Abstract

The estimation of necessary power which determine the generator's capacity is based on the capacity of the equipped electric apparatuses to be equipped during the planning stage. The increase of electric power consumption caused by increase of electric apparatuses and the increase in specific fuel consumption caused by deterioration in performance of the engines are observed as years go by.<BR>Investigations were conducted to analyze the age deterioration of electric power equipments by experiment based on the vessel's log books.<BR>The following conclusions were obtained.<BR>1) Increase of electric power consumption is 2.2KW per year, with almost no recognizable difference in electric power between normal runnig service and in-port service.<BR>2) The deterioration in performance of engines by exhaust gas temperature, expressed in load [KW], is 0.8KW per year.<BR>3) The Age Deterioration of Electric Power Equipments estimated in electric power [KW], is 3.0KW per year. This value is equivalent to 1% of the main generator's capacity.
