Development of a Fault Tree Analysis (FTA) for Structural Integrity Assessment of Gas Pipelines: a Literature-Based Approach

Objectives: This study aims to develop a Fault Tree Analysis (FTA) model to assess the structural integrity of pipelines, addressing the critical vulnerabilities these systems face, such as corrosion, material defects, and damage from external sources. Theoretical Framework: The study is based on a systematic literature review and industry data, identifying significant failure modes such as ruptures and punctures, while also elucidating their underlying causes and potential consequences in the context of pipeline integrity management. Method: The research employs a literature review approach to compile and analyze existing information in order to construct a fault tree model that can be used for quantitative risk assessments. Results and Discussion: The primary outcome is the development of a model that not only identifies critical failure modes but also clarifies the interrelationships between them, thereby providing a more robust understanding of the failure mechanisms that affect pipeline safety. Research Implications: This work contributes to the management of gas transportation network integrity by offering a valuable tool for informed decision-making regarding the safety and sustainability of these systems. Originality/Value: The originality of this study lies in the development of a specific FTA model for pipeline failures involving product releases, addressing the growing need for effective methodologies to assess structural integrity and manage risks in these essential infrastructures.
