Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 726

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

bull Connection of temporary equipment or links between systems

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 826

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1226

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 726

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

bull Connection of temporary equipment or links between systems

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 826

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1226

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

Management of Engineering Change Procedure

1 PrefaceThis document should be read in conjunction with the Management of Change Framework [HOLD]This framework defines the different types of change management to adequately manage businessrisk

Change is classified into three (3) categories

a Engineering Change

b Procedural Change andc Organizational Change

This procedure covers Engineering Change pertaining to EQ Petroleum Production Malaysia Ltdand EQ Petroleum Development Malaysia Sdn Bhd (herein referred as lsquoEnQuestrsquo) operations

Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

bull Connection of temporary equipment or links between systems

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 726

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

bull Connection of temporary equipment or links between systems

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1226

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

2 Introduction

Change is inevitable and necessary and shall be properly managed and monitored Anyuncontrolled change can introduce new risks invalidate previous works and may lead toundesirable hazardous results

21 Objective

The objective of this procedure is to provide EnQuest operational assets with defined minimumrequirements for the Management of Engineering Change process This ensures engineeringtechnical andor operational process changes to surface facilities are evaluated and managedconsistently in terms of any new risks or benefits introduced These risks or benefits include safetyenvironmental technical and commercial criteria

This procedure is not intended to address organisational and sub-surface changes that areadequately managed under appropriate specific procedures

22 Scope

The scope of this Engineering Change procedure covers the following key steps

1) Identification of an Engineering Change

2) Engineering Change Proposal

3) Engineering Change Assessment

4) Technical and Management Review

5) Engineering Change Close Out

Modifications that are adequately covered by existing control procedures or not affecting theintegrity of the surface operational facilities are excluded from the scope of this document

Typically these would be as follows

bull ldquoLike for Likerdquo maintenance replacements ndash as these are not considered engineeringchanges

Management of Engineering Change Procedure

bull Drilling and sub-surface changes to wells or well intervention workover programs are

addressed under Well Integrity design or activity change controls

bull Documentation changes unless as a consequence of engineering change

bull Administrative or business software systems not covered within Safety Critical performancestandards

bull Organisational and Business Environment changes which will be covered by other change

management procedures

23 National Legislation

At all times our Management of Engineering Change process must comply with any appropriateMalaysian National Regulatory legislation and permitting requirements or PETRONASrequirements

3 Management of Engineering Change Procedure

Refer to Management of Engineering Change Process Flowchart in Appendix 2

31 Identification of an Engineering Change

In order to aid the definition of what might be considered an engineering change the followingexamples are listed for guidance

bull Facilities addition modification or removal

bull Installation of new equipment such as gas compressor pump and metering package

bull Change to alternative type of equipment

bull Changes to pipe-work routing or valveconnection configuration

bull Modifications to any tanks or pressure vessels

bull Removal of or establish a long term isolation to redundant equipment

bull Connection of temporary equipment or links between systems

Management of Engineering Change Procedure

bull Process Data transfer communication system changes

bull Hardwired relay based or solid-state logic

bull Change in material specification such as carbon steel to stainless steel

bull Changes to injected chemical types

bull Equipment replacement with non-identical parts

bull Change to Operating procedures in deviating from initial design intent

bull Changes to existing locked open (LO) locked closed (LC) valve status

bull Long term change to spectacle spade blind status

bull Impact on electrical zone classification areas

bull Change to active and passive Fire protection systems

bull Changes impacting safe access to designed escape routes

bull Any changes having an impact on Safety Case

bull Any of the above on a temporary basis not covered by a formal procedure

A basic assessment of whether a change requires compliance to the Management of EngineeringChange process is summarised in the ldquoMoEC Requirement Checklistrdquo attached in Appendix 1

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

httpslidepdfcomreaderfullenq-sel-eg-0000-prc-0001-revb-signature 1026

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

32 Engineering Change Proposal

In accordance with Management of Engineering Change flowcharts Appendix 2 the engineeringchange is initiated by completing Part 1 Engineering Change Proposal as shown in figure below

The Initiator has to describe the opportunity or issue the proposed change solution and the reasonwhy a change is necessary

If the change is intended to be temporary the Initiator shall state the expected duration Themaximum duration for a temporary change is three (3) months after which an extension is required

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

Management of Engineering Change Procedure

Upon completion the form shall be submitted to the Line Manager who will review the scope and

justification of the proposal If the Line Manager supports the proposal heshe summits theproposal to the MOEC Coordinator for registration

If the Line Manager rejects the proposal heshe shall advise the Initiator the basis of not acceptingthe proposal

When the MoEC Coordinator receives the proposal he will assign a unique MOEC Number andsend an acknowledgement email to the Line Manager and Originator to confirm registration

33 Engineering Change Assessment

If the MoEC is raised from offshore the Engineering Manager will assign an Onshore DisciplineEngineer (ODE) to support with the change assessment Otherwise the Initiator shall complete theassessment The assessment reviews the risks and benefits of the proposed change and providesan overall implementation cost estimate

The Initiator ODE in consultation with the HSE Department determines whether the Changerequires a complete risk assessment based on the guideline identified in Section 3 of the Hazardand Effects Management Process [1] If the change is simple then 21 (a) and (b) could be usedThe risk assessment ranking will be conducted using the EnQuest Risk Assessment Matrix andDecision Making Framework (Appendix 4) A summary of the risk ranking outcome will be providedin the 21

The cost estimate has to consider the total installed cost of the change which includes designprocurement fabrication implementation commissioning 3rd party supports and contingency

After the assessments the Initiator or ODE (if raised from Offshore) shall complete Part 2 of theMOEC form depicted in Figure 3 2 and attach all support documents before forwarding to theMoEC Coordinator

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

34 Technical and Management Review of Proposal

There are two (2) levels of reviews The initial review is by relevant functional manager andfollowed by management consensus review through a forum called Engineering Change Forum(ECF) that is chaired by the Asset Manager or hisher delegate

341 Initial Review

The initial functional review in general consists of the Offshore OIM HSE Manager Onshore OIMand Engineering Manager The MoEC Coordinator will also decide whether additional disciplinaryspecialist is required for the type of change such as multi-disciplinary change

Their input and recommendation regarding the change will be recorded in ldquoPart 3 Technical andManagement Reviewrdquo of the MoEC Form refer to Appendix 3

These initial reviewers where appropriate should discuss the change proposal with appropriatemembers within their team or engaging external specialist

The initial reviewers will have 5 working days to review comment and revert their comments to theMoEC Coordinator

342 Engineering Change Forum

On a monthly basis or more frequent if deemed necessary the MoEC Coordinator will organiseand facilitate the Engineering Change Forum (ECF) that is chaired by the Asset Manager

The Initiator or ODE will present their MoEC Proposal

The purpose of the meeting is to establish a consensus that the proposed change has a technicalandor business case to progress into Engineering Development and Execution

ECF would either ldquoacceptrdquo ldquorejectrdquo ldquoholdrdquo or ask for more definition on the Change ProposalldquoFurther Work Requiredrdquo If approved for progression the following shall be executed

a) The MoEC shall be marked ldquoApprovedrdquo and the Asset Manager shall sign the Proposal withinclusion of any recommendations

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

Management of Engineering Change Procedure

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

Management of Engineering Change Procedure

The ECF key discussion and decision will be formally recorded and distributed by the MoEC

Coordinator

35 Management of Change Close-Out

This phase commences when the Engineering Change is mechanically completed commissionedand handed over to Operations The Engineering Change Owner would prepare the Close-outPackage and completes ldquoPart 4 Close Out Verification and Approvalrdquo of the MoEC Form

A Checklist is provided within the Part 5 of the form defining the minimum requirements required toadequately close the MoEC

The final close-out is only accepted as complete when all close-out activities have been completedand Part 5 of the form is approved and signed off

Finally the form shall be forward to the MoEC Coordinator for update and filing

4 Engineering Change Management

41 Duration of change

Duration of change can be either permanent or temporary

A Permanent Change is a change that is intended to remain in place indefinitely Risk assessmenthas to be conducted to assess the change proposal and to ensure that the risk associated with thechange is at ALARP

A Temporary Change is a change intended to remain in place for a specified period only At theend of that period the change will be normalized and or permanent change implemented For alltemporary MoEC (eg Equipment hardware change operating parameter etc) the maximumduration of the change is three (3) months

If extension to a temporary change is required a further three (3) monthly extension is permitted toan absolute extension duration of 18 months (including the first 3 months) The extension shall beapplied and approved by the ECF before the expiry In addition the control and recovery barriers tocater for temporary change shall be regularly monitored throughout the change duration to ensure it

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

a) Significant safety risk to personnel

b) Major environmental impact

c) Potential serious equipment or facility damage

d) Managing an Emergency Incident

e) Major production impact

The Offshore OIM can take the sole authority to review and directly approve an Emergency Urgentchange for implementation and start-up

However the Offshore OIM must fully understand the technical and operational basis of thechange Heshe may seek the advice from the Engineering Manager andor specialist disciplineengineers This discussion may be through telephone communication but shall be reconfirmed inwriting using email

The Offshore OIM shall raise the Engineering Change proposal and compile it with all supportingdocuments The MoEC proposal shall be transmitted to and registered by the MoEC Coordinatorwithin 48 hours after the change is implemented In order to ensure the change is adequatelyreviewed the change shall go through the normal MoEC process at an earliest date with a highpriority An ad-hoc ECF may be convened

5 MoEC Recording and Reporting

51 MoEC Record Keeping

Adequate documentation of all Change Proposal is important

The MoEC Coordinator is responsible for maintenance of the MoEC Register and record keeping

system The MoEC Coordinator shall issue a unique MoEC number for each change maintain anoverall status report until completion or cancellation of all change in the MoEC process and ensurethat the MoEC Form and associated documents are legible and auditable

Each asset such as PM8E and Tanjong Baram will maintain its own register

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related

Management of Engineering Change Procedure

APPENDIX 1 Engineering Change Assessment Checklist

If the answer to all seven questions is ldquoNOrdquo the work scope is not considered as an engineering

change Hence this MoEC procedure is not necessary

No Questions Comments

1 Does the work revise the PampID Electrical System drawingsSafety Case or Safety System logic

Any work that requires a revision to a current MasterDocument is a change

Note A PampID or Master Document correction to properly document an existingapproved as-built equipment installation is not a change

2 Does the work use parts that are not replacement-in-kind

Any replacement that does not satisfy all designspecifications or is not identical to engineering drawings is achange

3 Will this action lead to operating outside established limitsRates pressures temperatures and levels that are outsideestablished Safe Operating Limits (SOLs) constitute achange

Established SOLs are typically found in process descriptionsand start-up and operating manuals If SOLs are not knownthen the assumed answer is ldquoYESrdquo

4 Will new chemicals or wastes be involved Consider alladditives products and waste streams New materials orthose that vary in quality or composition from existingmaterial safety data sheet (MSDS) documentation constitutea change

5 Does the work involve addition or deletion of equipmentEquipment includes but is not limited to pressure vesselstanks piping machinery instrumentation electricalequipment supporting structures and safety system

6 Does the action involve new or revised engineering related
