Introduction to Plant Maintenance

What?

Planning, processing and documenting of repair tasks for

corporate operation and production resources.

Why?

To maintain the various resources of plants in order to ensure the

smooth and efficient working.


4/60


Activities under Plant Maintenance :

Inspection

All measures which establish the actual condition of a technical system

Preventive maintenance

All measures which maintain the ideal condition of a technical system

Repair / Breakdown Maintenance

All measures which restore the ideal condition of a technical system

Maintenance Projects All Measures required to make modifications or add to existing

technical system

Planning Organization Structuring

Centralized Maintenance Planning

The company has several maintenance plants, however, only one plant

in which maintenance planning is performed.

Decentralized Maintenance Planning

The company comprises several maintenance plants. Each plant

performs its own maintenance planning.

Partially Centralized Maintenance Planning

The company comprises several maintenance plants. Some of the

maintenance plants perform their own maintenance planning, others do

centrally.


6/60


Structuring

Maintenance Plant

The maintenance plant for a technical object is the plant at which it is

installed

E.g. Clarification plant C1 is located in plant 0001. Plant 0001 istherefore the maintenance plant for the clarification plant C1.

Maintenance Planning Plant

The maintenance planning plant for a technical object is the plant in

which the maintenance tasks for the object are planned and prepared .

E.g. The maintenance plant for the clarification plant C1 is plant 0001.

Plant 0001 does not perform its own maintenance planning. It is

assigned to plant 0002 . The maintenance planning plant for the

clarification plant C1 is therefore plant 0002.

Functional location

Is a multi-level hierarchical breakdown structureof machinery. Individual equipments can be

installed within this hierarchy.

Provides a context for executing and recording

maintenance tasks.

Provides a framework to monitor and track costs.

Provides a framework to monitor and track

location of equipments.




Equipment

Equipment is a uniquely identifiable physicalmachine, upon which work can be carried out and

about which costs and history can be recorded.

More than one piece of equipment can be installed

at a functional location.

Equipment should be created if:

Individual data is to be managed for the object (for example, year of

construction, warranty period, usage sites).

A record of the maintenance tasks performed for the object must be kept (e.g.

for insurance or legal inspection purposes).

Technical data on the object is to be collected and evaluated over a longperiod of time.

The costs of maintenance tasks are to be monitored for the object.

Records of usage times at functional locations are required for the object.

Documents and BOM follow an equipment irrespective of installation location.

Equipment vs. functional location

Technical object Functional location Equipment

This is relatively stable,

may not be changed inyears

This is laid into a certain

position and it can bechanged more often

Example Turbine Motor

Oil pump

Shaft




Equipment design

If the object at a functional location will never move physically, suchas a storage tank, it is not necessary to set up an equipmentrecord. Any work can be raised against the related functionallocation.

Determine movable and non-movable machines to see whetheran equipment needs to be created or not.

Equipment can be installed on or dismantled from either a superiorequipment or a functional location.

Equipment needs to be installed on the correct functionallocation during conversion.




Bill of material

A maintenance Bill Of Material (BOM) is a structured list of the components(i.e. functional location or equipment) or an assembly (material).

The BOM contains object numbers of individual components together withtheir quantity and unit of measure. The components can be Stock orNon-Stock Spares or Assemblies, which in turn can be described usingmaintenance BOMs.

Specifies only maintenance relevant components.

Maintenance BOMs are primarily used for the following purposes:

Structure description

A maintenance BOM describes the structure of a technical object or material.

Using maintenance BOM you can specify exactly where maintenance tasksare to be performed on a Technical Object.

Assignment of spare parts

A maintenance BOM is used in PM to assign spares for a technical object fordocumenting and choosing materials.

Bill of material design

Use of generic BOMs (i.e. Material BOMs) rather then specific

functional location or equipment BOMs.

Material BOM - A generic BOM is applicable to one or many

equipments or functional locations. By using generic materialBOMs, maintenance is simpler since there are less BOMs.

Spare Parts will be in SAP as part of the BOM.

