Viewpoint: Interoperability & The Future Of Engineering Productivity


Gerhard Sallinger, President, Intergraph Process, Power & Marine

Skyrocketing energy demands… The rising need for raw materials to produce more consumer goods… An ever-expanding global economy connecting the continents… These macroeconomic forces are spurring further productivity investment by owner operators (O/Os), as well as engineering, procurement and construction (EPC) companies. These entities need every possible advantage to differentiate themselves from their competitors.

One of the trends spurring this productivity revolution can be summarized as interdiscipline integration—or interoperability. Interoperability is managing, accessing and sharing information seamlessly between the engineering design basis, reliability, maintenance, content management and other systems. It should be a core value and will result in productivity gains both between disciplines within the O/O organization and across the entire plant value chain. Interoperability enables teamwork, and is critical for plant asset management. While the solution to poor asset performance is conceptually clear, few companies currently have a plant asset information management strategy in place that is adequate to support the required interoperability initiatives.

By automating the processes that currently exist between the project phase and the operations and maintenance phase of a plant, interoperability can improve the handover process between EPCs and O/Os. Handover carries a connotation of being a very manual process, but the opportunity exists for people to automate this process dramatically, typically saving $10-15 million and up to a year of effort after the completion of a CAPEX (capital expenditure) project. One of the root causes of owner/ operator interoperability problems is a degradation of engineering design basis information. Utilizing an automated, effective and complete handover process will effectively make the manual handover process disappear, allowing the engineering design basis to be used for the life of the plant by non-engineers.

Significantly, O/Os have the most to gain from improved interoperability, because research has shown that they bear the largest share of costs resulting from efficiency losses attributable to inadequate handover. However, interoperability opportunities are not isolated to handover and exist throughout the plant life-cycle. Poor management of plant asset information has an impact on the O/O’s financial performance. Research studies estimated the cost of poor interoperability across the complete design, build and operate supply chain to be $15.8 billion per year in increased CAPEX and OPEX (operational expense). Of these costs, two-thirds are borne by O/Os—which incur most of these costs during ongoing facility operation and maintenance (O&M).

Participants in one survey felt that poor interoperability between groups representing the design/build and operate/maintain stages averaged 3% of plant revenues. And opinions in the survey were relatively consistent among O/Os and EPCs. While no analysis was done as to the source of these losses (CAPEX or OPEX), the potential savings are obviously large and compelling.

The day is coming when O/Os will be ready to demand interoperability—and EPCs will say they can make it happen. Vendors should support openness standards such as ISO 15926 to provide the necessary tools to ensure project information is reflected accurately in operations and maintenance systems. We simply need to prepare for this day, and make sure we do our part to make it a reality. MT

More Efficient & Cost-Effective Turbine Maintenance

In the past, power plants would have to shut down to perform maintenance procedures on their collector rings and brush holders, resulting in costly downtime. Worse, if a ring or brush holder failed, so could the generator. According to Dave Cutsforth, founder of Cutsforth Products and a pioneer in on-line truing, the brush holder is the root cause of most collector ring failures. As a machine rotates, poor contact between carbon brushes and the ring surface causes electrical wear. Poor holder design, foreign materials and improper maintenance are all contributors to this problem. Brushes are designed to be replaced. The ring, with proper maintenance, should last for years. Cutsforth’s Easychange Brush Holder System allows for the maintenance of turbines while they are online, totally eliminating the need for a shutdown. Plus, because the actual repair can be done at operating speeds, it has proven to be more accurate and longer lasting than performing a similar process off-line.

Solution Spotlight: Thumbs Up For Better Recip Reliability


An active reliability program for reciprocating machinery, based on proven dynamic monitoring and analysis techniques, enables meaningful asset protection, mechanical condition monitoring and economic performance assessment. According to Windrock, Inc., end users of the large reciprocating compressors and engines used in natural gas gathering and storage, gas transmission, oil refi ning and petrochemical manufacturing can achieve signifi cant cost advantages by adopting an appropriate reciprocating machinery reliability program that will reduce downtime, eliminate unnecessary maintenance and maximize unit operating effi ciencies and production capacity.

