Implementing RCM increases equipment availability, and reduces maintenance and resource costs. RCM does not readily consider the total cost of owning and maintaining an asset. Additional costs of ownership, like those considered in evidence-based maintenance, are not taken into account, and are therefore not factored into the maintenance considerations.
There are several different methods for implementing reliability centred maintenance that are recommended, summarized in the following 7 steps. The first step is to select the piece of equipment for reliability centred maintenance analysis. The equipment selected should be critical in terms of its effect on operations, its previous costs of repair, and previous costs of preventive maintenance.
Find the best equipment for RCM with this criticality analysis template. The equipment belongs to a system that performs a crucial function. The system can be large or small, but the function of the system, and its inputs and outputs, should be known. For example, the function of a conveyor belt system is to transport goods. Its inputs are the goods and mechanical energy powering the belt, while its outputs are the goods at the other end.
In this case, the electric motor supplying the mechanical energy would be considered as part of a different system. In step 3 the objective is to list all of the ways that the function of the system can fail. For example, the conveyor belt may fail by being unable to transport the goods from one end to the other, or perhaps it does not transport the goods quickly enough. With the help of operators, experienced technicians, RCM experts and equipment experts, the root causes of each of the failure modes can be identified.
Root causes for failure of the conveyor could include a lack of lubrication on the rollers, a failure of a bearing, or a loosened belt. Use this template and stop spending hours doing a root cause analysis. In this step, the effects of each failure mode are considered. Equipment failures may affect safety, operations, and other equipment. Schedule repeatable tasks for your assets with ease. Keep things running smoothly and receive work requests.
Manage safety, regulatory compliance, and standard operating procedures on the go. Track usage by work order and asset. Create low quantity alerts. Assign, comment, and track the status in real-time. Global Procedure Library. High-level organizations often practice preventive maintenance PM within a reliability-centered maintenance RCM framework to increase equipment lifespans, enhance reliability, and optimize savings.
Though both terms include scheduling work orders in advance—based on usage, time, or performance triggers—they are not the same. Preventive maintenance is a general type of proactive maintenance , while RCM is a maintenance strategy that combines various types of maintenance intending to optimize efficiency.
Preventive maintenance refers to scheduled maintenance activities completed to keep assets in optimal condition, prevent unplanned downtimes, and maintain safety. Common PM tasks include inspecting, cleaning, lubricating, adjusting, replacing, and repairing equipment parts. These tasks are always performed before asset failure may occur. What events cause each failure? What happens if and when the failure occurs? How much impact does that failure have, and how does it matter?
How can the failure be prevented or the risk of this failure be reduced? Written by Larry Johnson. Subscribe to Email Updates.
A failure mode and effects analysis FMEA is one example of a tool that can be used to define several failure modes that can then be mitigated. When reviewing these points of failure it is also helpful to define operating ranges for important parameters. An operating range will give you a tangible measurement that defines a potential failure when values move outside of that range.
Since an RCM approach will prioritize the failure modes for each equipment system, it can also be used to select appropriate maintenance solutions. In some cases, an in-line monitor could be used as a conditions-based solution, or a preventive maintenance schedule may be followed to replace common consumables and keep up with routine maintenance tasks to keep equipment in optimal working condition. Coupled with facilities management asset tags to streamline documentation and monitor equipment usage and conditions, these tools support an effective RCM program.
Any maintenance program will benefit from better organization. Given the complexity of many facility systems, using a CMMS combined with a proven framework can help overcome several common issues.
An RMC project framework can be described in 4 common steps. This process is best understood as a loop that can be repeated regularly to improve maintenance decisions based upon the latest available data.
