Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 1 Introduction An HSE Case provides a documented demonstration that risk reduction philosophies and measures have been developed and implemented at each phase of the Opportunity Realisation Process (ORP) to ensure that the risks are tolerable and as low as reasonably practicable (ALARP) through the systematic application of the Hazards and Effects Management Process (HEMP) as set out in the PDO HSE Management System (HSEMS). This document should be read in conjunction with the guideline Applying Process Safety in Projects GU-648 [4]. 1.1 Purpose This purpose of this specification is to establish minimum requirements for the content of HSE Cases and it shall be used for the development of HSE Input to Concept Select Reports, Design HSE Cases and Operations HSE Cases. This specification SHALL [PS] be used for demonstration of the following requirements of the Process Safety Manual in the Shell HSSE & SP Control Framework [Ref. 7]: Identify and document Hazards with RAM red and yellow 5A and 5B Process Safety Risks for existing and new Assets (Requirement 1). Develop a Statement of Fitness for the Assets (Requirement 7) Review the Process Safety Risks to the Asset at least annually, in line with 8 Management Review (of the HSSE & SP Management System) (Requirement 20). This specification contains information on the contents of each type of HSE Case and gives guidance and examples of information to be contained in specific sections. 1.2 General Definitions The capitalised term SHALL [PS] indicates a process safety requirement. The lower case word shall indicates a requirement. The word should indicates a recommendation. 1.3 Review and Improvement (SP 2062) Responsibility for the upkeep of this Specification shall be with the CFDH Technical Safety Engineering (Owner of this Specification). Changes to this document shall only be authorised and approved by the Owner. Any user of this document who encounters a mistake or confusing entry is requested to immediately notify the Document Custodian using the form provided in CP 122 Health, Safety and Environment Management System [Ref. 1]. This document shall be reviewed as necessary by the Owner, but not less than every two years. 1.4 Deviation from Standard Deviation to this Specification shall follow the requirements of PR-1247 “Project Change Control & Standards Variance Procedure”, Version 1 31/8/1999.

Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC 2 WHEN ARE HSE CASES REQUIRED? HSE Cases are mandatory for all PDO operated (owned, leased or contracted) projects/operations containing hazards rated severity five or high risk on the PDO risk assessment matrix (RAM) as per Figure 2-1 [Ref. 1]. Hazards to that fall into this category are referred to as Major Accident Hazards (MAH), and are typically identified during the HAZID conducted at the start of concept phase of a project. However, for smaller, less complex projects or modifications to an existing asset where an Operations HSE Case already exists, it may be suitable to undertake a design review in place of a Design HSE Case and then update the existing Operations HSE Case. For projects that fall into Category C as per Figure 2-2 overleaf, both qualitative (bow-tie analysis) and quantitative analysis (QRA) are required to determine the level of risk and to demonstrate that risks are reduced to tolerable and ALARP, thus a Design and Operations HSE Case must be compiled. Guidance and confirmation shall be sought from MSE/4 on an individual project basis. Consequences 1 Slight injury or health effect Slight damage 2 Minor injury or health effect Minor damage 3 Major injury or health effect Moderate damage 4 PTD or up to 3 fatalities Major damage 5 More than 3 fatalities massive damage Reputation No injury or 0 health effect No damage Environment Asset People Severity A No effect No impact Slight effect Slight impact Increasing likelihood B C D E Never Heard of in Has Has Has heard of in the Industry happened happened happened the Industry in PDO or at the more than more than Asset or 1>yr at the 1>yr in the more than Asset Industry 1>yr in PDO Minor effect Minor impact Moderate effect Moderate impact Major effect major impact massive effect Massive impact Figure 2-1: PDO Risk Assessment Matrix Figure 2-2 shows the industry guidelines for a framework for risk related decision support by Oil and Gas UK in 1997 (formerly the UK Offshore Operations Association, UKOOA). Once a new project has been assessed against the risk assessment matrix in Figure 2-1 and found to contain level 5 or high risk hazards, it shall be categorised as per the chart in Figure 2-2.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Figure 2-2: Framework for risk related decision support in PDO To use the Framework, first relate the decision being considered to the decision context characteristics on the right hand side of the Framework. Establish a horizontal line across the Framework at the point that best fits the nature of the decision. The segments of this horizontal line define the relative weight that should be given to the different decision making approaches in the ALARP determination. The descriptors on the lefthand side of the diagram describe the type and extent of consultation that is needed for the selected decision context and type. Type B and C decisions shall be taken at higher levels within an organisation than Type A decisions. Type A decisions are those involving well-understood hazards and proven solutions. The lessons learned from past years have been incorporated into authoritative Good Practice. Reference to the relevant Good Practice, supported by expert judgment, is sufficient to define the barriers needed to reduce the risks to both tolerable and ALARP. Type B decisions are those involving less well-understood hazards. Good Practice has to be supplemented by more detailed analytical methods such as quantified risk assessment (QRA) particularly to address the uncertainties of novel aspects of design. However, riskbased analysis cannot be the only approach, as illustrated by the fact that it forms no more than 40% of a horizontal line through the Type B band. Type C decisions are those involving hazards that may create societal concerns. The more technological factors in the ALARP determination need to be “conditioned”, or viewed in the context of how the situation will be seen by stakeholders. The A, B, C groupings are not intended to split the framework into three discrete sections, but should be used to indicate a continuum of decision context types from a strongly Type A (technology based) at one extreme to a strongly Type C (judgment based) at the other extreme. A range of decision-making approaches will contribute, especially to Type B and C decisions. The background to the Framework is described in [4].

