3. Policy

The following subsections contain the policy statements these are the key elements in the

drive towards achieving the goals determined in the corporate Vision and Maintenance

Mission statements.

3.1 Policy Review Period

The Maintenance Policy should be reviewed every 3 years.

3.1.1 Responsible Policy Holder

The responsible person and owner of the Policy will be the Assistant General Manager

Production (AGM-P) the current holder‟s name will be contained in the Policy. The

Technical Custodian for the Policy will be the Maintenance Division.

3.1.2 Revisions, Additions and Deletions

These can be added to the Policy at any time subject to approval of the responsible person.

3.2 Integrity

Maintenance policy, procedures and tasks will be implemented such that the integrity of the

installation(s) is not compromised.

3.2.1 Independence of Integrity Division

The Integrity Division and its personnel will remain independent of the asset. To act as

“Third Party” for maintenance activities.

3.2.2 Inspection Generated Work Orders

All work scopes generated by the Inspection Engineer will be implemented by the

maintenance department in the timescale and content agreed with the Inspection Engineer.

3.3 People

All maintenance personnel will complete a role based competence assessment. This will

ensure that the correct skills and experience levels are maintained.

3.4 Codes and Standards

All work will be completed to the appropriate ADMA and shareholders codes and Standards

or applicable International Standard.



MAINTENANCE POLICY


10


3.5 Reliability Focused Methodology

All maintenance activities will be geared towards the goal of increasing the reliability and

efficiency of plant and equipment. To achieve this goal existing processes and procedures

will be reviewed or replaced as necessary.

In order to gather the data that allows the reliability and efficiency of equipment to be

calculated the main information sources for data collection is:

a. Computerised Maintenance Management System (CMMS)

b. Operator log sheets.

For dependable data from the CMMS

a. The correct configuration of the CMMS hierarchy and associated equipment data.

b. Maintenance personnel entering the data trained in the use of the CMMS and of the

importance of correct data entry.

3.6 Criticality

The maintenance requirements for each process system and equipment within the system will

be reviewed on a criticality basis recognising the 5 Year Business Plan.

Criticality is defined as a relative measure of the consequences of a failure, its mode and its

frequency of occurrence. A criticality analysis is the procedure for ranking potential failure

modes according to the combined influence of severity (the degree of damage that could

ultimately occur) and the probability of occurrence or expected loss frequency.

3.7 Maintenance Key Performance Indicator Drivers

To manage maintenance effectively and to support a continuous improvement culture, a set of

objectives must be defined. A performance management system uses Key Performance

Indicators (KPI‟s) as an effective means of summarizing key information for:

a. supporting the establishment of targets for performance

b. comparing performance with objectives

c. clearly demonstrate the cost and value of maintenance.

3.8 Management of Change

Any change as defined in the Management of Change document will be managed through the

“Plant Modification Request” (PMR) procedure.



MAINTENANCE POLICY


11


3.9 Budgets

Maintenance Budgets will be developed on an accepted frequency. This is the asset high

level cost control. Budget(s) will be the responsibility of the onshore and offshore team

leaders.

3.10 Resources

Sufficient suitably qualified and competent resources will be available on the installations

and in onshore support roles, to satisfactorily complete the maintenance activities and to

ensure the technical integrity of the installation(s) is maintained.

3.11 Audit

A maintenance Audit schedule and a maintenance Audit procedure will be developed. To

determine that the maintenance activities are being completed competently and correctly, to

the relevant maintenance standards and procedures.

Audits will be completed by both internal and independent external resources. Best practices

to be disseminated throughout all assets.

3.12 Cost

All costs associated with maintenance will be clearly transparent.

Maintenance costs will be tracked by two different integrated systems.

a. ORACLE The high level cost system used by finance department

b. MAXIMO The detail level cost control within the CMMS

3.13 Design

All engineering that is required to be completed for:

a. New Projects

b. Plant Modifications

c. Plant replacement

will comply with agreed operations and maintenance philosophy, including but not limited to

reliability, maintainability and standardisation.

