The VDR (Voyage Data Recorder), is www.digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ the maritime version of the black box that is used by airlines. The system is typically two-part in that it is a data collecting unit connected to a protective capsule on deck designed to withstand fire, deep-sea pressure and shock, as well as penetration. It is used to record incidents of navigation, but it can also provide valuable data to analyze damage from heavy weather monitoring performance and crew training.
Up-grading
Many ships with VDR/SVDR meet the minimum requirements of regulatory compliance. However, Members are encouraged use the equipment to record near accidents, conduct incident investigations and for preventive maintenance. There are also software which can extend the period during which VDR data is available beyond the minimum of 12 hours. It is important to make a decision made on whether to upgrade the equipment.
The system is built on an industrial-grade computer that performs several functions, including processing and encoding information received from sensors. The data is then stored in a capsule designed to withstand an accident and provide proof of what happened onboard the ship. The VDR system is made up of an data collection device situated on the bridge, as in addition to a dedicated power supply as well as an interface unit and backup batteries. The unit collects data from all integrated sources such as microphones that record bridge audio, and sends it to the Concentrator. Here, it is processed into a series of NMEA 0183 sentences are read and encoded prior to being transmitted to the final recording medium.