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 3 WHAT TYPES OF HSE CASES ARE THERE? PDO activities and operated facilities fall into different categories and the different types of HSE Cases used to cover these are listed below: o Asset/facility: hydrocarbon gathering/production facilities organised into delivery teams or hydrocarbon transporting infrastructure and storage facilities. The majority of PDO HSE Cases fall into this category and the content shall meet the requirements of this HSE Case Specification o Contractor drilling rigs and hoists; the content shall meet the requirements of International Association of Drilling Contractors (IADC) [Ref. 4] and this HSE Case Specification o Air Operations; the content shall meet the requirements of EP 2005-0263 Air Transportation Standard and this HSE Case Specification o Land Transport; the content shall meet the requirements of EP 2005-0261 Road Transportation Standard and this HSE Case Specification Air transport operations, road transport operations and marine operations with severity 5 or high level hazards (as defined by the RAM in Figure 2-1) that are PDO operated (owned, leased or contracted) shall have an Operations HSE Case. The nature of Transport and Drilling Rig HSE Cases is that they are developed to describe the hazards and set out controls associated with the respective operation or activity. These cases are reviewed and updated as they develop, but rarely is there a requirement to develop a new HSE Case for these activities. Asset/Facility HSE Cases differ in that new design projects or production stations may require that a new HSE Case is developed in accordance with this specification. Asset/Facility HSE Cases are further separated into the following types of HSE Cases: o Concept Select Report: This demonstrates that there has been a systematic application of HEMP during the Identify, Assess and Select phases, that the HSE risks associated with each development option have been identified and assessed, the lowest risk option has been chosen or that the cost/effort required to adopt the lowest risk concept is grossly disproportionate to the benefit. o Design HSE Case: This demonstrates that there has been a further systematic application of HEMP during the Define and Execute phases, demonstrates that the severity 5 or high level hazards identified are both tolerable and ALARP and that all safety critical elements (with associated performance standards) have been identified and meet the performance standards. o Operations HSE Case: This describes management of the severity 5 or high level hazards to ensure that they are tolerable and ALARP, bow-tie diagrams showing the hazards and the barriers to the hazards, a list of HSE critical tasks, references to operational management systems and a statement of fitness. This acts as confirmation that the HSE Case Owner (Director) is satisfied that the arrangements are in place for the facility to operate safely. 3.1 Asset/Facility HSE Cases at different ORP phases The opportunity realisation process (ORP) is split into 5 phases punctuated by Decision Gates (Dg1-5) and Value Assurance Reviews (VAR1-5). Once the need for an HSE Case has been identified, the type of HSE Case and when it should be compiled needs to be identified as per Figure 3-1. The Identify & Assess; Select; Define; Execute and Operate phases are discussed in the following sections. Page 11 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Figure 3-1: 5 stages and applicable HSE Cases 3.1.1 Identify and Assess This phase initiates opportunities and demonstrates the feasibility of those opportunities. Ideas are generated and aligned with business principles and strategies and potential values established so a decision to fund and staff further development of these ideas can be made. This phase also asks the question as to whether the project has looked sufficiently at the risks, different development options, realisations and all possible outcomes. Is there at least one solution that would work in most, perhaps all, of the realisations? The project must understand what it is going to be taking into the Select phase. HSE input at this stage is at a high level and includes a preliminary HAZID, HSE-SD Plan and input to the Risk Register. 3.1.2 Select This stage must select the best concept solution for delivering value from the opportunity and make it clear why one choice was the preferred option. HSE input into the select phase has potentially the greatest impact. The option selected to take forward into the define phase must be ALARP. An ALARP demonstration must be provided in the CSR (see section 14). 3.1.3 Define The selected concept must be defined technically (scope, cost, schedule) or commercially (JVA, JOA, country entry) for final investment decision (FID). Note that the timing of a technical FID may not coincide with a commercial FID. HSE activities and deliverable at the define stage include a Design HSE Case and other HEMP Studies. 3.1.4 Execute The project is to be delivered as a facility consistent with the forecast scope, cost, schedule and proven performance and has to be accepted by the Owner of operations (usually the Relevant Director) for use. Page 12 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC During the execute phase the Design HSE Case is refined. The Operations HSE Case is developed prior to handover to operations. Further HEMP studies are carried out to support the ALARP Demonstration. 3.1.5 Operate The project is operating as per expected and is maximising returns to Shareholders and protecting the License to Operate. The Owner of operations (usually the relevant Director) has accepted responsibility for continued safe operations. The Operations HSE Case will contain the ALARP demonstrations for the Operate phase. This is built and maintained throughout the operate phase, (see section 16). 3.2 Roles and Responsibilities for the HSE Case Delivery Team Leaders (DTL): DTLs are responsible for ensuring that the HSE Cases are developed and maintained for their assets and meet the requirements of this specification. Project Managers: Project Managers are responsible for ensuring that the Concept Select Report and Design HSE Cases are developed and meet the requirements of this specification. Contract Holders: For Air Operations, Road Transport and Drilling & Hoist Rigs, it is the Contract Holders that are responsible for ensuring that their Contractors develop and maintain HSE Cases that meet the requirements of this specification. 3.2.1 Sign Off Dates Sign off dates for the CSR/HSE Cases shall be as follows: o o o o The Concept Select Report Case shall be signed off prior to VAR3. The Design HSE Case shall be signed off prior to VAR4. The Design HSE Case during detailed design phase shall be signed off when completed and prior to the PSUA. The Operations HSE Case shall be signed off prior to start up. 3.3 Roles and Responsibilities within the HSE Case There are three main roles for developing, implementing and maintaining an HSE Case; the HSE Case Owner, HSE Case Custodian and the HSE Case Administrator. These roles for each type of HSE Case are shown in Table 3-1 and cover new projects and modifications to existing facilities.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 3.4 Workforce Involvement The HSE Case shall demonstrate that the workforce have been part of the development and review of the HSE Case. Workforce in this context is the front line operations and maintenance staff that are directly involved in the day-to-day running of the facilities. The purpose of this requirement is to ensure that front line operations and maintenance staff: have knowledge of the Major Accident Hazards that have been identified for the facility where they work are aware of the controls and barriers in place to manage these MAHs (SCEs, performance Standards, HSE Critical Tasks, MOPOs) have knowledge of how these controls are managed (MIE, FSR, assurance reviews) For Design HSE Cases, workforce involvement can be demonstrated by ensuring that relevant staff representatives have been involved in the design. This may be done by ensuring they participate directly in the design activities (HAZIDs, HAZOPs, HEMP studies) and by participating in project assurance reviews such as Design Reviews, peer reviews and project Audits. Operations HSE Cases shall be communicated to the operations and maintenance teams on site. The focus shall be on what the case means to them and what impact is it likely to have. In addition, representatives from current operational, engineering, and maintenance teams and workforce representatives (where applicable) shall be included in the regular reviews as described in Section 13. This engagement may be demonstrated by ensuring that the HSE case is reviewed regularly by operations and maintenance staff, which can be achieved through job descriptions and staff performance contracts dedicated communications initiatives staff onboarding committees or working groups (e.g. AIPSALT). For both types of HSE Cases, the details of how workforce involvement has been achieved shall be described in the HSE Case or in the documentation of the periodic review of the HSE Case. 3.5 Deliverables Design and Operations HSE Cases are classified as Essential Records according to CP102 “Documents & Records Management” and shall be maintained on Livelink by the HSE Case Administrator. Design and Operations HSE Cases are mandatory deliverables for new projects and existing assets, as described by the Discipline Control and Assurance Framework (DCAF) section in SP-2061 Technical Authority System [Ref. 7]. 3.6 Performance Monitoring Routine performance monitoring of HSE Cases shall include: o o Page 16 Assurance of Design HSE Cases at VARs Review of Operations HSE Cases during Pre-Start up Audits SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®.

Petroleum Development Oman LLC o o Revision: 1.0 Effective: Mar-11 AI-PSM Assurance of Operations HSE Cases Monitoring of Operations HSE Case KPIs 3.6.1 Review and Improvement (HSE Cases) Once the Concept Select Report is signed off, it is not anticipated that any revisions will be required as further project work will be covered in the Design HSE Case. The Design HSE Case may need to go through several revisions during the Define and Execute phases depending on the nature of the design of the new project. The Operations HSE Case shall be reviewed and updated at a maximum interval of 5 years unless any of the following circumstances occur: o o o o o o As part of a Material Change to the Facility, operation or surrounding environment that may have a potential impact on the risk profile When it cannot be verified that the performance of safety critical elements (SCEs) meet the performance standards and/or when mitigation measures have been employed for extended periods to compensate for this shortfall Prior to any material changes to the organisational arrangements or personnel levels Following a major incident involving the Facility or operation, or from lateral learning from other major incidents applicable to the Facility or operation Enhancements in knowledge or technology that change the basic assumptions on which the risk tolerability and ALARP demonstrations are based If there is a change to any of the signatory parties for the HSE Case, i.e. HSE Case Owner (Director), HSE Case Custodian (Delivery Team Leader) or HSE Case Administrator (Technical Safety Engineer) 3.6.2 Material Change A material change is any change that significantly affects the basis for original the ALARP demonstration in the HSE Case. In practice this usually includes changes that have the potential to affect the major accident hazards or their controls, either directly or indirectly. Examples of direct effects are: o Significant modifications or repairs to the plant or equipment, either as single large modifications or multiple smaller modifications. o an increase in hydrocarbon inventory, o new technology, processes or operational complexity, o new types of combined operations, or new activities in connection with an installation, o new operational risk controls. Examples of indirect effects are: o o o Page 17 new ownership or operatorship, introducing a change in the management system, a major change of contractor, and extension of the use of the installation or its components beyond the original design life.

