Risk based inspection is the process of developing an inspection plan based on knowledge of the risk of failure of the equipment. The essential element is a risk analysis. This is the combination of an assessment of the likelihood (probability) of failure due to damage, deterioration or degradation with an assessment of the consequences of such failure. The information gained from this process is used to identify (a) the type and rate of damage that may potentially be present and (b) the equipment or locations where failure would give rise to danger of different degrees.
Application of Risk Based Inspection (RBI)
Risk based inspection may be applied in any industry, but there has been most interest from the power and petrochemical sectors. The UK Health and Safety Executive has published a report on best practice for risk based inspection as a part of plant integrity management. TWI is currently leading a European Framework project called RISPECT whose aim is to develop a Risk-Based Expert System for Through-Life Ship Structural Inspection and Maintenance and New-Build Ship Structural Design.
Benefits
Risk Based Inspection (RBI) is a means of using inspection resources more cost effectively and with confidence. RBI ensures that you are complying with current safety regulations and also enables you to make inspection decisions based on adequate information and expertise and thereby saving time and money.
Using software for Risk Based Inspection (RBI)
As Risk Based Inspection involves a large amount of data using the right tools and software to process this information is crucial. TWI has developed RISKWISE, a new generation, code compliant software for optimising plant inspection and maintenance. RISKWISE can be customised to suit each company's individual needs and is available for the following areas:
