A ship propulsion thruster platform which is used by safety sailing takes charge of remote control of a main engine in ship. This system not only guarantees safety and reliable flight sailing but also require remote control technology of a ship. Accordingly, in this paper it deals with a telegraph lever control unit system which is a part of propulsion thruster system as localization technology. Also it makes sure of knowledge and core technology through analysis and designing and developing a telegraph lever control unit system. Moreover, it is sure of acquisition of base technology for integration of a ship propulsion thruster platform.

선박에 본격적으로 자동화시스템이 채용되게 된 것은 1960년대의 일로서 주기관을 Bridge에서 직접 제어하는 방식을 채용하고 기관실에도 Control Room을 만들어 주기 및 보기등의 원격제어와 집중감시를 Control Console에서 가능하도록 하게 함으로써 발전하기 시작하였다. 세계무역량의 증가로 인한 선복량의 증가와 선원의 부족현상은 선박에도 고도의 자동화를 요구하게 되었고 선진조선국들은 선박자동화의 기술개발에 힘써 현재에는 각국의 선급협회들도 모두 기관실무인화에 관한 규격을 제정하여 이에 합격한 선박에 대해서는 부호들을 붙여주고 있다. 이와같이 기관실무인화는 자동화기술을 집대성한 것이라고 말할 수 있지만 최근에는 기술적으로 더욱 1보 전진하여 선박에 Computer를 탑재하고 기관의 자동화뿐만 아니라 항법과 선체 및 의장계통에까지 광범위하게 응용하기에 이르렀으며 실험단계를 거쳐 세계각국에서 실적선들이 출현하게 되었다.

As the fourth industrial revolution (Industry 4.0) evolves, studies on autonomous ships have been conducting in the shipping industry. Currently, two or three degrees of autonomous ships is in operation, and a shore remote control of icer (SRCO) monitors vessel operations and intervenes remotely where necessary in the service. However, as the curriculum for an SRCO has not been established internationally, the risk of an accident by an unqualified SRCO is increasing. In this study, specifies the curriculum required for SRCO that consists of suitable existing training and new training under remote control circumstances. This includes Non-technical skill training to enhance the effectiveness of an SRCO. This curriculum can be used for a new SRCO to evaluate training and competency specific safety standards, and to enable existing seafarers to become SRCOs through the necessary training.

With the technological innovation owing to the 4th industrial revolution, the maritime transportation is rapidly being developed with autonomous ships and systems. Particularly, autonomous ships will partially replace the manned ships and navigation among them remotely upon the degree of autonomy suggested by IMO. Accordingly, the remote operator and related research have increased as well. However, the data on the minimum required manpower for remote operators are lacking such as considering engage required situations and their co-occurrence probability. Therefore, this study proposes a simulation model that calculates the number of remote engage required situations by defining restricted water area and remote engage required situation as close-quarter situations based on accumulated trajectory data of actual ships. The findings are expected to be used as background materials to establish the appropriate manpower distribution of remote operators in remote operation centers.

Maritime Autonomous Surface ships(MASS) are gradually gaining importance. Until fully autonomous ships are developed, they will likely be controlled by remote operators who are based in a Remote Operations Center. However, there is currently no internationally or domestically established licensing for them. This issue can potentially pose a risk to navigation safety due to operations being handled by unqualified remote operators. We conducted a literature review and proposed criteria for the adoption of a licensing system for remote operators. We have futher offered alternatives to integrate this license into the existing officer licensing system, and analyzed them using Analytic Hierarchy Process(AHP). Subsequently,, theprimary need to enact legislation for remote operators is observed. The most preferred approach is to include the occupation of a remote operator in the Ship Officer Act, Article 4: Occupational Categories and Class of Licenses. Therefore, it would be logical for the organizational structure of the Remote Operation Center to mirror the traditional Bridge Resource Management. This study will contribute to the efficient training of remote operators and the safe navigation of autonomous ships with a focus on human resource management.

This paper describes development of distributed type independent electro-hydraulic ballast valve remote control system with diagnostic function based on fuzzy inference using redundant Modbus communication and ethernet Modbus TCP/IP. Diagnostic function estimate degradation of system components and diagnose system faults, which results in shortage of fault maintenance time and improvement of system safety. Slave devices which control each valve and master device which command, monitor and diagnose slave system are developed. Slave devices are connected to master device with redundant Modbus networks and master device is connected to ship's integrated control system with Modbus TCP/IP. Also this paper describes development of simulator to test and confirm whether developed system can be integrated with ship's integrated control and monitoring system.

본 연구에서는 자율운항선박의 원격 관제 및 제어하는 과정에서 원격 운항자에게 사전 충돌 위험 정보를 제공하기 위해 선박자동식별시스템(AIS, Automatic Identification System)의 항적 정보를 토대로 자율운항선박의 운항 경로 상에 잠재된 충돌 위험 영역을 예측하기 위한 기초 연구를 수행하였다. 자율운항선박의 운항 경로 상에 근접한 타선의 AIS 정보에는 기본적으로 선박의 위치, 속도, 침로에 대한 정보가 반영되어 있으므로, 이러한 정보를 토대로 일정 시간 동안 운항 경로를 예측할 수 있다. 그리고 예측한 정보를 기반으로 대표적 충돌 위험 지수인 최근접점(CPA, Closest Point of Approach)과 최근접점 거리(DCPA, Distance to CPA) 정보를 활용하여 충돌 위험 영역을 2차원 공간상에서 예측하였다. 제안된 방법은 실제 AIS 항적 데이터를 활용한 수치 시뮬레이션을 수행하여 초기 결과를 검증하였다.
