Human factors, inspection effectiveness, and RBI all play an important role in running an effective asset management program. This article discusses how each is applicable to inspecting equipment in processing facilities.
September/October 2016 Inspectioneering Journal
Risk-based inspection (RBI) programs and processes are front and center, both as a challenge to get it right, and as an integral tool and process to help us achieve success in risk management and equipment reliability. It has to be implemented, maintained, sustained, and in a state of continuous improvement over time in order to achieve the desired results.
July 15, 2016 By Greg Alvarado at Inspectioneering Journal
Anyone who knows me knows that Risk Based Inspection (RBI) and Risk Management are true passions of mine. I have dedicated much of my career to studying them, understanding their intricacies, and witnessing the benefits of their successful implementation. This article briefly discusses the history of RBI and provides a short, yet persuasive justification for investing in establishing an effective RBI program.
January/February 2016 Inspectioneering Journal
The enormous decline in oil prices over the past 14 months has definitely slowed projects and changed the energy and production landscape. Despite this, refineries, petrochemical plants, and chemical facilities must continue to run safely, responsibly, and reliably.
July/August 2015 Inspectioneering Journal
Asset managers need to know when repairs and replacement are required for many reasons, including safe operation, accurate budgeting, replacement planning, and on-going reliability. When predicting design life based on a simple, linear corrosion rate versus remaining thickness, metallurgical degradation, or crack propagation rates are often not accurate or realistic. Even if the models are good, things change.

Now that the stage has been set (via parts 1 and 2 of this series), let’s see what we can do to improve the efficiencies and effectiveness of the work execution processes through situation awareness. Who knows? Maybe even cut a few days off the turnaround in the process.
September 18, 2014 By Greg Alvarado at Inspectioneering Journal
This blog post is the second in a series about situation awareness (SA). The first part of this series introduced SA (defined as the gathering and utilization of data in real time and using it to improve work processes) and introduced an example of how real-time SA can be applied to plant turnarounds to better achieve your turnaround objectives.
August 25, 2014 By Greg Alvarado at Inspectioneering Journal
After spending decades in plants and assisting operators in developing mechanical integrity programs, something has become very apparent to me; owner-operators face serious challenges with situation awareness (SA). What do I mean by SA?

AE monitoring has been done for HIC affected vessels, with limited success. The limitation, which greatly affects the confidence level of results, is that traditional AE testing stresses, i.e. Kaiser affect overpressure and felicity effect types of re-stressing do not generate the types of stress necessary to generate elastic strain waves at the HIC laminar crack tips.

It is with sadness that I learned of the passing of one of the world’s greatest authorities on chemical process safety, Dr. Trevor Kletz; a man I deeply respected and admired for his commitment to improving safety, preventing accidents, and saving lives. Although I never met Dr. Kletz, I certainly wish I had. He was a pioneer in the discipline of process safety management, and had the courage and conviction to speak up about industrial shortcomings at times when others would not. He wrote and spoke candidly on causes of industry incidents and provided insight on how to prevent them...

We’ve been discussing Scalable Accuracy and its use related to Lifecycle Management technologies available to owner/operators. The last few topics have included Fitness for Service using Scalable Accuracy, the approach for Equipment Lifecycle Management and, to lay the foundation for proper thinking, making the case for Scalable Accuracy. In a continuation on the topic, this week’s blog will cover Risk-Based Inspection (RBI).
August 26, 2013 By Greg Alvarado at Inspectioneering Journal
This blog post continues our discussion from the previous posts on scalable accuracy. We started with a post outlining the steps prior to using scalable accuracy. Then we walked through the scalable accuracy approach to Fixed Equipment LCM. While I normally start with RBI when discussing scalable accuracy, it will be easier to use an example of Fitness for Service as our starting point.

April 29, 2013 By Greg Alvarado at Inspectioneering Journal
This is my second of three posts on Key Performance Indicators (KPIs) based on requests and discussions on the issue. In part 1 of this series I provided a brief overview of KPIs and their ability to predict good, poor, and sometimes dangerous performance in our quests to achieve certain objectives and goals.
April 22, 2013 By Greg Alvarado at Inspectioneering Journal
Requests for key performance indicators (KPIs) related to equipment integrity management programs have appeared on Inspectioneering’s LinkedIn group discussion as well as other industry forums. It also came up numerous times at the recent API Inspection Summit. Three of my blog posts this month will cover this subject.
March 18, 2013 By Greg Alvarado at Inspectioneering Journal
Over the years I have seen many initiatives go awry because the buyer listened to rumors and innuendo instead of doing a good job of due diligence. Or maybe they were just looking for what was easy as opposed to what was right. Ultimately, for most owners and operators, you are responsible for the sound basis and whether or not your approaches are defensible. It is up to you to do a thorough job of due diligence.
March 3, 2013 By Greg Alvarado at Inspectioneering Journal
This is a question with which I frequently like to start the API RBI 580/581 training course when I am instructing. It is meant to provoke the attendees to really think hard about why they order an inspection or really think about inspection strategies.
March/April 2013 Inspectioneering Journal

