Eficiência energética em sistema de embarcações: análise da eficiência energética em lâmpadas do Navio Patrulha Guarujá P-49

Abstract

In this study, an in-depth survey of the energy efficiency of lamps on board the Patrulha Guarujá P-49 was carried out, seeking significant knowledge to improve its energy performance and, consequently, contribute to more efficient and sustainable naval operations. The methodology involved a quantitative analysis of the consumption, costs and environmental impacts of the lamps used, followed by the application of economic metrics, such as Payback and Net Present Value, with a Minimum Attractiveness Rate of 20%. The results revealed the financial viability of replacing lamps with more efficient alternatives, generating energy savings and operational costs, while reducing environmental impacts. The conclusion highlights the importance of considering not only energy efficiency, but also financial and environmental aspects when making decisions about improvements to the vessel's lighting system, with potential for application on other vessels in the Brazilian and international naval fleet.
