Since the past, ships have hoisted national flags as a means of indicating their nationality. Both domestically and internationally, laws and conventions related to the nationality and hoisting of the flag have been enacted because it is significant that the nationality of a ship is a matter of the jurisdiction of the ship. Nevertheless, there are differences in domestic and international regulations related to the hoisting of the flag of a ship, and if the flag is not hoisted irrespective of the intention, there may be a difference in interpretation as to whether or not the ship will be regarded unconditionally as a stateless ship. However, there is no disagreement locally or abroad about the necessity of indicating the nationality of ships. Therefore, I would like to propose a method to indicate and confirm the nationality of the ship by using wireless communication equipment with hoisting the flag as the only way to express its nationality, reflecting the situation of the era such as high-speed, larger and unmanned ship. Representatively, the method utilizes the automatic identification system(AIS), which is one of the equipment legally installed in the ship, and includes the ship's nationality in its information. If the nationality information is included in the AIS, nationality can be identified earlier and even from a distance, and there will not be instances of nationality not being identified because the flag is not hoisted or the flag is damaged. In addition, it is expected that the problem of nationality indication can be solved even when vessels are unmanned in future.

In this study, we installed the Automatic Identification System (AIS) receiver on the Ieodo Ocean Research Station (IORS) from November 21 to 30, 2013 in order to monitor marine traffic and fishery activity in the jurisdictional sea area. The collected AIS raw data consist of static data report (MMSI, IMO NO., Call Sign, Ship Name, etc.) and position information report (position, speed, course, etc.), and the developed program was applied to classify ships according to ship flag and type information. The nationalities are released from the first three-digit numbers (MID) of MMSI, but in general most of small ships do not send an exact ship flag through Class B type AIS, a simplified and low-power equipment. From AIS data with flag information, ships under the flag of China had the highest frequency and the second was Korean flag, while in ship type cargo and fishing vessels were dominant in sequence. As for the ships without flag information, we compared the tracks with others in order to estimate ship flags. It can be said that fleets of ships with Chinese frequently appear sail together for fisheries over the waters, because the unknown ships followed a similar moving pattern with Chinese fishing vessels.

오는 7월 1일부터 전면 발효되는 ISPS Code에 대비하여 세심한 준비가 요구되고 있다. ISPS Code 시행시기가 4개월밖에 남지 않은 현재 국적선의 경우 ISPS Code를 이행하기 위한 준비단계에 불과한 선박보안계획서(SSP)의 승인은 회원사 소속 선박 380여척 중 비국적선의 경우 110척, 국적선의 경우도 110척에 불과해 준비를 서둘러야 할 상황이다. 국제 보안증서를 취득하기 위해 소요되는 시일이 대략 75일 소요되는 점을 감안할 때, 늦어도 3월 말까지는 보안계획서 승인을 신청해야 하기 때문이다.

한국선급(KR) 등록선박 중 지난 2011년부터 46개월간 항만국통제(PSC)를 수검한 총 170척을 대상으로 선종별, 선령별, 기국별, 수검국가별 및 수검분야별 결함사항 등을 조사, 분석하였다. 분석결과 국적선의 출항정지율은 점차 낮아지고 있으나 24.7%의 선박이 Code-30을 받은 결과로 나타나고 있다. 수검선박 분석에서 선종별에서는 벌크선이 37.1%, 선령별에서는 21년 이상의 선박이 31.2%, 기국별에서는 파나마국적 KR 등록선박이 41.8%, 수검국가별은 중국이 27.1%로 가장 높은 비율을 차지하였다. 수검분야별 결함사항 분석에서는 기관설비가 41.9%로 가장 높았고, 다음으로 각종 서류가 23.5%의 비율을 보였다.

There is scant of research regarding the efficiency measurement of the ship management business. This paper aims to analyze the relative efficiency within the Korean Major Ship management corporations, to select the relatively low effective companies, and to suggest the improvement strategies for those. As a research methodology, Data Envelopment Analysis (DEA) applied to the top 20 corporations among Korean and Foreign Shipping Liners in Korea. To draw out the efficiency of targeted terminals, the number of ship managed is used as an input variables while, the number of crews and the total sales are utilized as an output variables. As a result. Haeyoung Maritime services is the most efficient corporations in Foreign Shipping Liners. Among Korean Shipping Liners, Panstar Shipping, Korea Lines, STX marine and Woolim Shipping are relatively efficient corporations which are scored BCC 1.
