울산항 해상교통관제센터(VTS)에서 수신한 AIS 데이터를 이용하여 울산항 출입하는 선박의 MMSI 정보를 분류하였다. 분류된 MMSI 정보는 웹 크롤링을 통하여 선박의 종류, 국적, 총톤수, 길이, 폭 등을 데이터를 수집하였다. AIS 데이터와 MMSI의 선박 정보를 이용하여 출입하는 선박의 선종별 운항 경로 궤적을 분석하였다. 분석된 데이터는 선박 도선 및 항내 안전항로 유도에 활용하고자 한다.

Foreign maritime officers were employed in Korean flag ocean-going merchant ships since the year of 2005. And the number of foreign maritime officers in Korean ship has been rapidly increased, and it approaches 700 recently. The shortage of Korean maritime officers was mainly claimed the reason of employing foreign maritime officers in Korean flag ship. In this paper, we surveyed the number of newly supplied officers from every Korean training institution, the number of officers on-board, on-leave, on-job hunting, and the number of officers leaving their job every year. And then we analysed supply-demand situation of Korean maritime officers for Korean flag ocean-going ships for reasonable decision-making in relation with employing foreign maritime officers.

The purpose of this study is to classify national ships into passenger ships, cargo ships, oil tankers, tugboats, barges, and other ships by use, and compare the rate of change and direction respectively. In this study, a total of 123 monthly data were searched from January 2011 to March 2021 in Statistics Korea's KOSIS "Traffic Logistics => Operating Vessel Statistics => Possesion State of National Vessels". To this end, we calculated the rate of change from the previous month for each ship and performed numerical analysis and model analysis. In the correlation analysis, the Total showed a high relationship in the order of Towing, Barge, Oil, Cargo and Ferry. In the regression analysis, each ship was found to be statistically significant and varied independently of each other. The increase rate was highest in the order of Ferry, Oil, Towing, Barge and Cargo during the last analysis period. In the analysis of Scatter Charts, Towing and Barge showed more than a certain level of synchronization with respect to the Total. The synchronization phenomenon for each ships was calculated to be rather low, indicating that the correlation between each ships was low. However, the correlation between Oil and Towing, Oil and Barge and Towing and Barge is relatively high, indicating a relatively large correlation.

Recently, the reduction of greenhouse gases(GHG) for climate change is the most important international issue. In order to control efficiency GHG emission rate reduction, it is essential to establish GHG emission inventory preferentially. The emission of ships that are emitting its $CO_2$ in international waters is becoming chief among the issues which country is put under an obligation. In the IMO reports, shipping is estimate to emit 1,046million tonnes of $CO_2$, which corresponds to 3.3% of global emission during 2007. International shipping is estimated to have emitted 870 million tonnes, about 2.7% of global emission of $CO_2$ in 2007. In this study, the general information of GHG emission, based on fuel consumption statistic, Tier 1, and the emission inventory is calculated to break down in to domestic and international emission. The GHG emission from ships in Korea was total 31,646 Gg $CO_2$-eq in 2009, which is included fishing, Korea flag coastal ship, Korea flag ocean going ship and foreign flag ships. And domestic emission and international emission was 5,398Gg $CO_2$-eq, 7,630Gg $CO_2$-eq and foreign flag ship was 18,618Gg $CO_2$-eq respectively.

A question has recently been raised as to whether a foreign officer needs to obtain a Korean endorsement in order to be able to serve on board a Korean flag ship. This is attributable to the fact that differences of viewpoint may arise as to the interpretation on the relation between the mutatis mutandis article 24(1) and the endorsement issuance article 10 bis. This study intends to propose an interpretative solution through conducting in-depth analysis on the article 25(1). The conclusions of this study can be given as follows. First, the jurisdiction over the bareboat charter ships with hire purchase shall be rested with the third country of which the flag the ship is flying, the endorsement to be issued to foreign officers have to be issued by the flag State under the STCW Convention as ameded. Second, the provisons of the ship officers' act shall not be made applicable, commensurate with the intention of legislating the mutatis mutandis article 25, to the BHC/HP in such a way that is in infringement with the jurisdiction of flag State of those foreign ships. Third, the mutatis mutandis article shall be made applicable to only such areas of manning standards not covered under the STCW Convention as amended and shall exclude those provisions pertaining to the issuance of various certificates of which the jurisdiction is rested with flag State under the international instrument. Fourth, the article 10 bis(1) is not a provision requiring foreign officers wishing to serve on a BBC/HP to obtain a Korean endorsement. In summation, the article 10 bis shall be used only in the cases where foreign officers wishing to serve on a Korean flag ship are required to obtain korean endorsement.

