Post Conference Workshop C (Fri 31 July 2009)
Risk Assessment and Integrity Management of Pipelines in High Consequence Areas (HCAs)
9:00 – 12:00
High consequence areas, commonly called HCAs, are those locations where a pipeline spill might have significant adverse impacts to population, environment, or commercial navigation. The physical location of some HCAs will change over time due to topographical transformation, and change in environment. Hence, pipeline system integrity and integrity management programs should be evaluated on a regular basis. Preparing and conducting a risk assessment are the key elements in managing pipeline system integrity. This workshop will address various stages of risk assessment, and in particular the quantitative risk assessments (QRA) in identified HCAs.
Issues / Topics covered in the workshop
- Elements of Integrity Management System
- Types of Risk Assessment
- Definition and Identification of HCAs
- Risk Assessment of Pipelines Segments
- Mitigation Methods to reduce the high risk of HCAs
Outcomes of the workshop
At the end of the workshop participants shall be able to:
- Understand the role of various elements in integrity management system
- Understand the differences between qualitative, semi-qualitative and quantitative risk assessments methodologies and their applications
- Gain the knowledge on the impact of High Consequence Areas (HCAs) on pipeline integrity management approach
Workshop Leader:
Dr. Mabruk Issa
Head of Abu Dhabi Refinery Inspection
TAKREER
Dr Mabruk has 29 years experience both in upstream and downstream processes. He has produced more than 100 corrosion investigation reports and published several papers on stainless steel corrosion. He obtained both his M.Sc. and Ph.D. from the University of Manchester Corrosion Engineering Research Centre. He is a professional member of the institute of corrosion (UK), and one of the founders of corrosion engineering society in Libya. He is also very active in the field of asset integrity management, pioneered the dynamic approach for refinery integrity management system, and presented several papers on this subject.
Post Conference Workshop D (Fri 31 July 2009)
Rehabilitation of ADGAS CP- System to Protect the Integrity Underground Structures
13:30 – 16:30
Pipe lines buried in the earth represent a challenge and can seriously affect plant reliability and profitability. The response of carbon steel to soil corrosion depends primarily on the nature of the soil and certain other environmental factors, such as the presence of moisture and oxygen, and etc. These factors can lead to extreme variations in the rate of attack. However, if adequate cathodic protection is available to protect any exposed bare metal due to paint / or wrapping deterioration this type of attack becomes unlikely. This workshop will provide participants the overview of latest applicable cathodic protection in pipeline defect assessments methodologies and repair techniques available in the industry.
Issues / Topics covered in the workshop
- Overview of codes and standards
- Cathodic protection principle
- Stray currents which were detected on the concrete foundations reinforced steel bar causing concrete delamination.
- Shielded areas for the underground structure causing external corrosion.
- Lack of sufficient CP monitoring points leads to un-clear picture of the distribution potential for the underground structure
Outcomes of the workshop
At the end of the workshop, participants would be able to:
- Gain the knowledge on applicable codes and standards for pipeline.
- Gain the knowledge of stray currents detection.
- Gain the knowledge of shielded areas for the underground structure.
- Gain the knowledge about the limitations of insufficient CP monitoring points on the system integrity.
