0. Introduction to the HRA report
The Health Risk Assessment (HRA) report is used by PDO to process and store health
related information.
The report starts with a description of the scope of the HRA and the persons involved in
sections 1 and 2. The remedial actions from the HRA are presented in report section 3, and
are sorted by priority. Section 4 provides information from the detailed appraisals. The focus
here is on High and Medium RAM rated risks. Section 5 lists the status of the Low RAM rated
risks that were reviewed during the HRA. Section 6 provides an overview of generally
applicable controls and recovery measures. The report concludes with definitions and a
diagram of the RAM risk matrix in appendices 1 and 2. Appendix 3 contains an overview of
the detailed risk appraisals and their page numbers.
1. HRA Scope
PDO has installed green field surface facilities, both on-plot and off-plot, to enable production from the redeveloped Ghaba North field. Figure 1: Ghaba North Overall Process Schematic
The Ghaba North field is situated approximately 25 km to the North-East of the Qarn Alam field and is part of the Central Oman (Qarn Alam) operating area. Ghaba North – Off Plot Shuaiba In Shuaiba field there are new 18 gas lifted producer wells, 4 Gas Injection Wells and additional 4 future gas lifted producer wells, (provision only). Haushi In Haushi field there are 2 new, and 5 existing ESP lifted producers with provision for an additional 2 future wells. The production from the existing wells will be re routed to the new production facilities. The new Ghaba North station facilities receive produced fluids from Ghaba North Haushi, (sweet) and Ghaba North Shuaiba, (sour) reservoirs. In addition, produced fluids from QAM Haushi and Shuaiba are routed to the common bulk header, (down-stream of the MSVs) in the new station. In future, Barakat Haushi, (sweet) field will be developed and the produced fluids will be routed to the new Ghaba North station. On-Plot

Appendix 1: Definitions Acute Health Effect Health Effect that occurs immediately or a short time (seconds to hours) following exposure, such as heat stroke, chemical burns and asphyxiation. Agent See Hazard ALARP - As Low As Reasonably Applicable The point at which the cost (in time, money and effort) of further Risk reduction is grossly disproportionate to the Risk reduction achieved. Barrier A Risk Control or a Recovery Measure. Barriers provide the means of preventing an Event or Incident, or of mitigating the Consequences. A Barrier can be an item of equipment or a human intervention, and can also be a Control on an Escalation Factor. Chronic Health Effect Health Effect that occurs gradually over a long period of time (months or years), generally following repeated and prolonged exposure. In specific cases a short term exposure may result in a chronic health effect. Consequence An Effect on people, assets, the environment or reputation as a result of a Hazard being released. Control A means of preventing an Incident. Controls can be engineering, procedural or behavioral. Critical Activity An activity necessary for the development, implementation or maintenance of a Barrier established for managing Hazards with RAM red Risks. Effect The Consequence of the release of a Hazard. Escalation Factor A situation, condition or circumstance that may lead to the partial or full failure of a Barrier. Event An Incident that occurs when a Hazard is released. Exposure Limit The airborne concentration of chemical agents and levels of physical agents to which nearly all workers may be repeatedly exposed day after day without adverse Effect. Exposure Rating The chance of over-exposure to a health hazard when compared against agreed control standards. The exposure rating is evaluated as Very Low, Low, Medium or High. Hazard An agent with the potential to cause harm to people, damage to Assets, or an Impact on the environment or reputation. Health Hazard A factor of a physical, chemical, biological, ergonomic or psychological nature with the potential to cause harm to the health of people. HRA - Health Risk Assessment
Page 41 of 43
Printed copies of this document should be treated as information of temporary value and destroyed after use Printed: 03/12/2018
A process of identifying, evaluating, controlling and managing Health Risks, associated with work to prevent acute and chronic health Effects. Incident An unplanned Event or chain of Events that has, or could have, resulted in injury or illness or damage to Assets, the environment or reputation. Likelihood The probability that a specified Consequence will happen. OEL – Occupational Exposure Limit The airborne concentration of chemical agents and levels of physical agents to which nearly all workers may be repeatedly exposed day after day without adverse effect. RAM - Risk Assessment Matrix A tool used to assess the Consequences and Risks of Hazards to HSSE. The results are referred to as a RAM Severity rating and a RAM Risk rating. Recovery Measure A Barrier that reduces the Consequences of the release of a Hazard as a result of an Incident. Recovery Measures can be engineering, procedural or behavioral measures. Remedial Action Plan RAP - A Plan to implement corrective action items. Risk The combination of the Consequence of a specific Hazard being released and the Likelihood of it happening. Risk Assessment The process of identifying the Consequences of the Worst Case Credible Scenario arising from the release of a Hazard, and estimating the Likelihood of that scenario. Severity A level of Consequence on the RAM on a scale of 0 to 5. TBD To be determined.
