Page 1 of 47 1.0 INTRODUCTION The management of Qatar Petroleum (QP) requires that the health and safety of all employees and other persons who may be affected directly or indirectly by their activities, and the protection of its assets is ensured. Dukhan Operations is committed to developing and enforcing safe working practices. This Permit to Work (PTW) System is a major element in complying with these requirements, providing a mechanism for controlling workplace hazards, and protecting employees, facilities and the public. To ensure the PTW System is effective, DO NOT DEVIATE FROM IT. The system is designed to ensure personal and environmental safety, and the integrity of plant and equipment. This PTW Procedure is a formal written system that uses Work Permits to control work 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 AND THOSE CARRYING OUT THE WORK. The work permit is not simply permission to carry out a job. It is the cornerstone of a safe system of work that determines how that job can be carried out safely. A work permit must not be regarded as a means of avoiding the need to eliminate hazards or reduce risks, nor just an exercise in form filling. It does not remove individual responsibility, as your signature means you are responsible. IF YOU ARE UNSURE OF ANY INSTRUCTION ON A WORK PERMIT OR ARE IN ANY DOUBT REGARDING THE PTW PROCEDURE, STOP AND ASK YOUR IMMEDIATE 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 inside the 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 PTW system is established and maintained. He shall also ensure that the system is monitored, audited and reviewed as required. As a minimum the system shall be reviewed every three years and amended as necessary. Owner OPERATIONS DUKHAN FIELDS
Page 2 of 47 The Asset Manager or his authorized representative has complete authority for the operation and administration of the system, and shall appoint Permit Authorities as required. Permit Authorities are the area supervisor for Operations Dukhan Fields on all matters related to the PTW system. These supervisors are responsible for ensuring the workforce (with PTW responsibility) under their authority, inclusive of contractors, are adequately trained in the operation of the PTW system. Administration of the PTW system shall be conducted in English and all personnel who have responsibilities within the system shall be able to read and write in English and 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: 3.0 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 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 the Permit Authority. the work has been planned and agreed 24 hours in advance, or is of a breakdown nature or priority unplanned work requiring immediate action. all work permits have been properly authorized. All work in any area requires a work permit, with the exception of emergency safety work that is either loss of life actual or loss of life potential. In the event of a breakdown outside of normal working hours, priority unplanned work or emergency safety work arising, the Permit Authority is authorized to verbally allow work to commence immediately. Work permits shall be prepared as soon as practical to cover the work being carried out. Note: If the above emergency procedure is used, it shall be recorded in the Plant Permit Logbook and signed and dated by the Permit Controller. The ensuing Incident Report shall also show how this work was carried out. Owner OPERATIONS DUKHAN FIELDS

He shall arrange 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 of this procedure) and lockoff keys for process / electrical isolations are secure in the Lockout Box(es), the work permit details shall be recorded in the Work Permit Register. Only when this is complete will the work permit and the relevant equipment be released to the Permit Applicant, after the Permit Controller has signed. 8.5 Work Permit Issue The Worksite Supervisor assigned by the Permit Applicant shall collect the prepared work permit from the Permit Controller and sign the permit to acknowledge he understands it and accepts the associated worksite responsibilities. The Worksite Supervisor shall then obtain the first endorsement from the Permit Controller for the work to proceed. He shall then proceed to the worksite to commence the work. No amendment to a work permit or certificate is permitted without the approval of the Permit Authority. Additional safety precautions may be added with the approval of 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 of permit (see Section 8.6 of this procedure). If a work permit has all the endorsements complete but the isolations and work are to continue, a new work permit shall be raised. The new work permit shall then be applied for and authorized using the normal procedure. Each work permit endorsement from the Permit Controller is only valid for a maximum of one shift. The oncoming Permit Controller shall endorse work extension into the next shift. If the work permit endorsement boxes have all been completed, 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 be issued for the remaining work. The Serial Number of the new permit shall be struckoff and the Serial Number of the old permit shall be written in its place. All work permits and certificates associated with the same work shall be crossreferenced by inserting the certificate number in the box provided on each document. Additional certification raised during the validity of an issued permit shall also be crossreferenced on all copies of the live work permit.

