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 Management
System (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 outputs
from 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 barriers
from 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

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 multipackage/multi-rig operations thus providing optimum efficiency
• Minimizing overall lifecycle costs through procurement of HSECES against
approved 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
