Cathodic Protection Annual Test Station Reading Log

Annual inspection log for recording pipe-to-soil potential readings at cathodic protection test stations and documenting whether the pipeline meets cathodic protection criteria, including deficiencies and corrective actions.

Inspection Details

• Inspection date and time recorded
• Pipeline, segment, and test station identified
  Record the pipeline name/ID, segment or milepost, and test station number or location.
• Inspector name and qualification documented
  Enter the inspector or technician name and any required qualification or certification reference.
• Weather and site conditions noted
  Document conditions that could affect readings, such as rain, frozen ground, standing water, or access limitations.
• Inspection scope confirmed as annual pipe-to-soil reading log
  Confirm this inspection is the annual cathodic protection test station reading log for the pipeline.
• Reference standard or SOP available
  Identify the applicable company procedure, corrosion control plan, or reference criteria used for the inspection.

Reference Electrode and Test Setup

• Reference electrode type verified
  Select the reference electrode used for the reading, such as copper/copper sulfate (CSE).
• Reference electrode condition acceptable
  Electrode is intact, clean, and suitable for use; no visible damage or contamination.
• Lead connections secure and test equipment functioning
  Meter, leads, and connections are secure, undamaged, and operating properly before taking readings.
• Test station access unobstructed
  Test station is accessible without unsafe excavation, traffic exposure, or physical obstruction.
• IR drop minimized or accounted for
  Reading method accounts for IR drop or uses an approved instant-off / depolarized method where required by procedure.

Pipe-to-Soil Potential Readings

• Instant-off pipe-to-soil potential reading
  Record the measured pipe-to-soil potential at the test station.
• Native or depolarized reading recorded when required
  Record any additional reading required by the procedure, such as native, polarized, or depolarized potential.
• Reading meets cathodic protection criterion
  Confirm the measured potential meets the applicable cathodic protection acceptance criterion used by the operator.
• Test station reading stable and repeatable
  Repeat reading is within expected tolerance and does not indicate a loose connection, interference, or unstable condition.
• Interference or stray current observed
  Indicate whether interference, stray current, or other abnormal conditions were observed during the reading.
• Photo of meter reading or test setup captured
  Attach a photo showing the meter reading, test station, or setup if required by site procedure.

Deficiencies and Corrective Actions

• Deficiencies identified
  Select any deficiencies or non-conformances observed during the inspection.
• Corrective action required
  Indicate whether follow-up action is needed to restore or verify cathodic protection performance.
• Corrective action description
  Describe the corrective action taken or recommended, including retest, repair, adjustment, or escalation.
• Retest scheduled or completed
  Record the date and time for a follow-up reading if required.

Sign-Off

• Inspection complete and records accurate
  Confirm all required readings, observations, and corrective actions are documented accurately.
• Inspector signature
• Supervisor or reviewer signature
