Hello everyone, I'm wondering if there are any established standards available for assessing the criticality rating and index of rotary equipment. I am aware of one standard, NORSOK 008, but I am curious if there are any other published guidelines or standards on this topic. Thank you in advance for your assistance.
I am not familiar with a specific method for calculating criticality. Is there a way to determine the severity of potential Health, Safety, and Environmental (HSE) consequences on production and economic aspects? Can I access your Norsok 008 guidelines to understand the process better? Do these guidelines provide a framework for calculating criticality, or do organizations need to develop their own risk assessment matrix?
Ali, I'm not aware of any specific standard that definitively determines the criticality of equipment. The reason for this is that the criticality of equipment is highly dependent on its function and the service it provides within a given system. As a result, it cannot be universally calculated as a standard measure, as it varies based on company policies, functions, and services. However, there are several standards available to assist in calculating the criticality of equipment, based on three main factors: economic criticality (including loss of profit opportunities, maintenance costs, and operating costs), safety criticality, and environmental criticality. These factors are all interconnected and can be assessed through a matrix relationship to determine the likelihood of failure. It is important to note that these factors are influenced by a multitude of variables. I hope this information has been helpful to you.
Originally shared by Luca, there are various standards available to help calculate the criticality of a situation. These standards are primarily centered around three key factors: economic criticality, safety criticality, and environmental criticality. Economic criticality considers factors such as potential loss of profit opportunities, maintenance costs, and operating costs. Safety and environmental criticality are also important considerations. Luca is seeking information on internationally recognized standards related to economic factors. Thank you.
When researching this issue, I initially consulted the American standards MIL-STD-882D – Appendix A and later MIL-STD-1629. Quality America Inc. offers valuable insights on the subject. This article on criticality analysis can be found on their website [INSERT LINK]. I define "criticality" as the product of "probability," "severity," and "detectability," which is crucial for determining equipment classification. It is important to consider the specific functions of the equipment and the potential consequences of failure to the organization. While norms are helpful, it is also essential to use common sense and not be overly restricted by them. In my experience, criticality assessments have involved lengthy discussions to establish classification criteria. This collaborative approach ensures that all parties involved are aligned. Regards, Rui.
If you're looking for a valuable resource, consider downloading the MIL-STD-1629A standard from popular search engines. While it may be slightly outdated, the core concepts remain relevant and unchanged.
Absolutely, you're on the right track with NORSOK 008. You may also want to explore ISO 14224, which is applicable to fixed equipment but its concepts can be broadened to rotary equipment. Its sections on collection and analysis of reliability and maintenance data could be really useful. Additionally, API RP 581 is used to determine risk-based inspection methodologies, and while primarily about fixed equipment, it can offer some insights into the criticality assessment. Remember, many of these standards can and should be adapted to fit the specific nature of your operations.
Hi, that's a great question! In addition to the NORSOK Z-008 standard you mentioned, you might also want to explore the ISO 14224:2016 standard. It provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries and could be a valuable resource as it also covers rotary equipment. It's worth noting that different industries might have their own specific standards, so you may want to check standards applicable to your specific field.
Absolutely, aside from NORSOK 008, there are various other standards used in assessing the criticality of rotary equipment. Consider looking into the ISO 14224 standard, an International Standard that provides a comprehensive basis for the collection of reliability and maintenance data, which could be utilized for criticality assessment. API 686 could also be beneficial. It's the de facto standard for machinery installation and could provide some insights on assessing criticality of rotary equipment. Remember, the choice of standard often depends on your specific application and industry sector.
Hello, I do believe API (American Petroleum Institute) has a couple of guidelines you might find helpful, specifically API RP 580 and API RP 581. These revolve around Risk-Based Inspection (RBI) and may provide some useful insights into assessing the criticality of your rotary equipment. Another organization to check would be ISO (International Organization for Standardization). They have a broad range of standards that often touch on these topics. Hope this helps!