Asset Integrity – Process Safety Management (AI-PSM) describes the way in which PDO assets are managed so that the process risk is as low as reasonably practicable (ALARP). There are two Process Safety implementation mechanisms within PDO: 1. The Process Safety Manual of the Shell Group HSSE Control Framework [Ref. 6] 2. AI-PSM as developed by Centre for Chemical Process Safety Guidelines for Risk Based Process Safety (CCPS RBPS) [Ref. 9]. 4.1 Process Safety Manual, HSSE Control Framework, Section The HSSE & SP Control Framework replaces the mandatory requirements in EP2005 series, and includes mandatory Standards, Manuals, Specifications and Glossary terms, and non-mandatory Assurance Protocols and Guides. The Process Safety Manual of the HSSE & SP CF comprises four elements: 1. Asset Integrity – Process Safety Management Application Manual 2. Design and Engineering Manual 1 (DEM1) 3. Design and Engineering Manual 2 (DEM2) 4. Override of Safeguarding Systems. A full description of each element can be obtained in The HSSE & SP Control Framework [Ref. 6] Compliance to the detailed requirements of the Process Safety Manual is demonstrated by signing a Statement of Fitness (SoF). The Statement of Fitness is shown in section 12 and testifies that the hazards have been appropriately managed in accordance with HEMP and that a suitable and robust ALARP demonstration has been made. The Statement of Fitness is a requirement of the AI-PSM Application Manual and a signed SoF shall be included in Design and in Operations HSE Cases, respectively. For operational assets the SoF shall be signed by Asset Directors, and for new projects by the Project Manager before handover to operations. 4.2 Centre for Chemical Process Safety Guidelines for Risk Based Process Safety (CCPS RBPS) The CCPS RBPS AI-PSM process is an assurance process containing 20 elements 1that describe minimum expected standards and stipulates the requirements for a range of process related activities ranging from organisational culture, workforce involvement, risk management, HEMP and audit through to design. The assurance process includes routine checking, self-assessments and audits, as well as independent 3rd party verification that the AI-PSM system and practices are consistent with industry best practice and are controlling process risk to ALARP. The assurance process also identifies opportunities for improving the management and control of process risk and therefore, is a key driver for continuous improvement. 1 A description of the 20 AI-PSM elements is provided in Appendix 12.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 HEMP is an integral element of the AI-PSM process and the HSE Case and provides a clear link between the two processes. Both the AI-PSM and HSE Case processes aim to identify, control and reduce risk levels to ALARP. 4.3 Process Safety in Projects AI-PS requirements in projects, from project identification through to execution, is described in “GU-648 Guide for Applying Process Safety in Projects” [Ref. 4]. This guideline extracts all the relevant information from the existing ORP documentation that is necessary to meet the AI-PS requirements at handover. It also provides further clarity with regards to the assurance processes which underpin the project team’s ability to demonstrate that AI-PS requirements are met at the end of every project phase. The main objective of this guideline is to explain the key AI-PS objectives and deliverables throughout the project phases that demonstrate the facility is fit for the safe introduction of process fluids and that systems, processes and procedures are in place so that AI-PS can be safeguarded in the subsequent operate phase. This will allow PDO to make the statement that “Our Asset is Safe and we know it” after each project phase. 4.4 Critical Drawings Critical drawings are those drawings which are required to be maintained in order to support the implementation of critical tasks. Critical drawings are required to ensure that the risks from MAHs are ALARP. A list of critical drawings shall be made for each facility. All critical drawings shall be stored in an easily accessible database to reflect the current design and status of the asset (as-built status). This will ensure that all personnel have access to reliable and up to date information to allow accurate planning of work operations and activities, management of change and investigative activities (when an incident has occurred). Critical drawings include, but are not limited to: o o o o o o o o o o o Page 19 PFS PEFS Cause and Effect matrix Hazardous area classification Area Layout Site plan (sub-field layout) Key plan and Plot plan Escape routes Safety equipment layout Critical valve list (including locked open and locked closed valves) Fire and Gas layouts.

HEMP shall be applied to all activities over which PDO has operational control and shall cover the entire lifecycle of the asset or operation; from concept through to decommissioning and disposal. Work undertaken by a Contractor and under the Contractor’s own management system shall have a requirement for an equivalent HEMP approach expressly stated in the contract. HEMP is fundamental to all analysis and assessment elements of the formal HSE activities, and is at the heart of the HSE management system used in PDO. The HEMP process comprises four basic steps: Systematic identification of hazards, threats, unwanted events and their effects Assessment of the risks against screening criteria, taking into account the likelihood of unwanted events and the potential severity of the consequences in terms of effects to people, assets, the environment and reputation of PDO Implementation of suitable risk reduction measures to control or mitigate the hazard and its effects Planning for recovery in the event of a loss of control leading to an unacceptable effect. The main objective of HEMP activities is to demonstrate that hazards (and associated risks) have been identified and where the hazard cannot be eliminated the risks are controlled to a level that is tolerable and as low as reasonably practicable (ALARP). The HEMP model is characterised by Figure 5-1. RISKS TOLERABILITY & ALARP Identify Assess Control Recover DOCUMENT Figure 5-1: HEMP Model HEMP studies shall be performed by staff who are knowledgeable about the facility and operations and who are competent in the HEMP techniques necessary. The studies shall be planned and implemented in a timely manner to enable the results to be incorporated without incurring avoidable rework and costs. The studies should be documented such that key information and decisions made are transparent and available for future reference. Recommendations arising from HEMP studies shall be recorded in an appropriate action tracking system.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 5.1 Hazards and Effects Register Hazards and their effects on people, the environment, the assets and the reputation of PDO shall be systematically identified and listed for the full lifecycle of the asset and operations. The hazards are identified in a Hazard Identification (HAZID) meeting, and the outcome of this meeting is used to develop the Hazards and Effects Register. PDO use a checklist of potential hazards to populate the Hazards and Effects Register. It is recommended that a multi-disciplinary team facilitated by an experienced person go through the list of hazards and identify those relevant to the specific facility/asset/ operation under consideration. Ideally the team should be made up of Management, Operations, HSE, Maintenance and Engineering Disciplines (Concept, Detailed Design as appropriate) personnel. The PDO Risk Assessment Matrix in Figure 2-1 shall be used to assess the hazards and their severity and frequency of occurrence. The experience of the team will be used to brainstorm hazards known to have been realised from previous experience or thinking whether it is a credible hazard that could occur within PDO operations. This is a subjective process and care must be taken not to over-complicate the process by thinking of multiple events, double jeopardy events or highly unlikely events. Examples of credible scenarios could include major leak from oil storage tank at MAF, leak at a Booster station on the main oil line, leak from offtake tanker hose, loss of containment from on-plot processing facilities, loss of containment of H2S (affecting both onsite personnel and the general public). Consequences from such incidents usually cover injury/fatalities, fires/explosions, environmental impact, loss of facility and negative impacts on reputation. For low and medium risk hazards, the controls for the hazards, i.e. permit to work, job safety assessment, operating procedures, competence assessments, tool box talks, etc., are discussed and then added to the Hazards and Effects Register. Hazards that have been assessed as being a severity 5 or high risk on the risk assessment matrix are then modelled further using bow-tie methodology as described in next section. See Appendix 3 for the full checklist of potential hazards, and an example of a Hazard and Effects Register is provided in Appendix 4.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 6 BOW-TIES The Hazards and Effects Register documents that all hazards associated with the facility and that control and mitigation measures have been identified. Hazards that have been assessed as being a severity 5 or high risk on the risk assessment matrix (Figure 2-1) are then modelled further using bow-tie methodology. The Bow-Tie is a model that represents how a Hazard can be released, escalate, and how it is controlled. It contains the elements required to effectively manage the Hazard such that the risks are tolerable and ALARP. Bow-Ties can also be used to support risk management of non-HSE processes. For each severity 5 or high level hazard, the bow-tie methodology allows for: 1. Identification of the hazard release, escalation and consequence scenarios 2. Identification of controls, e.g. barriers and escalation factor controls required to manage the hazards 3. Categorisation of controls into Inherent Safety, Safety Critical Element (hardware) or Critical activity (procedures, processes, operator action) 4. A clear visual representation to enable the ALARP review to be undertaken 5. An aid in the incident review process if occurrence of such a major incident has occurred. The bow-tie is a model that represents how a hazard can be released, escalate and how it is controlled. ‘Bow-Tie XP’ is the PDO preferred software tool Figure 6-1: Generic bow-tie model Page 22 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC Table 6-1: HEMP definitions and Bow-tie terminology ALARP As Low As Reasonably Practicable (Risk) means that having reviewed all practical alternatives for Major Accident Hazard elimination, Threat Controls and Recovery Measures, further reduction in risk would involve disproportionate cost or resources for the risk reduction achieved. Barrier Barriers prevent or reduce the probability of each Threat (left hand side of the bow-tie), limit the extent of, of provide immediate recovery from the Consequences (right hand side of the bow-tie). Barriers may be hardware, such as safety systems (e.g. F&G ESD, etc) or management systems and procedures. Consequence Consequences in the bow-tie are a direct result of the Top Event occurring. Indirect consequences, if applicable shall be modelled in a separate bow-tie, Can include potential consequences that have not been heard of in the industry. Escalation Factor Factors that defeat, or reduce the effectiveness of a Barrier Escalation Factor Control Measures put into place to prevent or mitigate the effects of Escalation Factors. Hazard Any situation with the potential for harm to people, environment, asset or reputation e.g. hydrocarbons under pressure, dropped load. HSE Task Critical An HSE Critical Task develops, implements or maintains the effectiveness and integrity of a Barrier or Escalation Control Factor in Bow-Ties for Severity 5 or High Risk Hazards. HSE Critical Positions are those that execute HSE Critical Tasks HSE Critical Position HSE Critical Positions are those that execute HSE Critical Tasks Major Accident Hazards (MAH) Hazards that are classed as High Risk (Red) or severity 5 on the PDO Risk Assessment Matrix. This means any situation with the potential for major consequences (harm) to people, environment, asset and reputation if released. Recovery Measure Any measure put in place to manage Consequences and assist recovery from a Top Event. Risk The likelihood of a Top Event combined with the severity of the Consequences (The risk is from the Hazard to people, environment, asset and reputation). Threat Any action or mechanism that could bring about the unplanned release of a hazard. Threat Control Any measure put in place to prevent a Threat being successful. Tolerable Risk Tolerable Risks are those that have been reduced to a level where they comply with the applicable laws and regulations, standards, strategic objectives and other agreed Tolerability Criteria. Top Event The first thing that happens when a hazard is released. Individual bow-ties shall have a single Top Event. The role of a barrier on the bow-tie diagrams is to prevent (Left hand side of BT) or limit (Right hand side of BT) the consequence of a major incident. Barriers may be: Page 23 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED.

