2 HSE Impact Assessment What is an HSEIA & Its Importance CONFIDENTIALHSE Impact Assessment What is an HSEIA & Its ImportanceSaturday, 01 April 2017An HSEIA is systematic approach to evaluating the potential effect of a project on health, safety and the environmentA living document that considers the full lifecycle of the project (FEED, EPC, Operations, Decommissioning & Abandonment)ADNOC Requires HSEIAs to be undertaken for all project phasesKey function is to identify, assess, mitigate to ALARP and monitor on a continuous basis all material risk that can adversely impact health, safety, and environmentResidual impacts and hazards managed by the operator’s HSE Management System (HSEMS)HSEIA and an Operators HSEMS are mutually exclusive….Abu Dhabi Gas Development Co.
3 A Lifecycle Approach to the HSEIA Process Introduction to the Approach CONFIDENTIALA Lifecycle Approach to the HSEIA Process Introduction to the ApproachSaturday, 01 April 2017A streamlined, risk-based and quality-focused methodology based on current industry best practice for HSE Case developmentA systematic and gated verification and review process that provides for the management of major accident hazards through the lifecycle of the Shah Gas Development (SGD) ProgrammeGreater emphasis is placed on HSE Critical Equipment and Systems (HSECES) integrity that provides significant safety and efficiency benefits to the end userDeveloped in close cooperation with the ADNOC EHS DivisionDemonstrates the safe systems of work and organisation required to effectively identify, manage and maintain risks to a tolerable and As Low As Reasonably Practicable (ALARP) levelBased on the detailed assessment of the proposed SGD activities and the outputs from HSEIA studies, management plans and proceduresAbu Dhabi Gas Development Co.
4 CONFIDENTIALA Lifecycle Approach to the HSEIA Process How it is Different from Traditional HSEIA ApproachesSaturday, 01 April 2017The Al Hosn Gas HSEIA approach is a departure from traditional HSEIAs process in the following ways:Process based method compared to the traditional prescriptive methodology of HSEIA report developmentIs overarching and not limited to providing a ‘snap-shot’ in time of HSE risk i.e. lifecycle philosophySystematic and gated verification and review process provide tangible barriers from allowing the development to proceed to the next stage until a strategy to manage HSE risks to ALARP can be put in placeReduces unnecessary duplication of HSE studies/reviews; andReduces the turnaround time for obtaining approvals from ADNOC EHS Division.Inter-linkages between quality management and procurement thus effectively integrating supply chain logistics in the lifecycle and improving operational efficiencyAbu Dhabi Gas Development Co.

Identify all the design codes for equipment and systems.1.2 During this stage we must also ensure that we have management of change system in place such that a change in design requirements goes through the proper review, approval and documentation process.Abu Dhabi Gas Development Co.

12 SGD Phase II – Drilling, Well Testing & Cleanup Phase Element CONFIDENTIALSaturday, 01 April 2017SGD Phase II – Drilling, Well Testing & Cleanup Phase ElementProcurement, Inspection & Testing55.1Purchase InformationHSECES Design Performance Standards Operating Envelope Criteria5.2Verification of Purchased ProductsHSECES inspection and test plansIndependent Verification Process for HSECES5.3Inspection & TestingInspection and testing plans prior to operationThis is also a critical stage of the HSECES integrity lifecycle. Through the detail design once equipment and systems have been identified the next step is their procurement. Every Critical equipment & system must have design performance standards that are aligned with design details undertaken by Drilling & Sub-surface technical teams during detail design phase.Equipment must be verified and inspected at site and by third party verification process. In addition, once the equipment arrives at the rig site and before it can be in colloquial parlance “turned on” it has to be testing from a function point of view.It is also important in this stage to have change control procedures. A good example, is changing the dimensions, or locations of storage warehouse to better fit equipment or chemicals, an appropriate risk must be undertaken as part of the change control procedures.The main point to make here is to capture all the risk associated with the procurement, inspection and testing of HSECES.5.4Inspection & Disposition ReportsVerification of inspection reportsThird Party Inspection monitoringChange Control proceduresAbu Dhabi Gas Development Co.

16 A Lifecycle Approach to the HSEIA Process The Benefits CONFIDENTIALA Lifecycle Approach to the HSEIA Process The BenefitsSaturday, 01 April 2017The HSEIA approach provides tangible performance enhancement benefits in the following ways:A greater focus on MAHs and HSECES integrity thus significantly reducing the overall risk picture;Greater flexibility for managing HSEIA process associated with multi-package/multi-rig operations thus providing optimum efficiencyMinimizing overall lifecycle costs through procurement of HSECES against approved performance standards i.e., QA/QC of HSECES from day oneReduction of turnaround in ADNOC/SPC approval process i.e., SGD Program HSEIA Phase II approvals have been achieved approximately 14 days from submittalThe approach is fully integrated with ADNOC & COMPANY HSEMSThe iterative and evergreen nature of the approach provides the opportunity for continuous improvementAbu Dhabi Gas Development Co.