As corporate management mandates of plant and fi eld capacity increase, the criticality of individual reciprocating compressors and engines is increased. A comprehensive reliability program for these machines is essential to meet these increased production demands. Monitoring of static operating data alone is no longer suffi cient. Dynamic measurement and analysis of the compression and combustion processes in engines and compressors is necessary to provide information to properly monitor and diagnose reciprocating machine problems and assess machine mechanical condition and performance.

Windrock manufactures portable and online monitoring systems for reciprocating compressors and engines utilizing patented technology to turn dynamic data into easily interpreted information. On compressor and engine cylinders, dynamic pressure measurements—referenced to each degree of crankshaft rotation—are converted into pressure measurements referenced to the precise displacement of a reciprocating machine’s piston throughout its entire stroke. In doing so, the cylinder’s Pressure-Volume curve can be automatically analyzed. Moreover, the Windrock systems can provide alarms and automated diagnosis of compressor problems such as leaking valves, leaking rings, leaking packing, overloading of piston rods and the dangerous lack of piston rod load reversal. Other dynamic measurements include crosshead and cylinder vibration, piston rod drop and runout.

On engines, dynamic pressure measurement allows statistical comparison of power cylinder peak fi ring pressures to detect early, late or incomplete combustion, including the detection of extremely harmful pre-ignition and detonation conditions and also the ability to measure and adjust power cylinder peak pressure balance. Other dynamic measurements include power cylinder vibration, plus primary and secondary ignition measurements.

Utilizing the data collected by portable or online systems, analysts and operators can effectively elect to perform or defer maintenance, depending upon the impact on production. Windrock’s comprehensive On-GuardTM online systems utilize combinations of modules such as Windrock’s patented C-Guard (compressor cylinder pressures, temperatures, vibration and rod drop), V-Guard (API-670 vibration) and E-Guard (Power cylinder pressures). Windrock’s 6310 portable systems are used for detailed and cost-effective analysis of multiple reciprocating compressors, engines and rotating machines.

Windrock systems can be an integral part of a comprehensive, active reliability program for any company that runs reciprocating machinery. The company notes that return on investment (ROI) studies indicate short payback cycles for the systems. MT

Uptime: Ten Key Questions


Bob Williamson, Contributing Editor

“Maintenance” alone cannot make equipment and processes reliable. Often, a maintenance department is reacting to problems caused by decisions and/or actions of other departments. Further, in high-reliability plants, the maintenance department is NOT a “supplier” of maintenance services to the operations group “customer,” but rather a “partner” WITH the operations group for improving equipment and process reliability. Given this perspective, I would ask my own 10 questions to answer the one asked at MARCON. (By the way, the “correct” answer for each of these is “yes.”)

