As the seriousness of the global environment pollution is gaining our attention recently, researches on application of greenhouse gas emission of ship are being carried globally. However domestic study on greenhouse gas emission from ship was not carried out in various fields. In this study, quantitative data which was presented by greenhouse gas emission of training ship HANBADA and greenhouse gas emission was cal-culated by Tier 1 method based on total fuel consumption and amount of shore power. Actual voyage data for 1year in 2012 was used to analysis the greenhouse gas emission. This study showed how many weight of gases were exhausted per 1 gross tonnage and per 1trainee in the training ship. There is a need of further re-search to reduce pollutant and to respond to international environment regulation consistently. Keywords: Environment pollution, Greenhouse gas, Tier 1, Fuel consumption, Shore electricity 1. 서 론 기후변화에 관한 정부간 협의체(IPCC)는 제 4차 보고서 [1] 를 통해서 21세기 기후변화의 가속화 전망을 제시하고 있으며, 현재와 같이 지속적으로 화석연료를 사용한다면 21세기 말까지 지구평균기온이 2.4∼6.4℃ 상승하고, 해수면은 26~60cm 상승할 것으로 전망하고 있다

Many researches on green ship with increasing on economics, efficiency and convenience have been carried out consistently. One of them is development of diesel engines with electronic control. While small duty one for automobiles had been adopted mainly already, disseminating heavy duty one for ships has trouble due to safety and reliability. In order to solve these problem in this study, performance of electronic control and cam type engine installed in parallel on training ship HANBADA of korea maritime university was analyzed and compared. It is certain that specific fuel oil consumption of the electronic control type is lower than cam type and excellent at lower engine load, especially. And the electronic control type shows more effective characteristic at sea trial on specific fuel oil consumption.

Many researches have been carried out consistently for the green ship owing to its economic increasement, efficiency and convenience. One of them is an electronic controlled marine diesel engine. However, we are suffered from dissemination of above engine, due to its anxiety about safety and reliability. In order to solve these problems in this study, emission characteristics test of main propulsive two-stroke diesel engine, equipped both electronic control and cam drive fuel injection systems, has been performed and evaluated under the various load conditions. From the test results, we have confirmed that exhaust gas emission characteristics of the electronic control system is similar to the cam drive system in eco-mode operation, but NOx in emission mode has been decreased 100ppm or more in full load condition. HC emission from the electronic control system is decreased 10~20ppm at 50% load, and 35~40ppm at 25% load in comparison to cam drive system. In fuel consumption, it is considered that 7g/kWh is decreased than the value of cam drive system at 700bar of injection pressure, which is 200bar higher than cam drive system.

In order to judge that non-esterified soybean oil could be used on diesel engine with electronic control of fuel injection system, The test of combustion performance using only gas oil, gas oil blended with esterified bio-diesel oil 5% and non-esterified soybean oil 5% were carried out. It is noticed that most performances of gas oil blended with esterified bio-diesel oil 5% and non-esterified 5% have similar characteristics but non-esterified bio-diesel oil 5% emitted smaller NOx, resulting from fuel NO.

Every ports is making great efforts to get competitiveness. It is progressing for the research on port model of new concept that connect port-related business to be developed from base running simple cargo processing to universal port that has economical efficiency and competitiveness, This research shows development way of Busan port that connect ship-repair industry which is port-related business. Development way is especially handled link between port and ship-repair industry field activation of high value-added ship as LNG etc.
