The SOLAS ship should carry at least 83 different types of equipment based on the SFI group codes and each of which consists of several to dozens of components. During ship operation, it is necessary to ensure the normal operation of such equipment, and remote maintenance is highly demanded for immediate repair in the event of a equipment fault. This study proposes to find suitable classification system and to derive database structure for remote maintenance of navigation and communication equipment. As a result of this study, the classification system of equipment should be layered into equipment type, model, and component, and main table in the database consists of FMEA, service history, case data through Q&A, Preventive Maintenance. A database was constructed for 140 navigation and communication equipment models and 750 components. In order to evaluate the practical effects, service engineer evaluated the usefulness using the cloud app.

We develope the PC based SPS to improve safety at sea, save fuel and time during a voyage and makes mariner's work more efficient and comfortable in ship navigation, who propose the auto-navigation system with SPS as basic main system. Developed SPS operate the function to monitor navigational equipment and to substitute a broken main navigational equipment such as CIS, ECDIS, or Radar/ARPA, automatically. These can be improve more efficient and comfortable ship navigation and reduce these traffic accident. The SPS has the function as DB and network server, additionally.

New ship technology and trapping equipment must be implemented into ship sailing which is currently used nowadays. The day/night camera stability, user interface, track, and remote control system of Jim structure for all over the world should be competitive in the global market. The development equipment sales are losing its competitiveness edge of the existing sailing ship communications equipment due to supply to the aging of the entire system and integration of the development especially for foreign equipment competitor.

자율운항선박 개발은 해운분야의 새로운 발전 동력으로 주목 받고 있으며, 관련 기술개발에 대한 연구가 활발하다. 특히 선박과 육상 간 통신기술 기반의 정보 연결성(connectivity)은 자율운항선박의 실현에 있어 중요한 연구 분야이며, 단위기능 제공에 한정되어 있는 항해 장비 간 통신까지 포함된다. 그러나 수집되는 항해정보들을 체계적으로 분류하고, 이용 및 관리할 수 있는 선내 플랫폼(Platform) 개발에 대한 연구는 미흡하다. 본 연구는 항해장비의 연결성을 향상시키고, 원격운항과 자율운항 선박에 적용될 수 있는 항해정보관리 플랫폼의 기능 및 구조설계와 정보처리에 대한 프로세스 제안을 위한 선행연구로 항해 장비들의 취득정보를 분석하였으며, 응용서비스 및 보안관리에 필요한 정보사항과 기능을 정의하였다. 항해정보관리에 한정 하여 수집되는 정보들에 대해 분석하였으나, 선내 플랫폼 개발의 기초 연구가 될 것이다.

The maritime ICT-convergence equipment are essentially required to a type approval (TA) certification that needs environmental and functional tests, to install in vessel. The environmental test is to experiment the possession for required durabilities of the target device in maritime environment, and the functional test is to check the required functions of target equipment based on international standard. In Korea, the environmental testing facilities amount to 227 sites, but there is no functional testing facility. Because of this, we establish a function test facility for the maritime ICT-equipment. In this paper, we analyze and design the functional testing requirement and required interlocking simulators for digital interfaces and navigation communication equipment. We propose the 2-steps of functional testing procedures, which are single test and integration test, to improve the reliability of testing result. The single test is to examine own functions of the target device, and the integration test is to check harmonized operation with other navigation and communication devices.

In the maritime digital forensic part, it is very important and difficult process that analysis of data and information with vessel navigation system's binary log data for situation awareness of maritime accident. In recent years, anaysis of vessel's navigation system's trajectory information is an essential element of maritime accident investigation for vessel digital forensic process. So, we analysis of maritime navigation systems of vessel and feature of device and environments. In the future, we will research on information of ship's trajectory and movement for useful forensic service.

항해 안전을 위한 최첨단 장비의 개발은 항해업무의 감소와 항해안전에 크게 기여하고 있다. 이러한 장비 중 하나인 ECDIS(Electronic Chart Display & Information System)의 운용을 위해 개발된 ENC는 현재 전 세계적으로 제작되고 있으며 각국의 HO(Hydrographic Office)가 자국의 공인 ENC를 제작하여 종이해도의 경우와 같이 사용자에게 배포할 예정이다. ENC는 해도에 관련된 지형정보와 해당 속성정보를 포함하고 있기 때문에 항해 뿐만 아니라 기타 응용분야에도 사용이 가능하다. 이러한 필요성에 대처하기 위해 ENC 데이터를 분석하고 근간이 되는 S-57데이터의 구조, 또한 캡슐화에 사용된 ISO/IEC 8211에 관하여 소개한다. 또한 결론부에 항해 및 기타 응용분야에서의 ENC데이터 사용 가능성을 검토한다.
