국제 표준 규칙을 따르는 소형 쌍동선의 초기 설계 절차

초록

Leisure boat and yacht should be designed to meet the domestic regulation and international standards as large merchant vessels. Recently, ISO (International Standards Organization) is required to be applied to the design and construction of leisure boats such catamarans and small yachts. Furthermore domestic rule for the design of catamaran has not activated by domestic rule or regulations. This study has developed the rule scantling programs that can be used to design the sailing catamarans based on ISO TC-188 in 12215 rule and Lloyd register rules. Using the program, we calculate the design load and estimate the attributes of the structural members that are supposed to satisfy the regulation and standards. High speed boat design rule of Korea Register (KR) and scantling rules defined in special service craft of Lloyd Register (LR) rule are compared with that of ISO international standards. In order to get the magnitude of design load and structural strength, FRP catamaran and Aluminum catamaran are analyzed by finite element analysis. The structural strength of the catamarans is assessed based on the design load suggested by KR, LR and ISO standard. Thereafter, the structural strength and structural design requirement of each classification rule and ISO international standard are compared. Finally, the initial design procedure and the appropriate structural strength evaluation processes that can be applied to the catamaran design are explained.
