7WHAT 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: 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 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 Air Operations; the content shall meet the requirements of EP 2005-0263 Air Transportation Standard and this HSE Case Specification 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 ) 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: 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. 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. 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. 7.1Asset/Facility HSE Cases at different ORP phasesThe 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 . The Identify & Assess; Select; Define; Execute and Operate phases are discussed in the following sections. 
Figure 3 : 5 stages and applicable HSE Cases 7.1.1Identify and AssessThis 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.
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). 7.1.3DefineThe 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. 7.1.4ExecuteThe 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. 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. 7.1.5OperateThe 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).
