Close Interval Potential Survey (CIPS)

• ✔ Evaluates CP effectiveness along the pipeline
• ✔ Identifies areas of under-protection or over-protection
• ✔ Provides real-time data for system adjustments

Direct Current Voltage Gradient (DCVG) Survey

• ✔ Detects coating defects & pinpoint corrosion hotspots
• ✔ Measures voltage gradients to assess coating conditions
• ✔ Determines the severity of coating damage

Alternating Current Voltage Gradient (ACVG) Survey

• ✔ Identifies coating flaws & discontinuities
• ✔ Detects pipeline defects that may lead to corrosion
• ✔ Helps in prioritizing coating repairs

Current Attenuation Test (CAT) Survey

• ✔ Assesses CP system performance & coating integrity
• ✔ Identifies variations in pipeline current flow
• ✔ Detects discontinuities in cathodic protection coverage

Coating Conductance Survey

• ✔ Evaluates the effectiveness of external coatings
• ✔ Identifies degraded coatings needing maintenance
• ✔ Ensures long-term corrosion prevention

AC & DC Interference Studies

• ✔ Identifies stray current interference from nearby power lines, railways, or foreign pipelines
• ✔ Recommends mitigation measures such as zinc ribbon grounding or solid-state decouplers