Able to prevent a specific Threat from releasing the Hazard 3. Verifiable – how shall the effectiveness of the barrier be confirmed? 4. Independent of other barriers in the same Threat line, e.g. no ‘common mode failure’. Hardware Barriers for Severity 5 or High Risk Hazards (HSE) shall be classified as HSE Critical Elements. Selection of these Barriers shall be in accordance with EP2009-9009 SCE Management Manual [Ref. 10]and is further described in Section 7. Common barriers or escalation factor controls that appear frequently, e.g. such as those to do with Operator/Human Error, should be modelled using a separate bow-tie to manage the single Threat of ‘Operator/Human Error’. See Section 10 ‘ALARP demonstration’ for further information. Page 24 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 7 SAFETY CRITICAL ELEMENTS A Safety Critical Element (SCE) is any item of hardware, system or logic software the failure of which could cause a major Accident Hazard (MAH) or whose purpose is to prevent or mitigate the effects of a MAH. SCEs groups are categorised according to Shell EP20099009 ‘Safety Critical Element Management Manual’ [Ref. 10]. These groups or barriers (see section 7.1) contain the definitions of those items that may be classed as safety critical on any given facility. Safety Critical Elements shall be selected from these groups during the bow-tie development process. The bow-tie diagrams show the SCEs as ‘barriers’ to the MAH. A deliverable of the Bow-Tie development process is a list of SCEs applicable to the facility. This list shall be further developed as part of a SCE identification process that defines the safety critical components of each SCE barrier. The role of a barrier on the bow-tie diagrams is to prevent or limit the consequence of a major incident. Barriers may be: 1. Design (inherent) features, e.g. separation distances, reduction of process pressures, minimisation of leak sources, etc. 2. Safety Critical Elements (hardware and logic software), e.g. Process Containment Systems, Pressure Relief Valves, ESD, Fire and Gas Detection, Escape & Evacuation Systems, Breathing Protection, etc. 3. Operational Safety Processes, e.g. valve lock out/tag out, breaking containment procedures, permit to work, etc. 4. Operational Intervention Tasks, e.g. Plant Monitoring, Alarm Response, Shutdown, etc. The SCE management manual [Ref. 10] describes the activities and processes for managing the critical hardware barriers (SCEs) that appear in the MAH bow-ties. 7.1 SCE (Hardware) Barriers Each SCE is grouped under one of 8 hazard management barriers, as depicted in the Swiss Cheese Model (Figure 7-1). The hazard management barriers are as follows: Structural Integrity Process Containment Ignition Control Detection Systems Protection Systems Shutdown Systems Emergency Response Life Saving Equipment Each SCE belongs to one hazard management barrier. Generally, the Structural Integrity, Process Containment and Ignition Control SCEs together with some aspects of the PSD/ESD system, reside on the left hand-side of the bow-tie top event. Failure of any of these barriers could cause or significantly contribute to a MAH. The remaining SCEs normally reside on the left hand-side of the bow-tie top event. These SCEs are provided to control or mitigate the effects of a MAH after it has occurred. Page 25 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Figure 7-1: SCE Hardware Barriers and SCE Groups The hardware barriers in Figure 7-1 are depicted with a number of small holes that represent an integrity failure either in design or operating performance. On their own, these failures may not be significant but, if the holes line up, there may be no effective barriers in place between safe operations and escalating consequences, leading to a major incident. For example, a loss of containment in a sweet gas facility would not normally be expected to cause fatalities unless it is ignited. An integrity failure in the process containment system combined with a failure in the ignition control system could cause an ignited event, i.e. a fire or explosion. If there are no personnel in the area then this in itself would not cause fatalities. However, if there are integrity failures in the fire and gas detection system then the event may not be detected and the process system not isolated and the event may have the potential to escalate to adjacent inventories. This would also be the case if an ESD Valve or Blowdown Valve failed to operate on demand. Finally, if adequate assembly points and EER systems such as emergency telecoms are not provided or are not suitable, then personnel may not be evacuated quickly enough and the process release would have the potential to cause fatalities. The example shows that a number or what on their own would sometimes be considered as ‘minor failures’ have combined to produce a Major Accident causing fatalities.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Figure 7-1 shows the importance of maintaining and monitoring and ensuring the integrity status of all hardware barriers, so that what might be considered to be relatively small faults in individual barriers do not combine together in an unforeseen manner that compromises the ability if the barriers to prevent or control a major incident. Note that it is not necessary for all barriers to fail to lead to a major incident. For example, failure of a single barrier such as process containment on a high sour facility may lead directly to major incident. Each SCE is attached to a relevant discipline who are designated as the owner of the associated Performance Standard. 7.2 SCE Selection SCEs should be colour coded green on the Bow-tie and the specific SCE category denoted beneath the barrier that appears in the Bow-tie. The process for selection of SCEs starts with a review of the generic list of SCE’s provided in the SCE Management Manual [Ref. 10] to identify those SCEs that are applicable to the facilities, for each of the identified Major Hazards. The list of selected SCEs shall be reviewed and agreed by the relevant discipline engineers during the define phase. Figure 7-2 depicts the process for the selection of SCE’s. The HSE Case shall contain a list of the SCEs identified in the bow-tie diagrams as per the table provided in Appendix 5. The HSE Case shall contain a table showing each SCE against the MAH bow-ties where they appear as hardware barriers, and an example is shown for the SCE group ‘Process Containment’ in Appendix 6.

