 for improvement, managers need to understand their mill's status regarding current maintenance practices and benchmarks. In 1997, TAPPI's Maintenance and Mill Engineering Committee initiated an industry-wide survey of maintenance practices at pulp and paper mills throughout North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. . The purpose of the survey was to explore the prevalence and effectiveness of maintenance practices within the pulp and paper industry The global pulp and paper industry is dominated by North American (United States, Canada), northern European (Finland, Sweden) and East Asian countries (such as Japan). Australasia and Latin America also have significant pulp and paper industries. . The survey was divided into three sections: General Mill Information, Mechanical Maintenance Practices, and Electrical Maintenance Practices. Surveys were sent to 571 mills, of which 141 (25%) responded. This paper summarizes the data collected from the survey as interpreted by TAPPI TAPPI Technical Association of the Pulp and Paper Industry  Mill Maintenance Subcommittee members.

GENERAL INFORMATION

Mill profiles of survey respondents

The General Mill Information section of the survey focused on mill profiles (e.g., grades, production volume, number of employees, etc.) and select maintenance metrics (e.g., maintenance spending, scheduled and unscheduled unscheduled

This approach offers cost savings over routine or time-based preventive maintenance because tasks are performed only when , etc.) Table 1 lists the types of mills that responded to the survey. Many of the responding mills could be grouped by a single product line or grade. However, 39 of the 141 mills either reported producing multiple grades or did not match any of the 10 identified types. Mills ranged in tonnages from less than 10 tons/year to 1 million tons/year, and from less than 100 to greater than 1200 employees.

Maintenance budget and organization

Figure 1 depicts the total maintenance budgets for the responding mills. Maintenance budgets at 44% of the mills amounted to US$ 5 million per year or less. The remainder of the responding mills (56%) reported maintenance budgets exceeding US$ 5 million per year. As expected, labor expenditures represented a significant portion of the maintenance budget. Figure 2 shows that labor expenditures equaled 30% to 40% of total maintenance budgets at more than two-thirds of responding mills.

[FIGURE 1-2 OMITTED]

Respondents reported that the number of maintenance employees equaled an average of about 20% of total mill employment. This percentage dropped slightly from the 23% and 22% reported respectively for North American North American

Since earlier paper industry surveys, mills have made substantial progress in the areas of preventive maintenance The routine checking of hardware that is performed by a field engineer on a regularly scheduled basis. See remedial maintenance.

 (PM) and predictive maintenance (PdM). A decade ago, preventive maintenance was becoming a recognized best-practice, and predictive maintenance was seen by most as a "nice theory." In fact, the earlier surveys did not even mention PdM. However, with advances in sensor technologies and reduced costs of measuring and diagnostic equipment, PdM has become practical and cost-effective. In 1986 and 1987, preventive maintenance ranged from 9% to 22% of the total maintenance budget. In contrast, a few of the recently surveyed mills indicated budgets for both PM and PdM covered up to 100% of the total maintenance budget, with an average of nearly 4(1% (Fig. 3). The industry average for combined PM and PdM expenditures in 1997 was 52%, as reported by Gulati [3]. According to according to

 (CMMS) to track machine repair histories, schedule PM tasks, and provide a means of cost control. A survey conducted by Harrison [5] reported about 85% of mills have CMMS systems; the 1997 TAPPI survey showed this level to be unchanged. The Plant Maintenance Resource Center [6] reported industry averages of 90%.

Work order completion

A commonly used key performance indicator (KPI KPI Key Performance Indicator
KPI Kuwait Petroleum International
KPI Kiev Polytechnic Institute (Ukraine)
KPI Kernel Programming Interface
KPI King Pin Inclination (vehicle steering geometry angle) 
) for an effective CMMS system is the number of scheduled work orders completed on schedule. According to Smith and Black [7], for an organization with "best maintenance practices," this KPI should be 90%. As shown in Figure 4, very few mills reported such high values. Of the respondents, 83% said they documented findings when scheduled PM and PdM were completed and 88% of mills maintained repair histories for critical equipment. For an organization to be considered world-class, these values need to be near 100%.

