API 580 Flash Cards

API 580 Flash Cards RBI will not compensate for these 6 things: 1. Inaccurate or missing information 2. Inadequate designs or faulty equipment installation 3. Operation outside the acceptable IOW's 4. Not effectively executing the plans 5. Lack of qualified personnel or teamwork 6. Lack of sound engineering or operational judgment RBI is specifically targeted for what industry? Hydrocarbon and chemical process. Mechanical Integrity Focused The RBI process is focused on maintaining the MI of pressure equip. items & minimizing the risk of loss of containment due to deterioration. RBI is not a substitute for a PHA or hazard and operability assessment (HAZOP). RBI compliments the PHA by focusing on the MI related damage mechanisms & risk management through inspection. What types of equipment is covered by RBI? 1. Pressure vessels 2. Process piping 3. Storage tanks 4. Rotating equipment (pressure side) 5. Boilers and heaters 6. Heat exchangers (shells, floating heads, channels & bundles) 7. Pressure-relief devices What equipment is not covered by RBI? 1. Instrument and control systems 2. Electrical systems 3. Structural systems 4. Machinery components (except pump and compressor casings) Who is the Target Audience for API 580? Inspection and engineering personnel who are responsible for the equipment covered by 580. Absolute Risk An ideal and accurate description and quantification of risk. Consequence An outcome from an event. There may be one or more consequences from an event. Consequences may range from positive to negative. However, consequences are always negative for safety aspects. Consequences may be expressed qualitatively or quantitatively. Damage Mode Ways that the damage mechanism may manifest itself. For example, the damage mechanism "corrosion under insulation" may precipitate a damage mode of either generalized corrosion or localized corrosion. Generalized corrosion could result in a large burst while localized corrosion might be more likely to result in a pinhole type Risk-Based Inspection A risk assessment and management process that is focused on loss of containment of pressurized equipment in processing facilities, due to material determination. These risks are managed primarily through equipment inspection. Risk Estimation Process used to assign values to the probability and consequence of a risk. Risk estimation may consider cost, benefits, stakeholders concerns and other variables, as appropriate for risk evaluation. Event Occurrence of a particular set of circumstances. The event may be certain or uncertain. The event can be singular or multiple. The probability of an event occurring within a given period of time can be estimated. External Event 4.1.16 External Event Events resulting from forces of nature, acts of god, sabotage, or events such as neighboring fires or explosions, terrorism, neighboring hazardous material releases, electrical power failures, forces of nature, and intrusions of external transportation vehicles, such as aircraft, ships, trains, trucks, or automobiles. HAZOP (Hazard And Operability Study A HAZOP study is a form of failure modes & effects analysis (FMEA). HAZOP studies, which were originally developed for the process industry, use systematic techniques to identify hazards & operability issues throughout an entire facility Reassessment The process of integrating inspection data or other changes into the risk analysis. RELATIVE RISK The comparative risk of a facility, process unit, system, Equipment item or component to other facilities, process units, systems, equipment items, or components, respectively. RESIDUAL RISK The risk remaining after risk mitigation. RISK Combination of the probability of an event and its consequence. In some situations, risk is a deviation for the expected Risk Acceptance A decision to accept risk. Risk acceptance depends on risk criteria Risk Analysis Systematic use of information to identify sources and to estimate the risk. Risk analysis provides a basis for risk evaluation, risk mitigation and risk acceptance. Information can include historical data, theoretical analysis, informed opinions and concerns of stakeholders. Risk Assessment Overall process of risk analysis and risk evaluation. Risk Avoidance Decision not to become involved in, or action to withdraw from a situation. The decision may be taken based on the result of risk evaluation. Risk Communication Exchange or sharing of information about risk between the decision maker and other stakeholders. The information may relate to the existence, nature, form, probability, severity, acceptance, mitigation or other aspects of risk. Risk Criteria Terms of reference by which the significance of risk is assessed. Risk criteria may include associated cost and benefits, legal and statutory requirements, socioeconomic and environmental aspects, concerns of stakeholders, priorities and other inputs to the assessment. Risk Driver An item affecting either the probability, consequence, or both such that it constitutes a significant portion of the risk.
