The VDR (Voyage Data Recorder), is the maritime equivalent to the black box used by airlines. The system is usually two-part in that it is an information-collecting unit that is connected to a capsule that is deck-mounted designed to withstand https://digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ fire, deep-sea pressure, shock and penetration. It is typically used to record incidents during navigation, but also provides useful data for analysis of heavy weather damage and performance monitoring as well as training for crew members.
Up-grading
Many ships fitted with VDR/SVDR technology meet the minimum requirements of regulatory compliance however, Members are urged to think about using the equipment for incident investigation, preventive maintenance and bridge team training, as well as for recording near misses. Additionally, there are software options that could significantly extend the period of duration for which VDR data is available from the current minimum of 12 hours and a decision should be made about whether or not to upgrade to this.
The system is constructed around an industrial computer that carries out various functions, including processing and encoding the data received from the sensors. The capsule is designed to withstand any incident and also store the data. The main components of the VDR system comprise a data collection unit that is located on the bridge, a dedicated power source along with an interface unit as well as batteries for backup. The unit gathers data from all integrated sources, including microphones to record bridge audio, and sends it to the Concentrator where the resulting NMEA 0183 sentences is interpreted and encoded for transmission to the final recorded medium.