  1. How close to 100% reliability are your critical, constrained, high-risk equipment and processes? Are they doing what they are supposed to do first time, every time? 100% is attainable, desirable and the right goal for truly critical assets. A racecar that completes a 500-mile race within the planned finishing position is “reliable.” But, don’t confuse “reliability” with “availability.” 100% reliability means that it does what it is supposed to do first time, when needed, with no unplanned downtime. Planned downtime for necessary preventive maintenance to improve or sustain the process reliability will reduce the calendar time availability.
  2. Is your reliability program driven by operations management versus maintenance department management? Reliable equipment as part of a process generates revenue and/or avoids penalizing costs in the cases of health, safety and environmental incidents. Unreliable equipment stalls a process, prevents revenue generation and reduces “return on capital assets.”
  3. Are equipment and process performance data routinely collected and analyzed, root causes determined and corrective actions implemented and verified versus tracking and trending OEE calculations and other metrics’ percentages? So often we become enamored with relative numbers (percentages) that are several levels removed from the actual results and the reasons or causes of good or bad performance. Numbers can look good but the actual results may not be so good. For example, the OEE percentage can decline while actual performance, reliability, costs and output have improved.
  4. Are the “risks” of mandated budget cuts evaluated and positively addressed before actual cutbacks of budgeted maintenance activities are made? A 10%-across-the-board cutback can cause significant reliability damage unless the maintenance budget contains 10% discretionary spending on non-critical items. Arbitrary budgetary cutbacks happen all too often. PM and PdM activities get reduced, spare parts get outsourced and training gets slashed. Equipment breaks down more often, or downtime increases, costing the business more in higher unplanned expenses, as well as lost revenue and production. How would similar mandated across-the-board budget cuts be handled in safety and environmental areas?
  5. Does your skills and knowledge capturing process effectively prevent a “brain drain” (knowledge loss) as senior talent retires or leaves? Is this knowledge documented and disseminated as “best practices?” Whether previously trained or not, the years of expertise accumulated by senior, highly experienced maintenance personnel is an extremely valuable commodity in today’s era of skills shortages. If these skills and knowledge are allowed to leave a facility, how are newer employees to learn how to safely, efficiently and effectively perform the tasks of the job? Today, there is an especially powerful case for “procedure-based maintenance” versus “craft-based maintenance.” Procedure-based maintenance is based on captured, documented and refined “best practices” that form the basis of formal training and qualification. Craft-based maintenance assumes that given sufficient craft skills training, personnel can figure out how to perform almost any job task.
  6. Is reliability as important as safety, environmental, quality and human resources in your company’s strategic planning and execution? Imagine the competitiveness of a plant that paid little or no attention to such issues. Employees and working conditions would be miserable, communities polluted and customers highly disappointed. Based on any number of laws and regulations, and the fact that dissatisfied customers can take their business elsewhere, this type of operating policy would be intolerable. Why then, is shoddiness of equipment maintenance and reliability tolerated? The problem is that maintenance is generally unregulated and invisible to the paying customers.
  7. Are your operations and maintenance (O&M) costs per unit produced continually declining while the company’s return on assets (return on invested capital) improving? Not so long ago, if manufacturing and operating costs increased they were just passed on to the customer. As competition grew and global competitiveness mushroomed, businesses had to find ways to reduce costs. Cost-cutting programs prevailed in the 80s, 90s and even today. Some businesses discovered that they could eliminate “non-value adding” costs while others “eliminated wasted efforts and inventory to reduce costs.” Sustainability of cost-reduction efforts is of key importance! Changing work processes (methods and procedures) to more efficient ways often reduces costs. Successful plants have demonstrated continually declining operating and maintenance cost per unit produced. By using fewer capital assets or making the existing assets more productive their return on net assets also improved.
  8. Do your operations managers routinely attend “Maintenance and Reliability Conferences” (such as MARTS and MARCON) with you? Informed operations managers want to understand what it takes to improve plant and process performance and reliability, especially in capitalintensive operations. Senior executives striving to generate shareholder value truly understand the importance of a reliable operation. They read the journals and attend educational events to learn what it takes. This enables them to lead the operation from a high-reliability perspective and make informed decisions. Are you helping to keep them informed?
  9. Do your maintenance and reliability strategy and tactics focus on business-related results rather than on maintenance activities and initiatives in the hopes of improving performance? We are a culture of improvement initiatives, program-of-the-month and buzzwords. While some businesses have avoided these traps, many have bought them in big time. Major activities and initiatives typically consume large amounts of resources, including people, time and money. In resource-constrained businesses this is often a gamble for sustainable improvements to the bottom line: “Doing more with less.” An alternative approach is one of “focused improvement” that uses proven tools in ways that guarantee improvements and a solid and sustainable ROI, rather than plant-wide implementation. Focus on specific constraints, such as production bottlenecks, high maintenance costs, high downtime and problematic equipment that affect your business.
  10. Does the term “maintenance” in your company imply “sustaining a desired level of equipment and process performance (reliable equipment and processes)” rather than fixing things, painting things, moving things? We know that the best “value-added” work for our maintenance group is sustaining the desired level of performance of our equipment and facilities. Historically, however, “maintenance” has been side-tracked into “government jobs” for upper management, changing out lights and other odd jobs while the plant equipment suffered. Maintenance backlogs have become littered with hundreds of requests that seldom see the light of day because of reactive repairs, emergency work and top management’s pet projects. All of this leads to the perception (and the reality) that this is what “maintenance” is all about. What if we could demonstrate the bottom-line value of real maintenance, i.e. preventive and predictive maintenance, planned and scheduled maintenance, proactive maintenance and reliabilitycentered maintenance? What if we outsourced everything that interfered with it? (I recently was in a plant where production supervision and management are penalized if scheduled PMs are missed or deferred. The plant’s equipment is extremely reliable because of that management mindset.)

