Cathodic Protection

Cathodic Protection is a corrosion control technique used to protect buried or submerged metallic structures by reducing or eliminating electrochemical corrosion reactions. This service involves the design, evaluation, and optimization of cathodic protection systems to ensure effective long-term protection of critical assets.

Cathodic protection is commonly applied to pipelines, storage tanks, marine structures, and underground installations where corrosion risk is high.

Why Cathodic Protection Is Required

Metallic structures exposed to soil, water, or aggressive environments are susceptible to corrosion. Cathodic protection helps address challenges such as:

• Corrosion of buried and submerged assets

• Loss of wall thickness and structural integrity

• Leaks and environmental incidents

• Inadequate performance of existing protection systems

• Regulatory and safety compliance requirements

Properly designed cathodic protection significantly extends asset life.

Scope of Cathodic Protection Services

Cathodic protection services typically include:

• Design of cathodic protection systems

• Evaluation of existing CP system performance

• Troubleshooting and optimization

• Monitoring and performance assessment

• Documentation and compliance support

Both sacrificial anode and impressed current systems are addressed.
