Electrical design for efficiency: technical and operational measures for optimizing the use of electrical power on ships

There is currently a growing concern in the shipping industry about energy consumption and environmental impacts. According to International Maritime Organization's (IMO) efficiency guidelines, today's ships must have an management plan reduce CO2 emission other pollutants. In this article, bibliographic review of methodologies for optimization on carried out, starting from identification sources losses, implementation technical operational measures that contribute their improvement, making qualitative evaluation identified methodologies. Sources losses associated with equipment auxiliary systems are analyzed, as well opportunities improvement use electrical through intelligent systems, high motors, lighting. The described above demonstrate importance early stages ship's design, monitoring during its life cycle, improve board.
