API 580 study plan

Define risk, probability of failure, consequence of failure, and risk-based inspection in your own words and map each definition onto the RBI assessment workflow.

Distinguish qualitative, semi-quantitative, and quantitative probability-of-failure approaches and state the conditions under which each is appropriate.

Decompose the probability-of-failure calculation into generic failure frequency, damage factor, and management systems factor, and explain how each term is adjusted.

Describe how damage state (active, inactive, failed, or no damage) and inspection effectiveness combine to modify the damage factor.

Calculate damage factors for thinning, cracking, and mechanical or other mechanisms using susceptibility and severity inputs.

Rank inspection effectiveness categories on a scale and predict the resulting damage factor change for a specified mechanism.

Classify consequences into safety/health, environmental, and economic/business interruption categories and assign a category level to each.

Estimate consequence magnitude from release characteristics (flammability, toxicity, inventory, operating conditions) and state the assumptions that drive the estimate.

Combine probability and consequence results into a single risk value and locate it on a risk matrix.

Compare computed risk against defined risk acceptance criteria and classify each item as acceptable, tolerable with ALARP demonstration, or unacceptable.

Rank a mixed equipment population by risk and justify the prioritization order in writing.

Explain how risk drivers differ within the same risk rank and why that changes the response.

Identify the data categories the assessment requires: design, operating, inspection and test history, damage mechanism, failure and leak history, and management systems.

Evaluate data quality and record a documented assumption wherever data are missing or unreliable.

Trace how a single data error or gap propagates into the probability or consequence result and describe the validation step that would catch it.

Explain how the approved risk ranking drives inspection allocation and resource decisions.

Write assessment objectives that are explicitly tied to the owner-user's risk management goals.

Define scope and boundaries (equipment, systems, operating modes, time horizon) and justify each exclusion.

Assemble a team roster with the competencies each role requires and assign assessment responsibilities.

Set the assessment schedule, resource estimate, and measurable success criteria.

Select inspection methods and coverage for the top-ranked damage mechanisms and justify the inspection effectiveness level chosen.

Convert the risk ranking into a dated inspection plan with tasks, methods, coverage, and intervals.

Explain how inspection reduces probability of failure and why it does not change consequence of failure.

Describe how inspection findings feed back into the damage factor and the next reassessment.

List non-inspection mitigation options (repair, re-rate or derate, coatings and linings, inhibitors, process and operating changes, leak detection, isolation) and match each to a specific risk driver.

Determine whether each mitigation changes probability, consequence, or both, and estimate the residual risk after implementation.

Describe the roles and responsibilities of the owner-user, inspection personnel, engineers, and management across the assessment lifecycle.

State the qualifications and training required for assessment team members and how competence is maintained and verified.

Define reassessment intervals and the triggers that require an out-of-cycle update, including management of change, inspection findings, failures, and operating changes.

Document the assessment so that results, assumptions, inputs, and decisions are traceable and auditable.

Identify the records to be retained, the retention period, and who is accountable for them.

Complete a full-length timed practice exam and close every identified knowledge gap.