In response to reader feedback, we implemented some important improvements in 2012. As we broaden our scope to include all aspects of Asset Integrity Management, its synergy and leverage become increasingly important. We will sustain this forward movement in 2013 by continuously seeking ways to serve the Inspectioneering community at maximum value, as you will see by the comprehensive Inspectioneering client survey soon to launch.
July/August 2012 Inspectioneering Journal
The question of how to set risk targets is a logical one and should be addressed prior to or in the very early stages of RBI implementation. This article will guide readers through the basic elements required to address this question within an organization, as all companies do not have the same risk philosophy and can adapt these elements to fit their own.
May/June 2012 Inspectioneering Journal
Development of shale requires the utilization of numerous types of fixed equipment. Due to the high cost and risk associated with hydrocarbon production and processing, E&Ps must continue to manage cost-effective and safe fixed equipment programs. Are the fixed equipment integrity management challenges related to shale development different from the current challenges faced in the upstream oil and gas business?
January/February 2012 Inspectioneering Journal
The various factors of the challenge, e.g. creating effective and then efficient inspection strategies, are at the crux of the decision process. Within each of these factors are questions that must be answered. The answers should be well thought through and provided as part of your risk-based inspection analysis process.
November/December 2011 Inspectioneering Journal
The original article on scalable accuracy which laid the groundwork for the concept was published in the March April 2011 issue of the Inspectioneering Journal, entitled Scalable Accuracy, Key Roles of Risk Based Inspection and Fitness for Service, Equipment Life-Cycle Management Process. This article is reprinted immediately following this article for ease of reference. The two examples touched upon in the original article were the fitness for service approach as represented by the joint API ASME standard, API 579-1/ASME FFS-1 Fitness for Service Standard and the API Recommended Practice 581, representing the specific API RBI technology.

It is important to preserve as accurate an account as possible if we are to learn from the past. I believe it is important to protect ourselves from ourselves from rationalizing the past to justify movement toward "rationalization of abnormalities", as explained by Mr. Don Holmstrom from the US CSB, appearing in paragraph 21 of the copy of the presentation given by the US Chemical Safety Board to the BP Independent Panel, headed by James A. Baker III, former US Secretary of State. This presentation immediately follows this article. Each paragraph is numbered. These paragraphs will serve as references further in this editorial.

Over the past 18 years of serious RBI involvement, it has become clear to me that there are certain hurdles, that when "cleared", have paved the way to jurisdictional acceptance of RBI (and fitness for service, for that matter). This article will cover many of these "steps", not all as they are numerous, that have lead to success in some of the "toughest" jurisdictions in the US and the world. On your marks, get set, here we go....

In my travels around the world as one of the primary API RBI 580/581 training course instructors the question always comes up, “What risk threshold or tolerable risk should I be using?” and “If I do not have one, how can I implement RBI?”
May/June 2007 Inspectioneering Journal
This is part 2 in a multi-part series. Part 1 set the stage in explaining the basics of RBI. As I am most familiar with API Base Resource Document 581, I will continue to use this technical basis for this article.
March/April 2007 Inspectioneering Journal
An earlier version of this updated article appeared in the January-February 1998 issue of the Inspectioneering Journal. It is hard to believe that nine years have passed so quickly. Fortunately the industry, as a whole, has learned much and technologies have advanced, in the interim. Unfortunately, in that time period plant infrastructures have aged and equipment has failed, sometimes with catastrophic results. Some failures were directly attributable to damage mechanisms and fixed equipment reliability program weaknesses. Often times related, we have seen, what appears to be breakdown in management systems, in refineries, chemical plants and exploration and production areas that lead or contributed to or enabled equipment failure 1, 2, 3 . On the other hand, organizations like the API (American Petroleum Institute) RBI User Group, API RP 579 Fitness for Service Committee, API Subcommittees on Inspection and Corrosion and Materials continue to move forward, desiring and acting to improve the effectiveness of fixed equipment reliability programs via implementation of sound risk based inspection technology and the creation of excellent supporting reference documents like API RP 571 on damage mechanisms. These committees continue to improve their codes and respective reference documents as do other organizations in various countries, such as NACE, EU CEN documents, the HSE, ABSA (the Alberta Boiler Safety Association), ASME, Australian authorities, the state of California and others too numerous to list.

