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.

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.

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.

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.

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.