Creating a “reliability culture” that overcomes the inertia of the past, and overcomes the historical “maintenance mindset” is essential to improving the competitiveness of a capital-intensive business. It stands to reason that senior leadership must set the stage for improving reliability in the same way it leads improvements in safety, environmental, quality and human resource management. Policies are developed and communicated, new expectations set and accountabilities established for compliance to regulations, as well as conformance to principles promoted by a company’s senior leadership team.

How’s your company doing? Did you answer “yes” to the questions? Let’s consider what’s really at stake here.

If our maintenance programs, activities and talents were focused on the essentials of a competitive business, our plants and processes would be extremely reliable, less costly and more productive. Unfortunately, many of our business and governmental leaders still don’t understand the role that equipment and process reliability play in making us more competitive. While the U.S. has been ranked as “the most productive and competitive nation in the world” for 15 years in a row, we are still losing our edge. I am convinced that much of this is due to unreliable equipment and processes that stem from inadequate career education and training and ineffective maintenance.

Highly reliable plants result when there is a strong sense of partnership between operations and maintenance (i.e. teamwork focused on common goals). Teamwork is the fuel that allows common people to achieve uncommon results. What makes this work is the prerequisite: Leadership creates the framework for teamwork to exist and thrive. Let’s work together in our plants and facilities to achieve affirmative answers to these 10 questions. MT

Staying Productive & Competitive In Today's Food Industry


In an industry that’s widely consolidated, proudly independent Mt. Olive Pickle Co. has found that it is able to maximize uptime and minimize labor by using a new self-cleaning filter system that eliminates production stoppage.

As the largest privately held U.S. pickle maker, Mt. Olive Pickle Company understands it must operate more efficiently than the competition—all while turning out product of the highest quality.

The problem
Mt. Olive packs more than 90 million jars of pickles, relishes and peppers annually for distribution in more than 45 states. In one of its required processes, fresh pack product is run through a brine wash solution sprayed by nozzles at a salt bath. To keep the spray nozzles from clogging with bits of product debris washed off in the process, the brine wash solution must be filtered before each reuse.

According to Mt. Olive’s production manager, Steve Whitman, the filter bags the company previously used had distinct drawbacks. Depending on the product that was being run, filter bags on each production line had to be changed about once an hour, each time causing production to stop for about five minutes.

Furthermore, filtering efficiency could vary depending on how full the bags were, leading to potential spray nozzle blockage and line shutdown. To determine when to change filter bags, workers had to spend time and attention monitoring pressure gauges. “As the outlet pressure gauge dropped and the inlet pressure gauge increased, workers knew they needed to get in there and change their bag out,” Whitman says. Cleaning the strainers and changing out the filter bags by hand was a wet, messy job—and purchasing, storing, handling and disposing of the bags added to production costs.

The solution
Based on the recommendation of its salt bath supplier and its own research, Mt. Olive turned to the state-of-the-art Eco Filter system from Russell Finex, of Pineville, NC. The Eco Filter is a self-cleaning system that integrates directly into the pipeline and completely eliminates the need to change filter bags or clean filtration baskets. By means of a unique spiral wiper design, the filter element is kept continuously clean, ensuring optimum filtration efficiency. Because of its self-cleaning design, cleaning the filter between batch runs is quick and easy with minimal disruption during production changeovers.

