RBI Program Management Flashcards

What is the recommended frequency for updating an RBI assessment?

Answer: When significant changes occur or at least every 5 years

RBI assessments should be updated when inspection results reveal new information, after process changes, when damage rates change significantly, or at a maximum interval of approximately 5 years to remain current.

Who should be part of an RBI assessment team?

Answer: A multidisciplinary team including inspection, process, materials, and operations personnel

API 580 recommends a multidisciplinary team that brings together expertise in inspection, corrosion/materials engineering, process engineering, and operations to ensure comprehensive risk evaluation.

What documentation is required to support an RBI program?

Answer: Equipment data, inspection history, process conditions, damage mechanism assessments, and risk rankings

A robust RBI program requires comprehensive documentation including equipment design data, operating conditions, inspection history and results, damage mechanism assessments, risk calculations, and inspection plans.

How should inspection effectiveness be classified in an RBI program?

Answer: By categories from highly effective (A) to ineffective (E) based on the probability of detecting specific damage

API 581 classifies inspection effectiveness from A (highly effective with high probability of detecting damage) through E (ineffective), based on the method's ability to detect and quantify specific damage mechanisms.

What is a mitigation action in the context of RBI?

Answer: Any action taken to reduce the risk of equipment failure to an acceptable level

Mitigation actions include targeted inspections, process changes, material upgrades, applying protective coatings, installing monitoring systems, or operational modifications that reduce either the probability or consequence of failure.

What key performance indicators (KPIs) should be tracked for an RBI program?

Answer: Unplanned failures, inspection findings versus predictions, risk reduction achieved, and cost savings

Effective RBI programs track KPIs such as unplanned failure rates, accuracy of damage predictions versus actual findings, overall risk reduction, cost savings from optimized inspection, and inspection plan adherence.
