18CONCEPT SELECTION REPORTThe Concept Selection report forms the basis for the engineering activities in the Define phase. 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:
The HSE content of the Concept Selection report shall include: 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. Large and complex projects will typically require a separate ALARP demonstration report to meet the above requirements. 18.1DCAF Deliverables for Identify, Assess and Select PhasesIndividual components of the Concept Select Report are required deliverables under the Discipline Controls and Assurance Framework (DCAF). The Concept Select Report is itself a required DCAF deliverable. The full list of HSE DCAF deliverables for the Select phase which should be produced and signed off individually by the relevant competent person/Technical Authority is given below. Ensure DCAF is consulted for latest version of specified deliverables and the Discipline Authority Manual (TAs): ALARP Demonstration Report HEMP Findings and Close out Report HAZID Report Concept Risk Assessment Report (i.e. the Qualitative Risk Assessment (QRA)) Preliminary Hazard and Effects Register Greenhouse Gas (GHG) and Energy Efficiency Report Fire and Explosion Assessment Sustainable Development Strategy Regulatory Compliance and Permitting Plan HSSE and SP (Social Policy) Plan HSSE and SP Philosophy Document The Concept Select Report shall contain summaries and/or references to all the above documents. 19DESIGN HSE CASE REQUIREMENTSThe Concept Select Report is the starting point for developing the Design HSE Case as it describes the Identify & Assess and Select phases in detail. The Design HSE Case focuses on the chosen concept through the Define and Execute phases and is a DCAF Deliverable. It must be signed off by the project management prior to VAR4 (for FEED) and prior to the Pre-Start Up Audit for HSE Cases at the end of detailed design. The final design HSE Case is used as part of the ALARP demonstration in the Operations HSE Case. 19.1Basic RequirementsThe Design HSE Case: Is required to demonstrate that there has been a systematic application of HEMP during the Define and Execute phases and that the risk has been actively and systematically reduced to ALARP shall incorporate any design changes made during the Define and Execute phases that impact severity 5 or high level hazards and updating the risk tolerability and ALARP demonstrations shall incorporate a full list of safety critical elements (SCEs) with relevant performance standards (SCEs shall be identified in accordance with EP2009-9009) shall be signed off by the Project Manager shall be used to develop the Operations HSE Case prior to the pre-start up audit (PSUA) and subsequent operate phase 19.2FormatThe Design HSE Case shall be based on the following structure: Contents
Part 1 Introduction Part 2 Concept Select Report Summary Part 3 Design Basis & Facilities Description Part 4 HEMP and major accident hazard (MAH) assessment (including ALARP Demonstration, safety critical elements (SCE) and Bow-ties) Part 5 Improvement (Remedial Action Plan)
19.2.1ContentsThis part shall contain: Document authorisation, identification of the HSE Case Owner, HSE Case Custodian, and HSE Case Administrator and their responsibilities Version control, showing the scope of each revision Signed off Statement of Fitness for the Design HSE Case by the HSE Case Owner (usually the Project Manager). The Statement of Fitness is signed on the understanding that all remedial actions outlined in Part 5 of the Design HSE Case are, or will be, closed out effectively by their action target dates.
Describe the scope of the Design HSE Case State the relationship with the HSE Management System (HSE-MS) Manual, CP-122 Provide a summary of the change control process applied trhough the various stages of the project. Include a project summary
A detailed description of the chosen concept, including site selection, plant layout, material selection, etc., including a project overview to show boundaries of the HSE Case A description of all of the safety critical elements and any other safety systems provided. A list of all DEPs, codes, standards and specifications used in the design A summary description and reference to, the Operations and HSSE Philosophies, including manning strategies and philosophies A list of identified HSE risks from the Project Risk Register. A list of the MAH associated with the facilities A Variance Register, or reference to it, providing justification why the engineering standards or specifications for the project deviate from applicable Design Engineering practices (DEP) A list of all safety critical elements (SCE) - defined as hardware barriers on the bow-ties (in accordance with EP2009-9009)
A Hazard and Effects Register containing details of all severity 5 and high risk hazards and an assessment of each hazard including the key assumptions (assessed using the PDO risk assessment matrix in Figure 2 ) Bow-Tie diagrams for severity 5 and high risk hazards, with barriers categorised as inherent safety, safety critical element (SCE), procedural control and remedial action/shortfall ALARP Demonstration, to state how the qualitative Bow-Tie assessment has been reviewed to ensure all applicable measures to reduce risk to tolerable and ALARP have been assessed and implemented Details of utilised HSE Risk Tolerability, Acceptance Criteria, and ALARP Framework Summaries of the philosophies and measures implemented during the Design phase to reduce residual risks to ALARP Summary of HEMP studies undertaken since the Concept Select Report, e.g. Hazard Identification studies (HAZID), Hazard and Operability studies (HAZOP), Instrumented Protective Function (IPF), plant layout study, Quantified Risk Assessment (QRA), Health Risk Assessment (HRA) Human Factors Engineering (HFE), consequence modelling, EER Assessment, etc. A summary of practical risk reduction measures and their implementation unless demonstrated not reasonably practicable. These may be represented on ALARP Worksheets. Any issues that may have an impact on the risk profile and so need to be addressed during the Operate phase See Sections 9, 10 and 14 for more details on undertaking HEMP, Bow- Ties and ALARP Demonstrations, respectively. 19.2.6Part 5 Improvement (Action Plan)Part 5 shall contain an action plan that is SMART (specific, measurable, agreed, realistic and timely) which lists all the actions to be carried forward to, and dealt with, in the Operations HSE Case. All remedial action items arising from review and update of the HSE Case shall be accepted by the appropriate action parties and approved by the HSE Case Custodian (Delivery Team Leader). Following approval, the action items shall then be entered into the PDO action tracking system to be formally tracked and closed out. At the time of issue of this Specification, the Fountain Incident Management (FIM) system is used for tracking actions from HSE Cases. See Section 15 for more details on continuous improvement.
