The pulp and paper industry in Western Canada is in a period of unprecedented
change. Against a background of poor markets, rising costs, aging plants, a
shrinking fiber supply, and unceasing pressure from owners to improve returns,
managers are being forced to take actions that could not have been contemplated
as little as a decade ago.
This article describes the situation at Fletcher Challenge Canada
Ltd.’s Crofton, B.C., pulp mill, and the actions taken to increase
production by implementation of a cost effective preventive maintenance
(PM) program. To be successful, this change required levels of accountability
and discipline with which the employees were unfamiliar, and an important
part of the implementation process was to build a commitment to the
inspection process through involvement and introduction to a culture
of continuous improvement.
MILL BACKGROUND. The Crofton mill was
built in 1957, with expansions in the early 1960s and 1980s.
These expansions included a new pulping line and the construction
of three newsprint machines. Under the ownership of British Columbia
Forest Products (BCFP), the mill, in conjunction with BCFP sawmills
in the area, operated as a fully integrated forest enterprise.
Fletcher Challenge Canada Ltd. was formed in 1988 when Fletcher Challenge Ltd.
purchased controlling interest in BCFP. BCFP owned Crofton pulp and paper,
Mackenzie, B.C., pulp, and a number of sawmills and forest interests. During
the late 1980s and early 1990s, the sawmill and forest interests where sold
off as FCCL concentrated on the pulp and paper business.
Crofton Pulp is one-half of FCCL’s operations. Today, the Crofton pulp
mill is a two-line kraft mill producing 1,060 mtpd of northern bleached sulfite
kraft (NBSK) pulp, of which 150 mtons are used for paper production. The operation
is a closed union shop and the B.C. labor laws have, and still do, provide
considerable security for the union.
During Crofton's early years, the earnings from all operations provided a high
return, and, to protect the operation in the face of considerable union pressure,
many restrictive work practices were accepted by the management of the time.
Also, union contracts were very lucrative, with employees being paid much higher
wages than those in similar occupations outside the industry. Most employees
felt that their employment was secure until retirement.
In the last three decades, however, the industry has become increasingly subject
to the effects of business cycles, and it has become increasingly apparent
that the habits of the past cannot continue. In addition to cyclic pressures,
there are long-term changes to the business environment that have made change
inevitable–the most significant being product price. In recent years,
the selling price of kraft pulp has maintained a low level. There are also
negative pressures on demand for NBSK resulting from new papermaking technology,
and the supply of alternative, low cost products has rapidly expanded.
While the above factors impact the whole industry, B.C. faces its own unique
challenges. These include aging mills, unusually inefficient work practices
supported by labor legislation, increasingly restrictive forest legislation,
high property taxes, strong local environmental pressures on logging operations,
and increasing competition for available fiber. The end result for the Crofton
mill has been poor financial performance and great concern for the future of
the enterprise.

CORPORATE REACTION TO THE ECONOMY.
In 1995, it became clear to FCCL that the traditional, conservative
approach to mill management would be unable to achieve the results
required to maintain investor confidence. Because of this, many
changes were made, including the division of the company into
separate and independent pulp and paper companies. The pulp company "Pulpco" now
includes the kraft operations at three of FCCL’s B.C. mills–Crofton,
Elk Falls and Mackenzie. Also, management of the three pulp mills
was consolidated.
In addition, FCCL’s Pulpco changed from an engineering/operations focus
to a business/performance focus. It also moved from a centralized organization
to an operating-team-based mill organization, including the elimination of
the central maintenance department. A totally new management team was placed,
and there was increased accountability for meeting established and measured
performance targets.
Other changes included staff reductions and hourly work force reductions. There
were also strong efforts made to reduce restrictions permitted under the old
labor agreement, culminating in a nine-month strike. However, flexible work
practices were introduced, and changes were made to traditional crew responsibilities,
as well as to lines of progression.
FCCL’s Pulpco also replaced its computerized maintenance management system
(CMMS) and outsourced its materials management to the paper company side of
the business. In addition, it began a major project to identify and pursue
operational improvement opportunities known as Opsim (OPerationS IMprovement).
The changes were made over a short time period, which resulted in considerable
unrest and feelings of insecurity by all employees. While the changes are showing
positive results, probably as the result of a very strong and clear message
that survival is at stake, there have been some negative effects, including:
- Placement of staff in positions where their skills do not necessarily
match the requirements of the job
- Loss of many good systems (for example, the lubrication program
and procedure manuals)
- Acute limitations on some resources required to advance the change
process
The impact of these effects is being minimized through strong efforts
to communicate the state of the business and the progress of improvement
initiatives, and through similarly strong efforts to gain commitment
of the work force to support the change process.
