Development and implementation of predictive maintenance program to improve operational power generator availability of a vessel Perú navy-2016

Abstract

In this research work it has proposed to determine whether the implementation of a Plan predictive maintenance help to increase operational availability of the power generator of a ship, Peruvian Navy-2016, the sample selection 95% confidence and 5% personal significance was 72 specialty motorists for what interview technique, process multivoting, surveys, registers and Likert scale was applied. Currently power generators that have naval units do not have a current maintenance program,making a diagnosis in the engineering department he found a 90.17% operating availability of 2015 with a correlation coefficient of 0.4381 due to lack maintenance and supervision. As a result the power generator does not work efficiently and prevents increase operational availability. procedure was performed to identify the most frequent failures and by Pareto critical points resulting in direct problems with 50.84% and indirect 36.85%, then the matrix of criticality was applied resulting in the Pre-lubrication and oil cooler are in a critical state, oil analysis and vibration to the pre-lubricates was performed obtaining the CV (standard deviation / mean) of 15%, 8%, 13.1% at different points and Asymmetry of 2,142 and 2,295, contrasting the general hypothesis 95% confidence predictive maintenance improves operational availability of the power generator, these results contribute to extend the life of the engine and diagnose the evolution of failures improving operational availability of the power generator of a ship, Navy of Peru-2016.
