Asset Lifecycle and Integrity
Integrity considerations from concept and design through operation, renewal and retirement.
What this topic covers
Integrity considerations from concept and design through operation, renewal and retirement.
Core ideas
Design decisions establish materials, loads, corrosion allowance, maintainability and inspection access.
Operating history changes the condition of assets through wear, corrosion, fatigue, fouling, thermal cycling and other mechanisms.
Retirement and replacement decisions should use condition, risk, obsolescence, reliability and future service needs—not age alone.
Program tradeoffs
A mature program does not inspect everything equally; it identifies credible degradation and prioritizes the assets where loss of function matters most.
What good evidence looks like
Data quality, asset identity and decision ownership are as important as the sensor or inspection method.
Lifecycle perspective
Lifecycle thinking links design, operation, maintenance, renewal and retirement rather than treating integrity as a late-life activity.
