VDR (Voyage Data Recorder) is the maritime equivalent of the black box airlines employ. The system is usually two-parts, consisting a data-collection unit and a deck-mounted safety pod designed to withstand shock as well as fire, deep-sea pressing, and www.digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ penetration. It’s used to record events that occur during navigation, but it can also provide valuable information for heavy-weather damage analysis, performance monitoring and crew training.
Up-grading
Many ships fitted with VDR/SVDR devices meet the minimum requirements of regulatory compliance however, Members are urged to think about using the equipment to investigate incidents as well as preventive maintenance and bridge team training as well as to record near misses. There are also software options that could significantly extend the period of time for which VDR data is available beyond the current minimum of 12 hours and a decision should be made about whether or not to upgrade to this.
The system is based on an industrial-grade computer that performs several functions, including processing and encoding information received from sensors. The capsule is designed to withstand any disaster and keep the data. The major components of the VDR system include a collection unit that is located on the bridge, a separate power source, an interface unit and backup batteries. The unit collects all data from the integrated sources, including microphones to record bridge audio, and then sends it to a Concentrator which is where a string of NMEA 0183 sentence is interpreted and encoded before being sent to the final recorded media.
