Abstract(s)
Os ativos físicos são o essencial de uma empresa industrial. Para manter
esses equipamentos em bom estado tem de ser feita uma gestão rigorosa e
planeada, ou seja, é preciso conhecer bem esses ativos, a sua importância e
criticidade na operação da fábrica e ter uma manutenção preventiva atualizada
e eficaz
O presente projeto de tese, no âmbito do Mestrado em Engenharia
Mecânica e Gestão Industrial (MEMGI) teve como objetivos a aplicação de uma
análise de risco e o processo RCM (Manutenção centrada na fiabilidade) numa
Central Termoelétrica de Biomassa.
Em primeiro lugar, foi feita uma listagem e organização dos ativos em
sectores/áreas para, seguidamente, fazer uma análise de risco usando os
métodos da entrevista estruturada e das tabelas de risco. Com esta análise de
risco foi obtida a informação sobre os equipamentos e quais os ativos mais
críticos e com prioridade no estudo da fiabilidade e manutenção.
A etapa seguinte foi a aplicação do processo de manutenção centrada na
fiabilidade (RCM) ao equipamento que, do estudo anterior, foi considerado mais
crítico para a central de Biomassa. Este é um processo muito eficaz e rigoroso
na definição de planos e tarefas de manutenção de equipamentos críticos e de
grande valor.
Os resultados da aplicação do processo RCM permitiram, por um lado,
propor à empresa a aplicação de um novo plano de manutenção (que será mais
eficaz e que permitirá evitar paragens não programadas, maior fiabilidade e
consequentemente maior disponibilidade) e, por outro lado, permitiram também
ter um histórico mais rigoroso e consequentemente mais conhecimento sobre o
equipamento.
ABSTRACT: Physical assets are the essentials of an industrial company. In order to keep this equipment in good condition, strict and planned management must be carried out, that is, it is necessary to know these assets well, their importance and criticality in the factory's operation and have an up-to-date and effective preventive maintenance This thesis project, within the scope of the MSc in EMGI, aimed to apply a risk analysis and the RCM process (Reliability Centered Maintenance) in a biomass power plant. Firstly, a listing of the organization of assets into sectors/areas was made, followed by a risk analysis using the methods of structured interview and risk tables. With this risk analysis, information was obtained about the equipment and which active assets are most mandatory and with priority in the study of reliability and maintenance. The next step was the application of the Reliability Centered Maintenance (RCM) process without equipment, which from the previous study, was considered more critical for the Biomass plant. This is a very effective and rigorous method, good at defining plans and maintenance tasks for high-value and mandatory equipment. The results of the application of the process allowed, on the one hand, to propose to the company the application of a new maintenance plan, which will be more effective and will allow to avoid unscheduled stops, greater reliability, and consequently greater availability and, on the other hand, they also allowed, a more rigorous history and, consequently, more knowledge about the equipment.
