This paper deals with the structural assessment of metallic and non-metallic stiffened/monocoque plated marine structures under a lateral pressure load to identify appropriate combination of material and section configuration, especially at the preliminary marine structural design stage. A generic rectangular plated structure is exemplified from the metallic superstructure of a marine vessel and its structural topology is varied for the structural assessment. In total 13 different structural topologies are proposed and assessed using appropriate elastic solutions in conjunction with a set of stress and deflection limits obtained from practice. The geometry dimensions and weights of the structural topologies are calculated, and subsequently, the costs of the materials used in the structural topologies are reviewed to discuss the cost-effectiveness of the materials. Finally, conclusions are made with the aim of suggesting suitable structural topology for the marine structural member considered in this paper.

1. 서 론 최근 국내에서는 해양수산부장관배 국제요트대회 및 새만금 국제요트대회 등 다양한 요트대회가 개최되고 있으며, 2015년 해양수산부에서 해양신사업 육성과 일자리 창출을 위한 '마리 나산업 전략적 육성대책'을 발표하면서 요트에 대한 관심이 높 아지고 있다(Kim et al, 2016). 해양레저장비 중 선박으로 분류 되는 것은 크게 동력으로 추진하는 파워보트와 바람의 힘으로 추진하는 세일 요트로 나누어진다. 이 중에서 국내에서 진행된 세일 요트에 관한 연구 현황을 살펴보면 주로 조선공학적 해석 을 다루고 있다. 관련 연구로 Ji et al.(2010)은 세일링 요트의 구 조적 안전성평가에 대한 연구로 유한요소해석을 통하여 안정성 평가를 수행하였고, Shin et al.(2006)은 해양레저 선박으로서 소 형 요트의 기본구조설계 및 구조해석 기법을 제시하였다. 한편, 일반적으로 레저보트 대부분의 공간이 협소하여 인간공 학적 배치 및 사용을 위한 연구가 필수적이라 판단된다. 하지만 세일링 요트와 관련된 설계 규정에 인간공학적 고려가 일부 언 급되고 있으나, 침실 및 생활공간에 대한 고려일 뿐 윈치 등 리 깅류에 대한 인간공학적인 설계기준이 적용된 사례는 찾아보기 어렵고, 이에 대한 인간공학적 연구 또한 드문 편이다. Kim et al.(2013a)은 세일링 요트 운항 시 발생하는 크루(Crew) 의 이동 동선을 분석하고 각각의 주요 임무에서 발생하는 자세 들을 분석하여 해당 자세의 위험성에 대한 기초연구를 수행하 였다. 또한, Kim et al.(2013b)은 수치 휴먼 모델링(Digital human modeling)의 인간공학적 분석기법을 이용하여 세일링 요트 운항 시 발생하는 작업 자세를 크게 7가지로 분류 하고, 전문가와ABSTRACT: Unlike other leisure boats, a sailing yacht is propelled by wind power using sails that are controlled by the crew. Therefore, the ergonomic design of the equipment that the crew has to operate for sailing might be very important. However, it is difficult to find design rules and regulations for the equipment arrangement of a sailing yacht based on ergonomics. In this study, the arrangement design for the height and side plate angle of a winch for a sailing yacht was examined from an ergonomic design point of view. In a simulation, a Korean male in his 20s was selected as a human model for a grinder. The physical load was analyzed when he was operating a winch using a 3D human simulation. The lower back load showed the highest value when using the grinder at 90° and 180°. Based on the results for the lower back load when using the grinder with various winch heights, it is suggested that the winch height from the cockpit floor to the top of the winch should be more than 40% of the height of the human operator. In addition, according to the results for the lower back load with various horizontal distances from the body, it is suggested that the side plate angle should be less than 16°.This is an open access article distributed under the terms of the creative commons attribution non-commercial license (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

The prototype of 20 feet class power boat was developed and authors are joined in this government-led project. The research was performed to evaluate the optimal structure and design of the structural strength necessary to ensure the structural safety of the power boat.A new material ROCICORE fiber added to the mat and roving was adopted for high-power tenacity. ANSYS Workbench has been used to make the structural model, evaluate the strength and optimize the structural design. The response of the structure to quasi-static slamming loads according to the rules and regulations of ISO 12215-5, Lloyd's Register of Shipping and Korean Register has been implemented and studied. An optimization study for the structural response is carried out by changing the plate thickness and section modulus of stiffeners. The power boat structure derived fuel efficiency is optimized by performing the best possible structural design to minimize the hull weight.
