Identifying Gaps in Risk Based Inspection Programs (RBI) That Impact Reliability

heater-tube-bundle
Risk based inspection (RBI) is a powerful tool to identify and manage mechanical integrity risks in fixed equipment and piping but is only one part of a robust reliability program.  RBI informs inspection decision making on where, when and how to inspect most of equipment but is frequently misinterpreted as a “Silver Bullet” that covers all necessary inspection activities in a refinery.  Most RBI programs have significant gaps that can result in costly reliability issues or unjustified maintenance costs.  RBI gaps can exist where risk assessments require input from outside of an inspection department or mechanical integrity group.  Examples of these gaps are when failures have process consequences but not mechanical integrity concerns, such as tube leaks in shell and tube heat exchangers and cyclones in an FCC Unit.  Another example is when mechanical integrity is dependent upon other systems functioning per design, such as fired heater tubes.  Quantitative RBI...

Risk-Based Work Selection (RBWS) – Choosing a Software Tool

software-tool-cover Choosing the right software tool for RBWS
Using the right software tool can save time and improve results of Risk Based Work Selection (RBWS) which is a standalone work process aimed at optimizing turnaround (TA) work scopes.  RBWS uses risk assessments to determine if individual worklist items are justified by Health, Safety, & Environmental Risks or Financial Risks.  Significant reductions in turnaround work scopes typically result from this structured work process. Becht Engineering has conducted RBWS sessions using a variety of tools ranging from Excel spreadsheets to our custom-built STRAITS Software.  Some tools have distinct advantages over others, so we wanted to highlight why a specialized tool should be used for RBWS and what are the key features to look for when selecting a tool.  Why is a Specialized Tool Needed? The information necessary to conduct an RBWS should already exist.  The challenge is digging the information out of desk drawers, databases, and excel spreadsheets, and organizing...

BIDES - A Knowledge Base Facilitating Effective RBI Assessments

BIDES - A Knowledge Base Facilitating Effective RBI Assessments
There are numerous challenges that Inspectors and Reliability Engineers face when developing Risk Based Asset Integrity Plans, such as: Identifying the applicable Damage Mechanisms Picking the correct Failure Mode(s) Determining the Probability of Failure Deciding how to mitigate risks to acceptable levels Industry documents give some guidance (i.e. API-571, API-580) but not the whole picture.  A new suite of Becht Documents clarifies where the industry documents leave off; giving the user a repeatable solution to these challenges.  We call these documents BIDES - B echt I nspection D evelopment and E xecution S trategies. What is BIDES? BIDES is a suite of 76 documents that lay the technical foundation for Damage Mechanism Reviews, Integrity Operating Windows (IOW), Turnaround Risk Based Work Selection (RBWS), and Equipment Reliability Plans (ERP).   Each element of the BIDES covers a specific damage mechanism.  The suite includes the 66 damage mechanisms listed in API-571 (including...