Page 14 of 47 9.0 PREPARATION OF THE WORKSITE It is the responsibility of the Permit Authority to ensure the safe preparation of the worksite. He may assign the application for process isolations to a nominated person, but he still retains overall responsibility. Electrical isolations shall be assigned via the AEP. When the Permit Authority decides it is necessary, the Permit Applicant shall prepare formal plant or equipment preparation procedures / method statement. This will be completed prior to the work commencing and reference should be made to any Simultaneous Operations procedures when necessary. The Permit Controller shall provide copies of markedup P&IDs, spade lists and/or isolation procedures to the Permit Applicant (mandatory for all vessel entry and process isolations). Based upon the detailed description of the work to be performed, hazards shall be assessed regarding the materials to be handled and the prevailing conditions. The possible impact of the work on the surrounding area shall be assessed and care taken not to issue a work permit that could impact on the safety conditions of other work permits in the area. The Permit Controller can introduce additional precautions if necessary based on his assessment. Based on the assessment of the hazards involved, the precautions to be taken to enable the work to proceed safely shall be indicated by the Permit Authority on the work permit. Based on the residual risks associated with the job, the permit/jsa to be escalated to higher management approval. Refer procedure QPRDKN25 on Job Safety Analysis for further details.

The contractor RPO shall ensure that all radiation safety precautions are in place as required. a final PA announcement shall be made to announce the commencement of radiography Electrical Work Certificates and Associated Certificates Engineering Standards Electrical ES.E.50, Volume 6 shall be used to refer to the performance of electrical work in Dukhan facilities. a) Electrical Work Certificate This is an electrical working document issued by an AEP, in conjunction with a primary permit to work, for the purpose of specifying electrical equipment safe to work on (see Attachment F). At the discretion of the AEP, an Electrical Work Certificate may be issued for work 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. This certificate can be transferred between AEPs. b) Electrical Section of the PRC After discussion with the Permit Applicant, the requirement for electrical isolation shall 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 by an AEP. c) 33 KV Overhead Line Clearance Certificate This is an electrical working document issued by an AEP, in conjunction with a primary work permit, for the purpose of assessing clearance between temporary construction equipment and 33 KV overhead lines (see Attachment K). At the discretion of the AEP, this certificate may be issued to allow work to be carried 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 Owner OPERATIONS DUKHAN FIELDS
Page 19 of 47 (see Attachment J), which will be supplemented by a primary work permit for excavation 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 by the sponsoring department and submitted along with the certificate. This will enable any affected disciplines to identify hazards and specify precautions to be taken when signing for approval. Considering the criticality of excavation or its proximity to live facilities, if the Permit Controller stipulates that the presence of the Permit Applicant / QP Representative is required, then the relevant box will be ticked on the Excavation Certificate. Excavation Certificates shall normally be presented for approval at least 24 hours prior to the work commencing. The Permit Authority may authorize the immediate processing of a primary work permit and Excavation Certificate for emergency work only. Each Excavation Clearance Certificate shall be signed by the Instrumentation Authority, Electrical Authority (Distribution), Electrical Authority (Operations), Telecommunication Authority, Civil Maintenance Authority, Mechanical Maintenance Authority, Water Authority (Potable and Fire) and Sewage Authority (Raw and Treated Sewage Effluent). A matrix for identifying the respective authority for each area is included as Attachment Q. Notes: I. The cancelled certificate shall be attached to the new certificate during processing and retained by the Permit Controller until all work has been completed and the permit / certificate closed. II. As soon as the excavation work is finished, the Excavation Certificate shall be closed and a new permit shall be issued to continue the work at the excavated area. The Worksite Supervisor shall examine the worksite each time the Excavation Certificate is endorsed to ensure it is safe to continue work. All excavation worksites shall be barricaded off, with warning notices written in English and Arabic clearly visible. Flashing warning lights are mandatory during periods of poor visibility, e.g. during the hours of darkness, during foggy weather or sandstorms. If an unexpected underground cable or pipeline is discovered during excavation, the work shall be stopped and the Permit Controller informed. He shall attend at the worksite and liaise with the Permit Authority to decide on the action to be taken. Owner OPERATIONS DUKHAN FIELDS
