  • In Korea-China shipping route, the level of freight rate has been maintained very low for last two decades not only because supply of shipping capacity is higher than its demand but also because the route was regulated by the two governments. An examination is made of the effects of openness of Korea-China Liner Shipping Route on competitiveness of Korean-flag Liner Shipping companies. This task is undertaken by detailing the development of the cargo sharing respectively by shipping companies of each country. Then it is suggested the ways to cope with the new environmental changes in Korea-China liner shipping route for the future by examining the future strategies for Korean-flag companies by in-depth interviews with major shipping companies.

  • This study verifies the change in market conditions in the Korea-China and Korea-Japan car ferry routes. Variation in historical development has led to differences in the lifecycle stages of these two car ferry shipping markets. However, previous studies have focused on individual car ferry routes rather than offering a more general understanding of this market. Based on the foregoing, we investigate the international car ferry market conditions from/to Korean ports, assess the management performances of car ferry companies, analyze the lifecycle stages of each car ferry route, and offer insights into the future of these markets. We show that the competitive market conditions and demands of passengers and cargoes differ between these routes. As for the market stage, we conclude that the Korea-China route is entering a mature market, whereas the Korea-Japan route is entering a declining stage.

  • 항로표지 관리운영시스템은 항로표지 상태정보의 감시제어 및 정보 제공 등을 위하여 지방청별로 설치시기 및 용역사에 따라 다양하게 운영하고 있다. 항로표지 관리운영시스템을 도입한 지방청들은 표준화되지 않은 관리운영 S/W를 현장 상황에 맞게 변경하여 각 지방청별로 관리운영 S/W의 구축 및 관리운영 예산의 중복투자 및 관리측면에서 어려움이 있다. IALA(국제항로표지협회)는 해사 안전 분야 국제표준인 S-100에 따른 항로표지 정보 표준인 S-201 규격을 개발 중에 있다. 이에 e-Navigation 도입을 대비하여 고도화된 항로표지 정보의 체계적이고 지속적인 제공을 위해 S-201을 적용한 항로표지 관리운영시스템의 표준 S/W 개발이 필요하다. 본 연구에서는 현재 운영 중인 항로표지 관리운영 시스템의 현장조사를 통하여 현황을 조사 분석하였다. 그리고 S-201 구조를 기반으로 한 항로표지 관리운영시스템용 DB 구조를 설계하였으며, 사용자 편의성 및 시스템 관리 효율성을 개선한 새로운 표준 시스템을 설계하였다.

  • To design ship channels is one of important factors for planning and developing a port. Bends in channels should be avoided if possible, but the channel should be widened, if channel bend is unavoidable, considering the swept path of a ship for safe passage. In this study, Variable Bumper Area(VBA) model is applied to determine the channel widths in bends. The result of this study shows that the width of the bend may be designed as nearly same size of that in straight channel in case that the angle of deflection is less than 30 degrees, and that of the bend with 60 degrees deflection should be widened based on the length of the largest ship using the channel and the angle of deflection.

  • 항로표지(Aids to Navigation)란 빛, 형상, 색채, 전파, 음향 등으로 안전한 항로를 표시하여 선박 항행의 안전성을 확보하기 위하여 인위적으로 설치하는 시설이다. 특히, 등대(Lighthouse)는 항로표지 중 가장 중요한 것으로 선박이 육지나 주요 변침점(Turning Point) 또는 선박 위치를 확인하기 위하여 연안에 설치하거나 항만의 소재, 항구 등을 나타내기 위하여 설치한 구조물이다. 본 논문에서는 선박의 입ㆍ출항에 관련하여 선박의 안전을 위해서 설치되어 있는 등대의 효율적인 관리 및 운영을 위한 등대 동기 제어 시스템의 개발에 관한 연구이다. 이를 위해서, 등대 동기 제어 시스템은 하드웨어(컨트롤 박스)와 소프트웨어(제어 프로그램)로 나누어 구성하였다. 하드웨어 모듈은 등대와 선박의 입ㆍ출항에 관한 업무를 담당하는 관제소 사이의 인터페이스를 제공한다. 즉, 등대의 점멸등 제어를 위한 제어부와 등대와 관리 시스템사이의 데이터 전송을 위한 통신 인터페이스를 마이크로컨트롤러의 한 종류인 PIC(Programmable Interrupt Controller)를 이용하여 구성하였다. 소프트웨어 모듈은 시스템 운영자가 등대를 간편하고 효율적으로 관리하기 위해서 GUI(Graphical User Interface) 형태의 인터페이스를 제공한다.

