The estimated period that an asset or component can continue to operate safely before reaching its limiting condition.
Remaining Life (RLIFE) is the estimated period during which an asset, component or equipment item can continue to perform its intended function safely and reliably before reaching a limiting condition requiring repair, replacement or retirement. Remaining life assessments consider degradation mechanisms, inspection results, operating conditions and engineering analyses to support asset integrity management and lifecycle planning.
Remaining Life estimates how long an asset can continue operating safely before repair, replacement or retirement becomes necessary.
Remaining Life is commonly estimated using corrosion rates, Fitness-for-Service assessments, inspection history and engineering analysis to support inspection planning and maintenance decision-making.
Remaining Life estimates the future serviceability of an asset, whereas Fitness-for-Service evaluates whether the asset is currently suitable for continued operation under specified conditions.