3.13.1 Reliability Availability Maintainability (RAM) Model

“RAM” model generation for capital projects should be considered for development, to assist

in design decisions.



MAINTENANCE POLICY


12


3.14 Life Cycle Cost Model

A Life Cycle Cost Model will be used. All future equipment will be purchased after making

use of the model to assist in the selection process for plant and equipment. Similarly all

future project and modification scopes will use the model in the selection process for any

equipment purchased. Use of the model will be linked to the Procurement Process.

3.15 Equipment Repair or Replace Philosophy

When an item of equipment is removed from service for repair then the following formulas

will be used to determine whether the unit is to be repaired or replaced as a new item:

General Rule

a. IF (Cost of Repair 70% of Cost of new replacement) then REPAIR

b. IF (Cost of Repair ≥ 70% of Cost of new replacement) then REPLACE

However the following additional factors must be taken into consideration:

If “Lead Time” for the replacement is excessive compared to the repair time and the item is

critical to production then the item is to be REPAIRED.

This can be superseded by sanction of the Site Manager for Emergency Safety or Production

related items.

In all cases if production is directly effected then the method that has the shortest lead time

will be the method chosen regardless of cost.

3.16 Standardization

New or replacement equipment should be specified with standardisation on:

a. Type

b. Manufacturer

Providing this is supported by historical maintenance or operational evidence/experience.

Procurement strategy to be aligned with this philosophy.

3.17 Onshore Work Scopes

All scopes that can be completed onshore will be completed onshore. These are the

following:

a. Fabrication.

b. Equipment Repair/Overhaul



MAINTENANCE POLICY


13


This will reduce the cost of repairs and the numbers of personnel onboard the installations.

This can be superseded by sanction of the Site Manager for Emergency Safety or Production

related items, and on a cost benefit analysis basis.

3.18 Computerized Maintenance Management System

All maintenance to be managed by a CMMS. All costs will be tracked by the CMMS at the:

a. Tag Level.

b. Equipment Number Level.

Responsibility for the change management of the CMMS database will be with the

Maintenance Division as single point control. This will ensure that all changes follow a

change management process. The responsibility for the day to day quality of the data will be

with the Asset Line Management.

Access to the CMMS will be by secure “LOGIN” unique to assigned individual personnel.

3.18.1 Maintenance Types

Maintenance within the CMMS will be classified into three types:

a. Planned Maintenance (see Figure 1 below)

a1. Planned Maintenance Programs (Intrusive)

a2. Predictive Maintenance Programs (Non-intrusive)

a2.1 Condition Monitoring Programs

a2.2 Performance Testing

a3. Inspections Programs

a4. Shutdown Maintenance

b. Corrective Maintenance (see Figure 1 below)

c. Breakdown Maintenance (see Figure 1 below)

the condition of an item to determine the need for maintenance.

Conformity An affirmative indication or judgement that a product or service has met the

requirements of the relevant specifications, contract or regulation.

Deferment In terms of the maintenance programs this is the process by which relevant

management agrees that for operational reasons a maintenance program can be

deferred until next execution.

Example

Site Management can decide that a weekly maintenance program is not

completed that week for operational reasons. This means that the maintenance

program is not execute that week and not put into Backlog.

Deferment

Procedure

A system where the deferred production “loss” is collected into a database.

Example

A gas turbine generator shuts down due to fault. The Load Shedding system

cannot prevent the installation from loss of total electrical supply and production

is shut down. The deferred loss is that production that would have been

exported during the time the installations was shutdown, i.e. if in the case of

this example the generators were down for 1 hour then 1/24 of the daily

production would be the deferred loss. This and the reason for the loss would be

entered into the database.

a. Manpower Cost (Internal & External)

b. Service Contract

c. Material Cost

Fail-Safe A design property of an item which prevents its failure from resulting in critical

faults, e.g. an Emergency Shutdown Valve will close in the event of loss of the

supply medium keeping it open.