  • To design ship channel is one of important factors for planning and developing a port. Bends in channel should be avoided if possible, but the channel should be widened, if channel bend is unavoided, to account widened path of a ship in bend for the safe passage of a ship. In this study, Variable Bumper Area(VBA) model is applied to determine ship channel width in bend and channel-bend geometry. The result of this study shows that the width of a channel in bend may be designed as wide as the width in straight lane provided the angle of deflection is less than 30 degree, should be widened for 60degree deflection based on the length of the largest ship using the channel and the angle of deflection.

  • A significant growth in local air traffic volume is leading to airway congestion and flight delays especially for Incheon-China and Incheon-Europe sectors. A key method to increase the airway capacity is to place a supplemental airway parallel to the existing one and in cooperation between the aviation authorities between China and Korea, a dual airway track was implemented on December 6, 2018. Here, we use airline A's flight data to analyze the congestion change effect of the new airway. Results show total delay time to Europe is reduced 51% (13.4 to 6.6 minutes) as the delay distribution for 16-30 minutes, 31 minutes and greater decreased from 23.2% to 8.2% and 8.7% to 1.0% respectively. The delay to China also decreased but the drop is not as significant as flights to Europe. This is caused by the difference in flight distance, traffic volume, and characteristics of flights landing and transiting China. Flights to Europe show a broad distribution in altitude allocation and reduction in aircraft separation demonstrating the effectiveness of a dual airway track.

  • This paper considers the Marine Traffic Risk Assessment for fixed and moving targets, which threaten officers during a voyage. The Collision Risk Assessment Formula was calculated based on a dynamic ship domain considering the length, speed and maneuvering capability of a vessel. In particular, the Navigation Risk Assessment Model that is used to quantitatively index the effect of a ship's size, speed, etc. has been reviewed and improved using a hybrid combination of a vessel's dynamic area and the Collision Risk Assessment Formula. Accordingly, a new type of Marine Traffic Risk Assessment Model has been suggested giving consideration to the Speed Length Ratio, which was not sufficiently reflected in the existing Risk Assessment Model. The larger the Speed Length Ratio (dimensionless speed), the higher the CJ value. That is, the CJ value is presented well by the Speed Length Ratio. When the Speed Length Ratio is large, states ranging from [Caution], [Warning], [Dangerous] or [Very Dangerous] are presented from a greater distance than when the Speed Length Ratio is small. The results of this study, can be used for route and port development, including dangerous route avoidance, optimum route planning, breakwater width, bridge span, etc. as well as the development of costal navigation safety charts. This research is also applicable for the selection of optimum ship routing and the prevention of collisions for smart ships such as autonomous vessels.

  • The route of Korea and China situates stable shipping market by the agreement on maritime transport between two countries. Epecially, the Car-ferry shipping market between Korea and China is growing up the world's largest markets in this situation. But, the rapid growth of markets have the possibility of imbalance between supply and demand. In addition that heavy competition can be arisen. The aim of this study is to analyze the ways to reinforce competitiveness of Car-ferry shipping companies(CFSCs) between Korea and China routes through suggesting importance weights of service factors. Firstly, evaluating service factors of CFSCs between Korea and China routes are selected by reviewing literatures and Delphi method. Secondly, importance weights of service factors are calculated using Fuzzy method. As a result, Shipper and CFSCs between Korea and China routes select 'agility of loading and unloading', 'agility of customs', and 'punctuality of transportation' as the most important factors. On the other hand, the two groups are shown the perception gaps on the factors such as 'reasonable shipping cost', 'voyage speed', 'multimodal transportation', and 'professionality of manpower'. The implication of this study is that Government of Korea and China Have to cooperate agreement for mutual drive towed trailer and customs to speedy transportation.
