API 580 / API 581 — Risk-Based Inspection (RBI) for fixed equipment in the oil, gas and petrochemical industry

# API 580 / API 581 — Risk-Based Inspection (RBI) for fixed equipment in the oil, gas and petrochemical industry — 38% of in-scope requirements covered.

4 requirements · 4 in scope (2 designed · 2 advisory). The 38% is weighted over the in-scope base.

**Source:** API Recommended Practice 580 (RBI methodology) + API 581 (RBI quantitative technology) governing inspection planning for fixed equipment (vessels, piping, tanks) by probability × consequence of failure. KYE™ governs the authority and evidence of an AI-recommended inspect/repair/replace action and records the inspection-interval + failure-mode reference vocabulary; KYE™ does not compute the RBI probability or consequence. Starter requirement set (Wave-Ralph-Industrial); deepen by graft. · **License:** API recommended practices are copyrighted; KYE™ registry paraphrases each requirement's intent and cites the official identifier for mapping purposes only.
