글로블 대형요트산업은 리먼사태 때 잠시 주춤했지만 여전히 고속성장하는 고부가가치산업으로, 이탈리아, 네덜란드 터키 등 유럽의 해양레저선진국이 거의 시장을 주도하고 있다. 우리나라의 경우 아직 대형요트를 건조한 실적은 전무하지만, 중소형조선소가 경제적 어려움을 겪는 현시점에서 국내 조선기술, 부품소재기술, ICT 등 관련기술수준을 감안한다면 진출해볼만한 신성장분야인 것은 분명하다. 이 연구에서는 메가요트 국산화 개발방안을 제시하고자 한다.

카이트 보딩은 윈드서핑, 요트 등과 같이 바람을 이용한 수상레저기구이며 국내에서는 소수의 동호인을 중심으로 매니아 층을 형성하고 있다. 최근 해양레저장비 분야에서도 친환경기술과의 접목이 진행되고 있으며, 특히 해외에서는 대형선박의 연료비 절감 및 환경오염 인자 저감을 위한 선박 추진용 카이트 시스템이 개발되어 사용 중에 있다. 본 연구에서는 카이트 추진형 레저보트를 대상으로 풍속, 풍향, 카이트의 위치 등에 따라 자동제어 및 운항 가능한 시스템을 제안하고자 한다.

이 연구는 충돌을 피할 수 없는 상황에서 유지선박의 충돌회피협력 동작 시점을 제시하기 위한 연구다. 관련된 기존 연구에서는 하나의 모델 선박을 본 선박과 상대 선박으로 간주 하였다. 그리고 선박의 항적 계산에 해상상태가 고려되지 않았다. 본 연구는 기존의 연구에서 식별된 한계점을 보완하였다. 선박의 항적은 조류, 파도, 바람을 고려하여 계산 되었고, CNN-LSTM을 통해 충돌 직전 항적을 예측 하였다. 모델선박은 벌크선박, 컨테이너선박을 본 선박으로 지정하였고, 상대 선박은 30미터 요트에서 400미터 대형 컨테이너선까지 고려하여, 다양한 상황에서 유지선박의 충돌회피 협력 동작 시점을 제시 하였다.

The aim of study is to develop a dual driven ship berthing/deberthing system with $360^{\circ}$ steerability. A large ship used bow thruster, side thruster and pod propulsor etc. when approaching to a pier. But as marine leisure boats become large-scaled, the number of accidents is recently increasing what caused a ship to crash into a ship and a ship to crash into mooring facilities during berthing/deberthing on a marina. To solve the problem, the control responsiveness of a joystick connected with two motors and a propeller was checked and torque was increased by the electromagnetic design of magnetic gear. A sea trial test was carried out to investigate a performance of the developed system in the real sea.

Marina and marina clubs are the essential structures to meet increasing marin tourism and marin leisure sports demand. According to the domestic situation, marina and marina clubs are divided into 6 types such as small sports type, small complex type, midium sports type, midium complex type, large sports type, large complex type. As a result of analysis of domestic three marina clubs, averagely marina facilities take 21% and commercial facilities take 79% of total space. In the short term, marina club should be designed focusing on complex program. Marina club will be for long-term transformed into marin leisure sports program. Additionally, it is certain that floating marina club is an architecture to have water-friendly space and to maximize marin tourism and marin leisure sports.

Due to diversification of ships and limited space of pier, when ships come alongside the shallow water or narrow pier, sea area with small mooring facilities and floating matter is frequently applied. Through these, coming alongside the various space is capable and cost effectiveness is enhanced. However, when ships, applying small mooring facilities and floating matter, come alongside, there can be some impulse by waves between the floating things and ships which possibly leads to mass disaster. Therefore, there should be forecasts and analysis of the movement caused by waves. On this study, we develop measuring system for movement analysis of mooring and floating matters which provides base data with movement traits by measuring 3-D exercise information and acceleration at mokpo maritime university marina facility. Also, the composition and principles of the developed system is explained.

The research aims to provide its results to each municipal corporation after an in-depth analysis of its optimum demand and also the significance of post-development location selection. The research results, related to the future development of Marina from the municipal corporation, are as follows: There are approximately 49 proper domestic demands after the Marina development. In further detail, there must be a development of the coastal zone Marina concept after classifying the regions to their Metropolitan areas and networking the Marina to each section. Moreover, the classification of the Marinas to small, medium, and large size is of absolute necessity. Regionally, 10 large Marinas must be developed for metropolitan area (2), Chungcheong area (1), Jeolla area (2), Gyeongsang Provinces (3), Gangwon area (1), and Jeju (1). The 17 mid-sized leisure sports Marinas must be developed for metropolitan area (3), Chungcheong area (2), Jeolla area (2), Gyeongsang Provinces (6), Gangwon area (2), and Jeju (2). The rest of 22 small Marinas must be developed for metropolitan area (2), Chungcheong area (1), Jeolla area (6), Gyeongsang Provinces (9), Gangwon area (2), and Jeju (2). In addition, there is an evident result of significant importance in the domestic positions of appropriate Marina development. A group of professionals suggested five key factors contributed to the importance including accessibility, marketability, usability, validity, and natural environment. The results, aimed to show comprehensive importance based on the five factors, ranks in the following order from highest to lowest: usability, accessibility, natural environment, marketability, and validity.
