1.

PURPOSE The purpose of this document is to define the Terms of Reference for any Hazard Identification (HAZID) or Hazard Analysis (HAZAN) Study that will be carried out by or on behalf of DBP. This document outlines the methodology, workshop process, team composition and the information required for the study.

2.

SCOPE This procedure applies to any HAZID or HAZAN conducted for or on behalf of DBP. A HAZID is to be conducted whenever there is a Project, as defined in the DBNGP Safety Case, or new activity being conducted in relation to the DBP systems. The HAZID is to be conducted prior to the commencement of the Project and/or works and prior to the completion of procedures and documentation that may or may not require submission to the Regulator. A HAZAN is to be conducted after commissioning of a Project or works and prior to handover to identify any hazards and also any training requirements for new equipment or systems. The HAZAN includes a review (by physical inspection by appropriate personnel) of the completed Project or works, updating of punchlists and a review of punchlists for hazards for inclusion in the HAZAN register and appropriate assessment as per this procedure. The scope of each HAZID/HAZAN will include all aspects of activities being conducted. For example, if this scope is defined under a safety case, then the entire scope of that safety case will be subject to a HAZID/HAZAN. It should be noted, however, that the entire scope may not be covered during one workshop and may be split into several focussed workshops to ensure appropriate attendance, knowledge, experience and time to achieve the objectives of the workshop. The scope of each HAZID/HAZAN will be clearly defined in the completion and approval of the HAZID/HAZAN Study Request Form (HSE 429-1 FM). The HAZID_HAZAN Study Request Form (HSE 429-1 FM) will be completed as part of the planning and preparation of a HAZID or HAZAN and will define the scope the study, nominate the facilitator and identify attendees and provide adequate information for the DBP HSE Manager to approve the workshop to proceed as planned.

TERMS OF REFERENCE

7.1

Objectives The purpose of the workshop is to brainstorm and identify hazards that have the potential to affect personnel, assets, production or the environment. These hazards will be assessed against existing policies and procedures and where appropriate, additional mitigation measures and actions will be assigned for resolution, close out and monitoring. The objectives of the workshop are to: •

Identify and systematically assess all major hazards and potential incident events associated with the relevant activities;

•

Identify existing or planned mitigation measures (physical, procedural and recovery);

•

Evaluate the identified risks;

•

Where necessary, make recommendations to eliminate or reduce risks;

•

Identify hazards with a potential consequence of a single fatality;

•

Identify Major Accident Events and assess if not already part of the existing DBP register;

•

Record the workshop findings; and

•

Provide a basis for the ongoing monitoring and closure of associated actions.

7.2

Methodology The risk assessment framework that will be applied to this study is in line with the Australian Standard AS/NZS ISO 31000:2009. The risk management process will concentrate on the hazard identification and risk analysis and mitigation components of new or additional hazards. Effective safety and hazard assessment requires a systematic approach, to the identification of hazards and issues. A basic introductory presentation (HSE 429 PPT) is to be provided to the study group by the workshop facilitator to ensure a common understanding of the risk management concept and the workshop process. A structured brainstorming process is to be used for the study, consisting of: •

definition of the study objectives and area to be studied by the facilitator and/or Project Manager;

•

outline of activities involved in relevant activities by the facilitator or Project Manager. For a HAZAN, this may be supplemented with a physical inspection of the completed works;

•

brainstorming the hazards and their causes assisted by use of a guideword checklist (HSE 429 GW) when necessary;

•

review and use of existing hazard registers relevant to the workshop scope to ensure identification of all potential hazards and benefit of experience and lessons learnt from previous activities;

•

determination of worst case credible consequences (note that this can be reviewed after existing safeguards are identified to ensure that the consequence identified is credible);

•

identification of the existing safeguards (management control and mitigation systems and procedures);

•

determination of the likelihood of the consequence occurring (taking into consideration the existing safeguards in place);

•

assessing the risk associated with the identified hazard;

•

identifying actions where deemed appropriate or to address the risks deemed unacceptable or not ALARP;

•

identification or training requirements or similar, particularly if new equipment has been installed or changes have occurred to equipment or processes as a result of the Project or works; and

•

Confirmation of MAEs in existing registers or assessment of new MAEs for Performance Standards in accordance with the Safety Case.

The workshop team will be a multi-disciplinary group comprising engineering and construction, commissioning or operations and maintenance personnel as appropriate and people with specialist health, safety and environmental expertise. The attendees shall include representation from employees (required) and contractors, as appropriate. An attendance register will be completed as a record of those contributing to the workshop outcomes and signed by each person attending (HSE 429-2 FM).

