HSE Impact Assessment
What is an HSEIA & Its Importance
• An HSEIA is systematic approach to evaluating the potential effect of a project
on health, safety and the environment
• A living document that considers the full lifecycle of the project (FEED, EPC,
Operations, Decommissioning & Abandonment)
• ADNOC Requires HSEIAs to be undertaken for all project phases
• Key function is to identify, assess, mitigate to ALARP and monitor on a
continuous basis all material risk that can adversely impact health, safety, and
environment
• Residual impacts and hazards managed by the operator’s HSE ManagementSystem (HSEMS)

A Lifecycle Approach to the HSEIA Process
Introduction to the Approach
• A streamlined, risk-based and quality-focused methodology based on current
industry best practice for HSE Case development• A 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) Programme
• Greater emphasis is placed on HSE Critical Equipment and Systems (HSECES)
integrity that provides significant safety and efficiency benefits to the end user• Developed in close cooperation with the ADNOC EHS Division
• Demonstrates 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) level
• Based on the detailed assessment of the proposed SGD activities and the outputsfrom HSEIA studies, management plans and procedures

A Lifecycle Approach to the HSEIA Process
How it is Different from Traditional HSEIA Approaches
The 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 development
• Is overarching and not limited to providing a ‘snap-shot’ in time of HSE risk i.e.
lifecycle philosophy
• Systematic and gated verification and review process provide tangible barriersfrom allowing the development to proceed to the next stage until a strategy to
manage HSE risks to ALARP can be put in place
• Reduces unnecessary duplication of HSE studies/reviews; and
• Reduces 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
efficiency

• Mitigate risk to ALARP
• Provide control measures and monitoring

A Lifecycle Approach to the HSEIA Process
The Benefits
• The 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 efficiency
• Minimizing overall lifecycle costs through procurement of HSECES againstapproved performance standards i.e., QA/QC of HSECES from day one
• Reduction of turnaround in ADNOC/SPC approval process i.e., SGD Program
HSEIA Phase II approvals have been achieved approximately 14 days from
submittal
• The approach is fully integrated with ADNOC & COMPANY HSEMS
• The iterative and evergreen nature of the approach provides the opportunity for
continuous improvement