한국형 e-Navigation 중 SV20은 국적선 중 여객선(연안/국제) 및 서비스 요청 선박을 대상으로 선내시스템 원격모니터링 서비스를 제공하여 해상 관련 정보를 실시간으로 수집하고 분석하여 해상에서 선박의 안전을 증진하기 위해 개발 중인 시스템이다. 이러한 SV20 시스템을 모든 서비스 대상 선박에 적용하기 위해서 범용화가 필요하다. 그러나 선박마다 선형, 조종성능, 각종 장비 등의 차이점이 많아 범용화가 쉽게 이루어지지 않고 있다. 본 연구에서는 현재까지 진행 중인 한국형 e-Navigation 서비스 대상 선박의 사례 연구를 통해 선박이 가지는 특성을 비교하고 분류하여, SV20 항행안전모듈 범용화 방안을 제시한다.

자율운항선박, 무인선과 같이 전통적 선박 형태에 자율성이 부여되는 형태로의 발전과 함께 드론, 비행체 같은 비행 형태까지 포함하는 해상 모빌리티는 기존 통신 체계 대비 실시간성 향상 및 대용량 데이터 교환이 요구되는 새로운 해상 안전 운항 체계가 수반되어야 한다. 초고속해상무선통신망(LTE-Maritime) 송수신기를 장착한 국내 선박의 경우, LTE급의 통신 서비스를 연안 최대 100km까지 받을 수 있지만, 국제 항해를 하는 국적선과 외국적 선박을 포함하는 해상 모빌리티 안전 운항 체계 구축을 위해서는 VDES(VHF Data Exchange System)와 같은 국제협약에서 인정하고 해상이동서비스(Maritime Mobile Service)에 속하면서 기존보다 빠른 통신망의 보급이 필수적이다. 본 논문에서는 향후 해상 모빌리티 구현을 위해 필요한 해상무선통신망의 하나로 VDES의 필요성에 주목하여 그간의 개발 현황으로부터 향후 VDES 서비스 도입 및 활용방안에 관해 논한다.

최근 IMO에서는 온실가스 배출을 규제화 하고자 하는 동향이 있으며 조만간 선박에서 온실가스 배출의 규제가 실현될 것으로 예상된다. 선박에서 배출되는 온실가스는 CO$_2$가 대부분을 차지하고 있으며 세계경제상황에 따른 영향이 고려되지만 지속적으로 증가추세에 있는 CO$_2$를 감소시키기 위한 아국의 대처방안이 필요한 시점이다. 또한 향후 발효될 EEDI를 소개하고 결과적으로 GHG를 저감시키기 위한 방안인 선형개선, 폐열회수시스템, 친환경연료사용기관, SEMP 등에 관한 내용을 다루어 보았다. 이 보고서에서는 GHG를 비롯한 NOx, SOx 및 PM과 같은 유해배출물질을 Top Down방식으로 평가함으로써 선박에서 기인하는 대기오염물질 관련 국내정책 및 해운산업의 장기적인 발전전략에 유용하게 사용될 것으로 기대한다.

This is a study for international competitiveness analysis if korea ship management service using the collected data from the fields in industry. making a comparison if ship management company between domestic ones in Korea and mutinational ones in international market is more suitable for it's purpose. but competitiveness level of korean ship management companies are too low to compare. Therefore in this study, ship management devision in Korea overseas shipping companies are selected as a target of camparision and the representative of Korea ship management industry. The analysis of competitiveness is divided by price competition and non-price competition. The former is consist of element likes as crew management cost, dry-docking cost, repair cos, stores & spares cost, lubricants cost and management free cost, The later os consist of element like as quality of sea & shore personnel, efficiency of company's organization, ability of management system. qualifications & certifications, know -hoe for the ship management, structure of control & support ship and office automation & IT system. According to this analysis the ship management division in korean shipping companied are superior to the foreign specialized ship management companies generally. So, it is necessary that korea ship management industry attempt level-up continously and expand into international ship management market positively.
