PURPOSE Flashcards
The purpose of this document is to provide users with the basic minimum and recommended elements for ,,,,
developing,
implementing, and
maintaining a RBI program
The approach (RBI) emphasizes safe and reliable operation through ,,,,,,
risk-prioritized inspection
A spectrum of complementary risk analysis approaches (,,,,,,,,) can be considered as part of the inspection planning process
qualitative through fully quantitative
The expected outcome from the application of the RBI process should be ,,,, ,,,,,.
the linkage of risks with appropriate inspection, process control, or other risk mitigation activities to manage the risks
The RBI process is capable of generating:
- a ranking by relative risk
- a detailed description of the inspection plan
- a description of any other risk mitigation activities
- the expected risk levels
- identification of risk drivers
General:
This RP contains both minimum program requirements to qualify ,,,,,,,
for interval extension beyond rule-based (1/2 life) requirements
&
provides additional suggested guidelines on using risk analysis to develop an effective RBI program
Work Process Requirements:
Work process requirements include the following:
- A documented management system
- Sufficient data shall be captured and maintained
- The basis for both the POF and COF shall be documented
- The various inputs used to assess both the POF and COF shall be captured
- The POF, COF, and risk results shall be captured in the documentation
Data Requirements:
Data inputs and assumptions shall be validated by qualified personnel such as ,,,,,, to review operating parameters used
process engineer/operator
Damage Mechanisms and Failure Modes:
The RBI team shall consult with a ,,,, to define the equipment damage mechanisms, damage modes (optional), and potential failure modes
corrosion specialist
Damage Mechanisms and Failure Mode
A qualified ,,,,, shall be responsible for assessing the types of damage mechanisms and their applicability and severity to the equipment
corrosion specialist
POF Analysis :
POF analysis requirements include the following:
- shall address all credible damage mechanisms
- evaluated to identify active and credible damage mechanisms
- determine the effectiveness in finding the identified mechanisms
COF Analysis:
COF analysis requirements include the following:
- estimate the consequences that are likely to occur due to a failure
- The major factors in evaluating the consequences of failure
Evaluation of Risk:
Risk shall be determined by combining the ,,,,
POF & COF (Risk = probability × consequence)
Evaluation of Risk:
Overall risk shall include the ,,,,,
probability of loss of containment
Output:
Output requirements include the following:
-Items with unacceptable risk to the owner-user
(In addition, higher risk items should also be prioritized)
-The inspection strategy shall be a documented
-Inspection results such as the identification of damage mechanisms
