A implementação da manutenção preditiva na MB: uma proposta para o aumento da disponibilidade e confiabilidade dos meios

Abstract

The main objective of this research is to verify the applicability of predictive maintenance in the Brazilian Navy as a way to increase reliability and availability at an adequate cost-benefit ratio, so that it could become a viable solution for ships in operation and for new acquisitions. Descriptive research was carried out with the objective of finding arguments in the existing literature that could provide support to the benefits of using predictive maintenance. In the development of this thesis, predictive and corrective maintenance were compared, as they are the most performed in the Brazilian Navy. Although the use of predictive maintenance is foreseen in Navy publications, it was observed that it was not applied or used modestly, which accelerated the downgrade of asset performance contributing to the current critical situation that is still worsened by budget constraints and the advanced age of ships. The higher costs to implement predictive maintenance will be offset by the increase in reliability, availability, and maintainability and throughout the defense system lifecycle it becomes cheaper than other types of maintenance. Predictive maintenance must be a protagonist in a new maintenance mentality where corrective and preventive interventions will become more effective