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 or equipment is specified as requiring isolation as a condition of the work permit, a Preparation / Reinstatement Certificate (PRC) shall be issued and becomes part of the work permit to which it is referenced. Personal isolations are only permitted to be carried out by a CEP or AEP (for electrical, instrument and telecommunications) as defined in ES.E.50. When such isolations are used, this shall be identified by the Permit Authority on the appropriate 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 be carried 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 by the 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 (see Attachment M). Each isolation point and any vent / drain point that has been opened or closed shall have an isolation tag attached, clearly noted and referenced to the PRC. 10.1 Mechanical Isolation The type of isolation used shall depend on the level of risk associated with the work to be performed. For further information, refer to IPOPS029. 10.2 Process / Mechanical Isolation Procedure It is the responsibility of the Permit Controller to ensure that markedup P&IDs and an approved spade list are issued to the Permit Applicant for use. The physical application of isolations can be delegated by the Permit Controller to an appointed person (mechanical in the case of blind or blank installation). All spades / 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 is passing, it may be necessary to shut additional valves or take further plant or equipment out of service. The possibility of the presence of wax, hydrates, sludge or 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 Owner OPERATIONS DUKHAN FIELDS
Page 21 of 47 blind flanges, plugs, pipe joints or any other equipment removed or loosened shall be tagged and noted When the lockout box finally contains all the relevant isolation information, the number 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 raised which requires exactly the same isolation, no additional isolation needs to be carried out. To ensure isolation control, an additional key is removed from the lockout box holding the appropriate isolation records and is handed over to the second Worksite Supervisor under signature. The original and all copies of the PRC will be amended to reflect the issue of the second key, and both permits shall be crossreferenced to each other and the PRC. A control system (issue and return) for the lockout box keys shall be developed by the Permit Authority and any local rules approved by management. This may reflect either a 2key or 3key system, dependent on the requirements of the user department. Example Matrix of Lockout Box 3Key Distribution Key Recipient Worksite Supervisor (1) Worksite Supervisor (2) Permit Controller Key Number A B C (Control) The C (Control) key from a lockout box shall not be issued to a Worksite Supervisor. This key can be cascaded from work permit to work permit by being placed in an unused lockout box, providing additional Worksite Supervisors with lockout keys. This allows multiple work permits to be issued without jeopardising the integrity of the original isolation. When the work associated with a work permit is completed, the Worksite Supervisor returns the work permit, suitably signed off by the Permit Applicant, along with the lockout 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 when closed, along with all associated work permits / certificates. The original PRC shall be stamped with the letters LTI (Long Term Isolation), and the padlock keys, tags, and PRC shall be placed in the Long Term Isolation Lockout Box and recorded in the LTI Register. Owner OPERATIONS DUKHAN FIELDS
Page 22 of 47 10.3 Electrical Isolation The Permit Controller, in liaison with the Permit Applicant, shall specify the requirement for an electrical isolation. Following discussion with the Permit Controller and the Permit Applicant, an appropriate 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 Permit Controller. Once the isolation is effected, the AEP / CEP shall place the padlock key(s) in the lockout box allocated by the Permit Controller and record the number(s) on the PRC. The lockout box Key A will then be issued to the Worksite Supervisor in charge of the work. When the work requiring the electrical isolation is completed, the Worksite Supervisor shall return his signedoff permit, with PRC attached, and lockout box Key A to the Permit Controller, who shall arrange for deisolation by the AEP / CEP, provided it is safe to do so. If the isolation needs to remain in force, this shall be reflected on the work permit when closed, along with all associated work permits / certificates. The original PRC shall be stamped with the letters LTI (Long Term Isolation), and the padlock keys, tags, and PRC shall be placed in the Long Term Isolation Lockout Box 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, but the worksite requires the continued protection of an electrical, mechanical, safety or emergency 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 key shall be retained by the Permit Authority. When the work is to recommence, 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 and effective. Owner OPERATIONS DUKHAN FIELDS
Page 23 of 47 c) The Permit Controller shall then transpose the original details from the LTI PRC onto 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, write cancelled 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 is complete, 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 with IPOPS030. All work to be carried out at a height above 2 metres shall be accomplished from a certified scaffold, secured ladder or purposebuilt 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 out audits. 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, if deficiencies are found, may put corrective actions in place immediately or make recommendation for amendment to the PTW System (see Attachment P). All completed audit reports shall be forwarded to the HSE Department for independent review. In addition to the formal audit program a PTW STOP/OBSERVATION CARDS,also introduced in the Dukhan fields to collect the information from the work site and to report the management about the PTW compliance. This to be utilized for stopping any unsafe act if observed at worksite. Refer Attachment R for the form. 13.0 RESPONSIBLE PERSONS PTW position holders are required to have completed the appropriate training and be certified accordingly. Certification shall be the responsibility of the respective Department Head and, where appropriate, the Permit Authority. Owner OPERATIONS DUKHAN FIELDS
