The development of remote maintenance technology based on Voyage Data Recorder

This paper introduces a remote maintenance technology based on VDR(Voyage Data Recorder) which is capable of diagnosing the status of navigational equipment and monitoring the navigational information from a remote place via satellite communications. Firstly we implemented the messaging library complied with Ethernet-based IEC 61162-450 standard which integrates intra-ship equipment, such as VDR, AMS(Alarm Monitoring System), and BMS(Bridge Maneuvering System) into one unified network. Secondly we developed a remote maintenance application which applies the messaging. This application performs the functions which are transferring of real-time navigation data, navigation data on specific time, system status and log, and captured images. Consequently, we secured the technology of ship remote maintenance using VDR in this paper.