“We no longer have to shut down production or babysit filter bags,” Whitman notes. “Because we’re getting all the particulate pieces of product out of the brine solution, we’re not stopping up our nozzles and we’re getting good brine flow into the system.”

Mt. Olive now uses a number of Russell Eco Filters in production. These have a unique Q-Tap valve that allows the sampling of freshly filtered material so quality can easily be monitored on the fly—without interrupting production. The filters also feature the Russell Filter Management System™, a technology that automatically opens the oversize discharge valve at a specified differential differential pressure or time interval. That means the system can be operated efficiently without operator involvement. Production is streamlined because the system automatically flushes and cleans itself when needed, and there’s no need to monitor, change or dispose of bags.

The benefits
Compared to the previous filter bags, these new filters are saving the company a substantial amount of downtime and labor. Whitman puts it this way: “We’ve had zero downtime with the Eco Filters. Because they’re virtually maintenance-free, they’ve helped us meet our production targets while saving labor.”

Companies like Mt. Olive are discovering that the Eco Filter fits neatly into their existing production lines, in many instances adding significant capacity without requiring excessive space. Because they are totally enclosed, these products also prevent outside pollutants from contaminating product and protect operators from any fumes or spillage. According to Russell Finex, users see considerable improvement in product purity, as well as throughput and waste elimination.

“With more production uptime and lower labor costs, the Eco Filters are helping us stay productive, competitive and grow into new markets,” concludes Whitman. “They’re part of our winning team.” MT

Addressing The Training Dilemma

Elegant Maintenance Managers will easily recognize and be able to capture the benefits that formal on-the-job training can provide for their organizations.

A successful trainer typically will employ two major principles in his or her work. The first of these is to ensure that trainees have the ability and talent for what their assignments will be. The second principle is to ensure that the initial training time is spent on what the trainees need to know. When these two principles come together, the result is an elegant training program. Unfortunately, in some operations, it’s difficult for managers to specify exactly what a trainee needs to know. That can be quite a problem for a maintenance organization.

What they need to know
Maintenance teams need to know how to conduct the business of maintenance. For example:

  • They need to know equipment locations and access requirements.
  • They need to know how to get their work assignments.
  • They need to know how to obtain tools and materials.
  • They need to know what safety practices to observe.
  • They need to know whom to communicate with and about what.
  • They need to know which documentation will be needed or helpful.
  • They need to know the status of the equipment, related equipment and overall operations.
  • They need to know how to properly complete paperwork to produce a meaningful record.
  • And they need to know when they have completed their task.

Regardless of their degree of technical knowledge, if maintenance personnel cannot understand all of the items above, they will be ineffective, possibly dangerous and the cause of additional corrective maintenance action(s). Keep in mind that about 50% of corrective maintenance tasks result from uncontrolled actions by the maintenance staff. This issue must be addressed before any other training is contemplated.

On-the-job training
A good way to start an effective in-house training program is through formal on-the-job training (FOJT) that incorporates an orientation training checklist for employees based on the documented maintenance process. “Formal” means that this type of on-the-job-training (OJT) is documented with an administrative control procedure and performance qualification sign-offs for each maintenance technician.

Informal OJT programs will not work because they are uncontrolled and undocumented to such an extent that there is no accountability and no record of accomplishment. They cannot withstand any kind of audit. Informal OJT programs degenerate into nonexistence depending on the interest of the individual who is supposed to provide the OJT—what gets passed on is anybody’s guess, and even that becomes less and less over time.

The in-house FOJT program is based on the specification for the conduct of maintenance (maintenance process procedures) that should be in existence if the management team has done its job. Remember, management is obligated to specify how it wants to conduct the maintenance function. That is the fundamental work of managers. This specification is the information the maintenance team needs to know.

What would the minimum set of management instructions on the conduct of the maintenance function look like? Let’s start with the process of maintenance. This would be the outlined statement of what one would look for during a maintenance action. The following information represents some very specific items about which management must instruct all maintenance personnel as part of their FOJT program.

