Previous issue date: 2015-12-17 / A necessidade da ind?stria do petr?leo de garantir a seguran?a das instala??es, empregados e meio ambiente, sem esquecer a busca pela m?xima efici?ncia das suas instala??es, faz com que se busque atingir um alto n?vel de excel?ncia em todas as etapas de seus processos produtivos a fim de se obter a qualidade requerida do seu produto final. Conhecer a confiabilidade de um equipamento e o que esta representa para um sistema ? de fundamental import?ncia para a garantia da seguran?a operacional. A t?cnica de analise de confiabilidade vem sendo cada vez mais aplicada na ind?stria do petr?leo como ferramenta de predile??o de falhas e eventos indesej?veis que podem afetar a continuidade operacional. ? uma metodologia cientifica aplicada que envolve conhecimentos nas ?reas de Engenharia e Estat?stica para conhecer e ou analisar a performance de componentes, equipamentos ou sistemas, de forma a assegurar que estes executem sua fun??o, sem falhar, por um per?odo de tempo determinado e sob uma condi??o especifica. Os resultados das analises de confiabilidade auxiliam na tomada de decis?o acerca da melhor estrat?gia de manuten??o das plantas petroqu?micas. A an?lise de confiabilidade foi aplicada em um equipamento (moto-ventilador centr?fugo) entre o per?odo de 2010 a 2014 no Polo Industrial Petrobras de Guamar?, situado na zona rural do munic?pio de Guamar? no estado do Rio Grande do Norte, onde foram coletados dados de campo, analisado hist?rico do equipamento e observado o comportamento das falhas e seus impactos. Os dados obtidos foram processados em software comercial de confiabilidade. Os resultados obtidos foram comparados com uma pesquisa realizada junto aos especialistas da ?rea a fim de se obter a melhor estrat?gia de manuten??o para o sistema estudado. As an?lises foram satisfat?rias e comprovaram a efic?cia da aplica??o da metodologia, apontando possibilidades de ganhos relevantes e melhoria no plano de manuten??o dos equipamentos, bem como, aumento significativo da confiabilidade dos equipamentos analisados. / The need of the oil industry to ensure the safety of the facilities, employees and the
environment, not to mention the search for maximum efficiency of its facilities, makes it
seeks to achieve a high level of excellence in all stages of its production processes in order to
obtain the required quality of the final product. Know the reliability of equipment and what it
stands for a system is of fundamental importance for ensuring the operational safety. The
reliability analysis technique has been increasingly applied in the oil industry as fault
prediction tool and undesirable events that can affect business continuity. It is an applied
scientific methodology that involves knowledge in engineering and statistics to meet and or
analyze the performance of components, equipment and systems in order to ensure that they
perform their function without fail, for a period of time and under a specific condition. The
results of reliability analyzes help in making decisions about the best maintenance strategy of
petrochemical plants. Reliability analysis was applied on equipment (bike-centrifugal fan)
between the period 2010-2014 at the Polo Petrobras Guamar? Industrial, situated in rural
Guamar? municipality in the state of Rio Grande do Norte, where he collected data field,
analyzed historical equipment and observing the behavior of faults and their impacts. The data
were processed in commercial software reliability ReliaSoft BlockSim 9. The results were
compared with a study conducted by the experts in the field in order to get the best
maintenance strategy for the studied system. With the results obtained from the reliability
analysis tools was possible to determine the availability of the centrifugal motor-fan and what
will be its impact on the security of process units if it will fail. A new maintenance strategy
was established to improve the reliability, availability, maintainability and decreased
likelihood of Moto-Centrifugal Fan failures, it is a series of actions to promote the increased
system reliability and consequent increase in cycle life of the asset. Thus, this strategy sets out
preventive measures to reduce the probability of failure and mitigating aimed at minimizing
the consequences.
