1. Although condition-based maintenance can be the proper maintenance strategy for certain types of assets and situations, it is not the best approach for all assets and situations. One of the challenges of understanding Condition Based Maintenance is that it sounds similar to both preventive and predictive maintenance. What it is and how it works. Determine baseline standards for CBM What metrics indicate that an asset needs maintenance? The cookie is used to store the user consent for the cookies in the category "Performance". For example, this could involve online diagnostics used in turbine generator thrust bearing wear monitoring. By lunch, theres a frog in your throat. Chat now with an eMaint sales representative to get your questions answered. It is much easier to predict failure and fix it before it occurs, which means CBM can help reduce unplanned downtime and labour hours while increasing throughput. Definitions Maintenance functions can be defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Although condition-based maintenance can be used on most assets, equipment must meet certain requirements for CBM to be used effectively. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Not only will the parts always be on-hand (eliminating downtime), but inventory prices can be cut. Both are forms of proactive maintenance in that they rely on data to determine whether or not upkeep is necessary and prevent unplanned downtime, but thats where the similarities end. Using Micromains mobile technician app, maintenance workers can view information about the work order and provide status updates while working onsite or remotely. Check out a awesome infographic that details the Rise of Real-Time Facilities! adapt to the changing demands of building health. operational efficiency, and run energy Assets with an unpredictable failure rate that require high-precision maintenance. Predictive maintenance - is data-driven and impacted by preset parameters. Equipment assessments can be quite labor-intensive and may lack precision. Let's start with the basics and build from there. A CMMS gives you insight into the following information: 1. Confirm that your preventive maintenance, P-F Curve, and reliability-centered maintenance fundamentals are solid. A proactive maintenance strategy where work is scheduled in the future based on historical data insights on equipment failure.

Monitoring pressure levels allows maintenance staff to identify when and where a leak is likely to occur before it happens, instead of at the point of failure. If the pressure drops in a piece of equipment, it could mean that theres an internal problem requiring maintenance. With all the challenges that come with implementing a condition-based maintenance program, you may be wondering if it's worth it. By carefully matching each asset with the right type of monitoring, you increase the amount of time between P, when the asset begins to move down the curve, and F, when it completely fails. Basically, it's the same as condition-based maintenance except that the data is analyzed to make accurate predictions about future failures. CBM helps prescribe the optimal amount of maintenance for an asset, decreasing the chances of collateral damage to its systems.

Preventive Maintenance But a good program also reduces the number of scheduled work orders because PMs are only ever triggered by current conditions. Condition-Based Maintenance (CBM) is a strategy that considers information about the equipment condition to recommend appropriate maintenance actions. While condition-based maintenance relies heavily on technology and automated systems, like sensors and software, there will always be a human element involved. First, you get up feeling a bit more tired than usual. Sensors are expensive, and it can cost a lot to retrofit them into older assets. Maintenance teams must be able to collect performance data and analyze it properly to make smart and timely decisions based on the results. False positives may lead to unnecessary maintenance activities, resulting in cost overruns. Condition-based maintenance creates a safer workplace by reducing the likelihood of equipment failure. Assets that need to be run continuously even during maintenance. With all your data stored in one place, you can effectively manage work orders, purchase orders, inventory, and maintenance records all of which are required for a successful preventive maintenance program. Common types include vibration, infrared, oil analysis, pressure, temperature, and flow. You'll get the best return on investment (ROI) using CBM on your most critical assets. You also have the option to opt-out of these cookies. Facility Management The advantage of the strategy is that, ideally, younever over maintain your assets. And, most importantly, what it can and can't deliver. Condition-based maintenance combines recommended guidelines with repair and performance data to determine what tasks need to be completed and how often. Weve provided some tips, tricks and tools so you can understand condition-based maintenance a little better, use the strategy more effectively, and make your maintenance operation run like a well-oiled machine. Aims of this concept analysis include, (a) develop an operational definition for the term condition-based maintenance and (b) discuss the applicability . Understanding the P-F curve and the P-F interval is key to building an efficient CBM strategy. CBM doesn't rely on a schedule-based maintenance, but on indicators that can determine if the asset is about to break down or has broken down. It also captures information on viscosity, acid levels, water content, and more to determine the effectiveness of the oil as a lubricant. Identify conditional data anomalies You must understand everything about how equipment functions so you can properly calibrate sensors, spot problems as soon as possible, and prescribe the right cures. Condition-based maintenance, or CBM, is amaintenance strategyin which work is performed based on asset condition. As with any process change or new process implementation, condition-based maintenance comes with some challenges. Also, its harder to line up parts and people because you never know when youre going to need to assign the work.

