Remaining Life Analysis

Calculation of remaining safe operating life for equipment subject to corrosion, erosion, creep, fatigue, or other time-dependent damage mechanisms — supporting run-or-replace decisions, inspection interval setting, and capital planning.

Remaining life analysis determines how long equipment can continue to operate safely under current or projected conditions before reaching minimum required thickness, critical flaw size, or end-of-life criteria. TES Canada performs remaining life calculations for equipment subject to general corrosion, localised corrosion, erosion, high-temperature creep, fatigue, and other progressive damage mechanisms.

Analysis is based on measured condition data — typically from thickness surveys, inspection reports, or online monitoring — combined with applicable corrosion rate assumptions, design parameters, and operating conditions. TES Canada applies the calculation methods defined in API 579-1/ASME FFS-1 and relevant equipment codes such as API 510, API 570, and API 653, ensuring that remaining life estimates are technically defensible and traceable.

The output supports critical asset management decisions including inspection interval determination, turnaround planning, repair-versus-replace evaluation, and long-term capital expenditure forecasting. Remaining life analysis is particularly valuable for ageing equipment where original design margins have been consumed and operators need a clear, quantified basis for continued operation.