Failure The termination of the ability of an item to perform a required function. Failure

is an event resulting in fault which is a state.

Failure Mechanism The physical, chemical or other process which has led to failure.

Fault The state of an item characterized by the inability to perform a required

function. A fault is often the result of a failure.

MAINTENANCE POLICY


21



TERM DEFINITION

Planned

Maintenance

The maintenance organized and carried out with forethought, control and the use

of records to a predetermined plan.

Example

The core maintenance programs that are issued by the CMMS. Corrective

maintenance arises as the result of fault detection during a planned maintenance

program, i.e. a condition monitoring program highlights the need for a

corrective work order to be raised before a failure can occur.

Predictive/Proactiv

e Maintenance

This is the maintenance completed as the applicable type of condition

monitoring where data is collected from a functioning machine from which

decisions are made. The output of these decisions could be to raise a corrective

work order. This is a non-intrusive type of maintenance, i.e. maintenance that

can be completed with the equipment remaining in service.

Preventative

Maintenance

The maintenance carried out at predetermined intervals or according to

prescribed criteria and intended to reduce the probability of failure or the

degradation of the functioning of an item. This would be the Planned

Maintenance Programs that are issued by the CMMS. This is an intrusive type

of maintenance, i.e. maintenance that would necessitate the removal from

service of the equipment.

Breakdown

Maintenance

Maintenance of an item when it is in the breakdown condition.

See Example 2 of Corrective Maintenance

Unplanned

Maintenance

This is maintenance carried out to no pre-determined timescale, e.g. breakdown

maintenance.

Redundancy In an item, the existence of more than one means for performing a required

function.

Reliability The ability of an item to perform a required function under given conditions for

a given time interval.

Reliability Centred

Maintenance

(RCM)

A systematic approach for identifying effective and efficient preventive and

condition maintenance tasks for equipment and items in accordance with a

specific set of procedures and for establishing the intervals between

maintenance tasks.

Risk Based

Inspection

Inspection intervals allocated to equipment on a calculated risk based

methodology.

Schedule The specific time when a planned event will be completed.

Shutdown

Maintenance

Maintenance that is carried out only when the plant or system is out of service.

Specification The document that prescribes the requirements to which the product or service

has to conform.



MAINTENANCE POLICY


22



TERM DEFINITION

Standardisation The goal of reducing the different types of equipment or manufacturer on an

installation. Standardisation can be applied on an installation by installation

basis or as a company goal for all installations.

Standby

Redundancy

That redundancy wherein a part of the means for performing a required function

are inoperative until needed.

Corrective

Maintenance

The maintenance carried out after fault recognition and intended to put an item

into a state in which it can perform a required function. Corrective maintenance

is the vehicle by which the effectiveness of the planned maintenance is

monitored.

This definition requires some examples to fully explain what is classed as

Corrective Maintenance. For this three examples will be used to clarify the

definition.

Example 1 Inspection Action Report.

A report has been issued by the integrity department that informs the

maintenance department that a pipe spool has been identified by corrosion

monitoring/NDT inspection as having a defect that is nearing retrial thickness

and the spool is to be renewed. This is a corrective work order.

1. Spool and line are still in service so although no failure has arisen the

planned maintenance has identified the corrective action needed to return

the spool to original condition.

2. The replacement spool will be ordered and fitted in a planned manner.

Example 2 A Pump fails to give any output pressure

A production operator starts a pump but the pump will not give any output

pressure. This is not corrective work, it is a breakdown work order for the

following reasons:

1. A failure has occurred, the pump cannot perform its required function, i.e. it

cannot pump.

2. The fault will be the reason that the pump cannot pump. This will be

determined by investigation.

Example 3 Increase in Vibration Trend

A condition monitoring program has informed the maintenance department that
