerns of airport operators. Solving corrosion problems is important to each of these goals. Southern Cathodic Protection Company engineers are involved in the design of new facilities to minimize the future effects of corrosion on the structures. Regardless of their size, civilian airports and military air bases have a number of underground structures where corrosion damage can severely impair service and safety. These include:

  • Fueling systems
  • Water and wastewater lines
  • Lighting and communication equipment
  • De-icing systems
  • Structural supports

Saltwater creates an extremely harsh environment challenging the corrosion engineer's innovation. Southern Cathodic Protection Company specialists have extensive experience insuring the productive life of a wide variety of structures subject to the ravages of the sea. Selection of construction materials and coatings are as critical as the cathodic protection systems designed for marine applications. Our design and installation services include systems for the following:

  • Docks & mooring facilities
  • Offshore drilling & production platforms
  • Subsea pipelines
  • Seaside retaining walls and piling

Underground Storage

Cathodic Protection for Underground Storage Tanks


Cathodic protection for underground storage tank

For UST OwnersAllow Southern Cathodic Protection Company to assist you in protecting your investment by preventing leaks and meeting state and federal regulations for underground storage tanks and piping.

Even without the strigent EPA regulations mandating corrosion control on underground storage tanks, a sound leak control program makes economic sense. Southern Cathodic Protection Company provides professional engineering services to assist tank owners in preventing leaks and achieving regulatory compliance.

These services include:

  • Corrosion Surveys to collect site specific information concerning soil characteristics, resistivity, electrical continuity, stray currents and interference.
  • Statistical Corrosion Probability (SCP) analysis for evaluating underground storage tank suitability for upgrading with cathodic protection in accordance with ASTM standards.
  • Testing

Above Ground Storage

Cathodic Protection for Above Ground Storage Tanks


For AST Owners And Operators


Increase facility design life and prevent environmental contamination with Southern Cathodic Protection Company corrosion engineering services.

As with UST's, safety and environmental regulations may require corrosion control for aboveground fuel storage tanks and associated piping in contact with an electrolyte. While material selection and protective coatings are prudent steps in preventing leaks on surfaces exposed to the atmosphere, cathodic protection has proven to be an effective and economical method for controlling corrosion on tank bottoms and underground piping.

Our staff of corrosion engineers provides the following services:

  • Cathodic Protection Design utilizing impressed current and galvanic systems.
  • Installation and Certification of systems by qualified employees of Southern Cathodic Protection Company.
  • Installation Supervision with on-site technical assistance from

Cathodic Protection for Water Towers & Water Facilities

Cathodic Protection for Water Storage Tanks

Cathodic protection is a standard, cost-effective, accepted method to prevent corrosion of the submerged surface inside steel water storage tanks. Cathodic protection systems for water storage tanks are almost always impressed current systems. Technical and economic reasons dictate that galvanic anodes almost never be used to protect a water storage tank.

Design Considerations

Design of a cathodic protection system for a steel water storage tank is normally controlled by the following four considerations.

  • Current Requirements for Protection
  • Water Resistivity
  • Geometry of Structure
  • Anode Service Life

If anode design provides a uniform distribution of current, then the current requirement for protection of a water storage tank is calculated by multiplying total surface area by a predetermined current density. Although many factors can influence current density, the

Southern Cathodic Protection Company (SCPC) has demonstrated experience in virtually all aspects of AC Mitigation and Modeling. When underground pipelines are near high voltage overhead transmission lines an electromagnetic field is created by the alternating current.  AC voltage may be induced in the pipeline which can cause coating damage, safety issues and or corrosion.  Southern Cathodic Protection has the expertise to detect AC interference and the modeling software to design mitigation systems.
Statistical Corrosion AnalysisForPipeline Asset Management Southern Cathodic Protection Company offers professional corrosion engineering services to perform a statistical corrosion analysis of cast iron, ductile iron and bare steel pipelines. The Southern Cathodic Protection Statistical Corrosion Probability (SCP™) and Maximum Pit Depth (MPD ™) models calculate mean-time to corrosion failure as well as maximum pit depths of the pipeline based on the age of the pipeline and the environment. The proprietary models are powerful tools in projecting the operating life of pipelines. These projections are critical elements for asset management and capital planning.
