초록

본 논문에서는 도서 지역 화물 및 승객 운송을 맡은 연안 항해용 친환경 차도선을 개발하면서, 검토된 주요 결과들에 대해서 논의한다. 시장에서의 경제성을 확보하기 위하여, 폭 19 m를 최종 개발모델 및 갑판면적에 많은 차량이 배치되도록 고려하였다. 조파저항 감소를 위해 선형 형상은 "V"에 선수벌수를 접목하였으며, 수치해석을 통해 개발 선박의 유체역학적 성능을 확인하였다. 선가를 직접 결정짓는 선각 중량을 감소하기 위하여, 최적화 전문 프로그램에 내재된 다목적 최적화 방법인 파레토 시뮬레이트 어닐링을 활용하여 약 3.9 %의 중량 절감을 달성하였다. 본 연구를 통해서 도출된 주요 결과들은 추후 쌍동형 차도선 관련 연구를 수행하는 엔지니어와 관련 산업에 좋은 선례가 될 것으로 기대한다.

This paper discusses the main findings of the development of the twin-hull Car ferry for island freight and passenger transport. The final model had a 19 m wide beam to create enough space for cars on the deck area and thus, enhance the economic feasibility in the market. The vessel had a V-shape with a bulbous bow to minimize the wave-making resistance and the hydrodynamic performance of the ship was verified through computational fluid dynamics. Multi-objective optimization problems of Pareto simulated annealing were used to achieve a weight reduction of approximately 3.9 % and reduce the manufacturing cost. The main results obtained in this study are expected to be useful to engineers and professionals in related industries interested in research on twin catamaran.
