For the efficient and safe navigation management of ships cruising across oceans, international maritime law environments have been reinforced and the demand of information sharing between ships and shore has also been increasing. According to these environments and demand. researches about digital ships, ship integration, and ship integration networks have been active recently in US and Europe. In this raper, we first investigate about the proper ship integration platform, and then design and implement a ship integration network based upon the ship integration platform. We construct networks connecting various devices and systems into a layered architecture, and design an integration protocols. Based upon this architecture and protocols, we implement an ship integration system which manages all data and information of ship in a standardized platform and support ship-shore information sharing through which the more efficient and safer ship navigation management are supported with help from shore. We test our ship integration system by applying it to real operating ships and we find our system reliability and verify the efficiency of ship-shore information sharing and management.

최근 지능형 선박(Smart Ship)에 탑재되는 정보화 장비의 종류 및 수량이 증가하고 있는 조선 산업계 동향에도 불구하고, 이들 장비를 효율적으로 통합하고 제어할 수 있는 선박의 백본 네트워크에 대한 연구는 미흡한 실정이다. 따라서 본 논문에서는 지능형 선박의 특수성을 고려한 백본 네트워크로, 네트워크 생존성과 트래픽 효율성 측면에서 최적 성능을 나타내는 선박 통신시스템(SAN : Ship Area Network)을 설계하고자 한다. 이를 위해 지능형 선박에 설치되는 이중화 네트워크 토폴로지 및 이를 효율적으로 운용하는 통신 프로토콜에 대한 연구를 수행하였다. 또한 제안한 선박 통신 시스템의 최적 성능을 그래프 이론, 시뮬레이션, 그리고 구현 명세 등을 포함한 체계적이고 실증적인 분석을 통해 검증하였다.

자율운항선박의 도입을 위해서는 선박 항해 장비 및 시스템들에 대한 국제표준화가 필수적이며, 선박의 항해 및 무선통신 장비들에 대한 표준을 제정하는 국제전기연합(IEC)의 표준화 활동은 매우 중요하다. 본 논문에서는 자율운항선박에서 다루게 될 수 있는 사이버보안 표준을 비롯하여 선박 장비 및 시스템에 대한 표준현황을 다루고 있다. 또한, 해사서비스의 디지털화를 위한 고려요소인 해사공통정보모델과 이를 위한 이내비게이션 서비스 표준 동향도 다루고 있다.

Thus, all systems and sensors corresponding to navigation are integrated to an INS (Integrated Navigation System) or an IBS (Integrated Bridge System). Propulsion automation systems, propulsion systems, auxiliary systems, and power management systems are integrated to an ICMS (Integrated Control and Monitoring System), an IPMS (Integrated Platform Management System), and IMCS (Integrated Monitoring and Control System). This paper introduces the results of designing and implementing an Integrated Interface System which ties up diverse system interfaces via network and inversely converts network signals into a proper interface signal type connected to other systems.

In the shipbuilding industry, due to the global trends where the number of IT (Information Technology) devices of a smart ship have been increased rapidly, the need to develop a new shipboard backbone network has recently emerged for integrating and managing the IT devices of a smart ship efficiently. A shipboard backbone network requires high survivability because it is constructed in automatic and unmanned smart ships where a failure of the backbone network can cause critical problems. The purpose of this paper thus is to study SAN (Ship Area Network) as a efficient shipboard backbone network, considering particularity of shipboard environment and requirement of high survivability. In order to do so, we designed a dual network topology that all network nodes, including the IT devices installed in a smart ship, are connected each other through dual paths, and reuding tht IT devices pnstalles supporices network survivability as well as t Iffic efficiency for the dual network topology. And then, we verified the performance of the suggested SAN by theoretical and practical analysis including the graph theory, the probability theory, implemental specifications, and computer simulations.

Recently, the on-board equipments of vessels are getting diversifications with high technologies. With changing the trends, the shipboard network is turning to the light-weight ethernet architecture for integrated data management. For that necessity, this paper covers a development of the gateway system which gathers and processes the measured analog or NMEA data from loaded equipments to convert the messages based on IEC 61162-450 (standard for light-weight ethernet network of ships) in engine parts of small vessel. To do this, we analyzed the requirements for standardization of ship's equipments and related studies. To solve the problems of existing equipments, we defined the additional data formats (sentence formatter), developed the gateway system, and verified the utility of the developed system. Consequently, we established an interfacing framework for management and application of the generated data based on the ethernet in vessel.
