VDR (Voyage Data Recorder) is the maritime equivalent of the black box that airlines use. The system typically consists of two components, consisting a data-collection unit and a deck-mounted safety pod that is designed to withstand shock or fire, deep-sea pressurized and penetration. It’s used to record navigational incidents, but it can also provide valuable information for heavy-weather damage analysis, performance monitoring and crew training.

Up-grading

Many ships with VDR/SVDR comply with the minimum requirements of regulatory compliance. However, members are encouraged use the equipment to record near misses, conduct investigation into incidents and to conduct preventative maintenance. Additionally, there are applications that can extend the amount of time that VDR data is available beyond the current 12 hour minimum and a decision must be made about whether or not to upgrade to this.

The system is built around a industrial computer that carries out various functions, including processing and encoding the data received from the sensors. The data is stored in a capsule designed to survive an accident and provide proof of what took place on the ship. The VDR system consists of an data collection device situated on the bridge as along with a separate power supply as well as an interface unit and backup batteries. The unit gathers data from all www.digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ sources integrated including microphones, which record bridge audio and transmits it to the Concentrator where a sequence of NMEA 0183 sentences is interpreted and encoded to be transmitted to the final recording medium.