Just like when you go to thedoctor,and they can X-ray you looking for problems instead of having to get you up on the operating room table. Why are they doing it? It's established by DoD Instruction 4151.22 "CBM+ for Materiel Maintenance". Build your insight and understanding of the future of It helps understand the PF curve (by predicting the time between fault and failure) for each asset and helps maintenance teams tend to them in time. Condition-based maintenance should make the early symptoms easier to detect, giving you more time to plan and organize a maintenance plan. Technicians use portable equipment for periodic tests or install sensors for continuous monitoring. The IAEA's condition-based maintenance strategy consists of a combination of visual inspection and continuous monitoring techniques on things like pressure boundary components, containment structures, main turbine generators and reactor coolant pumps. If a large piece of equipment needs to be monitored 24/7, predictive maintenance could be a better option than CBM. You don't have to worry about setting up your equipment for regular checkups because everything is monitored in real-time. One example of condition-based maintenance is monitoring pressure readings on equipment with water systems. This cookie is set by GDPR Cookie Consent plugin.

Put simply, it's about fixing things before they break. Understand the business impact of Fiix's maintenance software. Sensors are expensive, and it can cost a lot to retrofit them into older assets. If you are unable to implement a given . Work is performed at just the right time to prevent failures without introducing the risks, costs, and labor of over-maintenance. With other techniques, though, you usehighly sensitivesensors, soyouresuddenly Superman with X-ray vision and super hearing. Sometimes organizations adopt condition-based maintenance technology without adapting their people or reviewing processes. Condition-based maintenance (CBM) is a maintenance strategy that monitors the real-time condition of an asset to determine what maintenance needs to be performed. Air surveys use ultrasonics to detect leaks in compressed gas systems. With something like preventive maintenance, you know exactly when youve scheduled work and who youve assigned to complete it. Condition-based maintenance (CBM)is aproactive maintenance strategy that involves monitoring the actual condition of an asset to determine when maintenance is needed. 5. The machine progresses from top working condition to point of failure, and then down from there until actual failure. 3. One of the pieces of information that can be obtained from the condition-based maintenance model is the estimated service life of the building components, which allows analysing the impact of different maintenance strategies on the components' durability. By inviting their input, they become active participants. This article is a complete guide for optimizing condition-based maintenance (CBM), including what CBM is, the different types, how its used and how to use it for maximum return. Hippo provides a comprehensive and easy yo use CMMS for streamlining your asset management. It can also help you identify trends in failure rates, which can indicate when a piece of equipment is due for replacement or repair. Eventually, patterns will emerge from the data and show when a machine may be starting to fail. potential in portfolio O&M, increase efficiencies, and Which technicians are assigned to cover which tasks Enhance the in-store customer experience, Integrating sensor data with maintenance software, such as a CMMS, can help reliability engineers, maintenance managers and technicians capture, organize and analyze information much easier, quicker and more accurate. Once the connection is established and the data is flowing, the manager sets up automatedcondition-based work ordersto trigger when the motors temperature moves out of its normal range of 0 and 100 F. The goal of CBM are the same as any other maintenance management system: The key differences between predictive and condition-based maintenance come down to the following: It depends on what makes sense for your business. If only youd had some chicken soup early on, you could have saved yourself the misery. The use of condition-based monitoring tools like sensor equipment helps automate part of the process. Another benefit of condition-based maintenance is how far it puts you ahead of the P-F curve, which is the curve your asset follows as it moves toward failure. While a CBM program isn't cheap initially and can take some time to get up and running, you eventually can receive a lot of value from it. Install sensors and other condition-based monitoring tools to track asset health But sometimes, the rush to adopt and implement causes facilities to disregard critical steps, like ensuring your maintenance program has mastered the fundamentals ofreliability-centered maintenance. An extreme example would be trying to use vibration sensors onthe engineof a large ship. Infrared cameras and thermal sensors are used to determine when a piece of equipment has become too hot and alerts the maintenance team so they can take the necessary steps to fix it. Fiix by Rockwell Automation Inc. All rights reserved. Part of the JDM Technology Group. Not in the sense that its new or currently in fashion. The condition of the asset is checked through: visual inspections various NDT tests performance data (often gathered by different sensors/tools) Setting up and running a condition-based maintenance program takes expensive expertise and equipment. Condition-based maintenance (CbM) refers to a collection of activities, inspections, tests and procedures that are performed in response to the failure or destabilization of equipment, a machine or a material. Remember that condition-based maintenance doesnt only concern the maintenance team. At this point, select a maintenance strategy for each critical failure mode. Condition based maintenance (also known as CBM) is when maintenance operations are performed depending on the current condition of your assets. Less expensive and time-consuming than preventive maintenance. But it can get a bit more complicated when you move away from looking for leaks and touching pipes feeling for excess heat.