Material need to be defined before the BOM can be built.




Document and links

Offers document references and an easy access to related

documents for

functional locations,

equipments andmachine models (materials).

Access within master data, notifications and work orders.

Requires organized servers and folder structures




Material master

Maintenance relevant materials are for example:

spare parts

assemblies

common machines

All data of a material is integrated in one master record.

Integration also enables the master data to be used jointly by

purchasing and other areas like inventory management and

invoice verification.

In maintenance processing materials are used e.g. in ordering and

reserving spare parts.

Catalogues

Maintenance catalogues are groups of standardized codes used to report

technical history for work that has been performed.

There are various types of catalogues that can be defined in SAP. Typical

ones are:Object part catalogueallow the user to specify the specific part of a piece of

equipment or functional location that work is being requested or performed

for.

Fault code catalogueallow the user to specify the type of damage that has been

observed.

Cause code catalogueallow the user to specify the root cause.

Activity code catalogueallow the user to specify what activities were carried out

to fulfill a work request or to document work that was carried out.




Catalogues

Technical history associated with the repair and maintenance of

specified equipment provides a basis for monitoring plant and

equipment integrity, such as:

Frequency of failure

Failure grouping and analysis

Impacts of maintenance strategies (planned Maintenance, corrective

maintenance, run to failure)

Component reliability analysis

Support to report analysis

Standardized codes enable benchmarking.

Description of the process

The corrective maintenance planning process

Starts with creation of notification,

either a fault report

or a maintenance request,

ends with the creation of a maintenance work order,

includes several decision points whether to

create maintenance work order,

postpone to later or

cancel request.

Maintenance Order

What is a Maintenance Order ?

It is a detailed planning of the maintenance task which has to be

performed.

Why Maintenance Order ? Plan tasks in detail with regard to type, scope, dates and resources.

Monitor the execution of tasks.

Define rules for account assignment, settlement and budgets.

Enter, assign and settle the costs which arise from tasks.


29/60


Information from the Maint. Order

Location or Equipment needing the repair ( inherited from the

Work order planning and scheduling

Starts after the maintenance work order has been created and finishes

when the work order is scheduled to execution.

The process includes planning of material

stock material from the warehouse

non-stocked material to be purchased for the order

and planning of resources

own resources

external services to be purchased.

The scheduling part co-ordinates timing of work orders.

Measuring point


51/60



Measuring point

Are used to enter measurements and counter readings (quantitativeoperating data) for technical objects.

Measuring point is a physical and/or conceptual location at which a

condition is described.

Accumulated totals can trigger a PM Notification or PM Order.

Typical situations of use are:

Counter-based maintenance (preventive maintenance every 1000

production hours).

Condition-based maintenance (preventive maintenance when brakepad minimum thickness has been reached).

Condition of the object is needed to be documented at a particular pointof time (e.g. legal, health and safety reasons).

Measuring point


52/60



Measuring point

Measurements and counter readings are represented in SAP as

measurement documents.

Measurement and counter reading data can be entered into SAP

e.g.:Manually using SAP user interface.

Manually using browser and transferring it to SAP via Internet.

Semi-automatically using barcode reader and transferring it from

external system to SAP via interface.

Automatically transferring it from external system to SAP via interface.

Refurbishment processRefurbishment Process



57/60




Refurbishment

The refurbishment process starts with creation of a refurbishment work

order for a material number and

ends with completion of the work order.

Planning and scheduling of the refurbishment work order follows the

normal planning and scheduling process flow.

After the refurbishment work has been executed the refurbished

material may be put to stock.

For refurbished equipment the status is changed.

Additional details


58/60



Additional details

Refurbishment cases can be handled in different ways:

Equipment with normal PM work order, where equipment does not

have SAP serial number. These are major machines.

Smaller machines and major components with refurbishment work

order. These have normal material number with split valuation andpossibly a serial number.

Smaller low value components with standing work order and zero stock

value.

Before the equipment is refurbished, its status will be changed towaiting to be refurbished.
