API RP 580 – Risk-Based Inspection, Third Edition

The purpose of this document is to provide users with the basic minimum and recommended elements for developing, implementing, and maintaining a risk-based inspection (RBI) program. It also provides guidance to owner-users, operators, and designers of pressure-containing equipment for developing and implementing an inspection program.

These guidelines include means for assessing an inspection program and its plan. The approach emphasizes safe and reliable operation through risk-prioritized inspection. A spectrum of complementary risk analysis approaches (qualitative through fully quantitative) can be considered as part of the inspection planning process.

a)understanding the design premise;

b)planning the RBI assessment;

c)data and information collection;

d)identifying damage mechanisms and failure modes;

e)assessing probability of failure (POF);

f)assessing consequence of failure (COF);

g)risk determination, assessment, and management;

h)risk management with inspection activities and process control;

i)other risk mitigation activities;

j)reassessment and updating;

k)roles, responsibilities, training, and qualifications;