How to measure asset reliability with a bathtub curve? How critical are potential failures? The AF definition is: Definition: Condition-Based Maintenance (CBM) can be defined as a set of maintenance processes and capabilities derived from real-time assessment of weapon system condition obtained from embedded sensors and/or external test and measurements using portable equipment. We're constantly working to improve your Facilio Even if these assets arent currently under a preventive maintenance plan, you can still minimize downtime and maintenance costs by preparing for the assets eventual degradation. Lets start with the basics and build from there. Baselines can be established in many ways, from manufacturer recommendations to historical trends. Your maintenance and reliability teams should ask themselves some fundamental questions. Get all How are they getting it done? Another important consideration is the type of equipment in question. In many industries, production relies on maintaining the right pressure within equipment so fluid, gas, or air can move through a pipeline or hydraulic hose properly. The most common methods include the following: In addition to these physical inspection methods, there are several other ways that you can monitor equipment for signs of wear and damage. The better the match, the more time you have to react. Save hours on admin work with these templates. Condition-based maintenance and predictive maintenance are both forms of proactive maintenance that occur before equipment breaks down. Prior to that, he wrote for textbooks and video games. Noteworthy articles on all things building ops. The idea is that this real-time monitoring will give maintenance teams enough lead time before a failure occurs or performance drops below an optimal level. Basically, its a bit harder to schedule your resources because you dont know when PMs are going to pop up. Unlike calendar or meter-based maintenance, which occurs on a fixed schedule, CBM is only performed when certain indicators show signs of decreasing performance. Thus, it is regarded as condition-based maintenance carried out as suggested by estimations of the degradation state of an item. Condition-based maintenance. Create a set of standard maintenance procedures technicians can follow when dealing with complex assets. When they degrade or fall out of alignment, the intensity of the vibration increases. [4] Over time, the terminology of maintenance and MRO has begun to become standardized. To achieve condition-based maintenance, the manager needs access to gather temperature data from the motor regularly so that when it overheats, they know.

Oil analysis helps diagnose the internal conditions of oil-wetted components and their lubricants. For an extreme example, first your asset gets hot. Condition monitoring systems do not provide information on how long an asset will last before failure occurs, unlike predictive maintenance systems (PdM), which monitor performance over time and define failure modes and exact times of future losses. How to perform Facilities Condition Assessment? However, for less valuable assets, CBM can decrease maintenance cost. Condition-based monitoring (CBM) is most beneficial to critical assets that significantly impact production or operations. This involves keeping tabs on the state of an asset using certain performance indicators. The cookies is used to store the user consent for the cookies in the category "Necessary". The use of sensor equipment and other condition monitoring tools reduces labor. Get 20+ frameworks and checklists for everything from building budgets to doing FMEAs. However, most of them are challenges that a CMMS or enterprise asset management (EAM) software mitigates. stores across your portfolio. A mobile CMMS comes with a built-in chat function that makes it easy for managers to communicate with each other onsite, as well as push notifications that notify managers of important changes. 3. dimenson of your enterprise, Empower workforce, make data-backed decisions, and A PM is triggered only when the current number lands outside the predetermined comfort zone. Good sensors should be able to survive the extremes of a manufacturing setting, so you wont have to replace them often, but there are ongoing costs for periodic re-calibration. The goal of condition-based maintenance is to continuously monitor assets to spot impending bearing failure, so maintenance can be proactively scheduled before the failure occurs. For successful CBM, you must ensure your inspection intervals are smaller than the P-F interval so you can catch a failure after its detectable, but before it actually occurs. Asset criticality is another criterion you should consider before utilizing condition-based maintenance. .Condition-based maintenance can act as a guide on the road to failure and back. Using sensors and spot readings are the most common ways real-time data is collected for analysis. The main purpose of CBM is to prevent . Perform condition-based maintenance. For example, installing accelerometers on machines that vibrate a lot is common. The time between maintenance increases because repairs are only done on an as-needed basis. 2 Several aspects on condition based maintenance approach 2.1 Definition. But there are important differences between the strategies. Maybe you notice a slight headache. You can choose to collect data at certain intervals or continuously through things like sensors, visual inspection or scheduled tests.

