...Verification and validation are independent activities that are used together for checking that an ILI service meets requirements and performance specifications and that it fulfills its intended purpose. Verification is an internal process and it is intended to check that the ILI service meets...

...Abstract The performance of in-line inspection tools employed for integrity assessments has significant impact on the reliability of assessment results, the extent of required remediation, and justification of re-inspection intervals. Analytical methods for verification of assumed performance...

... and red flag verification regimes is also presented, and the methodology is argued to be a very powerful tool in life cycle corrosion management. risk based corrosion prediction modeling root cause critical corrosion mechanisms probability of failure consequences of failure corrosion failure non...

... verification via diligent on-line monitoring are identified. PERTINENT CONSIDERATIONS Attempts have been made to rationalize fitness for purpose, by examining bands of operability for identified critical parameters to quantify and drive risk-based performance. ² This may be done on a structure...