[FIGURE 4 OMITTED]

Tracking and controlling unscheduled downtime

Most mills ranked quite high in their ability to control unscheduled downtime, with 72% of responding mills having less than 5% unscheduled downtime and 51% of the total reporting less than 3% (Fig. 5). Not illustrated in the charts, 9% of mills indicated the amount of unscheduled downtime was increasing, whereas the vast majority (91%) reported it to be declining. Mills have been tracking unscheduled downtime for a long time, with 34% having more than 10 years of records. Surprisingly, most mills were seemingly lax in follow-up analysis. Only 26% of the responding mills had a system in place to analyze the causes of downtime and initiate corrective actions A corrective action is a change implemented to address a weakness identified in a management system. Normally corrective actions are instigated in response to a customer complaint, abnormal levels if internal nonconformity, nonconformities identified during an internal audit or . Only 12% of mills indicated the amount of unscheduled downtime was increasing, whereas the vast majority (88%) reported it to he declining.

[FIGURE 5 OMITTED]

Operator-performed maintenance

The first line of defense for avoiding reactive maintenance is the operator. If properly trained and with adequate experience, operators can notice "out of the ordinary" changes in a machine and can perform minor maintenance operations (e.g., cleaning, oiling, tightening, and inspection). These operator-performed routine maintenance functions can mitigate system failures and postpone the need for major maintenance until it can be properly scheduled. Under the Total Productive Maintenance (TPM (1) See TP monitor.

) method, operator involvement in the overall maintenance strategy is mandatory. Figure 6 shows that significant operator performed maintenance was practiced by only a small traction of the mills surveyed. These numbers can be compared to those reported by Harrison [5], the averages of which range from 6% to 29%. For a world-class organization, Connaughton 181 reports 30% of minor maintenance work is accomplished by production personnel.

[FIGURE 6 OMITTED]

MECHANICAL PRACTICES

The Mechanical section of the survey covered select programs and practices used by mills for maintaining mill equipment. Programs and practices included vibration analysis, lube oil analysis, vessel inspections, and alignment checks. The survey also asked mills to provide input on the sources of maintenance that caused repair problems in the mill.

Sources of repair work

Nearly two-thirds (62%) of those responding reported mechanical wear as the greatest source of maintenance (Fig. 7). Corrosion was the second leading cause of mechanical maintenance, cited by 38% of respondents. Abuse ranked third at 33%. Only 21% of mills cited lack of preventive or predictive maintenance procedures and 13% cited vibration. Fewer than 10% of respondents noted erosion, secondary maintenance, or impact as causes for mechanical maintenance.

[FIGURE 7 OMITTED]

Mechanical programs and practices

The survey requested comments on the use of specific mechanical maintenance programs and practices. Respondents selected from 19 different programs, including vibration analysis, noise inspections, lube oil analysis, alignment checks, etc. The survey also asked which programs provided the best value and the least value. Respondents could identify multiple programs used by their mills and could also select multiple programs as providing the best or least value. Table 2 lists the top five best value programs. Table 3 lists the five programs ranked by respondents as least valuable. There appeared to have been a correlation between use of a practice and perceived value of the practice. For example, of those mills reporting to use vibration analysis, 97% claimed the use of vibration analysis provided a best value and 1% claimed it provided a least value. Lube oil and wear analysis was the second best valued program at 64%. In contrast, only 5% of the mills that followed a documented foundation inspection program considered it a "best value."

, it was also the program reported as providing the least value by 60% of mills following the practice.

Vibration analysis

The survey sought further details on vibration analysis programs. As expected, mills paid most attention to equipment in the paper machine building and stock preparation areas. An average of 1939 vibration points monitored in the paper machine area was reported by 90 respondents. However, the range in the number of points monitored varied greatly--from a low of 10 to a high of 11,730. Twelve mills reported monitoring 5000 or more vibration points in the paper machine and stock preparation area and 13 mills reported monitoring 100 or less vibration points. The survey asked respondents about the frequency of vibration monitoring. Figure 8 shows the results. Of 131 responding mills, 54 (41%) use a monthly routing interval, with 80% of mills monitoring vibration points on a monthly or shorter frequency.

[FIGURE 8 OMITTED]

Seventy-nine percent of mills reported they establish a signature baseline for new equipment, while 42% reported they outsource vibration analysis activities.

NDE Near Death Experience
NDE Nondestructive Evaluation (ultrasound material evaluation) 
). Figure 9 also shows the most frequently used NDE methods. The most favored of NDE--used by 78 (86%) of 91 responding mills--was ultrasonic testing In ultrasonic testing, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. . Other popular NDE methods were magnetic particle, performed by 34 mills (37%), and liquid penetrant pen·e·trant

Lube oil sampling

Figure, 10 shows the frequency of lube oil sampling. Two-thirds (66%) of respondents reported performing lube oil sampling on at least a quarterly basis. More than one-third (37%) of respondents also reported using ferrography at their mills.

