RBI assessments are a ______ process that requires proper skills and knowledge from multiple disciplines.
An RBI assessment should be undertaken with clear _____ and _____ that are fully understood by all members of the RBI team and by management.
objectives and goals
What are the results of managing and reducing risk?
Improved safety, avoided losses of containment, and avoided commercial losses.
Reducing inspection costs is usually not the primary objective of an RBI assessment, but it is frequently a side effect of optimization. True or false?
More effective, infrequent inspections may be substituted for less effective, frequent inspections. True or false?
RBI focuses efforts on areas where the greatest risk exist. True or false?
Some risks can be managed by actions other than inspection? What are some of those?
Change metallurgy of components to reduce POF, reduce or limit available inventories to reduce COF, remove unnecessary insulation to reduce probability of CUI, etc
RBI assessments made on new equipment or a new project, while in the design stage, may yield important information on potential risks. This may allow risks to be ______ by design.
Facilities approaching the end of their economic or operating service life are a special case where application or RBI can be very useful. Inspection activities that do not impact risk during the remaining life are usually ______?
Eliminated or reduced
Is it important to revisit the RBI assessment if the remaining plant life is extended after the remaining life strategy has been developed and implemented?
In multi-unit facilities, individual pieces of equipment should be selected as the first step of RBI?
No - first step in the application of RBI is screening of entire process units to rank relative risk.
________ for the unit may be used to identify the systems including information about metallurgy, process conditions, credible damage mechanisms, and historical problems.
Block flow or process flow diagrams
In most plants, a large percentage of the total unit risk will be concentrated in a relatively small percentage of the equipment items. These potential high-risk items should receive _______ attention in the risk assessment.
When emergency systems (Flare and emergency shutdown systems) are included in the RBI assessment, their service conditions during both routine operations and upset should be considered. True or false?
What is the importance of establishing operational boundaries?
Identify key process parameters that may impact deterioration.
Process conditions during start-up and shutdown can have a significant effect on the risk of a plant especially when they are more severe (likely to cause accelerated deterioration) than normal conditions, and as such should be considered for all equipment covered by the RBI assessment. A good example is:
