1.0 INTRODUCTION

The management of Qatar Petroleum (QP) requires that the health and safety of allemployees and other persons who may be affected directly or indirectly by theiractivities, and the protection of its assets is ensured.

Dukhan Operations is committed to developing and enforcing safe workingpractices. This Permit to Work (PTW) System is a major element in complying withthese requirements, providing a mechanism for controlling workplace hazards, andprotecting employees, facilities and the public.

To ensure the PTW System is effective, DO NOT DEVIATE FROM IT. The systemis designed to ensure personal and environmental safety, and the integrity of plantand equipment.

This PTW Procedure is a formal written system that uses Work Permits to controlwork by means of potential hazard identification and risk assessment.

These work permits are also means of communication between plant management,plant supervisors, technicians who prepare and carry out the work.

THE ISSUE OF A WORK PERMIT DOES NOT, BY ITSELF, MAKE A JOB SAFE.SAFETY CAN ONLY BE ACHIEVED BY THOSE PREPARING THE WORK ANDTHOSE CARRYING OUT THE WORK.

The work permit is not simply permission to carry out a job. It is the cornerstone of asafe system of work that determines how that job can be carried out safely. A workpermit must not be regarded as a means of avoiding the need to eliminate hazardsor reduce risks, nor just an exercise in form filling. It does not remove individualresponsibility, as your signature means you are responsible.

IF YOU ARE UNSURE OF ANY INSTRUCTION ON A WORK PERMIT OR ARE INANY DOUBT REGARDING THE PTW PROCEDURE, STOP AND ASK YOURIMMEDIATE SUPERVISOR FOR GUIDANCE.

This procedure is applicable to the entire Dukhan Concession Area of QP.

Work Permits are not mandatory for aboveground civil infrastructure works insidethe Green Fields Areas of Dukhan Concession Area of QP.

1.1 Management of the PTW System

The Respective Asset Holder is responsible for ensuring that an effective PTWsystem is established and maintained. He shall also ensure that the system ismonitored, audited and reviewed as required. As a minimum the system shall bereviewed every three years and amended as necessary.



Page 2 of 47

The Asset Manager or his authorized representative has complete authority for theoperation and administration of the system, and shall appoint Permit Authorities asrequired.

Permit Authorities are the area supervisor for Operations - Dukhan Fields on allmatters related to the PTW system.

These supervisors are responsible for ensuring the workforce (with PTWresponsibility) under their authority, inclusive of contractors, are adequately trainedin the operation of the PTW system.

Administration of the PTW system shall be conducted in English and all personnelwho have responsibilities within the system shall be able to read and write in Englishand fully understand the requirements applicable to their role.

Training shall be provided via a QP approved and recognized training medium.

2.0 OBJECTIVES OF THE PTW SYSTEM

The Dukhan PTW system is designed to ensure:• a coordinated, communicated and controlled safe system of work• all work carried out is recorded• continuous improvement of the PTW system through audit and revision

3.0 WORK COVERED BY WORK PERMIT

Work shall not be carried out unless:• it has been approved by either Planned Maintenance Routine, Engineering

Department, Field Support Department or Plant Change Request (PCR).All other work not defined above must be approved and agreed by thePermit Authority.

• the work has been planned and agreed 24 hours in advance, or is of abreakdown nature or priority unplanned work requiring immediate action.

• all work permits have been properly authorized. All work in any arearequires a work permit, with the exception of emergency safety work that iseither ‘loss of life actual’ or ‘loss of life potential’.

In the event of a breakdown outside of normal working hours, priority unplannedwork or emergency safety work arising, the Permit Authority is authorized to verballyallow work to commence immediately. Work permits shall be prepared as soon aspractical to cover the work being carried out.

Note: If the above emergency procedure is used, it shall be recorded in the PlantPermit Logbook and signed and dated by the Permit Controller. Theensuing Incident Report shall also show how this work was carried out.

On being authorized, the Permit Controller shall review the work permit and anysupporting documentation and shall complete the appropriate sections. He shallarrange for equipment preparation, e.g. depressurizing, draining, flushing, purging,and any process, mechanical, safety, or electrical isolations required.

When he is satisfied that the worksite has been safely prepared (see Section 10 ofthis procedure) and lock-off keys for process / electrical isolations are secure in theLockout Box(es), the work permit details shall be recorded in the Work PermitRegister. Only when this is complete will the work permit and the relevantequipment be released to the Permit Applicant, after the Permit Controller hassigned.

8.5 Work Permit Issue

The Worksite Supervisor assigned by the Permit Applicant shall collect the preparedwork permit from the Permit Controller and sign the permit to acknowledge heunderstands it and accepts the associated worksite responsibilities.

The Worksite Supervisor shall then obtain the first endorsement from the PermitController for the work to proceed. He shall then proceed to the worksite tocommence the work.

No amendment to a work permit or certificate is permitted without the approval ofthe Permit Authority. Additional safety precautions may be added with the approvalof the Worksite Supervisor and the Permit Controller.Note: Overwriting or correction fluid on a work permit / certificate immediately

invalidates it and shall cause it to be cancelled, except in case of extension ofpermit (see Section 8.6 of this procedure).

If a work permit has all the endorsements complete but the isolations and work areto continue, a new work permit shall be raised. The new work permit shall then beapplied for and authorized using the normal procedure.

Each work permit endorsement from the Permit Controller is only valid for amaximum of one shift. The oncoming Permit Controller shall endorse workextension into the next shift. If the work permit endorsement boxes have all beencompleted, a new work permit shall be raised.

8.6 Extension of a Permit

If work has not been completed within the validity of a permit, a new permit shall beissued for the remaining work. The Serial Number of the new permit shall bestruck-off and the Serial Number of the old permit shall be written in its place. Allwork permits and certificates associated with the same work shall be cross-referenced by inserting the certificate number in the box provided on eachdocument. Additional certification raised during the validity of an issued permit shallalso be cross-referenced on all copies of the ‘live’ work permit. There will not beany limit to the number of new permits issued for completion of ongoing work.

normal operations, or could the work be deferred until a total or partialshutdown?

• has the workscope and potential hazards been discussed by the PermitApplicant, Safety Officer and Permit Controller?

• another hot work permit will NOT be issued for an area where a confinedspace entry certificate for work permits associated with this activity are inforce

• the performance of hot work is NOT permitted in the same area as workinvolving paint spraying or hand painting

• cold work that is likely to release hydrocarbons near to the site of hot workshall be suspended

• gas test is required; it shall be carried out immediately prior to thecommencement of work and, if the work party has left the worksite,immediately prior to resumption of work

• the Worksite Supervisor shall remain at the worksite during the performanceof the work as defined by the Permit Authority on the permit

• the number of hot work permits to be issued in any one area will bedetermined by the Permit Authority, based upon the availability of manpowerand equipment to control and make safe for the work to be carried out

a) Preparation and Performance of Hot Work

The Permit Controller and Permit Applicant shall make regular visits to theworksite during the work activity.

Total isolation from flammable or toxic gas / liquids shall be achieved in one ofthe following ways:

• physical disconnection• blinding using correctly rated blinds• spading using correctly rated spades• double block and bleed• any combination of the above as deemed necessary by the Permit

Authority / Permit Controller



Page 16 of 47

Note: It may be necessary to raise a Cold Work permit for this preparatory work.The Permit Authority shall assess this after discussion with the PermitController.

The Permit Controller shall ensure that the equipment is:

• depressurized• drained• vented• purged and flushed• or any of the above as required to allow hot work to commence

Caution: During the venting of hydrocarbons to atmosphere, all hotwork in the same area must be suspended.

9.5 Electrical Work Certificates and Associated Certificates

Engineering Standards – Electrical ES.E.50, Volume 6 shall be used to refer to theperformance of electrical work in Dukhan facilities.

a) Electrical Work Certificate

This is an electrical working document issued by an AEP, in conjunction with aprimary permit to work, for the purpose of specifying electrical equipment safe towork on (see Attachment F).

At the discretion of the AEP, an Electrical Work Certificate may be issued forwork on a low voltage system, e.g. work on the busbars of a 415V switchboard.The safety rules for work on high voltage systems shall apply to this work. Thiscertificate can be transferred between AEPs.

b) Electrical Section of the PRC

After discussion with the Permit Applicant, the requirement for electrical isolationshall be specified by the Permit Controller at permit application.

The PRC can be issued to a CEP for the isolation of low voltage equipment only,i.e. equipment not exceeding 1000V AC or 1500V DC. A PRC for high voltage,i.e. exceeding 1000V AC or 1500V DC, can only be issued to and performed byan AEP.

c) 33 KV Overhead Line Clearance Certificate

This is an electrical working document issued by an AEP, in conjunction with aprimary work permit, for the purpose of assessing clearance between temporaryconstruction equipment and 33 KV overhead lines (see Attachment K).

At the discretion of the AEP, this certificate may be issued to allow work to becarried out in the vicinity of such overhead lines.

9.6 Excavation Certificate

Excavation work shall be carried out under the control of an ‘Excavation Certificate’



Page 19 of 47

(see Attachment J), which will be supplemented by a primary work permit forexcavation work only authorized by the Permit Authority and the Permit Controller.

A drawing or sketch of the proposed excavation work and site shall be prepared bythe sponsoring department and submitted along with the certificate. This will enableany affected disciplines to identify hazards and specify precautions to be takenwhen signing for approval.

Considering the criticality of excavation or its proximity to live facilities, if the PermitController stipulates that the presence of the Permit Applicant / QP Representativeis required, then the relevant box will be ticked on the Excavation Certificate.

Excavation Certificates shall normally be presented for approval at least 24 hoursprior to the work commencing. The Permit Authority may authorize the immediateprocessing of a primary work permit and ‘Excavation Certificate’ for emergency workonly. Each Excavation Clearance Certificate shall be signed by the InstrumentationAuthority, Electrical Authority (Distribution), Electrical Authority (Operations),Telecommunication Authority, Civil Maintenance Authority, Mechanical MaintenanceAuthority, Water Authority (Potable and Fire) and Sewage Authority (Raw andTreated Sewage Effluent).

A matrix for identifying the respective authority for each area is included asAttachment Q.

Notes: I. The cancelled certificate shall be attached to the new certificate duringprocessing and retained by the Permit Controller until all work has beencompleted and the permit / certificate closed.

II. As soon as the “excavation” work is finished, the ExcavationCertificate shall be closed and a new permit shall be issued tocontinue the work at the excavated area.

The Worksite Supervisor shall examine the worksite each time the ‘ExcavationCertificate’ is endorsed to ensure it is safe to continue work. All excavationworksites shall be barricaded off, with warning notices written in English andArabic clearly visible. Flashing warning lights are mandatory during periods ofpoor visibility, e.g. during the hours of darkness, during foggy weather orsandstorms.

If an unexpected underground cable or pipeline is discovered during excavation, thework shall be stopped and the Permit Controller informed. He shall attend at theworksite and liaise with the Permit Authority to decide on the action to be taken.



Page 20 of 47

10.0 ISOLATION, LOCK OFF AND TAG

Isolation, lock off and tag is an integral part of the PTW System. If plant orequipment is specified as requiring isolation as a condition of the work permit, a‘Preparation / Reinstatement Certificate (PRC) shall be issued and becomes part ofthe work permit to which it is referenced.

Personal isolations are only permitted to be carried out by a CEP or AEP (forelectrical, instrument and telecommunications) as defined in ES.E.50. When suchisolations are used, this shall be identified by the Permit Authority on theappropriate section of the work permit as a condition of the work to be performed.Personal isolations can only be used for a period of one shift.

The method of isolation shall be detailed on the PRC and the isolation shall only becarried out by the nominated authorized person. If isolations require ‘locking off’,official QP padlocks, clearly stamped with an individual ID number, should be used.If padlocks cannot be installed, other approved immobilizing devices as specified bythe Permit Controller shall be used.

Isolation padlock keys and, where other forms of immobilizing devices are used, the‘tear off’ section of the isolation tags shall be locked in a Lockout Box (seeAttachment M). Each isolation point and any vent / drain point that has beenopened or closed shall have an isolation tag attached, clearly noted and referencedto the PRC.

10.1 Mechanical Isolation

The type of isolation used shall depend on the level of risk associated with the workto be performed. For further information, refer to IP-OPS-029.

10.2 Process / Mechanical Isolation Procedure

It is the responsibility of the Permit Controller to ensure that marked-up P&IDs andan approved spade list are issued to the Permit Applicant for use.

The physical application of isolations can be delegated by the Permit Controller toan appointed person (mechanical in the case of blind or blank installation). Allspades / blinds inserted, and ultimately removed again, shall be logged on a‘Spading / Blinding List (see Attachment L).

The effectiveness of isolations shall be tested and proved. If an isolation valve ispassing, it may be necessary to shut additional valves or take further plant orequipment out of service. The possibility of the presence of wax, hydrates, sludgeor scale under a valve seat should be considered, as subsequent pressure drop,melting or movement of the obstruction may render the isolation ineffective.

All isolation points shall be detailed on the PRC as follows:• all valves ‘locked closed’ and tagged• lock numbers shall be noted• vent and drain valves left in an abnormal position shall be tagged and noted



Page 21 of 47

• blind flanges, plugs, pipe joints or any other equipment removed or loosenedshall be tagged and noted

When the lockout box finally contains all the relevant isolation information, thenumber of the lockout box shall be recorded on the PRC.

The Permit Controller shall issue one lockout box key to the Worksite Supervisor,record the issue on the PRC, and obtain the relevant signature.

If an isolation is in force under a work permit and an additional work permit is raisedwhich requires exactly the same isolation, no additional isolation needs to becarried out. To ensure isolation control, an additional key is removed from thelockout box holding the appropriate isolation records and is handed over to thesecond Worksite Supervisor under signature.

The original and all copies of the PRC will be amended to reflect the issue of thesecond key, and both permits shall be cross-referenced to each other and the PRC.

A control system (issue and return) for the lockout box keys shall be developed bythe Permit Authority and any local rules approved by management. This may reflecteither a ‘2-key’ or ‘3-key’ system, dependent on the requirements of the userdepartment.

Example Matrix of Lockout Box 3-Key Distribution

Key Recipient Key NumberWorksite Supervisor (1) AWorksite Supervisor (2) B

Permit Controller C (Control)

The ‘C’ (Control) key from a lockout box shall not be issued to a WorksiteSupervisor. This key can be cascaded from work permit to work permit by beingplaced in an unused lockout box, providing additional Worksite Supervisors withlockout keys. This allows multiple work permits to be issued without jeopardisingthe integrity of the original isolation.

When the work associated with a work permit is completed, the Worksite Supervisorreturns the work permit, suitably signed off by the Permit Applicant, along with thelockout box key to the Permit Controller.

The Permit Controller and the Worksite Supervisor shall sign the ‘lockout box key’section on the PRC to record the return of the key.

If isolations need to remain in force, this shall be reflected on the work permit whenclosed, along with all associated work permits / certificates.

The original PRC shall be stamped with the letters ‘LTI’ (Long Term Isolation), andthe padlock keys, tags, and PRC shall be placed in the Long Term Isolation LockoutBox and recorded in the LTI Register.



Page 22 of 47

10.3 Electrical Isolation

The Permit Controller, in liaison with the Permit Applicant, shall specify therequirement for an electrical isolation.

Following discussion with the Permit Controller and the Permit Applicant, anappropriate AEP or CEP shall complete the ‘electrical isolation’ section of the PRC.

The isolation will be carried out using a padlock and key supplied by the PermitController. Once the isolation is effected, the AEP / CEP shall place the padlockkey(s) in the lockout box allocated by the Permit Controller and record thenumber(s) on the PRC.

The lockout box Key ‘A’ will then be issued to the Worksite Supervisor in charge ofthe work.

When the work requiring the electrical isolation is completed, the WorksiteSupervisor shall return his signed-off permit, with PRC attached, and lockout boxKey ‘A’ to the Permit Controller, who shall arrange for de-isolation by theAEP / CEP, provided it is safe to do so.

If the isolation needs to remain in force, this shall be reflected on the work permitwhen closed, along with all associated work permits / certificates.

The original PRC shall be stamped with the letters ‘LTI’ (Long Term Isolation), andthe padlock keys, tags, and PRC shall be placed in the Long Term Isolation LockoutBox and recorded in the LTI Register.

10.4 Long Term Isolation

If work is completed or suspended beyond the work permit’s period of validity, butthe worksite requires the continued protection of an electrical, mechanical, safety oremergency system isolation, the following shall apply:a) Sign off to close the original work permit.b) Stamp the original PRC with the letters ‘LTI’.c) Retain the original copy of the PRC, with the original work permit attached, in the

Long Term Isolation file, and give a copy to the Permit Applicant for his record.The details of the LTI shall be recorded by the Permit Controller.

d) The Permit Controller shall retain the lockout box control key and one other keyshall be retained by the Permit Authority.

When the work is to re-commence, the following shall apply:a) The Permit Applicant requiring release of the equipment / system shall raise a

work permit.b) The key held by the Permit Authority shall be returned to the Permit Controller,

who shall ensure that the original isolations are verified as being in place andeffective.



Page 23 of 47

c) The Permit Controller shall then transpose the original details from the LTI PRConto a new PRC, noting the name of the person who verified the isolations as the‘isolator’.

d) The Permit Controller shall draw 2 lines across the original LTI PRC, writecancelled and discard it. The new PRC shall be attached to the work permit.

The work can then be completed under normal PTW conditions. When the work iscomplete, the Permit Controller shall cancel all work permits, associated certificates,and remove the isolations.

11.0 SCAFFOLDING WORK UNDER PERMIT

The erection / dismantling and inspection of scaffolding shall be in accordance withIP-OPS-030.

All work to be carried out at a height above 2 metres shall be accomplished from acertified scaffold, secured ladder or purpose-built platform.

12.0 PERMIT AUDITING

Three audits per week shall be carried out on specific work permits as follows:• the Permit Authority shall audit 1 live work permit• the Permit Controller shall audit 1 completed work permit• a senior supervisor shall audit 1 completed work permit

The Permit Authority may, at his discretion, request other supervisors to carry outaudits.

LTIs shall be audited at least once per month.

A ‘Permit Compliance Checklist’ shall be completed for each audited work permit(see Attachment O). The Permit Authority shall endorse the audit findings and, ifdeficiencies are found, may put corrective actions in place immediately or makerecommendation for amendment to the PTW System (see Attachment P).

All completed audit reports shall be forwarded to the HSE Department forindependent review.

In addition to the formal audit program a PTW – STOP/OBSERVATIONCARDS ,also introduced in the Dukhan fields to collect the informationfrom the work site and to report the management about the PTWcompliance.
