It has contracted SKF to develop the complete engineering strategy for its new Indonesian gas extraction and processing plants. A preventive scheduled maintenance works by taking the assets offline and inspected at designated intervals, and repaired if necessary. âThere is a âworstâ strategy and thatâs reactive maintenance, but the best strategy is the one that helps equipment function at its best, safely, and without too many costs.â. Michael Guy Deighton, in Facility Integrity Management, 2016. This chart is all about how each strategy allows you to plan and identify risks early so you can reduce the likelihood of accidents or increase compliance on a group of assets. There are a host of other maintenance types that work well for all kinds of organizations, from small shops drowning in paper work orders to data-driven enterprise operations for whom predictive maintenance is a reality. The most expensive type of maintenance is Emergency Maintenance because this is the type of maintenance that is so urgent that you drop everything to run off and fix the problem. For failure modes where the P-F interval shows a large variability, condition monitoring is not an effective strategy. Maintenance strategies are complicated. A common rule of thumb is that the interval between CBM tasks should be one-half or one-third of the P-F interval. This requires an efficient and effective process for data gathering, data analysis, decision making and finally intervention. 5.3 Preventive Maintenance . Most failure modes are not age related. The basic application of each strategy is shown in Figure 1. Optimised Maintenance provides Maintenance Specialist consultants with applied industry based trades and engineering experience.

Failure Finding Maintenance is conducted at fixed time intervals typically derived from legislation or risk based approaches. So although a run-to-failure strategy can be a good option, make sure you decide wisely. Preventive maintenance (PM) is maintenance regularly performed on a piece of equipment in working condition to reduce the risk of it failing. Predictive maintenance (PdM) aims to predict failures before they happen so maintenance can occur at just the right time. So when a corrective maintenance work request is raised it is essential that you prioritise it properly to make sure that where possible you defer the work request and give your team the time to properly plan and schedule the work. Time-based preventive maintenance is when tasks are scheduled on an asset at a certain time interval, such as the first of every month or every seven days. Predictive Maintenance Strategy Training. Maintenance is the procedure of finding the faults in any equipment/Machine and also removal of fault. GLOMACS training courses in Maintenance Engineering support you to take your Asset and Maintenance management processes to a higher level. 10. Predictive Maintenance really is a type of Preventive Maintenance as they both see you conducting maintenance before the failure has occurred. Whatâs the biggest maintenance cost for each asset? A good example would be something like general area lighting in an industrial plant where you will simply wait till you have a number of lights that have ailed and then you replace them. A good dose of prescriptive or predictive maintenance is often enough to cure unnecessary downtime. The issue is though that most people think of the traditional Time-Based Maintenance when they talk about Preventive Maintenance. All Preventive Maintenance should be Planned Maintenance as it has been identified upfront and there is no reason why it would not go through the normal maintenance planning & scheduling process. Preventive maintenance can be defined as "an equipment maintenance strategy based on replacing, or restoring, an asset at a fixed interval regardless of its condition. This asset specific solution enables the maximum value to be extracted. However, older technology devices and newer high-tech devices cannot be efficiently managed using the same strategies because of their different characteristics. This is when technicians get bogged down by unnecessary tasks and cost the organization time and money. 2.New operating components with insufficient maintenance history to support the use of alternate maintenance strategies. More insight into causes of breakdowns, Investigation of failure modes to determine best maintenance strategy, If executed properly, provides the most efficient maintenance schedule, Requires time, skill and financial resources to be effective, Ideal for low-priority or inexpensive equipment, Can cause excessive downtime that impacts production, High costs associated with parts and supplies, When used with a CMMS, asset knowledge and work history is recorded centrally, PM creep can occur, leading to a strain on resources, Post-maintenance breakdowns can occur when tasks are not completed properly, Uptime is optimized as maintenance only occurs when necessary, Decision making is completely data-driven and condition-based, There can be high costs associated with implementing, It’s an advanced approach that requires analysis and specific skill sets, Reliability is maximized as each piece of equipment gets its own maintenance plan, Maintenance is proiritized according to equipment ciriticality, which reduces risk, Requires large investments in time and money, Many teams do not have the resources to adopt this approach. The above table of types of maintenance does not include Autonomous Maintenance or Autonomous Care (also referred to as Front Line Maintenance in other organisations). It uses condition monitoring and machine learning tools to predict when to do maintenance, but it also lays out exactly what kind of maintenance to do to help that piece of equipment perform better for longer.
