Risk Based Inspection
- Risk based inspection is the process of developing.
- The inspection frequency, methods employed
- The essential process is a risk analysis
The inspection of pressure plant, structures and machinery was once determined from custom industry practice based on prescriptive codes and health and safety legislation. The inspection frequency, methods employed and locations examined were determined by the type of equipment with little consideration given to its age, specific duty or likely damage. Increased operational experience and a greater appreciation of ageing and the hazards has led some parts of industry to adopt a more informed approach to inspection planning, specifying an inspection appropriate to manage the risk of failure within regulatory expectations.
Risk based inspection is the process of developing a scheme of inspection based on knowledge of the risk of failure. The essential process is a risk analysis. This is the combination of an assessment of the likelihood (probability) of failure due to flaws damage, deterioration or degradation with an assessment of the consequences of such failure.
