What is the definition of Projected date calculations in the Analysis results?

Listed below are the definitions of some of the commonly used CIM Projected Dates columns found in the "Add Anomalies to Analysis" screen and the "Analysis Results" screen and export.

Projected Depth Condition Date

The date at which a given anomaly is projected to reach the “depth condition” threshold as defined by the “Metal Loss Percentage for Depth Condition” attribute in Integrity Compliance (default 80% WT)

Assessment End Date + (Metal Loss Percentage for Depth Condition - (Metal Loss Depth + Metal Loss Depth Tolerance)) / (Corrosion Growth Rate / Nominal Wall Thickness))

Projected Burst Condition Date

The date at which a given anomaly is projected to reach Modified B31G Burst Pressure = MOP, based on the pipe properties and operating pressure information configured during analysis.

Assessment End Date + ((ASME B31G Modified PBurst Remaining Wall to MOP - ((Metal Loss Depth + Metal Loss Depth Tolerance) * Nominal Wall Thickness)) / Corrosion Growth Rate)

Projected Safe Condition Date

The date at which a given anomaly is projected to reach Modified B31G Safe Pressure (i.e. Burst Pressure * Design Factor * Seam Factor), based on the pipe properties and operating pressure information configured during analysis.

Assessment End Date + ((ASME B31G Modified PSafe Remaining Wall to MOP - ((Metal Loss Depth + Metal Loss Depth Tolerance) * Nominal Wall Thickness)) / Corrosion Growth Rate)

Years to Re-inspection

For metal loss anomalies, the earliest of: Projected Depth Condition Date, Projected Safe Condition Date, Projected Girth Weld Condition Date (if applicable)

For crack-like anomalies: Projected Burst Condition Date based on Modified Log-Secant burst pressure model