The Shell Martinez Refinery has been in operation since 1915, and is located 30 miles northeast of San Francisco on about 1,000 acres of land. The refinery combines state-of-the-art facilities and equipment to convert approximately 165,000 barrels of crude oil a day into many products including automotive gasoline, jet fuel, diesel, petroleum coke, industrial fuel oils, liquefied petroleum gas, asphalt, sulfur, and lubricants. The Shell Martinez Refinery has grown into a sprawling yet efficient assemblage of sophisticated processing equipment; modern control rooms; environmental protection facilities; shipping and receiving terminals for marine, rail, and truck cargoes; maintenance shops; office buildings; quality assurance laboratories; storage tanks; and warehouses. In some ways it resembles a small city with its own utilities, medical facilities, and fire department.

The "low hanging fruit" has been harvested in most places. Now comes the challenge of gathering the most bountiful harvest, that which is amongst the leaves and branches, without harming the tree. This will require practical expertise. This will require computational models that narrow the scatter band and are more accurate that are asking the right questions (which requires practical knowledge, technical knowledge and experience = expertise). In this editorial, I will point out some of the pitfalls I see in the inspection and reliability arenas and present some insight and solutions that will help "IJ" readers stay on track and emerge more successful as a result.

Data management is an important issue in today's world. We have data all over the place. Every manager is looking for ways to migrate data from platform to platform to save on the cost of re-gathering data and ways to share output from various platforms to better schedule and coordinate activities.
March/April 2004 Inspectioneering Journal
In the early days (circa 1988-1991) of introducing the petroleum refining and chemical industries in the US, to the idea that RBI implementation could be valuable many fell into the trap of focusing on how much money could be saved, to the exclusion of risk mitigation. This led to some unfortunate misconceptions that led to misapplication that led to dead ends in how to evergreen or maintain effective RBI programs. It is important to "get back to basics", with an improved perspective, based on experience, of where the evolution of the RBI process is leading us.
July/August 2003 Inspectioneering Journal
"Low Hanging Fruit" and "Step Change" are analogies that have been bantered around in our industries for some time. Picking the low hanging fruit is just the beginning and something that most passersby can glean. Also, real change that affects an entire organization, change that lasts, does not happen overnight and usually involves a combination of education, mentoring and recognition, appreciation and understanding of the limitations, resources, potential and culture of/at the various levels of the organization. Low hanging fruit is the easiest to see and pick, but what about the vast amount of fruit that resides amongst the leaves and branches? That is now the challenge of our industries. This is where the greatest harvest lays. Why have change and greater rewards been so difficult to realize? I believe there are many reasons, such as a lack of mentoring, a lack of appreciation and understanding of the limitations, resources, potential and culture of the various levels of the organization.

The large LNG facility is located on DAS Island, offshore of Abu Dhabi, in the Persian Gulf and experiences extremely high humidity year round. These conditions are known to produce a high potential for external corrosion and under insulation corrosion of carbon steel and mild steel alloys. If chlorides are present, which can drift from seawater, and are sometimes present in insulation, there may be a potential for Chloride Stress Corrosion Cracking (Cl SCC) of austenitic stainless steels (SS).

John has primary responsibility for NDE consulting and troubleshooting for BP around the world in the refining, chemical and gas processing industries. We at the IJ thought it might be valuable to spend some time chatting about his background, challenges he has faced recently and what he feels are some of the biggest challenges ahead for the Inspectioneering community.
May/June 2002 Inspectioneering Journal
We have discussed various factors that can affect the reliability of NDE techniques (i.e., probability of detection - POD and sizing accuracy) in Part 1. In general, it is difficult to quantify these uncertainties. In fact, it is impossible to fully quantify the uncertainties in NDE results. However, one can achieve a higher level of reliability by reducing or minimizing the uncertainties. We will discuss some of the steps one can take to minimize the uncertainties in NDE results. By minimizing or reducing the uncertainties in NDE results, FFS assessments can be less conservative, and thus provide more margin to the serviceability of the equipment.
January/February 2002 Inspectioneering Journal
Safety, environmental and economic pressures are motivating process industry (e.g. refineries & petrochemical plants) operators to consistently improve equipment reliability performance, optimize expenses and more accurately target resources where they will provide the greatest benefit. These improvements yield improved return on net assets (e.g. pressure vessels, piping and tanks). Companies that can better assure that decisions about repairs or replacement of equipment are more accurately arrived at are heading in the right direction. In order to equip operators with tools for better decision making, the American Petroleum Institute, within the last few years, has introduced Recommended Practice (RP) 579 Fitness for Service (FFS), which had been in development for several preceding years. The latest versions of the widely used inspection codes; API 510 (pressure vessels), API 570 (piping) and API 653 (above ground storage tanks) now reference this RP as a tool for determining the fitness for service of these types of equipment when corrosion, cracking, or other forms of deterioration are found and in the case of re-rating equipment.
November/December 2001 Inspectioneering Journal
A typical risk based inspection (RBI) analysis should include past inspection results, tempered by confidence in those results. For example, API's (American Petroleum Institute) RBI methodology and software when calculating the likelihood of failure side of the risk equation asks for past inspection histories. This includes dates of past inspections for potential damage mechanisms, the effectiveness of those inspection techniques to find the anticipated damage and amounts of coverage. Via this logic, the program constructs a factor to represent the probable damage population scatter band and multiplies this times the entered corrosion rates, cracking susceptibilities or bulk damage rates.
September/October 2001 Inspectioneering Journal
In part 1 we covered: - Evolution of the emergence of advanced NDE - External and internal motivators to develop more effective inspection programs - Risk based approaches - Sources of industry reference materials - Setting the Course - Why Inspect - Metrics for inspection program progress - Role of Risk Based Inspection I will now cover some of the remaining key aspects in assuring healthy evolution of the equipment integrity process.