Ye s Is the purpose of this element to prevent a MAH? No Figure 7-2: Selection Process for Safety Critical Elements 7.3 Performance Standards A Performance Standard is a statement, which can be expressed in qualitative or quantitative terms, of the functional performance required of a SCE, and which is used as the basis for managing the risk from the Major Hazards. Defining and ensuring compliance with suitable Performance Standards provides assurance that the SCE is and will remain a barrier to the identified MAH. Generally, the SCEs and Performance Standards follow a one-to-one relationship where each SCE has its own Performance Standard. Performance Standards are used as the basis for design and technical (operational) integrity verification and are expressed in terms of functionality, availability, reliability, survivability and dependencies/interactions with other SCEs. Functionality Functionality is an expression used to define what the system or equipment is required to achieve in order to ensure design integrity. Reliability and Availability Reliability is defined as the required probability that the system or equipment will operate on demand, when required. Availability is defined as the extent to which the system or equipment is required in order to retain its functional integrity. Page 28 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Survivability Survivability defines the external loading events such as fires, explosions or extreme weather, associated with the various MAHs against which the system or equipment is required to retain its functional integrity. Dependencies and Interactions This is used to identify other systems or equipment that are critical to the functionality of the primary system or equipment. By identifying these dependencies and interactions it is ensured that all interfaces have been covered. There are two types of Performance standards; Design Performance Standards. Design Performance Standards must be developed during the Define phase. They shall provide a list of key functional criteria to which the SCE must comply with during the design. In practice the content of the performance standards will be largely taken from the design and engineering standards that apply to the item or SCE. However, other information may be taken from the basis for design, the design philosophies, or the results of workshops and HEMP Studies such as HAZID/HAZOP, Design Review, Layout Reviews, Fire & Explosion Analysis, QRA, IPF, SAFOP, etc. The Design Performance Standards will mature further during the execute phase and will check that the SCEs have been constructed as designed. The existing QA/QC procedures and practices should be used to support the Design Performance Standards. The design must take into account operational demands so that suitability can be ensured into the operate phase. The Design Performance Standards will evolve into Operate phase Performance Standards at the end of the execute phase before handover. Operations Performance Standards. The Operate phase Performance Standards for SCE’s should evolve from the Design Performance Standards. These Performance Standards are formatted to comply with the requirements of SAP-PM and SAP-QM in terms of minimum assurance tasks, assurance measures, assurance value and units of measure for the correct allocation to the appropriate level in the asset hierarchy. Examples of the two types of Performance Standard are provided in Appendix 7 and Appendix 8, respectively. 7.3.1 Performance Standard Approval Each performance standard is allocated an ‘owner’. The owner is responsible for ensuring that the content of the performance standard is appropriate and achievable. The performance standard owner is normally the CFDH for the items covered by the SCE. However, the CFDH may delegate the review and approval of their performance standards to the relevant TA2.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 8 HSE CRITICAL TASKS An HSE Critical Tasks is one that is in place to develop, implement or maintain the effectiveness and integrity of a Barrier, Escalation Factor Control or Recovery Measure Control in the MAH bow-ties. An HSE Critical Position are those that execute HSE critical tasks. The minimum information required for a HSE critical task shall be: The description and purpose of the HSE critical task required The person (position and reference indicator) responsible for performing each task Reference to supporting documentation, e.g. work instructions, SAP, procedure, etc The method and criteria to verify that the task is performed as required to maintain barrier effectiveness. HSE critical tasks should be developed to the level of the party responsible for ensuring that tasks are completed on time and to the required standard, e.g. Managers, Supervisors and Specialists – the position responsible for ensuring that the task is done and not the person who is actually undertaking the work. Bow-tie XP software enables the HSE critical tasks to be linked to the relevant barriers. Inspections and preventative maintenance activities for hardware SCEs are implemented via the Maintenance Management System, i.e. SAP. The task information is contained within the task description in SAP for all SCE barriers and is NOT listed as an HSE critical task, and is considered part of the hardware barrier itself. This applies to for example maintenance and calibration of a gas detector. Implementation tables shall be developed for each HSE Critical Position. The implementation tables describe each HSE Critical Task, its supporting business controls and the business records required to verify that the task is being adequately executed. The implementation tables also provide a link to relevant barriers (HSE Critical Activities) and hazards on the Bow-Tie diagrams. See Appendix 9 for an example extract from an Implementation table. Communication of HSE Critical tasks to affected people in affected position is the responsibility of the HSE Case Custodian.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 9 MATRIX OF PERMITTED OPERATIONS (MOPO) A matrix of permitted operations (MOPO) is an information tool to assist Supervisors and Line Managers during the planning and coordination of operations and activities by providing useful information on: The operation or activity operating envelope and safe operating limits. Actions(s) to take if/when certain situations arise that could compromise safe operations. The MOPO is a set of matrices that maps operational activities against foreseeable situations that if or when they arise could compromise safe operating limits – these situations are identified from: The Threats and Escalation Factors identified as part of the Bow-tie assessments for severity 5 and high risk hazards. An assessment of other operations and activities that could contribute to the escalation of an incident, e.g. continuing with hot work when fire pumps (a safety critical element (SCE)) are unavailable. Circumstances that could compromise safe operations are grouped into three categories: Simultaneous operations (SIMOPs), where large work parties under different management structures carry out work which results in hazards that may impact the other. e.g. removal or overhaul of equipment and/or production and/or construction and/or drilling in the same area (MOPO entitled SIMOPs MOPO) External influences, e.g. extreme weather, visibility, security issues (MOPO entitled Adverse Weather MOPO) Inactive safeguards; i.e. SCE unavailability or impairment, e.g. ESD systems, firefighting systems (MOPO entitled SEC Impairment MOPO). The MOPOs shall identify and differentiate between ‘stop’ (red) conditions, i.e. operation NOT permitted and what are ‘proceed with caution’ (amber) conditions, i.e. continue following appropriate risk assessment and provide additional controls where necessary. All other activities in the MOPO that do not require further assessment or controls are denoted ‘safe to proceed’ (green). For developing a new MOPO or reviewing and updating an existing MOPO, refer to Appendix 10. 9.1 Using the MOPO Copies of the MOPO shall be readily available in a suitable format (poster size, laminated, etc) and displayed in the control room and other operational and job planning /coordination areas. The MOPO shall be referred to during both routine work planning and coordination and in responding to unforeseen conditions. 9.2 Deviations from the MOPO In event of a situation arising where the preferred option is contrary to that given in the MOPO, this shall be assessed and approved by the Delivery Team Leader and relevant discipline authority as defined in DCAF. In the event of a SCE being impacted, relevant discipline authorities shall also be consulted using the FSR process.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 10 ALARP demonstration 10.1 ALARP Definition ALARP (As Low As Reasonably Practicable) allows a proportional level of effort to be put into risk reduction once the initial level of risk has been assessed for a particular operation or process. The ALARP principle is used to determine whether risks are broadly acceptable, tolerable or intolerable via comparison against company risk criteria. The use of the ALARP principle requires judgement to determine whether or not risk levels are as low as reasonably practicable. ALARP can be demonstrated when the sacrifice (cost, time, effort) required to reduce the risk any further, would be disproportionate to the risk reduction potentially achieved (the benefit). The term ‘sacrifice’ relates to the time, effort and/or cost of the complete implementation and future maintenance and operation of the particular risk reduction measure in question. ‘Benefit’ relates to the level of risk reduction offered by a risk reduction measure. ‘Reasonably practicable’ is the balance between the sacrifice and benefit of implementing the risk reduction measure, or suite of measures. ALARP justification also requires demonstration that all risk reduction measures assessed as reasonably practicable have been implemented. The use of ‘reasonably practicable’ uses a goal setting approach to risk reduction rather than a prescriptive one. This is a standard approach for all high risk industries including the oil and gas industry. ALARP demonstration can be based on a comparison of the suite of barriers and control measures that are in place, versus those expected to be seen in equivalent assets or industries. This represents ‘good practice’ and can be identified as standards for controlling risk that have been judged and recognised as satisfying a particular set of laws or regulations. In the absence of a developed regulatory system, company standards, corporate global standards, best engineering practice and engineering judgement may be used as a basis for comparison. For ALARP to be demonstrated, all hazards and risks must have been identified as far as practicable and assessed against the PDO Risk Assessment Matrix (RAM) (Figure 2-1) and as described in Section 5. This provides a prioritised listing of hazards. As a minimum, all Major Accident Hazards (High Risk and Severity 5 hazards) shall be subjected to Bow-Tie analysis as described in Section 6. This is a qualitative approach to demonstrating ALARP using the engineering, process, Process Safety and HSE knowledge and experience of the selected workshop group. In addition to this approach, ALARP demonstration can employ a combination of qualitative and quantitative techniques dependent on the novelty, complexity and type of process or project under assessment. The HSE Cases are assessed in line with the Framework for risk related decision support in PDO as shown in Figure 2-1 and the level of risk assessment performed proportional to the level of risk associated with the process or project. Refer also to GU-648 “Guide for Applying Process Safety in Projects” [Ref. 4] and CP117 “Project Engineering Code of Practice” [Ref. 6] for further description of ALARP requirements.

Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC 10.2 How to Undertake an ALARP Assessment 10.2.1 Principles of Hazard Management The hazard management hierarchy as shown in Error! Reference source not ound. is used to manage HSE risks and shall be referenced when demonstrating ALARP. . Nevertheless, all hazard management controls should be considered at each stage of the development. MOST EFFECTIVE Eliminate Eliminate – Eliminate sources of f lammable gas release Eliminate – Substitute – Eliminate theHouse hazard Substitute Compressor for open arrangement Substitute Substitute Separation –- Isolate/Separate Use processes or from methods with lower Separate c ompressors each other Separate c ompressors from rest of plant Separate gas cloud from ignition sources Isolation / Separation – risk impact Segregate hazards and/or targets Engineered Safeguards – PREVENTION Design f or proc ess containment integrity Engineered Safeguards – Engineer Isolate Engineer Organisation Admin Procedures LEAST EFFECTIVE PPE PPE MITIGATION Gastodetec tion, shutdown, blowdown PREVENTION Design prevent an unwanted event Isolation of ignition sources RECOVERY Design to mitigate harmful consequences Forced ventilation Organisational Controls – Organisational Controls – Training, Competency, Communication Operator training f or Compressor upset conditions Communication for emergency response ProceduralNot Controls - Operating procedures, Work instructions, Permits assessed in Procedural Controls Maintenance regimes Operating procedures quantitative Emergency Response procedures Emergency response procedures terms Personal Protective Equipment Personal Protective Equipment – Protect the person N/ A – there is no PPE effec tive against explosion Figure 10-1: Hazard Management Hierarchy The strategy selected for managing a hazard will differ depending on the project phase, and this principle shall form part of the evaluation when making ALARP demonstrations. As the opportunity for influencing the facility design is greatest during early design phases, the focus shall be on elimination or substitution of the hazards. This typically applies to Identify& Assess and Select phases of the ORP process. As the project matures into Define and Execute, there is less opportunity to apply elimination or substitution and hence the predominant hazard management controls consist of isolation/separation and engineering solutions that can be put in place. Once a facility becomes operational, the hazard management will largely focus on the organizational and procedural controls. PPE is generally regarded as the last principle of hazard management and therefore also the least effective. 10.2.2 Good Engineering Practice In most situations, deciding whether HSE risks have been reduced to ALARP involves a comparison between the control measures a project is proposing and the measures PDO would normally expect to see in such circumstances i.e. the requirements of relevant good practice captured in Company specifications and procedures listed in GU-611. Page 33 SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 The scope for eliminating hazards and threats and reducing the scale of consequences is greatest at the beginning of the project and progressively reduces as the project develops. In part this is because the cost and difficulty of delivering a given risk reduction solution increases as the project develops. ALARP demonstrations must be robust for each of the HSE Cases as per Figure 3-1. CP-122 “Health, Safety and Environment Mgmt System – CoP” describes application of the AI-PSM process from CCPS RBPS within PDO to demonstrate compliance to good engineering practice and to ensure that risk levels are ALARP. This is made via demonstrating compliance against the 20 Process Elements shown in Appendix 12. 10.2.3 Good Engineering Principles Company specifications and engineering standards should be followed unless there is sound justification, and then consideration given to whether there is any more that can be done to reduce the risk. If there is more that can be done, these further measures need to be assessed by comparing the risk reduction with the cost and effort involved in further reducing it. Simply following standards does not in itself demonstrate ALARP, particularly for more complex or novel projects, where additional considerations shall be made. 10.2.4 HEMP Studies HEMP studies undertaken during the select, define, execute and/or operate phases of the development are used to assess risk levels and identify any further risk reduction measures. Applicable HEMP studies for each project phase are defined in DCAF. 10.2.5 ALARP Review In assessing the risks associated with the Design or Operations HSE Case hazards, a qualitative review of the Bow-ties shall be undertaken. The review shall be led by an experienced facilitator and the review team shall be comprised of experienced staff from the following areas of expertise: o o o o o o o Engineering Process HSE Maintenance Operations Management Asset stakeholders. Each of the threat lines in the bow-ties shall be reviewed in turn and the discussion should cover such questions such as: o o o o o Page 34 Does industry best practice state what should be done or make any recommendations? Can a benchmark exercise be undertaken against other operators and similar controls implemented? Where are the gaps/shortfalls and what action needs to be taken to address these gaps/shortfalls? See Section 11.2. Is there sufficient quantity and quality of barriers? Is there anything else that can be done to further reduce the risk?

