Política de manutenção de meios navais

Abstract

This paper aims to optimize the major overhaul of diesel engines applied in Brazilian Navy ships. An exploratory and applied research has been conducted in order to identify theoretical references, to analyze the interdependence of spare parts supply with the engines logistic maintenance function and to analyze and compare different possibilities of engine`s major overhaul contracts. The engine`s maintenance in Brazilian Navy must obey a Planned Maintenance System issued by the Material Sector. The General Maintenance Program identifies, for each year, the navy ships that will be repaired and the kind of maintenance that they will be subjected. The spare parts supply rooutine provides for scheduled engines overhaul established by the Operational Sector, provides the items and components that will be used in the engines maintenance. There is a problem, currently, that is the existence of a restrained demand of engine overhauls and delay to perform the ships maintenance on time due to lack of spares. The concept of operational availability and maintenance downtime are relevant to optmize the navy ships maintenance program.
