The VTS concept was located as a principal methods of maritime safety administration in world's major harbors and expected to become the pivotal role for the future of the maritime and harbor society with e-Navigation epoch. If recent limelight concept of big-data has been included in aspect of information gathering and analysis with various studies, it's required advanced studies to improve the information analysis capability and application range of the data that can be mining by the VTS. In this study, contrast to other studies that aimed quantitative analysis as communication number, it can be mining the time information and each of the communication VTS for the target vessel, including qualitative analysis, such as the purpose or the type of communication. This comparison across multiple items of the collected information, and presenting the VTS data mining model (VCDF) that can be analyzed for the purpose of analyzing way, type and number of communication by ship's type, also number of violations through VTS communication. First, In Busan port case, it shows frequently information service and shows frequently communicating with particular types of vessels. Second, Passive VTS carried out notwithstanding many kinds of traffic violations due to communication congestion. This arranged information can be used as data for the analysis, as possible the level of traffic for VTSO situational awareness, which pointed to the 'workloads' in 'IALA Guideline' and could be used as a database for future research of e-Navigation.

Vessel Traf ic Services (VTS) is a system for ship safety and accident prevention. The International Maritime Organization (IMO), the International Association of Marine Aids to Navigation and the Lighthouse Authorities (IALA) established regulations related to VTS from an early stage. On December 3, 2019, South Korea enacted a special act called the "Act on Vessel Traffic Services (VTS Act)," which will take ef ect on June 4, 2020. In this paper, the background of this act's enactment is examined and its provisions are critically reviewed. In particular, the study intensively examines the reasons the immunity provisions for the VTS operator were removed and the current direction of improvements to the VTS Act is presented in terms of its feasibility. Most countries that do not have an Act related to VTS and its operator, refer to that of Korea. Therefore, it is necessary to reinforce the structures and definition of the VTS Act, as well as the immunity provisions for the VTS operator. The latter were removed during the National Assembly's legislation process, but were included in the initial bill, and should be reflected in subsequent revisions of the VTS Act.

VTM is regarded as a core element in e-Navigation under developing by IMO. IMO's e-Navigation aims for VTM which could provide more navigational information for ships and provide more active VTS services for safe and efficient marine traffic environment. To be successful for VTM under e-Navigation, VTS operator's experience and ability for carrying out VTM tasks are essential. In this study, Decision-making support system for VTS operators are designed conceptually which support VTS operators' VTM tasks by providing informations on traffic risk, and predicted behaviour of ships. This paper describes a designed system with design concept, main functions, main elements and necessary technologies to be developed.

The congestion situation of Korea's port is further inclining due to the number of arriving and departing vessels and increase in the size of the size. Indicators for assessing whether the Vessel Traffic Congestion is called the Marine Traffic Congestion and it is used as a diagnostic entries in the Maritime Traffic Safety Audit System. In the diagnostic system, 6L (longitudinal) X 3.2L (transverse) is used as ship's domain in cases of harbor. This study is to determine the safety distance of the VTS officer and the ship operators by targeting the Busan harbor, which has the most number of ships that arrive/depart in Korea and listen to the communication of the VTS and calculate the communication time of the VTS officer and the ship operators for 7 days. By utilizing the distance communication port, the safety distance between the controllers and the ship operators is derived. It can be used for basic information of VTS Officer and Ship's operator's Safety distance in Busan port's in&out harbor.

Today the role of Vessel Traffic Service(VTS) is increasing due to the function to preserve the safety of marine traffic and harbour, improve the efficiency of harbour, protect the marine environment. However, Vessel Traffic Service(VTS) lacks the international and domestic legal basis. For this reason it is hard to fulfill the positive and systemic operation of Vessel Traffic Service(VTS). It is essential to establish a domestic legal basis upon which to perform function and role of Vessel Traffic Service(VTS) fully. The purpose of this study is to propose the directing point for the adequate regulation of vessels to participate in Vessel Traffic Service(VTS) by doing a comparative analysis between domestic regulations and other countries's regulations.

To ensure the safety for vessels anchored in stormy weather, duty officer and VTS operator have to frequently check whether their anchors are dragging. To judge dragging of the anchored vessel, it is important for VTS operator to recognize the turning circle and its center of the anchored vessel. The judgement for the anchored vessel dragging can be made by using Radar and AIS. If it is available, CCTV or eye-sighting can be used to know the center of turing circle. However, the VTS system collects individual ship's dynamic information from AIS and ARPA radar and monitors of the anchored vessels, it is difficult for VTS operator not only to get the detailed status information of the vessels, but also to know the center of turning circle. In this study, we propose an efficient algorithm to estimate the center of turning circle of anchored vessel by using the ship's heading and position data, which were from AIS. To verify the effectiveness of the proposed algorithm, the experimental study was made for the anchored vessel under real environments.

At recently, Oil spill accident of large size oiler that happen domestic and outside the country is occured to social impact us as well as economical damage in sea environment. Also, because spread extent of pollution accident is reaching harbor, bay and close water areas, as necessity that traffic control ships are sea place. VTS is changing to concept that control space is magnified gradually. Our country is operated to 14 harbors which is control center. But abroad is operating coastal VTS that do main waterway and coastals to authority dimension. Therefore, necessity that traffic density of ship manages high coastals and ship traffic of waterway to our country is risen. This paper is execute sea traffic survey at Mokop sea areas and sea casualty occurs. It proposal that coastal VTS center field of most suitable and position of radar site.