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 Both barrier effectiveness and the number of barriers contribute to the overall effectiveness of control, although in general, the effectiveness of individual barriers is more critical. The number, independence and reliability of the control and recovery measures shall be commensurate with the risk. By approaching the bow-tie review in this systematic fashion, the barriers can be challenged in terms of completeness and adequacy and gaps identified and addressed so that the review team is satisfied that the risks arereduced to ALARP. The HSE Case process enables an ALARP argument to be formulated although in isolation, a complete ALARP argument cannot be made. The claims made against the numbers, quality, performance and location of the barriers must also be verified. This verification of the safeguards (both hardware and procedural controls) is performed via AI-PSM audit and the TR-MIE and TI-HBV processes. These processes substantiate the claims made within the Bow-Ties and MOPO in terms of barrier integrity and performance. 10.3 Assessment of Complex Decisions Demonstrating ALARP shall involve consideration of fundamentally different options to provide assurance that the Company gets the best value for money over the lifetime of the facility. The assessment of fundamentally different options normally takes place in the identify, assess and select phases. Assessment of complex decisions requires consideration of all the hard and soft issues related to a range of options and should reflect a decision taken at the right level in the organisation with full knowledge of all the options and their associated risks and costs. The following structure is recommended for documenting ALARP demonstration for complex project decisions: 1. IDENTIFY a. Problem Definition b. HSE Issues and Potential Risk c. HSE Standard & Tolerability Criteria 2. ASSESS a. Options Considered b. Basis for Selection and Uncertainties c. Justification for Chosen Option 3. CONTROL & EVALUATION a. Residual HSE Risks b. Recommendation for Next Project Phase c. Requirements for the Operations HSE Plan/Case The ALARP demonstration for such decisions shall be signed by the person developing the demonstration as well as relevant discipline Technical Authorities.

Petroleum Development Oman LLC Revision: 1.0 Effective: Mar-11 11 OPERATE PHASE CONTINUOUS IMPROVEMENT 11.1 Drivers for Improvement Key Performance Indicators (KPIs) have been established for the AI-PSM programme within PDO. AI-PSM KPIs consist of: o o A set of KPIs defined by Operational and Functional Leadership, collected on a uniform basis at all assets (Corporate KPIs). Any additional asset-specific KPIs targeted at the key risks of that asset. Typical AI-PSM KPIs include: o o o o o o o o o Number of Process Safety incidents reported YTD. Number of Process Safety near misses reported YTD. Percentage compliance with Level 2/3 audit schedule. Number of deviations/non-compliance with PTW discovered during worksite visits (in the quarter). Number of approved waivers, forces and safeguarding overrides in place. Safety Critical Element corrective maintenance compliance. Safety Critical Element preventive maintenance compliance. Number of overdue actions arising from Process Safety studies (HAZOP, OBRA, FERM, TI-HBV, PSBR, Incident investigations, LEVEL 1/2/3 AI-PSM audits, PSUA). Number of SCEs that failed to meet Performance Standard (per quarter). 11.2 Remedial Actions Action items can be raised during compilation of a new HSE Case or review and update of an existing HSE Case. These areas for improvement in the systems or controls in place to manage Major Accident Hazards need to be addressed to ensure that operations continue to be maintained at ALARP. All action items raised shall be reviewed and approved by the action party and the HSE Case Custodian prior to be entered into the HSE Case and the action tracking system (FIM) for close out. The HSE Case Administrator is responsible for ensuring that actions are closed out in a timely manner. The HSE Case Custodian has overall responsibility for ensuring all technical information within the action close out is correct and complete. Target dates are dictated by the most reasonably practicable timescale within which the actions can be completed. Items in the remedial action plan (RAP) must be rectified in accordance with the timescales set out. Where an action is not to be taken because the cost and resources required to complete the action are not considered reasonably practicable in view of the benefits gained in risk reduction (ALARP evaluation), this is stated in the RAP.

Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC 11.2.1 Qualitative Analysis of RAP Items Risk reduction measures, and in particular those warranting the implementation of additional safeguards, shall be compared against a simplistic cost benefit matrix, as detailed in the ‘Cost, Benefit, Effort Multiplier’ in Table 11-1. This results in each of the potential risk reduction measures being categorised as: o o o Do - Implement the option Study - Investigate the option further and implement if practicable Pass – Review category to confirm rating, if still assessed as Pass, record decision making process and do not invest further effort. Review in future for practicability. The decision on whether to take the action shall be dependent on the resulting score. The multiplication results in a numerical score from 1 (most attractive) to 27 (least attractive). The result of this iterative process shall be tabulated in the Remedial Action Plan within the HSE Case.

It clarifies the context in which the selection decision has been made, the data that have been used, the alternatives that have been studied, and the values and trade- offs between alternatives. The purpose of the HSE content of the Concept Selection report is to: 1. Demonstrate that there has been a systematic application of HEMP during the Identify & Assess and Select Concept phases of the ORP [18] for each option being considered; 2. Confirm that the lowest risk option have been actively sought and selected; or alternatively, demonstrate that the cost/effort required to adopt the lowest risk concept is grossly disproportionate to the benefit (ALARP). The HSE content of the Concept Selection report shall include: o o o o o o o o o Reference to descriptions of the options being considered; A Hazards and Effects Register in accordance with EP Tool ‘Hazards and Effects Register’ [14] for each development option considered; Summary of the risk profiles associated with each option; A summary of the HEMP studies and key assumptions that have been made in the Hazard identification and risk assessments studies; Summaries of the philosophies and measures implemented during this phase to reduce residual risks to ALARP The justification that the selected option shall present the lowest overall risks, or alternatively, the ALARP demonstration showing that the cost/effort required to adopt the lowest risk concept is grossly disproportionate to the benefit; Any issues that may have an impact on the risk profile and so need to be addressed during the Define and Execute phases. Summary of rejected options with a description of reason for not pursuing the respective options. SIMOPS considerations for Sour projects Relevant HEMP studies will depend on the nature, size and complexity of the project.

Printed 28/07/17 Petroleum Development Oman LLC Appendix 10 Revision: 1.0 Effective: Mar-11 MOPO The team to develop or review the MOPO shall consist of operations, maintenance, HSE and management personnel who are familiar with the operation of, and the activities required, at the facility/asset. The team shall be lead by an experienced facilitator and shall: Identify Threats and Escalation Factors in the Bow-ties that could compromise safe operating limits. Identify other operations and activities that could compromise safe operating limits. Develop the MOPO under the appropriate headings of SIMOPs, External Influences and Inactive SCE Identify the ‘stops’ and ‘proceed with cautions’ using the red/amber traffic light system. Provide supporting guidance notes for the ‘proceed with cautions’ that will assist Supervisors etc if/when the situation arises. Collectively review the matrices and ensure they reflect current practise and give clear guidance for action to be taken under the specific circumstances. A number of assumptions are used in the template MOPO: The SIMOPs MOPO shall assume that two or more major activities, e.g. production, drilling, are simultaneously being performed in the same location/area. The Impaired SCE MOPO shall assume that the operation is in the vicinity of, or within the area affected by, the impaired SCE. The Impaired SCE MOPO shall define the minimum level failure mode assessed as having an impact on one or more of the high level activities/operations. Failure modes below this level shall be subject to risk assessment and remedial action in accordance with EP2009-9009. When SCEs are in test mode, alternative controls shall be put in place to ensure that their functionality is provided. Testing of these systems is not generally considered ‘impairment’ for purposes of this MOPO. In case multiple barriers are unavailable/impaired, the combined effect of the simultaneous failure on the activities shall be subject to risk assessment. Additional controls required as indicated in the MOPOs (coloured amber) shall be listed. Wok shall only be carried out under the formal control of the Permit to Work (PTW) system, including component elements such as plant isolation certificates, vessel entry certificates, hot work permits, etc. All applicable procedures and work instructions relating to the work to be undertaken shall be complied with. In certain cases, the specific operation is not directly impacted by the barrier that is impaired, but consideration shall be given to proceeding with non-essential work that could increase the risk. Where necessary, the requirement for undertaking risk assessment shall be noted. Measures shall be taken to maintains risks at ALARP and the effectiveness of the measures shall be verified. All actions involving bypassing the safeguarding systems shall be authorised by the Production Delivery Team Leader who shallprepare individual procedures for all tasks not covered by existing procedures and consult relevant discipline technical authority. Examples of the three MOPOs (Adverse Weather, SIMOPs, and SCE Impairment) follow. These shall be used as guidance for construction of a new MOPO or for review of an existing MOPO. The notes within the MOPO are intended to support rather than supersede the specific risk assessments required, particularly for SCE Impairment where FSR and CMPT processes shall be applied. For a MOPO to be effective it must provide clear concise information to the Operator of immediate action to be taken under the specified conditions, e.g. if working at height is ongoing and wind speed increases, he needs to be able to quickly see when to stop the activity in question.

