Maintenance Program Reduces Pulp Loss at Fletcher Challenge Canada
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.

mill is a two-line kraft mill producing 1,060 mtpd of NBSK pulp, of which
150 mtons are used for paper production.

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.
