Damage Assessment & FFS — Engineering Services
Fitness for Service (FFS)
API 579-1/ASME FFS-1 and BS 7910 fitness-for-service assessments for damaged or degraded pressure vessels, piping, tanks, and structural components — turning inspection findings into engineering decisions.
- —General and local metal loss assessment
- —Crack-like flaw assessment — fracture mechanics
- —Dent, gouge, and mechanical damage evaluation
- —Pitting corrosion assessment
- —Level 1, 2, and 3 assessment as appropriate
- —Remaining life and reassessment interval determination
Engineering Critical Assessment (ECA)
Fracture mechanics-based assessment of weld defects, crack-like indications, and planar flaws — determining acceptability under defined operating conditions per BS 7910, API 579, and CSA Z662.
- —Crack-like flaw acceptability — Failure Assessment Diagram (FAD)
- —Residual stress evaluation and sensitivity analysis
- —Material fracture toughness assessment
- —NDE sizing uncertainty integration
- —Pipeline girth weld flaw assessment
- —Fatigue crack growth analysis where applicable
Failure Investigation & Root Cause Analysis
Technical investigation of pressure equipment failures, weld failures, corrosion events, and integrity incidents — establishing root cause, contributing factors, and practical prevention recommendations.
- —Damage mechanism identification and analysis
- —Metallurgical review and materials assessment
- —Inspection and maintenance record review
- —Root cause and contributing factor analysis
- —Failure timeline reconstruction
- —Prevention and corrective action recommendations
Remaining Life & Life Extension
Quantitative remaining life assessment and life extension justification for ageing pressure equipment, piping, and pipeline assets — supporting continued operation beyond original design life.
- —Corrosion-based remaining life calculation
- —Fatigue and cyclic loading life assessment
- —Creep and high-temperature service evaluation
- —Probabilistic and deterministic assessment methods
- —Life extension strategy and documentation
- —Regulatory submission support
Anomaly Management
Structured anomaly management programs for pipeline and pressure equipment integrity — from detection through engineering assessment, disposition, tracking, and closure.
- —Anomaly classification and severity ranking
- —Engineering assessment and disposition
- —Immediate, monitored, and scheduled action plans
- —Anomaly database and tracking system support
- —Integration with PIMS, RBI, and IM programs
- —Repair vs. monitor decision documentation