The maintenance process…
Every individual and group (department, committee, team, etc.) at a facility is involved in many different activities, most of which involve multiple individual actions and interfaces with others both on and off site. The most effective way to ensure that personnel have developed a level of capability in execution of maintenance-related activities is for them to demonstrate that they understand the maintenance process and its key elements. This is best accomplished in-house through FOJT.

Note that maintenance process training applies to supervisors and other lead personnel, QA personnel and the engineering staff—especially the engineering staff. Engineers are responsible for providing the information necessary for the development of operating and maintenance procedures applicable to their system and equipment responsibility. When they design or specify systems and equipment for the enterprise, they must ensure that the operations and maintenance specifications, methods and training materials are included and available to O&M personnel.

Specifying awareness of maintenance process requirements to be part of the engineering staff ‘s responsibilities is necessary to ensure that the enterprise management staff understands the role of engineering in O&M activities. Ignorance of this fact, though, often lets the engineering staff escape its responsibility to contribute to the efficiency and effectiveness of the O&M staff, the reliability of the enterprise systems and equipment and the engineering staff ‘s share of the contribution to the bottom line. This needs to change.

Start by training the engineering staff in its responsibility for the maintenance process. While they’re at it, have the engineering staff also prepare and execute the installation, operational, and performance testing and acceptance for all engineering projects that affect the O&M function.


Task-complexity basis for maintenance training requirements…
The concept of work falling within the “skill of the craft” and not requiring detailed aids such as procedures, mockups, supervision or training has been around for decades. It implies that there is such a minimal capability expectation of personnel that special training is not necessarily required prior to task assignment. Thus, based on this premise, an individual should be able to execute certain tasks simply because they fall within the skill of the craft.

To establish the basic training level for the maintenance staff, one must understand what makes a task so complex that training or procedures would be required. In order to do this, one must understand complexity itself. Use the following definitions to determine the levels of complexity (i.e., the difficulty of the task):

  1. The job is complex if there are several interrelated things (e.g., parts, system interaction, equipment availability) that vary with time, and have uncertainty about whether or not these are the correct things that will come together to address the deficiency and complete the job as planned.
  2. The job is moderately involved if the uncertainty factor is missing.
  3. The job is simple if there is no uncertainty and no time variance on resource and equipment availability.
  4. The job may be considered as a minor maintenance category job, within the “skill of the craft,” if none of the above complicating factors apply (no uncertainty, no time variance and no interrelated things).

This concept is more understandable relative to developing training requirements and has a practical side when viewed from a maintenance planner’s point of view. It is obvious that a planner who can assess the problem situation in terms of the three complicating factors (several interrelated things, time variance and uncertainty) is a planner who appreciates the complexity of the planning to be done for a particular job.

Based on the determination of problem complexity, the planner determines if the work should be performed as a minor maintenance task, a moderately difficult task with routine planning such as pulling existing procedures and parts lists and making estimates based on established standards, or if a complex work plan will be required. Examining the checklists a planner would use for these determinations, one would have a pretty good list of things to cover in a FOJT program, as part of the maintenance process that maintenance technicians should follow.

These checklists must be developed by maintenance departments if they are to capture the corporate knowledge of their most experienced and most knowledgeable personnel. If the checklists are not developed, the corporate knowledge leaves when this valuable, irreplaceable human resource walks out the door—and the most valuable FOJT training resource also is lost. An example of a simplified planning checklist is shown in Fig. 1.

Skill of the craft…
Worker experience, expertise and qualification, as well as supervisory oversight and quality assurance, determine the scope of jobs that are in the category of “within the skill of the craft.” This important concept takes advantage of inherent workforce capability to function with minimal direction in performing tasks and using resources.

Maintenance craft labor should not require any additional training beyond the orientation and maintenance process training mentioned previously for the tasks in the following bulleted list. The implication is that your FOJT program should begin with technical subject matter beyond this level if your work force competency meets basic hiring level requirements.