The proceedings of the workshop session will be recorded using standard Excel (Microsoft) software (HAZID_HAZAN Workshop Risk Register HSE 429 XLS) and will be reviewed by all participants to observe and agree with the recorded information. The records of the workshop must be adequate and comprehensive to ensure that a third party can review the outcomes and understand the thought processes and discussions that progressed within the workshop to record those outcomes. This is particularly important with regard to ensuring that all mitigations are relevant to the causes and when documenting when an event or consequence is not credible. 7.3

Risk Model All credible hazards and risks identified during the workshop will be ranked against the DBNGP risk model. The DBNGP risk model has been designed based on pipeline construction and operational experience. The use of the DBNGP risk model and risk identification and assessment template will be a baseline for the ongoing review and update of the existing documentation in accordance with the DBNGP Safety Case.

7.4

Hazard Identification The process to be followed during the workshop is illustrated in Figure 1 below. This method will allow a brainstorming exercise to be applied to the workshop scope to identify potential hazards. Checklists as detailed in HSE 429 GW can be used during the workshops to assist in the identification of hazards. Once a hazard has been identified, potential causes and consequences of the event occurring, as well as existing safeguards will be identified by the workshop team. The brainstorming process is an essential part of the workshop. This enables free flowing discussion amongst the workshop attendees while also discussing and understanding the scope of work. The facilitator should ensure that all hazards (and potential causes and mitigations) are adequately recorded on a white board, or similar, to enable the workshop attendees to see the ideas of the group. These brainstorming outcomes should remain visible throughout the workshop to ensure that they can assist in stimulating the workshop ideas. Near the conclusion of the workshop it should be reviewed and the workshop attendees agree that all items have been adequately discussed and recorded.

7.5

Risk Management Framework The risk assessment framework that will be applied to this study is in line with the Australian Standard AS/NZS ISO 31000:2009. The risk management process concentrates on the hazard identification, risk assessment and risk mitigation components. The risk assessment framework is consistent with the requirements of the DBNGP Safety Case and the results and outcomes will form part of the Formal Safety Assessment and demonstration of the case for safety. The following summary has been extracted from AS/NZS ISO 31000:2009: •

Risk management is an iterative process consisting of well defined steps which, taken in sequence, support better decision-making by contributing a greater insight into risks and their impacts. The risk management process can be applied to any situation where an undesired or unexpected outcome could be significant or where opportunities are identified. Decision-makers need to know about possible outcomes and take steps to control their impact.

•

Risk management is the term applied to a logical and systematic method of establishing the context, identifying, analysing, evaluating, treating, monitoring and communicating risks associated with any activity, function or process in a way that will enable organisations to minimise losses and maximise opportunities. Risk management is as much about identifying opportunities as avoiding or mitigating losses.

7.6

Risk Determination The workshop team shall rank each identified hazard according to the potential consequence and likelihood of occurrence with existing safeguards in place. The workshop will facilitate a consensus decision on the likelihood or consequences of a hazard, and promote brainstorming and open discussion of complex hazards for which information is not readily available. The consequences are dependent on the potential impact of the event in the first instance. All safety hazards consequences will be assessed in terms of injury severity and the potential number of fatalities. Quantities and concentration released, time scale of release, the severity of potential receptors and regulatory requirements will be considered for environmental hazards. The DBNGP Risk Model shall be used to assess the severity (or consequence) and likelihood (or frequency) of any identified incidents, for safety and environment respectively.

Through the ranking process, consideration will be given to the magnitude of the consequences and likelihood of a hazard. Risk evaluation helps to prioritise the risks; i.e. determining whether the risk of an activity or incident is acceptably low, or if management actions are required to reduce the risk to ALARP. The criteria to be used during the workshop for evaluating the acceptability of the risks are shown on each risk matrix. It is the intention to manage the demonstration of ALARP for the operation and maintenance activities during the workshop session using the benefit of the group assessment. Where hazards are identified and associated risk ranked in the ALARP region, every effort will be made to identify measures which could reduce either the consequence or the likelihood of the event occurring. Hazards identified with a potential to have more than one fatality as a consequence will be recorded as a Major Accident Event (MAE) as per the DMP Regulations. DBP requirements are that any Hazard identified with the potential for one or more fatalities will also be recorded. Both will be discussed in the workshop report (HSE 429 RT). The safety case regime is a regulatory initiative focused on addressing potential for MAEs while continuing to address occupational health and safety. The DBP safety management system must specify the performance standards that apply. The performance standards are the parameters against which control measures for MAEs are assessed to ensure they reduce the risks to ALARP on an ongoing basis The risks associated with each of the hazards will be assessed qualitatively, however if necessary quantitative assessment will be undertaken when a hazard cannot be adequately reduced to acceptable in accordance with the DBNGP Risk Model through qualitative measures. Any Risk Reduction Measures (RRMs) identified during the workshops will be assigned to a relevant person for resolution and closeout. Implementation of the RRMs where practicable will assist with the demonstration of ALARP. 7.7

