A passenger ship has some differences compared with a general commercial ship from the viewpoint of the structural arrangement. It is difficult to reinforce wide panels and local structures of a passenger ship because of its interior design when they have vibration problems. Moreover, the allowable vibratory limit for a passenger ship is much lower than that of a commercial ship. In this study, it is introduced that the procedure of the vibration analysis and the structural improvement for prevention of vibration with consideration of interior design for the Atrium stairway, one of the local structure installed in public space.

The new commercial maritime law in the Kingdom came comprehensive and detailed for all topics related to commercial maritime navigation, thus responding to most of the problems that arise in the field, specifically regarding the ship as the focus of the rules of maritime law. This system defines the ship in law, regulates its civil status, determines how to name it, determine its domicile, and the conditions for acquiring Saudi nationality. It also contained a regulation of the rights granted to ships by ownership, as well as their lease and mortgage, the mechanism of attachment to them to settle debts and the rights in kind dependent on them and controlling the rights of third parties on ships and the procedures for forcibly selling them from precautionary seizure and executive seizure and then forced sale in public auction. Until this research was an effort to present a clear picture about the legal system of the ship in the new Saudi commercial maritime system and confirming the extent of the success of the Saudi legislator with the ship system in highlighting the legal frameworks for this facility prepared for maritime navigation.

Navy ship acquisition management business contributed to the korean Navy and defense exports with government suppliers in Korea for over 40 years. But due to advanced technology, development trend of Navy ship and defense export requirements, it enable to make a contribution to a better system improvement are being demanded. In this paper, an adjective Navy ship acquisition process is presented in order to improve the acquisition process takes the first step for acquisition planning process to enhance the efficiency and rationality that is based on consensus of Navy ship expert and experienced. In addition, systems engineering (SE) and quality control (QC) techniques based on Modeling and Simulation are investigated to carry out efficient project management and scientific quality control system in Navy ship acquisition process. Finally, it is suggested to apply SE/QC based on M&S for Navy ship acquisition process using civilian infrastructure and organizations in order to take advantage of the world's leading domestic industry based on considering the difficult conditions of Navy ship suppliers.

In view of the problems of insufficient data collection and processing capability of multi-source heterogeneous equipment, and low visibility of equipment status at the ship block construction site. A data collection method for ship block construction equipment based on wireless sensor network (WSN) technology and a data processing method based on edge computing were proposed. Based on the Browser/Server (B/S) architecture and the OneNET platform, an online monitoring system for ship block construction equipment was designed and developed, which realized the visual online monitoring and management of the ship block construction equipment status. Not only that, the feasibility and reliability of the monitoring system were verified by using the intelligent tire frame system as the application object. The research of this project can lay the foundation for the ship block construction equipment management and the ship block intelligent construction, and ultimately improve the quality and efficiency of ship block construction.

This study aims at exploring the characteristics of interior design of the Cruise line running Korea, Japan and China, and the satisfaction level of the Korean passengers for the interior design. Literature review and the physical traces of the cruise ship interior including 4 types of cabins and public spaces such as main hall, restaurants, outdoor swimming pool, jogging track, theater, meeting room, duty-free shop were performed. Also, the questionnaire to the passengers were used to understand their preferences and satisfaction level for each space. The results show that the passengers are very satisfied with the color and atmosphere of the cabin, while they complain the inconvenience of the bathroom size. Also in the public space, they prefer western classic style and modern style rather than Asian or Korean style. This means that they want the exotic feeling coming out of home. Also they prefer buffet restaurant, duty-free shop, theater, observation platform compared to other public spaces. However, the problem is that there are no place for the Korean family members with young children except for the outdoor pool. The interior and the program should be redesigned for the public spacs such as cinema room, family karaoke and internet-free room for Korean passengers.

To prevent pollution from ships, the Energy Efficiency Design Index (EEDI) is a mandatory guideline for all new ships. The Ship Energy Efficiency Management Plan (SEEMP) has also been applied by MARPOL to all existing ships. SEEMP provides the Energy Efficiency Operational Indicator (EEOI) for monitoring the operational efficiency of a ship. By monitoring the EEOI, the shipowner or operator can establish strategic plans, such as routing, hull cleaning, decommissioning, new building, etc. The key parameter in calculating EEOI is Fuel Oil Consumption (FOC). It can be measured on board while a ship is operating. This means that only the shipowner or operator can calculate the EEOI of their own ships. If the EEOI can be calculated without the actual FOC, however, then the other stakeholders, such as the shipbuilding company and Class, or others who don't have the measured FOC, can check how efficiently their ships are operating compared to other ships. In this study, we propose a method to estimate the EEOI without requiring the actual FOC. The Automatic Identification System (AIS) data, ship static data, and environment data that can be publicly obtained are used to calculate the EEOI. Since the public data are of large capacity, big data technologies, specifically Hadoop and Spark, are used. We verify the proposed method using actual data, and the result shows that the proposed method can estimate EEOI from public data without actual FOC.

본 연구는 우리나라 연안여객선이 다수 운항하고 있는 인천, 목포 및 통영 등 3개 지역의 연안여객터미널에서 승선 대상자(여객선 수요자)를 대상으로 여객선운항과 관련된 여러 주제에 대한 승선자들의 인식을 조사 분석하였다. 설문조사기간은 코로나19가 발생되기 바로 이전인 2019년 10월 1일~10월 11일, 표본수는 277개, 주요 내용은 여객선 운항 및 시설 측면, 여객선 운임 측면, 여객선 안전 측면 등 크게 3가지 요소로 나누어 분석하였다. 분석결과 도서민과 일반인이 모두 50% 이상의 긍정적인 답변을 하지 않은 항목은 교통약자시설 우수성, 운임의 적정성, 운임 안내 적절성 등과 운임 종합평가로 교통약자시설에 대한 정책 및 운임 정책에 대한 보다 면밀한 검토가 필요하다는 점을 알 수 있었다. 본 연구가 코로나19이후 리오프닝을 대비하고, 대중교통화 정책에 활용될 수 있을 것으로 기대한다.

본 연구는 세계적인 크루즈 선박들의 거주구역 실내 공간의 일반적 특성과 경향을 분석하고자 하였다. 또한 한중일을 중심으로 하는 아시아권 크루즈 선박의 공용공간과 객실공간에 대해 각 실별로 구체적으로 디자인 특성을 파악하여 크루즈 선박의 공간 디자인을 위한 기초 자료를 제공하고, 추후 나아가야 할 방향을 제안하였다. 연구결과, 한중일을 운항하는 두 선박은 각 선사 고유의 컨셉을 바탕으로 모던과 하이테크 스타일이 주를 이루고 있다. 두 선박은 공용공간에서 개방감을 표현하는 방법에 있어서 시각적, 심리적으로 표현하는 방법과 공간적으로 표현하는 방법으로 확연하게 나뉘어졌다. 컬러의 대비를 통해 공간의 볼륨감을 주고 외부의 빛이 들어 오는듯한 효과를 주어 공간의 개방감을 표현하였다. 본 연구는 세계적인 크루즈 선박의 거주 공간의 실내디자인 특성을 이해하고, 추후 크루즈 선박 실내 디자인 개발을 위한 유용한 기초 자료를 제공할 것으로 기대한다.
