An Integrity Assessment is a systematic engineering evaluation of an asset's condition using inspection results, design data, operating history, process conditions, degradation mechanisms and applicable engineering codes or standards to determine whether equipment remains fit for continued service. Assessments may include fitness-for-service evaluations, remaining life calculations, corrosion assessments, defect characterization, fracture mechanics, risk evaluations and comparisons against original design requirements. The objective is to establish whether the equipment can continue operating safely under its current service conditions, requires repair or replacement, or should be subject to revised operating limits or inspection intervals. Integrity Assessments are fundamental to risk-based asset management and provide the technical justification for engineering decisions affecting asset reliability, safety and regulatory compliance.
