Overview of Management of Change (MOC)
Management of Change (MOC) is a best practice used to ensure that safety, health, and environmental risks and hazards are properly controlled when an organization makes changes to their facilities, operations, or personnel. Having a properly implemented MOC policy in place when implementing changes can help ensure that new hazards aren’t introduced and the risk levels of existing hazards aren't being increased. Inadequate MOC on the other hand has the potential to increase risks to the health and safety of employees and the environment.
Effective MOC involves review of all significant changes to ensure that an acceptable level of safety will be maintained after the change has been implemented. From this evaluation, the proposed change can either be set for implementation, amended to make it more safe, or rejected entirely. Should the change be implemented, personnel should be informed about the change and how to maintain a safe workspace in this new environment.
Under the Occupational Safety and Health Administration’s (OSHA's) Process Safety Management (PSM) standard, performing MOC is required when making changes that could affect the safety of a facility. This can include changes in process chemicals, technology, equipment, procedures, and the number of employees involved in a process.
While MOC is generally used to examine the effects of a proposed permanent change to a facility, temporary changes should not be overlooked. A number of catastrophic events have occurred over the years due to temporary changes in operating conditions, staffing, etc. For this reason, an effective MOC program should address all changes that could affect the safety of a facility or personnel, regardless of whether or not it is permanent.

Integrity Operating Windows (IOWs) have a subset of operating variables that are important for degradation monitoring, but may not have direct operational controls. Per API RP 584 Integrity Operating Windows, these are known as IOW Informational Limits, which are often neglected or misunderstood by operations or technical personnel within a plant.

Evaluating remaining wall thickness of an asset is not enough to ensure its continued safe operation. Proactive strategies should be implemented to assess the entire environment affecting an asset’s condition, including the development of more effective inspection plans.

May/June 2016 Inspectioneering JournalBy Jeffrey Foushee at Pinnacle Advanced Reliability Technologies, and Ryan Myers at PinnacleART
Data, in pure form, consists of raw, unorganized facts that need to be processed. Data can be found in databases, documents, drawings, reports, spreadsheets, and numerous other sources. Having data on hand is useful, however, it’s often inefficient and counterproductive to make decisions based on data in its raw form.

If we could measure, understand, mitigate, and most importantly, control corrosion, we can do a better job of keeping the product in the pipes. To accomplish this task, we needed to know what is causing the corrosion and how to control it.

One of the major challenges inspectors and plant operators face after each turnaround is to ensure that all repair and scope work is and was completed in accordance with the client’s requirements. Sometimes that verification will be to ensure work was completed in conjunction with the applicable codes, and sometimes that it was completed in conjunction with the client’s own in-house specifications.

Based on my 45+ years of experience working with fixed equipment mechanical integrity (FEMI) issues in the refining and petrochemical processing industry, this article summarizes what I believe are the top 10 reasons why pressure vessels and piping systems continue to fail, thus causing significant process safety events (e.g. explosions, fires, toxic releases, environmental damage, etc.).

Fixed equipment mechanical integrity (FEMI) failures are not caused by damage mechanisms; rather, they're caused due to failure to create, implement, and maintain adequate management systems to avoid failures. Nearly all failures that have occurred in our industry could have been avoided if these human systems were more robust and sustainable in providing the primary layers of protection for FEMI.

These posts came about because, from time to time, I’m asked why some operating sites don’t seem to pay adequate attention to the need to protect and preserve pressure equipment integrity (PEI). Too often a few sites don’t seem to “get it” until they have a major process safety event associated with a failure of pressure equipment. When that happens, they are suddenly on...

Without doubt management needs to ensure that the appropriate resources (human and budgetary) need to be provided for corrosion control and prevention. The C/M engineer/specialist or other responsible party needs to assure that management is advised annually at the appropriate time what resources will be needed for the next budget cycle.

High Temperature Hydrogen Attack (HTHA) is a long known and still occurring degradation issue for fixed equipment construction materials in the hydrocarbon process industry where hydroprocess plants (hydrogen plus hydrocarbons) are in service. Though HTHA failures in these units are the focus of this article, it is important to recognize that HTHA damage can also occur in high pressure boiler tubes, hydrogen producing units, synthetic gas units, ammonia plants and other equipment where hydrocarbons may not be involved but high temperatures are involved.

High temperature oxidation is not a real common type of failure in our industry, but it can and does happen when temperatures exceed design maximums. All metals oxidize, even at room temperature, and in many cases that slow oxidation process actually protects the metal from rapid oxidation.

High temperature sulfidation is probably the most common high temperature corrosion nemesis in the refining industry, since there are very few “sweet” refineries still in operation. Sulfidation corrosion typically is of concern in sour oil services starting at temperatures in the 500F (260C) range.

It's probably more important to those of us who don't have a brain tumor. Unfortunately, it's precisely because piping inspection is not neurosurgery that it's often done poorly, which can lead to significant impacts on process unit reliability, or worse, a catastrophic event, where people can get hurt.
