A presente dissertação foi desenvolvida no âmbito de conclusão do curso de Mestrado de Engenharia Mecânica – Perfil de Manutenção e Produção. Sob uma orientação bem definida, a principal motivação deste trabalho consistiu na elaboração de uma Análise de Riscos em Sistemas de Transporte de Hidrogénio, com especial foco no transporte de hidrogénio através de pipelines. Numa primeira fase foram abordados métodos de produção, tipos de armazenamento e transporte de hidrogénio, dando especial importância aos pipelines, como estes são projetados, quais os componentes constituintes, etapas de construção, fase de operação e manutenção e aspetos relacionados com a segurança. Seguidamente foi apresentado um estudo exemplificativo que visa avaliar a quantidade ótima de hidrogénio injetável numa rede existente de pipelines de hidrogénio, terminando com a apresentação dos maiores riscos e desafios no transporte de hidrogénio em pipelines existentes. Posteriormente, foi abordado o tema do risco de uma forma genérica, seguindo as normas ISO 31000 e ISO 31010, com o objetivo de identificar as técnicas e ferramentas existentes para a sua aplicação de modo a mitigar os riscos inerentes a um sistema e/ou processos. Por fim foi elaborada uma FMEA (Failure Mode and Effects Analysis) aplicada a pipelines de hidrogénio, com o principal objetivo de identificar modos de falha, causas e consequências.
Abstract This dissertation was developed within the scope of completion of the Master’s degree in Mechanical Engineering - Maintenance and Production Profile. Under a well defined orientation, the main motivation of this work was to develop a Risk Analysis for Hydrogen Transport Systems, with special focus on the transport of hydrogen through pipelines. In a first phase, production methods, types of hydrogen storage and transportation were addressed, giving special importance to the pipelines, how they are designed, which components, construction stages, operation and maintenance phases and safety related aspects. Then, an illustrative study was presented that aims to evaluate the optimal amount of hydrogen injectable in an existing network of hydrogen pipelines, ending with the presentation of the major risks and challenges in the transport of hydrogen in existing pipelines. Subsequently, the risk issue was addressed in a generic way, following the ISO 31000 and ISO 31010 standards, with the objective of identifying existing techniques and tools for their application to mitigate the risks inherent to a system and/ or processes. Finally, a FMEA (Failure Mode and Effects Analysis) was developed applied to hydrogen pipelines, with the main objective of identifying failure modes, causes and consequences.
