Various countries around the world are conducting various studies to apply information and communication technology to marine safety. Based on this, the International Maritime Organization (IMO) has established the e-Navigation standard to apply the latest information and communication technology to marine services. In Korea, the Ministry of Maritime Affairs and Fisheries is promoting Korean e-navigation considering domestic marine environment and is trying to apply LTE communication method as a high-speed wireless communication method at sea. In this paper, we describe the development of an LTE based marine router system supporting 700Mhz frequency band allocated for high speed maritime wireless communication service. Experiments on the possibility of 100km distance communication from base station using LTE based ship router are shown. LTE - based high - speed maritime wireless communication router system can provide communication infrastructure necessary to develop various accident prevention technologies that may occur at sea.

In this study, safety management procedures were developed based on domestic and foreign guidelines and related maritime law to ensure the safe development and implementation of smart autonomous ship technology and Samsung Heavy Industry. The safety management procedure was developed according to the guidelines for (MASS) sea trials (MSC.1/Circ.1604, Annex: Interim guidelines for MASS trials), proposed by International Maritime Organization (IMO) for the relevant authorities and stakeholders of MASS to properly conduct tests of systems and infrastructure related to safety and environmental protection. The developed safety management procedure applies to the maritime demonstration test of a system applying autonomous navigation element technology mounted as a navigation aid on a ship operating under a watch system, while complying with the environmental protection and navigation safety of the coast of Korea.

It was recommended for all ship engaged in international voyages to carry the dedicated Digital Selective Calling receiver, DSC equipment, VHF transceiver, etc according to Global Maritime Distress & Safety System. Also International Maritime Organization recommended for navigation and communication equipments to applicate the EMC regulations, therefore most of electronic equipments using in the vessel to be faced with problems to cope with new regulations. This study has applied and analyzed the EMC for an equipment integrated with Ch.70 dedicated DSC receiver, DSC equipment, VHF transceiver and groped for solutions to cope with. The test has applied the electromagnetic interference such as the measurement for unwanted emissions from conductive & radio emission and the electromagnetic susceptibility such as the immunity from voltage, frequency variation and electro static discharge, hence comes to be understand the problems related with the power and the earth.

1990년대 말부터 IMO(International Maritime Organization)의 SOLAS(Safety of Life at Sea) 조약에 따라 300톤 이상의 모든 선박에 GMDSS(Global Maritime Distress & Safety System)를 탑재함으로써 전 세계 어디에서나 선박의 조난 및 안전 통신을 위한 육 해상 통합시스템의 기틀이 마련되었다. 최근에는 GMDSS의 현대화와 e-Navigation 개발전략에 따라 해상통신 기술의 디지털화와 음성에서 데이터 통신으로의 큰 변화가 예상된다. 이에 GMDSS 중심의 해상통신 기술현황을 위성, MF(Medium Frequency), HF(High Frequency), VHF(Very High Frequency) 등 다양한 통신 기술에 따라 설명하고 e-Navigation 개발전략에 따라 해상통신 기술의 발전 방향을 살펴보도록 한다.

Today, all the countries of the world newly recognize importance of sea on 70% area of the earth, which are focused on efforts for security of marine territory and fishes resources. On the security concerns of the ocean & fishes resources, Sea are very important on the ground of the importance of the ocean, thus international community has been trying to combat a maritime security threat and illegal fisheries. Coastal states need to have proper state's jurisdiction and exercise it's jurisdiction to response effectively to a maritime security threat and illegal fisheries. Here, many of the coastal states strengthened the rights in Exclusive Economic Zone(;EEZ) naturally, there are made cooperation activities and keen competition in the sea because deepening of complex understanding of the relationship between the surrounding countries with marine surveys & continental shelf development, island territorial sovereignty & marine jurisdiction in overlap of sea area on EEZ. In these circumstances, foreign fishing boats invaded to our territorial waters and EEZ many times. in addition, Chinese fishing boats are going to illegal fisheries naturally. On this point, a powerful crackdown of maritime enforcement organization had no effect on them. Also more and more their resistance gathered strength and tendency of a illegal activities became systematization, group action and atrocity little by little. So this thesis includes a study on the regal regulation, the system and formalities on the control of illegal fishing. And the author analyzed the details of the activities of illegal fishing and boats controlled by Korea Coast Guard(KCG), fishing patrol vessels of Ministry of Maritime Affaires and Fisheries(MOMAF) and Navy etc. from in adjacent sea area of Korea. In relation to this, the policy and activity plan were devised to crackdown to illegal fisheries of foreign fishing boats and then it was enforced every year. According to this, analyze the present conditions of illegal fisheries of a foreign fishing boats on this study, also analyze the present conditions of maritime enforcement organization & found out problems to compared it. protect the territorial waters, at the same time protection of marine mineral resources & fishes resources of EEZ including continental shelf, which has want to study for the role & response of maritime enforcement organization for the protection of fisheries resources and a proper, a realistic confrontation plan of maritime enforcement organization against illegal fisheries of foreign fishing boats.

This paper presents recent trends of technology and standardization for modernizing maritime mobile radiocommunication. International standard organizations are studying for digitally global maritime mobile radiocommunication infrastructure that harmonized frequency allocations and technical regulations internationally. ITU-R develops regulations, recommendations and reports by cooperating with IMO and IEC. This paper analysed reports which is from several meetings(WRC-12, ITU-R WP5B) to held recently between these organizations.

The International Maritime Organization (IMO) has defined e-Navigation for the purpose of providing safe and efficient maritime information and communication services. Currently, a maritime cloud is being developed as a communication infrastructure for e-Navigation services. In this paper, we design the structure of vessel ID importation system which can efficiently register the maritime ID in the maritime cloud environment.

Bans on TBT based antifouling paints have been drafted since 1998 by meetings 42, 43, 45 and 46 for the MEPC(Marine Environmental Protection Committee) of the international Maritime Organization, and decided finally at a Diplomatic Conference of the IMO in October 2001. It was a key issue that there should be a global prohibition on the presence of organo-tin compounds in ships by 1 Jan. 2008. TBT Paint Wastes from ship have been produced by vast quantity since 2003. This paper suggests a method to design Treatment System for TBT Paint Waste from Ship. The organotion compound was dissolved by heating, and the organic matters was oxidized and turned into inorganotins, then they were stabilized in the end. At 500^{\circ}C$, the organotin compound which heated for one hour was removed by 58%, and in 1000^{\circ}C$ the organotin compound was treated by 99.9% after and hour of heating treatment.