[FIGURE 10 OMITTED]

Drive coupling alignment

The survey asked mills about alignment of drive couplings. Most mills (74%) had migrated to laser alignment by 1997. The remaining mills (26%) indicated they used dial indicator Dial indicators are instruments used to accurately measure a small distance. They may also be known as a Dial gauge, Dial Test Indicator (DTI), or as a "clock".  and feeler gages Gages

 as their method for aligning drive couplings. Mills were given four choices as their source of alignment specifications: OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and , local mill, consulting, or corporate engineering. Most mills (60%) used specifications generated at the local mill level. Thirty percent of mills used specifications provided by OEMs. Less than 10% of respondents indicated they used specifications provided by either consultants or corporate engineering.

Impact of PM and PdM on unscheduled downtime

Most respondents indicated that PM and PdM programs had some positive impact in decreasing unscheduled downtime. PM and PdM programs and activities significantly decreased unscheduled maintenance downtime for 111 of 137 respondents (81%). TWenty-four of 137 respondents (18%) reported that PM and PdM programs and activities had only a marginal impact on decreasing unscheduled maintenance downtime. Only 1% of the mills reported that mechanical preventive and predictive maintenance procedures had no effect on decreasing unscheduled maintenance downtime.

ELECTRICAL PRACTICES

The Electrical section of the survey queried mills on their use and perceived value of twenty-two testing and diagnostic procedures. It also captured the frequency of certain procedures, the age of mill electrical systems, and the perceived impact of PM and PdM on unscheduled mill downtime.

Electrical programs and practices

Table 4 lists the top five best value electrical maintenance programs. Walk-down inspections was the next best value program (43%). Table 5 lists the five programs that respondents felt gave the least value. As observed with mechanical maintenance practices, the increased use of a specific practice generally correlated with its perception as a "best value."

Age of mill electrical systems

The average age of a responding mill's electrical system was 20 years. Although most mills (84%) reported the average age of their electrical systems at 30 years or less, 62% of mills reported having at least one electrical system greater than 30 years old. Nine mills reported having at least one system greater than 70 years old.

Frequency of electrical system testing (testing) system testing - (Or "application testing") A type of testing to confirm that all code modules work as specified, and that the system as a whole performs adequately on the platform on which it will be deployed.  and diagnostics

Table 6 captures the frequency of use of some of the best-used practices. Eighty-six percent of mills reported using infrared testing at least on an annual basis. Although load testing Load testing is the process of creating demand on a system or device and measuring its response.

(This inconsistency may be partially attributable to respondents' interpretation of the definition of "regularly"). More than two-thirds (70%) of mills using calibration of protection relays reported performing it at two- to five-year intervals. Over one-half of mills using transformer oil Transformer oil is usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage  analysis reported performing the analysis on an annual basis.

Infrared testing

Of the responding mills, 90% were using some level of infrared testing as a preventive maintenance technique. Of those 127 respondents, almost all used this practice in motor control centers (98%) and on high voltage switchgear According to IEC, high voltage switchgear is any switchgear and switchgear assembly of rated voltage higher than 1000 volts.

 (91%). While these numbers varied by equipment type, only 44% of respondents actually used infrared testing on "all" of the listed categories (mainly due to the low percentage of mills using this technique on powered equipment). Most of the mills (84%) had this service performed by an outside contractor outside contractor ncontratista m/f independiente .

Impact of electrical preventive and predictive maintenance on unscheduled downtime

The results mirror those found for mechanical-related preventive and predictive maintenance activities. Most respondents indicated that PM and PdM programs had some positive impact in decreasing unscheduled downtime. PM and PdM programs and activities significantly decreased unscheduled maintenance downtime for 92 of 131 respondents (70%); 36 of 131 respondents (28%) said such programs and activities only marginally decreased unscheduled maintenance downtime. Only 2% of the mills reported that electrical PM and PdM procedures had no effect on decreasing unscheduled maintenance downtime.

CONCLUSIONS

Mill managers and maintenance managers can use these results to broadly assess their mill maintenance practices in certain areas. They can also compare results to international surveys reported by Arommaa and Klarin [9]. While this survey's results do not suggest specific performance measures, managers may want to look into areas where significant gaps exist between their individual mill maintenance practices and the survey results. However, caution and judgment are required when comparing a single mill's performance or practices with the survey results.