Mitigation Measures The control measures for the reduction of potential hazards to ALARP status must be robust, reliable and measurable to provide for the reduction and elimination of risk factors. Mitigation Measures – Physical, Procedural and Recovery mitigation measures are required Physical Mitigation Measures These measures can be as simple as barriers and surveillance and as complex as control systems that rely on software and other technology. The measurement of the survivability if the control systems such as fences, barriers etc is simple and can be verified by physical inspection and surveillance over time and the choice of materials in the first instance. The survivability of control system reliant on software and other electronic controls is somewhat more difficult and will rely on the use of proven technologies and backup and fail safe mechanisms.


Page 12 of 17

DBP Procedure:

The reliance on qualifications and staff and contractors will affect the robustness of this area and will be reinforced by the use of strong Procedural Controls. Procedural Mitigation Measures Procedural controls relate to all areas from Corporate and Regulatory regimes to construction and maintenance policies. Training of staff and the implementation of QA systems and the ongoing Audit process of performance of both staff and procedures will be the be the key to survivability of these control measures. Recovery Measures Recovery mitigation measures relate to all those that can be implemented to minimise the impact of the hazard should it occur. These include aspects such as first aid kits, first aid trained personnel and Emergency Response Plans. 7.8

MAE Mitigation Measures Measurement The ultimate measurement of the Controls is the lack of any MAE but the individual controls need to have some form of measurement to allow the reduction of the risk to ALARP where possible. The reporting and recording of all aspects related to the control, i.e. breaches of security, corrosion reports, staff training reports and subsequent benchmarking against required standards to assess the level of compliance will then flow on to the remedial actions required to prevent the likely hood of an MAE. Functionality (How is the control designed to control the risk?) The control needs to be functional for the purpose proposed and be able to be implemented in a manner that will not increase or produce its own risk that will impact on the cause it is to control. For instance if physical barriers are to be installed to protect a facility the installation should not compromise the integrity of the installation, and similarly the design of piping etc to mitigate rupture should not lead to higher risks in construction and maintenance . Reliability / Availability (How do we prove the Control is reliable, properly maintained, monitored and works when required?) Physical inspection and the ongoing Audit process are to be used to monitor the performance of the Controls and will require reporting formats to verify the process. The use of Industry Standard and Best Practice training for all staff involved in the assessment of controls is an essential and is also a Control in its own right. Where software and technology is used to implement the Control it is essential that there are backup systems and failsafe systems to support the this function. Apart from the obvious use of programmed testing as for devices such as fire and other sensing devices regular inspections and scenario exercises can play an important part in this phase of the exercise. The use of Third Party validation of reports and procedures is encouraged as an option in areas where it is applicable. Survivability (How is the integrity of the control maintained through change and major events?) To ensure the longevity of the Control it will need to be supported by the structure of the organisation with inspections, methodologies, Regulations and documentation in place to


Page 13 of 17

DBP Procedure:

be capable of managing change in both the physical aspects of the organisation as well as the Management changes that inevitably happen in large organisations. This requires staff and Management to be capable of managing change in all aspects. Measurement (How do you gauge the effectiveness of the control?) Zero MAE is the ultimate measure of the success of the control. The measurement of any breaches of the control or compliance with the prescribed measures and benchmarks will give an indication of the potential success of the Control and when it is found that the Control is below the required standard, a review of the Control or the aspects of Functionality, Reliability / Availability or Survivability will be required to remedy the problem area. 7.9

ALARP Once a risk rating has been determined, the acceptability of the ranking will be determined using the DBNGP Risk Model. Where the risk rating cannot be reduced to 'Low' or 'Negligible', to demonstrate ALARP it is necessary to review if it is reasonably practicable to remove threats, reduce frequencies and/or reduce the severity of consequences and if it is reasonably practicable, these risk treatment actions shall be applied. After consideration, discussion and documentation of potential further mitigation measures, if it is not reasonably practicable to implement those potential measures, all discussions will be recorded, no further action is required and ALARP is demonstrated. ALARP is defined as “the cost of further risk reduction measures is grossly disproportionate to the benefit gained from the reduced risk that would result”. Determination of practicable can also depend on "value judgements" of the individual, group, workplace, industry, social and legal standards. In the assessment of ALARP, the risk workshop attendees will discuss the “What else could we reasonably do to reduce the risk?” on each hazard that is identified.

7.10 Workshop Outcomes A number of specific requirements detailed below will be reported on: •

Review Project documentation to gain an understanding of the project, scope and potential health, safety and environmental hazards and risks associated with relevant phase of the Project.

