TRANSCRIPT
Risk based inspection (RBI) is a method in which assets
are identified for inspection based on their associated
risks as opposed to a predetermined fixed time interval.
A calculation of risk with the RBI and API (American
Petroleum Institute) involves determining the
probability of failure combined with its consequence.
The standard API RP 581 provides quantitative
procedures, which is based on Weibull analysis, to
establish an inspection program using risk-based
methods for pressurized fixed equipment, including
pressure vessel, piping, tankage, pressure relief devices
and heat exchanger tube bundles.
In Weibull analysis, also known as life data analysis, the
main objective is to predict the life of the equipment/
component in the population by fitting a statistical
distribution to life data from a representative sample of
units. The parameterized distribution for the failure
data set can then be used to estimate important life
characteristics of the product such as the probability of
failure at a specific time, the mean life and the failure
rate, to name a few. Weibull analysis has been included
in the new version of API 581 Risk-Based Inspection
Methodology, increasing the need to understand
Weibull analysis. This course presents an overview of
the basic concepts in Weibull analysis and how it is
being applied in API 581.
Upon completion of this course, participants will be able to:
Understand the concepts of Weibull analysis and how it is applied in API 581.
Describe the characteristics of Weibull distribution.
Apply the Weibull analysis to determine the probability of failure of Pressure Relief Device (PRD) and Heat Exchanger Tube Bundle.
