A Manutenção de equipamentos e sistemas nos meios navais da Marinha: atualização da abordagem da manutenção com uso de técnicas de manutenção preventiva preditiva, visando minimizar custos e maximizar disponibilização e confiabilidade dos meios

Abstract

Increased competitiveness in recent decades has become vital to the survival of many companies, which led, among other things, a relentless pursuit of reducing costs and maximizing the availability and reliability of machinery and systems related to production. As a consequence, maintenance systems have evolved to meet these improved requirements. An update to Brazilian Navy (BN) maintenance systems is proposed, by means of the implementation of condition-based maintenance techniques applied to BN vessels, which is expected to provide increased operation times with reduced ownership costs. To achieve these purposes, maintenance systems key concepts evolution is described, including the condition-base maintenance. Therefore, industrial and Navies maintenance systems employed are presented, with especial attention to periodic main tenance system witch is currently used within BN. A brief analysis is made to understand the main reasons which led the BN to fail in the implementation of the predictive maintenance in the past. Then, it finally made a proposal to update the maintenance approach in the BN, linking both the logistical aspects such as strategic and financial, to implement definitely a policy of effective and systematic predictive maintenance, in addition to periodic maintenance currently employed.