Condition-based monitoring, condition monitoring, and production monitoring are terms often used in the same context. However, they differ in that CBM refers specifically to using insights from condition data, whereas predictive maintenance may imply some level of predicting faults or failures with more advanced analysis. Highly critical production assets with high repair and replacement costs. insights on contracted services, Visualise assets, track performance, and A proactive maintenance strategy where assets are maintained on an as-needed basis (based on signs of impending equipment failure). Condition-based maintenance software provides a fast and easy way to aggregate condition monitoring data so you can create work orders and track the success of your CBM strategy. As more and more equipment is equipped with IoT capabilities, devices are more likely to feature sensors that collect performance data. These methods can include low-tech approaches, such as observation by a technician, or more technologically advanced processes, like gathering data through sensors. The math is so complex its easier to just think of the algorithm as a crystal ball that actually works. The biggest blockers to adopting of CBM technology are cost of large scale implementations and their perceived complexity. For example, if you have an older piece of machinery or equipment that has had problems, then predictive could be a good option for maintaining its health without having to shut down production every month or two because something didn't work right. What it is and how it works. Generally, anasset is far down the P-F curve before you can see the symptoms unaided. A condition-based maintenance strategy is implemented to save time, reduce maintenance costs, and optimize maintenance schedules so failures are prevented and uptime is maximized. This imbalanced force will happen one time per revolution of the fan, producing increased vibration signals. insight-led operations across buildings and Condition Based Maintenance Plus (CBM+) is the application and integration of appropriate processes, technologies, and knowledge-based capabilities to improve the reliability and maintenance effectiveness of Department of Defense (DoD) systems and components. These devices measure the frequency and amplitude of vibration, which can indicate problems with bearings or other moving parts. As you move through time, there are also instances when faults can be detected before total failure. The likelihood of disrupting production is reduced as CBM is usually performed while assets are working and doesnt normally require equipment to shut down for inspection. For example, rotating equipment, such as compressors and motors, exhibit a certain degree of vibration. Data is collected either at certain intervals or continuously through sensors, visual inspection, performance data, and/or scheduled tests. This can signal to a technician that the bearing is on its way to failure. In this article, we discuss the difference between the two and how you can use condition-based maintenance effectively at your facility. It should be both economically and technically feasible. Are those failures likely to recur? One of the biggest advantages of condition-based maintenance is that it is non-invasive, meaning real-time data is being collected while the machine is still running without adjusting the way it operates. Even companies with established condition-based maintenance (CBM) routines do not use them for every single one of their assets. Because CBM provides an early warning system for equipment failure, you can control inventory much more effectively and wont need as many emergency spare parts. A couple more examples should make it easier to see the differences between condition-based maintenance and other maintenance strategies. For example: with condition-based, you have an engine that usually runs at temperature X. That means condition-based maintenance solves the problem of over-maintenance, where youre using time, energy, parts and materials when you dont need to be. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The more high-tech examples are also the more recent ones. Maintenance software also gives you the ability to automatically trigger a work order when certain measurements fall outside the established baseline. Consider factors like operating conditions, as sensors built to withstand harsh operating environments generally cost more. Heres a quick guide to everything you need to know about condition-based maintenance. Also, choosing the proper sensor is critical. It is also crucial to be able to observe these changes in performance far enough in advance of failure so maintenance can be completed before the asset fails or deterioration affects production. Baselines are the established thresholds that indicate a healthy and fully functional system. [1] Strange clunking sounds. Initial and operational costs are often higher due to the need for additional sensors and equipment. Upon recognizing this need, the agency developed and standardized how to implement a CBM program in a publication entitled, Implementation Strategies for Condition-based Maintenance at Nuclear Power Plants.

Using this tool, its easy for maintenance teams to gauge when a machine is receiving an abnormal amount of electricity. It costs money to train technicians to work with new equipment, and the equipment itself is pricey and finicky. Many of these forms of condition monitoring can be used together to gauge the health of an asset. Steam where there shouldnt be any. Training also involves getting everyone on board with the change and effectively managing the change. If the machine is supposed to produce five tin cans a minute but youre only getting four, something is the matter. Here theres more overlap, so its even harder to see the differences. Another important consideration is the criticality of your assets. Unify building operations data and uncover portfolio intelligence in real-time, Activate connected buildings at scale to unlock O&M efficiencies From here, you can escalate your condition-based maintenance strategy into a predictive or preventive maintenance strategy. This means less downtime, reduced backlog, and fewer costs. Condition-based maintenance is a predictive maintenance strategy where various elements of an operating asset are observed and measured over time to identify and prevent deterioration and possible failure at the earliest possible moment.