Basic hiring level requirements should be defined in job descriptions. If no job descriptions exist, check the U.S. Department of Labor Website ( under the Directory of Occupations as a start to define basic hiring level requirements. Although specific situations will require specific decisions, the following list of typical maintenance planning tasks will help start the process. Interpret these items as those activities that fall within the “skill of the craft” for a basically capable maintenance operation. (Note: These items, along with non-critical maintenance tasks discussed later, also may be used for operator maintenance training in an autonomous training program adjunct to a FOJT program.)

  • Use non-specialized equipment in the taking of standard measurements.
  • Perform the minor fabrication of existing parts (standard geometries).
  • Perform routine rigging.
  • Perform non-critical welding within the qualification of the craftsman not requiring special permits.
  • Perform inspections in accordance with written guidelines or procedures.
  • Perform in-kind replacement of parts not requiring adjustment such as alignment or calibration.
  • Perform routine cleaning, adjustment or replacement such as for fittings, filters, belts or sealing surfaces.
  • Perform simple valve maintenance such as seat lapping, packing replacement and stem burnishing.
  • Carry out relamping and fuse replacement if problem is cleared and tagouts are in place.
  • Conduct lubrication rounds.
  • Perform surface corrosion cleaning, including dressing threads.
  • Trim levels in reservoirs and maintain refrigerant charges.
  • Perform soldering, wire wrapping, crimping, tube bending and installation.


Skill-of-the-craft consideration for contract or temporary workers requires more planning detail and supervisory control initially. As members of this part of the maintenance workforce become better known, they may be treated the same as in-house staff. They may come under the same level “skill of the craft” assessment if the contractor has a QA plan and training and certification program acceptable to the responsible facility organization.

Non-critical maintenance…
The above listing of basic tasks that should not require training beyond the maintenance process training provides guidance on tasks that fall within the skill of the craft. Coupled with the task level determination is the nature of the task per se in assessing the extent of the planning requirement for a given job. For maintenance tasks on facility electrical, mechanical or measuring and test equipment and associated parts, judge the task non-critical and within the skill of the craft when the following conditions are met:

  • The equipment is non-critical or the part affected is not critical to the operation of the equipment.
  • The equipment or part does not perform a regulatory required function (e.g., OSHA, FDA, EPA functions).
  • The inherent safety and reliability design of the equipment will not be affected.
  • The work doesn’t constitute a design change (e.g. material substitution, different model parts, fabrication that affects function or engineering properties).
  • Disassembly to the sub-assembly or part level is not required.
  • Welding will not be performed on equipment or parts as a means to restore original integrity.
  • Special permits and procedures such as burn permits, tag-outs and confined-space entry are not required.
  • Non-destructive examination or post-maintenance testing will not be required.

Examples of non-critical maintenance… mechanical

  • Perform valve maintenance such as packing adjustment, repair/replace hand wheel, clean, burnish, lubricate valve stem.
  • Perform pump maintenance such as packing/seal adjustment, lubricating, add/change oil and minor adjustments within given operating bands. 36-43
  • Stop leakage in piping connections, equipment fittings, seals and other pressure integrity barriers within specified torque values and consistent with gasketting and bolt tightening practices.
  • Perform replacement, adjustment or dressing of fastener hardware.
  • Perform all door maintenance, except on special doors such as pressure or watertight, fire barrier or security alarmed doors.
  • Perform general building and grounds maintenance, except that required by codes, standards or regulations.

Examples of non-critical maintenance… electrical

  • Perform relamping and fuse replacement for fuses under 10 Amperes rating.
  • Perform electric panel and instrument panel indication and status checks (visual).
  • Perform distribution wiring hardware inspection and adjustment of items such as fasteners, latches, and clamps.
  • Replace plug-in equipment in kind.
  • Perform routine checks such as meggering, continuity checks, fuse condition and measuring of circuit parameters for information only use.
  • Check security of grounding connections and clean and tighten as necessary.
  • Motors: Replace air filters, replace cover screws, replace screens.
  • Plant paging system: Repair or replace handles, knobs, etc.
  • Portable sump pumps: Repair or replace motor or wiring.
  • Doors, locks or latches: Repair or replace (except fire and security doors).
  • Telephone equipment: Install, replace or repair. Examples of non-critical maintenance… measurement & control
  • Perform calibration of simple devices.
  • Replace indicators such as bulbs or lamps.
  • Perform minor adjustments on recorders (e.g., pen, paper replacement).
  • Replace fuses.
  • Perform most maintenance on local gauges.
  • Clean and replace filters.
  • Perform functional checks.
  • Inspect and adjust cabinet hardware (fasteners, latches, locks).
  • Troubleshoot and make minor repairs on defective components after removal from service.

