초록

18,000 TEU 급 대형 컨테이너 운반선의 그린쉽 설계에 관한 연구로 기본설계와 에너지 효율 향상 관점에서 선형 최적화 과정을 4단계로 나누어 체계적으로 연구를 수행하였다. 첫째, 환경적 측면 및 법규 등을 고려하여 대형 컨테이너 운반선의 경제성 평가를 수행하였다. 둘째, 기본설계 및 성능 관점에서 단축선형과 쌍축선형의 특징을 조사하였다. 셋째, 설계 흘수 및 속도에서 저항과 추진 성능을 향상시키기 위한 단축 및 쌍축선의 선형 최적화를 CFD와 모형시험을 통해 수행하였으며 최적 선형의 성능 향상을 확인하였다. 마지막으로 실제 운항조건을 고려한 추정된 운항 흘수와 속도에서 CFD를 통해 최적화된 최종 선형을 제시하였다. 본 연구를 통해서 대형 컨테이너 운반선의 그린쉽 설계를 위해 고려해야 할 사항을 살펴보았고 그에 따른 선형 최적화를 수행하였으며 설계 흘수와 실제 운항조건 및 연료 소모량을 고려한 총 에너지 효율식을 이용하여 최적화된 단축 및 상축 선형의 에너지 효율 개선을 확인하였다.

A study on the green ship design for Ultra Large Container Ship (ULCS, 18,000 TEU Class Container Ship) was performed based on the four step procedures of the initial design and hull form optimization to maximize economic and propulsive performance. The first, the design procedure for ULCS was surveyed with economic evaluation considering environmental rules and regulations. The second, the characteristics of single and twin skeg container ships were investigated in view of initial design and performances. The third, the hull form optimization for single and twin skeg ships with the same dimensions was conducted to improve the resistance and propulsive performances at design draught and speed by several variations and the results of the optimization were verified by numerical calculations of CFD and model test. The last, for the estimated operating profile of draught and speed, the hull forms of single and twin sked ships were optimized by CFD. From this study, the methodologies to optimize the hull form of ULCS were proposed with considerations during the green ship design and the improvement of the energy efficiency for the optimized hull forms was confirmed by the proposed formula of the total energy considering design conditions, operating profile and fuel oil consumption.
