VDR (Voyage Data Recorder) is the maritime equivalent of the black box airlines use. The system typically consists of two components comprising a data collection unit and a deck-mounted safety pod that is designed to resist shock, fire, deep-sea pressurized and penetration. It’s used to record the events of navigation, but can also provide valuable information for analysis of damage caused by heavy weather and monitoring performance as well as crew training.
Many ships with VDR/SVDR comply with the minimum requirements of regulatory compliance. However, members are encouraged use the equipment to record near missed events, conduct investigations into incidents and to conduct preventative maintenance. There are also programs that can extend the time duration during which VDR information is available beyond the current minimum of 12 hours. The decision needs to be made on whether to upgrade the equipment.
The system is built around a industrial computer that is able to https://digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ perform various functions, including processing and encoding the data received from the sensors. The data is then stored in a capsule that is designed to withstand an accident and provide proof of what transpired on the vessel. The primary components of the VDR system are a data collection unit that is located on the bridge, a dedicated power source, an interface unit and batteries for backup. The unit collects all data from integrated sources such as microphones for recording bridge audio, and then sends it to a Concentrator, where a series NMEA 0183 sentences is interpreted and encoded for transmission to the final recording media.
