Estimating Measurement Performance With Truncated Data Sets

Paper No. IPC2022-87060

The API’s third edition of the 1163 Standard (2021) enhances ILI tool performance validation, focusing on Level 3 validation with real-world data. It addresses issues like truncation, where measurements below a threshold are not reported. This paper presents a model to estimate ILI tool performance despite truncation, validated through simulations and field data, improving pipeline integrity assessments and risk analyses.
