Facilities approaching the end of their economic or operating service life are a special case where _______________ can be very useful. The end of life case for plant operation is about gaining the maximum remaining economic benefit from an asset without undue personnel, environmental or financial risk:



The scope of an RBI assessment may vary between an entire refinery or plant and a single component within a single piece of equipment. Typically, RBI is done on multiple pieces of equipment (e.g. an entire process unit) rather than______________________:



If the scope of the RBI assessment is a multi-unit facility, the first step in the application of RBI is screening of entire process units to rank ____________:



It is often advantageous to group equipment within a process unit into ____________________ where common environmental operating conditions exist based on process chemistry, pressure and temperature, metallurgy, equipment design and operating history:



_________diagrams for the unit may be used to identify the systems including information about metallurgy, process conditions, credible damage mechanisms and historical problems:



In most plants, a large percentage of the total unit risk will be concentrated in a relatively small percentage of the____________________. These potential high-risk items should receive greater attention in the risk assessment:



When emergency systems (e.g. flare systems, emergency shutdown systems) are included in the RBI assessment, their service conditions during both ___________should be considered:



The purpose of establishing _______________is to 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____________________:



The normal operating conditions may be most easily provided if there is a process flow model or ____________________ available for the plant or process unit:



Codes and legal requirements vary from one ____________________to another:



An RBI assessment is a ______________________process:



From the understanding of ________________, an inspection program may be designed that optimizes the use of inspection and plant maintenance resources:



The results of managing and reducing risk are all of the following EXCEPT:



Reducing inspection costs is usually not the primary objective of an__________________, but it is frequently a side effect of optimization:



More effective infrequent inspections may be substituted for less effective frequent inspections:



RBI focuses efforts on areas where the ___________________risks exist :



Changing metallurgy of components can reduce ___________:



The objective of RBI is to direct management’s decision process of prioritizing resources to ______________________:



Reduce or limiting available inventories can reduce by what



Impending failure of pressure equipment is not avoided by inspection activities unless the inspection precipitates risk mitigation activities that change the ____________ :



The primary product of an RBI effort should be an _____________ for each equipment item evaluated:



An RBI assessment made on new equipment or a new project, while in the design stage, may yield important information on potential risks. This may allow potential risks to be __________ and have a risk-based inspection plan in place prior to actual installation:



For risks considered unacceptable, the plan should contain the mitigation actions that are recommended to reduce the ________________ to acceptable levels:



The Fitness-For-Service assessment is often accomplished through the knowledge and expertise of the inspector and engineers involved when deterioration is within 57. known acceptable limits, but on occasion will require an engineering analysis such as those contained in API_______:



Some risks cannot be adequately managed by inspection alone. Examples where inspection may not be sufficient to manage risks to acceptable levels are:



The risk-based inspection methodology is intended to complement other risk-based and safety initiatives. The output from several of these initiatives can provide input to the RBI effort, and RBI outputs may be used to improve safety and risk-based initiatives already implemented by organizations. Below are examples of some of these other initiatives EXCEPT the following :
