Abstract

In this study, a minimum weight design and sensitivity analysis were conducted for the Fairlead Chain Stopper (FCS), a detachable mooring system designed for application to a 10 MW-class floating offshore wind turbine. The Orthogonal Array Design (OAD) was employed to systematically evaluate the influence of design variables. In the OAD, the thickness dimensions of the primary components of the FCS were selected as design factors, while the responses were defined as structural weight and strength performances. The suitability of the OAD experimental matrix configuration was verified by constructing a response surface model and assessing its approximation accuracy. The minimum weight design of the FCS was determined based on the optimal configuration derived from the OAD results. Furthermore, through sensitivity analysis, the design factors with the most significant effect on each response were identified.

본 연구에서는 부유식 10MW급 해상풍력발전기에 설치하기 위해 설계된 탈착형 계류 시스템인 Fairlead Chain Stopper (FCS)에 대해 직교배열실험법 (Orthogonal Array Design, OAD)을 이용한 최소중량설계와 민감도 평가를 수행하였다. OAD에서 FCS의 주요 구성품의 두께 치수는 설계인자로 고려하였고, 응답치는 중량과 강도성능으로 선정하였다. OAD의 실험행렬 탐색 및 구성의 적합성은 반응표면모델을 생성하여 근사화 정확도의 평가를 통해 수행하였다. FCS의 최소중량설계은 OAD의 최상 설계안의 결과로부터 결정되었고, 민감도 평가를 통해 응답치 별로 영향도가 높은 설계인자가 파악되었다.
