Risk Based Inspection (RBI) management


Risk Based Inspection (RBI) management

The ability to plan maintenance activities and prevent unplanned plant shutdowns is crucial for the profitability and security of your industrial systems. Risk Based Inspection (RBI) is a methodology for inspection planning, with the purpose of optimizing inspections of your equipment.

The RBI methodology improves the running costs as well as the availability of your plant. Safety is also improved since the inspection intervals are set based on detailed analysis of the actual conditions at each individual plant. That is why an increasing number of companies, within different branches, recommend RBI as the basis for inspection planning.

A RBI analysis implies a systematic survey of the plant and comprises detailed analysis of damage mechanisms, consequence analysis and evaluation of inspection methods. For each component the probability and consequence of failure is analysed, with respect to safety and financial impact, and the inspection interval is set based on the level of risk.

Benefits of using RBI

The cost benefits of RBI are potentially extensive, regarding both direct and indirect costs. A RBI analysis gives the following results:

  1. Your plant and operations are safer with reduced number of
  2. Improved availability by identification of, and shortening of, inspection intervals for high risk items
  3. Extended inspection intervals for low risk equipment