If your maintenance workforce cannot perform the non-critical items listed in the foregoing section—even after orientation and maintenance process FOJT—you may want to consider the following approach. Set up each of these non-critical items in the shop and “qualify” the maintenance staff in the non-critical areas before going on to the more complicated, technical tasks to be found in the vendor documentation under the recommended O&M requirements. Next, ask yourself how your company’s hiring practices let these individuals in the door—and now that they’re in, do they really have the aptitude for performing the maintenance function.


Getting beyond skill of the craft and non-critical maintenance…
The planner’s checklists mentioned earlier in this article are useful in establishing a sign-off list for a FOJT program that goes beyond the noncritical level of maintenance that a maintenance technician should know. This type of checklist represents a combination of the maintenance process training, “skill of the craft” knowledge and the general content of vendor O&M requirements.

Such a combination is the extent of an in-house FOJT program consistent with the aptitude of a properly hired maintenance staff and the knowledge and skill level they need in order to meet a minimum standard of performance at an industrial facility. Additional, specialized training may be required, but the need is now so precisely defined that the return on the training dollar investment will be maximized and easily presented for consideration in the budgeting process. Elegant Maintenance Managers will be able to show significant accomplishment in staff training within the training resource of the given budget, thus laying the groundwork and increasing the probability for their stake holders to increase the training investment in their area of responsibility.

The form shown in Fig. 2 is an example of the type of record generated in a FOJT program to establish a maintenance technician’s level of training and achievement on facility-specific systems and equipment—in this case, for an electrician. A “Prerequisites and Corequisites Checklist” documents the technician’s detailed knowledge of the maintenance process. (To request actual examples of a maintenance process document, the prereq/coreq checklist and other FOJT documents, visit and click on the e-mail address.)

A maintenance workforce that is hired based on skill levels as defined by organizations such as the U.S. Department of Labor, with some exceptions, has the aptitude for the job and likely the intelligence to learn. If a maintenance manager establishes the conduct of maintenance by way of procedures and practices, the groundwork is laid for a formal OJT program that will pay immediate benefits by addressing those corrective maintenance tasks caused by a lack of control of the maintenance function (about 50% of the CM tasks). Elegant Maintenance Managers have a well-defined maintenance process that serves as the basis for a training program in how personnel are to work in their respective enterprise. MT

Quincy Compressor Inc.

Quincy Compressor Inc. Quincy Compressor is a designer and manufacturer of reciprocating and rotary screw air compressors, vacuum pumps and a full line of air treatment components. The company has released a new line of compressed air system purifiers, condensate drains and high-tech modular desiccant air dryers to help industries comply with local environmental laws and produce high quality, clean and dry compressed air. The Q Mod heatless desiccant dryers deliver clean, dry air to the point of use by filtering liquids and adsorbing water vapor from a compressed air stream. Air is initially directed through a 0.01 PPM polishing pre-filter, removing untreated compressed air full of liquids, aerosols and mists. Quincy Condensate Purifiers use an environmentally responsible filtration process to remove condensate contaminates, like compressor lubricants including polyglycols, trapping them in a special filter cartridge that is lightweight and can be easily disposed of in accordance with local regulations. The replaceable cartridge system employs a carbon-free, oliophilic material in the purification process, and pre soaking is no longer necessary. Quincy energy-saving NO LOSS drains open only when, and for as long as, condensate is present. This allows the compressor(s) to run less often by not feeding leaks introduced by standard drains.
