To provide participants with overview of cathodic protection system design.

Course Emphasis:-

• Protection potential; for stainless alloys.
• Impressed current system.
• Use of thermal sprayed aluminum - distribution of anodes.
• Protection of offshore pipelines.
• Monitoring and/or Inspection of CP performance.
• Current output from sacrificial anodes.
• Potential measurements.
• Internal Cathodic Protection in pipes: Introduction .

ý  Potential drop for current transport inside an insulated pipe.

ý  Potential drop inside a metal pipe with constant current density on the internal wall.

ý  Potential drop inside a pipe with actual polarization curves.
