본 논문에서는 실습선과 함정의 광원으로 80 % 이상을 차지하는 백열등 및 형광등기구를 대체하기 위한 선박용LED 등기구의 경제성 분석에 관하여 기술하였다. 소비전력, 초기투자비용, 유지비용 및 유류비에 대한 절감률을 분석하였고, 탄소배출량과 손익분기점을 산출하였다. 실습선의 초기투자비용은 3.8배 상승하였지만, 5년간 유지비용은 51 % 절감되었다. 40 %, 50 % 및 60 %의 점등률에 따른 손익분기점은 각각 11개월, 9개월 및 7개월로 산출하였다. 함정의 초기투자비용은 3.5배 상승하였지만, 5년간 유지비용은 55 % 절감되었다. 40 %, 50 % 및 60 %의 점등률에 따른 손익분기점은각각 15개월, 12개월 및 10개월로 산출하였다. 또한 실습선과 함정의 탄소배출량은 각각 69 % 및 65 % 절감되었다. 이러한 결과를 통하여 실습선과 함정에 LED 등기구를 적용한다면, 50 % 이상의 유지비용 절약과 60 % 이상의 소비전력, 유류비 절감 및 탄소배출량이 감소될 것으로 판단된다.
Abstract
This paper dealt with the economic analysis on the application of shipboard LED (Light Emitting Diode) luminaires to replace incandescent and fluorescent lamps, which account for over 80 % of light source on a training or naval vessel. The rates of savings achieved in the power consumption, initial investment, maintenance cost, and fuel cost were analyzed. The break-even points and the CO2 emissions were also calculated. For the training vessel, the initial investment was increased by 3.8 times, while the maintenance cost over five years was reduced by 51 %. When 40 %, 50 %, and 60 % of luminaires were turned on, the calculated break-even points were 11 months, 9 months, and 7 months, respectively. On the other hand, the initial investment was increased by 3.5 times while the maintenance cost over five years was saved by 55 % for the naval vessel. The break-even points were calculated as 15 months, 12 months, and 10 months, respectively. Moreover, the CO2 emissions of the training and the naval vessels were reduced by 69 % and 65 %, respectively. From the results, it was revealed that the maintenance cost can be reduced by more than 50 %, and that the power consumption, fuel cost, and CO2 emissions can be reduced by more than 60 % if LED luminaires are used on two types of vessels.
