We show a new scheme and implementation of maritime data communication systems for GMDSS ship which performs e-Navigation and removes the functional limitation of those systems through comparing to service fee, call processing reliability, and bit rates of all of those systems within communication range at sea. We confirmed available each frequency band communication and application services at sea by experimental result with proposed new system, MF/HF band being useful to a short text message service, VHF band to 9600bps email service, Fleet Broadband Maritime Satellite system to one or more Mbps multimedia service each.

The transportation of oil has increased due to the growth of marine industries and oil refineries. Oil residues and waste discharged to the ocean has increased due to accidental and/or intentional discharges. The International Marine Organization(IMO) has made compulsory that every oil tanker of 150 gross tonnage and above and every ship of 400 gross tonnages other than tankers and above should be provided with an oil record book. The entries in the oil record book should be made in accordance with the IMO guidelines. Specifically, engine room generated oil residues should be recorded in the oil record book from January 1, 2011. Also, the developed IMO guideline should be added for the prevention of dispute with the Port State Control Officers and(or) Tanker Vetting Inspectors. This oil record book will be in operation and of valued assistance to the marine officers, according to the IMO policy for the prevention of the waste oil and the oil mixtures from the machinery space. For the convenience, added Code & Item No. list, FAQs and reviewed and revised Examples.

어선 안전에 관한 최초의 국제 협약인 1977 어선안전을 위한 토레몰리노스 국제협약(77 협약)을 대체한 1993 토레몰리노스 의정서(93 의정서)는 현재 그 발효요건이 충족되지 못하여 전 세계적으로 발효되지 못하고 있는 실정이다. 이에 국제해사기구(IMO)는 93 의정서의 요건을 완화하여 각 국의 비준을 촉진시킬 목적으로 "1993 토레몰리노스 의정서 시행에 관한 협정"의개발을 해당 전문위원회인 복원성, 만재흘수선, 어선안전 전문위원회의 우선과제로 추진하고 있고, 제53차 회의(SLF 53, 2011. 1월)까지 동 협정 또는 총회결의의 초안 작업을 완료하여, 최종적으로 제27차 IMO 총회(2011. 11월)에서 이를 채택할 계획으로 논의를 진행하고 있다. 따라서 이러한 국제적인 움직임에 대응하고 동 의정서의 발효에 대비하여 우리나라에 미치는 파급효과를 최소화하기 위한 활동의 일환으로 공단이 수행한 "농림수산식품부의 2010년 수산기술개발사업"인 "1993 토레몰리노스 의정서 시행에 관한 협정 개발 대응연구"의 일부로써, 본 연구는 "선박안전" 제29호 및 제30호에 게재된 "1993 토레몰리노스 의정서의 시행에 관한 IMO의 활동"에 이어 최근 IMO의 회의 결과를 담고 있다.

The increasing trade volume between Korea and China has rapidly expanded the maritime transport between the two countries. However, safety, particularly considering the ship collisions in the Yellow Sea and East Sea waters, has not been fully ensured. These collision accidents in that region endanger traffic safety and the marine environment, moreover, it has the potential to cause legal complexity because Korea and China haver domestic legislation, that are considerably different in some aspects. International conventions and domestic legislation in China provide detailed laws with respect to ship collisions, however, the theory of ship collision infringement still needs to be improved, enriched, and developed. Because these laws are not very clear on the resolution of disputes resulting from ship collisions, we focused on the final judgments by the Supreme Court of China (SPC), and the judicial judgments set by the Maritime Court of China. This study aimed to explore the domestic legislation applicable to disputes related to ship collisions in China, and comparatively investigate the legal provisions of Korea and China on the issue of ship collisions, particularly on the aspect of damage compensation, fault ration, and liability apportionment.

It is necessary to use satellite radio navigation system as well as satellite radio navigation augmentation system such as differential Global Positioning System to achieve the positioning accuracy and reliability requested by International Maritime Organization in port and coastal area. Especially, position accuracy of DGPS user is effected by accuracy of pseudorange correction broadcasted from DGPS reference station. This paper shows pseudorange correction calculation algorithm adopting a non-common error estimation filter in order to improve accuracy of pseudorange correction. Finally, this paper verifies that the pseudorange correction calculated by adopting a non-common error estimation filter satisfies performance specifications of RTCM.

The results of investigations into marine incidents have become an important basis in determining not only possible causes, but also the extent of negligence between the perpetrator and victim. However, marine incidents occur under special circumstances i.e. the marine environment, and this leads to difficulties in identifying causes due to problems in scene preservation, reenactment and acquisition of witnesses. Given the aforementioned characteristic of marine incidents, the International Convention for the Safety of Life at Sea (SOLAS) has adopted mandatory regulations on the carriage of Voyage Data Recorders (VDRs) and Automatic Identification Systems (AIS) for ships of a certain gross tonnage and upwards, so as to reflect recent developments in radio communication and marine technology. Adopted to provide an international standard for investigations and to promote cooperation, the Code of the International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident (Casualty Investigation Code) recommends member states to build capacity for analysis of VDR data. Against this backdrop, this paper presents methods for efficient investigations into the causes behind marine incidents based on data analysis of VDR, which serves as the black box of ships, as well as digital forensic techniques.

A concept of the "e-Navigation" was introduced in 2005 and implementation strategies are under way by IMO/IALA in the maritime safety area. Specially VTS is an important maritime traffic monitoring and aids to navigation system which is aims to improve safety, navigation efficiency and protect the marine environment. The demand of the inter-VTS networking has been increased and standardization is underway for realization of shore side collaboration for maritime safety in IALA. But there may be security problems in the inter-VTS networks if they have not proper security mechanism. The hacking of realtime ship position and sensitive maritime surveillance information caused a critical accident of vessel, human life and environment by terrorist. This paper aims to design of a secure inter-VTS network structure and related security protocol for secure sharing of sensitive maritime data.

The international maritime organization(IMO) has defined performance requirements for future maritime navigation through IMO resolution A.915(22) in 2001. Many DGPS systems currently providing DGPS services do not meet the performance requirements specified in IMO resolution A.915(22). The use of SBAS is considered as one of the DGPS replacement and supplementary system for coping with the increase in demand performance and providing safe positioning service. In particular, since a large amount of budget is required to rearrange the existing DGPS reference stations, a method which transmits differential corrections generated by using SBAS message has been proposed. In this paper, we compare and analyze the performance of NDGPS which is operated by the National Maritime PNT Office of the ministry of oceans and fisheries(MOF) in Korea and MSAS in Japan. Also, we verify that SBAS, as alternative and complementary system, meets the performance requirement specified in IMO resolution A.915(22).

This study describes and discusses the marine accidents investigation & inquiry system of Korea, U.K., U.S.A., the Netherlands and Japan. As the results of the comparison of them, the following recommendations are made with respect to improve the system in Korea. (1) The Agency should be independent from the central Government with respect to the budged, personnel management and a agency building. (2) The inspection function and judgment function should be divided into separate Agency. (3) The Agency should has a recommendation right to Government agency according to the results of investigation. (4) The composition of inspectors & judges must be diversified including navigation, marine engineering and naval architecture background. (5) The Agency should have co-operative system with the Marine Police Agency. (6) International affairs division should be included in the Agency to promote international relations.
