– The process will require the operation centers to determine these locations of Suspected Areas and/or Areas of “Active Corrosion”.

– Communication and Training with Leakage department is required for the personnel to have the complete understanding of sites that meets the criteria or definition.

– Leakage department will be require to review each DPI created for any candidates of Active Corrosion based on the definition, and therefore communicates to the operational center reporting FOL.

– If the FOL is in agreement to the initial assessment, then the segment shall be documented onto the Suspected Area of “Active Corrosion” log book as the first step.

– The item will be discussed on the Semi-annual meeting Decision to be made whether item(s) to be upgrade to “Active

Corrosion” status by a group consensus

Repair Corrosion LeaksRepair Corrosion Leaks– The process will require the operation centers to determine the

locations of Suspected Areas and/or Areas of “Active Corrosion”– All executed DPI’s shall be review by the designated operations

pending or completed DPI’s in the same general area– If by historical review of data appear to meet the criteria of Areas of

“Active Corrosion”, then the segments shall be placed in “Suspected Area of “Active Corrosion Log” and review at the Semi-Annual meeting
