Abstract

As the seriousness of global environment pollution is gaining increasing public attention, research into greenhouse gas emissions of ships is being carried out globally. At a domestic level, however, in a number of significant fields such research has not been conducted to date. This study examined countermeasures for the reduction of $CO_2$ emission in the fields of electronic control engines, trim optimization, propeller polishing, hull cleaning, and anti-fouling paint using an actual sea-going vessel. Selected countermeasures were applied during sea trials of the ship and the effect of specific fuel oil consumption analyzed. It was found that each countermeasure resulted in a decrease of fuel consumption of 1~5%. The energy efficiency operational indicator (EEOI) was calculated and found to also be improved by 1~5%. Further research into the EEOI of domestic shipping is planned to enhance conformance with international environmental regulations and improve global competitiveness.

지구온난화에 대한 심각성이 대두되면서 선박부문의 온실가스 배출에 관한 연구가 전 세계적으로 활발하게 진행되고 있다. 이에 반하여 국내 연구 수준은 기초에 그치고 있다. 본 논문에서는 선박으로부터 배출되는 이산화탄소의 여러가지 저감대책 중에서 운항손실과 투자비용을 최소화하면서 수행할 수 있는 방법으로 전자제어엔진 사용, 트림 최적화, 프로펠러 연마 및 친환경 방오도료의 사용을 선정하였다. 선정된 저감대책들을 운항실습선에 적용하여 시험 운항을 실시하였고 연료소비율에 미치는 영향을 분석하였다. 그 결과, 각 대책들은 약 1~5%의 연료소비율 저감 효과가 있었고 이를 에너지효율운항지수 산출에 적용하면 약 1~5%를 감소시키는 것을 알 수 있었다. 향후 국제적 환경규제를 제정할 때 우리나라에게 유리하도록 대응하기 위해서는 에너지효율운항지수에 대한 연구에도 지속적인 노력이 필요하다고 사료된다.
