Risk Strategies for Pressure Retaining Equipment
by Michael Hurley, 7/11/2024
Tags: API 580 API 581 Damage Mechanisms Mechanical Integrity Risk Based Inspection
What are equipment/inspection strategies in relation to mechanical integrity (MI) and risk based inspection (RBI)? It is a simple answer, but can be complicated to produce a documented set. API RP 581 has gone as far as the RAGAGEP can go since it is up to the Owner/User to define them as they are responsible for their risk. Knowing strategy/effectiveness tables are likely to be used without modification therefore AOC created a set that can be used as inspection recommendations out of the box.

Guidelines for Providing Process Conditions for RBI - Part 7: Environmentally Assisted Cracking and RBI
by James Leonard, 9/1/2019
Tags: Damage Mechanisms Data Collection Risk Based Inspection
The 7th installment in our series covers environmental cracking. James Leonard, RBI Team Leader, discusses the additional process data that may be needed to determine environmental cracking damage potential when environment, stress, and metallurgy are so alligned so as to indicate susceptibility to this damage mechanism.
Guidelines for Providing Process Conditions for RBI - Part 6: High Temperature Hydrogen Attack (HTHA)
by Vibha Zaman, 8/26/2019
Tags: Damage Mechanisms Data Collection Risk Based Inspection
Gathering adequate process data to determine HTHA susceptibility is sometimes a difficult and time consuming task. Therefore a simple screening can be performed to determine if more detailed process data is required. Senior Corrosion Specialist, Vibha Zaman, discusses the screening process and what factors to consider when more data is required.
Guidelines for Providing Process Conditions for RBI - Part 4: High Temperature Damage Mechanisms
by Leomar Penuela, 5/7/2019
Tags: Damage Mechanisms Probability Risk Based Inspection
In this fourth, of our eight-part series covering various guidelines for providing process conditions for Risk Based Inspection (RBI), a senior corrosion specialist discusses two groups of damage mechanisms that can result from high temperatures. We note that the standard inputs to your RBI software are not always sufficient to capture these damage mechanisms and provide some additional guidelines to take into consideration.
