초록

본 논문에서는 쌍동형 카페리에 대한 기본구조설계 및 구조해석을 위한 기법을 제시한다. 카페리와 같이 길이가 50미터 이상이고, 길이/폭의 비가 12보다 큰 중/소형 고속선박의 강도해석에 대한 규정이나 방법론은 아직까지 명확하게 제시되지 않고 있다. 따라서 본 논문에서는 한국선급 규정을 이용하여 부재 스캔틀링을 수행하였고, 설계안에 대한 구조강도 검증을 위해서 카페리 전용선박 기준을 추가적으로 적용하여 검토하였다. 특히, 카페리 전용선박 기준을 이용하여, 선체거더 최종강도를 추가적으로 수행하였으며, 기존 기준에 의한 설계의 모호성을 극복하도록 제안하였다. 본 연구를 통해 도출된 연구 결과는 앞으로 고속 쌍동형 카페리의 구조설계 및 구조해석에 관련된 기본적인 자료로 유용하게 활용될 것으로 예상되며, 현재 설계된 쌍동형 카페리의 부재 치수는 한국선급 기준에 충분히 만족하면서 구조적으로 안전하다.

This paper suggests study of basic structure design and structural analysis for the twin car-ferries. The rules and methodology for the strength analysis of medium and small sized high speed vessels with a length of more than 50m and a length/width ratio of more than 12, such as car-ferries, have not been clarified yet. Therefore, in this paper, the members scantling were carried out using the KR Rule, and the car-ferry exclusive vessel standard were further applied to verify the structural strength the design. The scantling of the members is based on the Korea Classification standards, and the car-ferries standards were additionally applied to verify the structural strength of the design. Especially, the ultimate strength of hull girder was additionally carried out by using car-ferry exclusive vessel standard, and proposed to overcome ambiguity of design by existing standard. The results of this study are expected to be useful as basic data related to structural design and structural analysis of high speed twin-hull car-ferries. The present car-ferry design has a sufficient safety margin in strength point of view according to the KR rule.
