An integrated Pipeline Integrity Management System (PIMS) environment enables practices that result in more efficient data maintenance and information reliability while providing consistent application of integrity procedures including risk assessment and risk management.Bringing an integrated PIMS software solution online can be a daunting task.Todays pipeline operators rely on a growing number of tools to manage and communicate day-to-day activities as well as near-and long-term planning for asset maintenance and integrity assurance.These tools tend to evolve and many times contain redundant, if not conflicting, data that can lead to confusion between groups and decisions based on incomplete or outdated information.Current risk assessment practice in pipeline integrity management commonly uses semi-quantitative index-based or model-based methodologies.These approaches have been found to be very flexible and provide useful results for identifying high-risk areas and for prioritizing physical integrity assessments.However, as pipeline operators progressively adopt an operating strategy of continual risk reduction with a view to minimizing total expenditures within safety, environmental and reliability constraints, the need for quantitative assessments of risk levels on a system-wide basis is becoming more and more evident.This paper describes the role of risk assessment and risk management within pipeline integrity management and how it is represented by the regulatory environment.A pipeline risk assessment methodology that estimates quantitative risk on a system-wide basis and can be tailored to suit the operators data availability, data quality and analysis needs is described.Our experiences and challenges of implementing PIMS software including risk assessment tools are also discussed in the paper.