PREVENTIVE MAINTENANCE OPPORTUNITY. It
has long been recognized that the Crofton kraft mill did not
operate as reliably as it could, and that this was causing a
considerable loss of production. However, no concerted effort
had been made to quantify the loss.
During the 1997-1998 strike, the Opsim project was started, with carefully
selected teams of people from all three mills assigned to investigate various
aspects of each mill's operation. One of these was Crofton's "output" team,
which studied opportunities to increase mill throughput.
An invaluable tool for this process was the detailed information collected
in the mill's production-loss reporting system, which had been in use for about
18 months prior to the start of the strike. The data for this reporting system
is collected and entered by the operating shift foremen, and in the 1996-1997
base year, 5,000 entries were made, with each entry recording the cause of
the loss and current mill operating details (grades, etc.) at the time of the
loss.
Analysis of the production loss data for the base year showed clearly that
the single largest opportunity for improvement was in increased equipment uptime,
and that relatively few items of equipment contributed to most of the production
losses. Of the 5,000 entries, over 900 reported losses from 400 equipment breakdowns
(many resulted in more than one entry because they affected more than one area
or lasted longer than one shift). The total production lost due to breakdowns
was 32,000 mtons, or about 10% of the mill's capacity.
In addition, further analysis showed that only 87 breakdown events caused 80%
of these losses.
ACTION PLAN FOR REDUCING BREAKDOWNS. A small implementation team was
established to define the loss reduction goal and to develop an action plan
to address the problem of breakdowns. The goal was defined as "implement
an improved PM system to save $3.54 MM per year by July 1999." This represented
a 30% reduction in losses from the base year.
This team started work at about the same time as the Crofton mill resumed operation
after the strike (April 1998), and it quickly became apparent that mill startup
and operating priorities were threatening achievement of the team's goal. Three
immediate actions were then initiated:
- Create a new, full-time position of maintenance systems specialist,
with the dual roles of managing the PM process and administering
the new CMMS
- Select and retain a consultant to provide guidance and resources
for PM implementation
- Select a team of hourly employees to build the new PM process
under the guidance of the maintenance systems specialist and the
consultant
Howard Turner, a maintenance foreman with past experience as a millwright,
machinist, and also as a management trainer, was eventually selected
for the new position of maintenance systems specialist. In addition,
a team of hourly tradesmen and first-line supervisors was established
to choose a consultant, resulting in the selection of Idcon.
A posting for the hourly employees needed to work with the maintenance systems
specialist resulted in eight applications from various trades. All applicants
were selected and trained, with the understanding that only three would be
released to work on the project at any one time. Since no operators or electricians
had applied, suitable candidates were approached and they volunteered to work
with the team.
To increase the team's mechanical expertise, two millwrights who were on sick
leave were approached and agreed to assist. Both became core team members and
brought with them essential computer and inspection skills. One of these millwrights
developed a new Microsoft Access database, now known as RoutePro, for all inspections,
avoiding the need to purchase a separate system. Unfortunately, the new CMMS
did not have the capability of producing good inspection route sheets, but
it generated the work orders to initiate inspections.
DESCRIPTION OF THE NEW PM SYSTEM. A
comprehensive PM system had been in use for some time, but the
repetitive tasks were largely inspections and component replacements
requiring plant shutdowns. With the elimination of the central
maintenance department, reduction of staff and hourly employees,
introduction of a new CMMS, and many people working in areas
that they were unfamiliar with, many of the components in the
old PM system were lost. There was also a vibration measuring
and analysis program, with one technician, supported to varying
extents by area millwrights. This system was not lost, but, because
of manpower restrictions, it became reactionary rather than proactive.
The initial intent of the implementation team was to extend and formalize the
existing PM system and to balance the PM workload to the available manpower.
However, after initial discussions and training from Idcon, the team agreed
that the emphasis should change from shutdown inspections to a program of ongoing
equipment care and monitoring, using the principles of Idcon's "Preventive
Maintenance/ Essential Care and Condition Monitoring" process.