Any proposed changes (e.g. engineering, procedural, organisational) that have an impact on the risk profile of the Facility or Activity, shall be managed in accordance with this Procedure (including an ALARP Demonstration) and the HSE Case shall be updated accordingly. The possible changes that might affect the HSE Case and its underlying assumptions are those listed in Section 13. Step 2: Assess Impact of Change(s) and Develop Workscope a) Determine whether the proposed changes(s) will affect the Case content or its underlying assumptions. If it is agreed that there is no effect on the Case or its supporting studies, no further action is required. b) Where it is agreed by there is an effect on the Case, develop workscope with relevant Stakeholders. c) Ensure that the workscope includes review and update, as required, to: i. HEMP Studies and ALARP justification; ii. QRA Studies; iii. Bow-Tie assessments; iv. HSE Critical Element and Performance Standards; v. HSE Critical Task listings. d) Agree and record actions with originator, action parties and Stakeholders. e) Summarise details of the HSE Case Change Approval Form f) Logs the HSE Case change in the HSE Case MOC register. The register should ensure that all changes to the HSE Case are grouped together for review and to allow assessment of cumulative effects or risk. Step 3: Perform Workscope a) Perform agreed workscope as identified in 2b above. b) Representatives from the current operational, engineering and maintenance teams, and workforce involvement representatives shall actively participate in performing the workscope as appropriate. c) Review outcomes for actions to determine final impact. d) Consult with Stakeholders on effect on HSE Case (where appropriate). e) Complete change(s) to relevant documents/processes/drawings etc. supporting studies or other associated Step 4: Prepare HSE Case Change(s) a) Prepare change(s) to HSE Case in consultation with action parties and Stakeholders.

Revision: 1.0 Effective: Mar-11 Petroleum Development Oman LLC Step 5: Review Proposed HSE Case Change(s) a) Issue the HSE Case Change Approval Form with proposed change(s) to the HSE Case to relevant action parties and Stakeholders for comment/review. b) Amend proposed change(s) as required reflect any comments received. On the HSE Case Change Approval Form annotate which sections of the HSE Case have been changed. c) Determine need for immediate publication of change(s). Consider whether change is significant and needs immediate update. Also consider cumulative effects of changes to date. Step 6: Approve Change(s) a) Gain acceptance of proposed change(s) from relevant parties, including sign-off of HSE Case Custodian (obtain signatures). b) Update status of HSE Case Change Approval Form in the HSE Case MOC Register including ‘Date Agreed’. c) If applicable, update FIM to record any changes that affect any open items still under review (e.g. Change to HSE Case Remedial Action Plan). Step 7: Publish Change(s) a) Make change(s) to HSE Case. b) Publish HSE Case on Livelink / issue to document copy holders. c) Update status of Update status of HSE Case Change Approval Form in the Change Register including ‘Date Completed’.

Petroleum Development Oman LLC Appendix 12 Revision: 1.0 Effective: Mar-11 CCPS RBPS Process Safety Elements The AI-PSM process within PDO identifies 20 elements from the Centre for Chemical Process Safety Guidelines for Risk Based Process Safety (CCPS RBPS) which describes minimum expected standards and stipulates the requirements for a range of process related activities ranging from organisational culture, workforce involvement, risk management, HEMP and audit through to design. ELEMEN T NUMBER AI-PSM ASSURANCE ELEMENT 1 Process Culture 2 Compliance Standards 3 Corporate Process Safety Competency 4 Workforce Involvement 5 Stakeholder Outreach 6 Process Knowledge Management 7 Hazards and Effects Management Process (HEMP) 8 Operating Procedures 9 Permit to Work Page 83 Safety with ELEMENT AIMS AND OBJECTIVES To establish and reinforce high standards of process safety performance through the organisational norms for employee and contractor values and behaviours at all levels in the organisation. To ensure that the facility conforms to the applicable standards, codes and regulations so that the facility operates in a safe and legal fashion. A key aspect of demonstrating commitment to process safety, the process safety competency element is about developing, sustaining and enhancing organisational competency. This is different to individual competency assurance (which is covered in element 12). The key concern here is the concept of the ‘learning’ or ‘transformational’ organisation Personnel at all levels of the organisation should have roles, responsibilities and opportunities to effectively contribute to process safety programmes. This element ensures that a system is developed for enabling the participation of operators, technicians and contractors in the development and implementation of process safety activities through employee participation To ensure that internal and external stakeholders to the organisation are identified, and that their information needs are understood and adequately met. To enable risk assessment and risk-based process safety. Understanding process risk depends on having accurate process knowledge, and without an understanding of process risk, process safety can never be assured. To enable risk assessment and risk-based process safety. Understanding process risk depends on correctly and completely identifying the hazards associated with the operation, and accurately assessing the risks posed by those hazards. Without an understanding of process risk, process safety can never be assured. A consistent high level of human performance is essential for a successful process safety programme. Up to date clear operating procedures assure that the intended and proven methods and techniques are applied consistently. To ensure that the risks associated with non-routine work are managed in a systematic way through the application of a permit-to-work system and operations / maintenance procedures (which are described in the previous element) SP-2062 Specification for HSE Cases Printed 28/07/17 The controlled version of this CMF Document resides online in Livelink®.

A consistent high level of human performance is essential for a successful process safety programme. Training and performance assurance provides confidence and demonstration that work tasks will be consistently completed to the required standard, and that personnel have the knowledge and ability to respond appropriately to non-routine situations. To ensure that changes made to plant equipment or technology, or to the Organisation operating the equipment, do not result in the inadvertent introduction of new hazards and risks, or unknowingly increase the risk from existing hazards. To ensure that equipment is safe to start-up and operate, and that the activities necessary to ensure continued fitness for service have been put in place. It covers start up of new equipment, modified equipment and existing equipment restarting after a plant shutdown To create an organisation that demonstrates excellence in the performance of every task, and has zero tolerance for deviations. To reduce the consequences of a major accident and to save lives, protect property and the environment. To learn from incidents and near misses and to prevent them from recurring. Identifying and correcting systemic incident causes will not only help prevent a repeat of that incident but by strengthening the AI-PSM management system can prevent other incidents. To provide a means for near-real-time monitoring of the performance of the AI-PSM system, and so indicate whether process risk is being managed as low as reasonably practicable and in line with company criteria for tolerable risk. To reduce risk by systematically and pro-actively identifying strengths and weaknesses in the implementation of AI-PSM. To ensure that the defined AI-PSM activities produce the desired results throughout the facility lifecycle.