•

Act with the endorsement of the Licensee and approval of HSE Manager.

•

Identify the processes, balance of plant and systems associated with the relevant scope.

•

Using available information and the knowledge and experience of the workshop participants, list identifiable hazards during the relevant phase of the Project and associated support activities such as travel.

•

Assess the potential consequences and likelihood of exposure to each hazard.

•

Develop and agree on appropriate control measures for each hazard and where required assign specific actions and responsibilities to ensure control measures are in place prior to mobilisation.


Page 14 of 17

DBP Procedure:

•

Assess the risk level associated with each hazard for the existing treatments/controls related to the hazard and the level of risk when any additional agreed controls have been implemented.

•

Document the process of ensuring that the controls for each hazard are sufficient to reduce the risk level to As Low As Reasonably Practicable (ALARP) in line with the DBNGP Risk Model. This will include the clear record of hazards that fall into the ALARP region and the justification for the determination of ALARP.

•

Document Major Accident Events (MAE’s) and all relevant discussion.

•

Document intolerable and unacceptable risks and all relevant discussion.

•

Document and summarise hazardous events falling into the various risk categories.

•

Document the finding of the workshop process in a Hazard Register and incorporate the agreed control measures into the DBNGP Safety Case and/or associated documentation and systems. Any changes to existing hazards identified will be recorded with an action to ensure that all relevant O&M documentation and processes are updated to reflect the change.

•

Document all assumptions and uncertainties pertaining to the workshop.

•

Clearly document recommendations applicable to the further application of findings of the workshop, including the application of the DBNGP risk model.

•

All hazards identified with a ‘People’ consequence of more than one fatality will be recorded as a Major Accident Event (MAE) and included in the DBNGP Safety Case and associated documentation where appropriate.

•

Applicable requirements of the Petroleum Pipelines Act 1969, Petroleum Pipelines Regulations 1970, the Pipeline Licence PL40 and PL47, directions issued under PL40 and Pl47, The Schedule of General Requirements for Occupational Health and Safety 1993 shall be referenced and met.

•

The DBNGP Risk Model shall be used.

•

All the reports required to be produced shall be signed and dated by the facilitator signifying approval.

The workshop register and associated report shall be written and recorded in a manner that enables a third party to review the register and understand the thought processes used to reach those outcomes. This requires recording to be thorough and provide adequate explanation for assumptions and outcomes, including how a mitigation measure being applied may mitigate the hazard (i.e. PPE – gloves provides information that the gloves are the relevant PPE that may mitigate against the hazard rather than a generic PPE statement). At the conclusion of the workshop the HAZID_HAZAN Workshop Compliance Checklist (HSE 429-3 FM) is to be completed and endorsed by the Project Manager, The Facilitator, The Scribe and a contractor representative. 7.11 Actions Management and Close Out All the actions raised during the workshop will require monitoring, review and close-out in line with times nominated during the workshop by the party nominated to complete them.

DBP will have an overall responsibility for management of actions and their timely completion. Individual actionees have a responsibility to provide documented details of the action / recommendation closure methodology and timing. Some hazards may not be able to be assessed for ALARP, if required, at the time of the workshop. These hazards will be recorded with an action for further consideration and subsequent assessment for ALARP and be nominated to an actionee for responsibility for close out of that action. The Hazard Register will be maintained as a live document and entered into a suitable and relevant action management system, to record and track all identified risk events, controls & mitigations and closeouts. It is a requirement that the Hazard Register be reviewed by all personnel implementing the works and it be used to assist the preparation of JHAs for work tasks. The Hazard Register must be reviewed and understood prior to the commencement of works. 7.12 Deliverables The documentation developed during and as a result of the HAZAN Workshop will include: •

HAZID/HAZAN Report (Template = HSE 429 RT) ;

•

HAZID/HAZAN Closeout Register or system for monitoring close out of actions; and

•

HAZID_HAZAN Workshop Risk Register HSE 429 XLS.

The Report will detail the methodology used and the main outcomes of the risk assessment process. Actions identified during the workshop will require close-out within the time frame specified. The Closeout Register will manage the action closure responses for each action raised. The reports will be issued to DBP, Regulator and other third parties, as required.

AUDIT Each project should be audited to ensure that the controls identified within the HAZID are in use and effective. The focus of this Audit will be on compliance with the Statutory HSE obligations and implementation of the specific elements detailed in Project Construction HAZID, Safety Case Addendum, Project CEMP Bridging Document and the Project Emergency Procedures. The audit process should involve the following activities: •

Contact established with DBP or Contractor Field Management Represnetative before the audit to convey the purpose, scope, conduct and schedule of the audit, access to documents and other issues.

•