To achieve the greatest benefits in the shortest time, inspections of the "top
87" items of equipment were the first to be implemented. The key components
of the new process are:
- inspection routes set up to minimize walking time
- four monthly routes for each area team
- generic equipment component inspections
- condition monitoring standards
- automatic worker order generation system in the CMMS
- reporting process to track adherence to the inspection schedule
and for follow-up on corrective maintenance work orders that originate
from PM inspections
The maintenance systems specialist also took the initiative to rebuild
critical lost systems, such as the lubrication and filter replacement
programs. A new lubrication system, Lube-it, is now in use and is certainly
contributing to the reliability improvements to date.

IMPLEMENTATION OF THE PM PROJECT. The
implementation process started with a visit from Crofton’s
consultant, who reviewed the goals and objectives for the mill’s
PM program and developed action plans to achieve them. This visit
gave the consultant a chance to view the situation first hand,
to meet the people that would be involved, and to take equipment
photos that would be use to customize the training session.
Next, the mill posted for PM implementation team involvement from hourly employees
and directly asked others, such as operators, in order to get a fully cross-functional
team. This was followed by a four day training session for the team and maintenance
systems specialist.
During training, half the time was spent in the classroom and the other half
was spent in the field doing what had been taught. This session not only covered
the tools and techniques used to perform the inspections, but why the inspections
were necessary and what the benefits were from doing them. In the field, the
PM team and consultant created standard inspections for some of the equipment
on the mill’s critical list, which was made up of the 87 items that caused
80% of the production losses.
The PM team’s next step was to divide up all mill production equipment
into the three operating team areas, starting with the cooking area, since
it was the location of the Crofton mill’s biggest losses. The first route
developed was the critical equipment (as defined by production losses due to
equipment breakdown) for the cooking area organized into a walking route. While
walking the route, the team noted each component in the order it came upon
it, designating the component, for example, as motor -AC, coupling-Falk, pump-centrifugal,
etc. In total, the team noted 77 standard components mill wide. With the help
of Idcon’s database, the team developed a list of standard inspections
for each component.
Each of the three operating team areas was further divided into four geographical
areas. The equipment in each area would become a monthly route, with one route
done each week. Every piece of production equipment would be inspected in detail
once a month by the PM inspector. The team also developed four less detailed
routes for the field operators. Because they work four days on/four days off,
they would perform one route on each day of their tour. Each piece of equipment
would be checked by operators every two days.
The team also developed a detailed Condition Monitoring Standard Document for
each of the 77 standard components. This is a plastic covered reference document
that explains in detail how the equipment works and how to perform the inspections– complete
with pictures and reference points. The document also identified any safety
or related information that the inspectors might require. In addition, it was
used as a training aid for new inspectors.
PERFORMANCE TRACKING. Overall performance is measured simply as a reduction
in the cost of breakdown-related downtime as compared to the base year. A fixed
contribution per mtons of production is assumed for this calculation, so the
results are directly related to the reduction in lost tonnage.
Initially, a derived performance improvement measurement based on the number
of inspections completed and the anticipated reduction in annual losses was
used, but this number gave rise to too much subjective interpretation.
Individual team performance is measured by compliance reporting of percentage
completion of PM inspections as reported on the mill’s CMMS. The team
is in the process of development of PM key performance indicators (KPIs) for
each maintenance leader. Progress on the PM program, as with all Opsim projects,
is reported to the mill manager each month.
PROJECT RESULTS AND FUTURE PLANS. While
the project was to be finished July 30, 1999, and good results
have been achieved to date, there are still some outstanding
activities and issues that require special effort. By accomplishing
these, the mill hopes to start along the path towards a culture
of continuous improvement.
The Crofton pulp mill is seeing positive changes in plant availability, and
while the PM project can not take all the credit for this, it is definitely
contributing to the improvement process. The PM project’s goal of 30%
reduction in lost production due to equipment breakdown (11,000 mtpy) has been
reached (Figure 1). Benefits gained will be maintained through a process of
measurement and reporting, and through recognition and rewards for improved
plant reliability.
Some of the outstanding issues include final balancing of manpower availability
and inspection frequencies, as well as completion of inspection routes–especially
piping, electrical, instrument, and operator check lists. Improved alignment
and balancing standards, expansion of best operating practices, and completion
of development for PM KPIs are also targeted. The mill wants to develop detailed
rebuild procedures, installation procedures, and a process for root cause analysis.
In addition, the Crofton mill plans to continue working with the operating
team leaders to establish the PM inspections as mandatory routines. There are
plans to integrate the PM inspection program with other related activities,
such as planning and scheduling, vibration analysis, loss prevention (incident
investigation and follow-up), and other inspection programs. Eventually, all
responsibilities of the PM implementation team (including performance reporting)
will be transferred to the area operating teams.