Inspectioneering caught up with Dave Wang at the American Petroleum Institute’s (API) Spring 2001 Refining meeting in Atlanta, Georgia. We spent some time, near the pool at a break between meetings, discussing Dave’s background, experiences and the future of NDE from his perspective.
July/August 2001 Inspectioneering Journal
We've come a long way since my introduction to plant inspection processes in 1975 and certainly since the industrial revolution in the late 1800's. As I recall from history class it was the intent of the wealthy industrialist to make money, plain and simple. Safety and environmental responsibility were not the primary concerns, in some cases not concerns at all! Hence, for safety's sake, terms like "sweatshops" were coined. This was to connote factories and textile mills where human beings, often times young children worked, in poor conditions.

Firstly, I want to thank the inspection/materials engineering/ corrosion department manager, Giovanni Graziani, for agreeing to my visit and for sharing experiences with the Inspectioneering Journal community. The hospitiality of Giovanni, two of his senior area inspectors, Alessandro Grassi and Sauro Benini and Edy Sgherri their IT forgotten, nor the excellent food and espresso in the cafeteria.
September/October 2000 Inspectioneering Journal
In part 1 of this series the importance of keeping the RBI process as simple as possible was stressed. Software, consequence and likelihood issues were covered. Consequences were handled directly while likelihood issues were covered in discussion on damage modules and qualitative versus quantitative sections.
July/August 2000 Inspectioneering Journal
Hundreds of risk based inspection analyses have been completed by contractors and owner users worldwide, by now. Much is being learned as the various approaches gain acceptance. This editorial is only one perspective built upon the experiences of many.
November/December 1999 Inspectioneering Journal
Here are some of my observations based on numerous discussions with owner users and involvement in over 30 projects. This learning is from plant operators who have taken the RBI "plunge", after they have had time to think about their decisions and direction, using various software products. Some owner user answers are included and will be identified as such. In addition to the questions in part 1, I included a listing of some generic families of RBI tools or approaches.
September/October 1999 Inspectioneering Journal
There are many analysis tools available in the market that lay hold of the "RBI" claim. I wanted to bring you, the reader, "up to speed" on some of the available technology based on my experience as an RBI project manager, client manager and member of the American Petroleum Institute committee and working group compiling the RBI Recommended Practice 580.
September/October 1998 Inspectioneering Journal
I have observed through literally hundreds of discussions and reading numerous articles on risk-based approaches that at least one potential business pitfall is appearing when owner-operators choose to begin with a "Level 1" (very qualitative) approach. They may not have the confidence to take advantage of re-allocating resources from the "low" risk equipment to the "higher" risk equipment.
September/October 1998 Inspectioneering Journal
Inspection to determine mechanical integrity is important to verify that equipment is suitable for intended use, i.e. to prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable, or explosive chemicals as required by OSHA 1910.119 - Process Safety Management of Highly Hazardous Chemicals (and other jurisdictional codes).
May/June 1998 Inspectioneering Journal
The Environmental Protection Agency (EPA) issued the report on this catastrophic failure that involved two storage tanks in a Pennsylvania refinery. The report issued March 20, 1998, stated that while both tanks had roof replacements since their initial construction, no further information was available about routine inspection or maintenance procedures.
January/February 1998 Inspectioneering Journal
There is a potential for misconceptions about terms used regarding risk by non-risk management professionals. Understand that some risk is unavoidable. We can attempt to minimize risk to any extent desired, but without an effective process that addresses all the parameters we consider important it is more likely our level of effectiveness will suffer. There is more to these considerations than the likelihood of failure, which most inspection, materials and corrosion specialists understand.
September/October 1997 Inspectioneering Journal
The amount of serious questions regarding the various technology options for implementing an effective RBI program is growing by leaps and bounds. I, for one, have seen many forms of what various organizations refer to as RBI. Remember that there are to the Risk equation, i.e. likelihood or probability of failure and consequence of failure. The effectiveness of the RBI tool is highly dependent upon algorithm design, especially parametric considerations and their relative effect on one another and your objectives.
