VDR (Voyage Data Recorder) is the maritime version of the black box airlines use. It is typically made up of two parts comprised of a data-collection device and a deck-mounted protective pod designed to withstand shock as well as fire, deep-sea pressing, and penetration. It is used to document incidents of navigation, but it can also provide valuable information to analyze damage from heavy weather as well as performance monitoring and crew training.
Up-grading
Many ships with VDR/SVDR comply with the minimum requirements of regulatory compliance. However, members are encouraged to use the equipment to document near misses, conduct incident investigations and to conduct preventative maintenance. In addition, there are applications that can extend the duration for which VDR information is available, starting from the current minimum of 12 hours and a decision should be made as to whether or not to upgrade to this.
The system is built on an industrial grade computer that performs various functions, including processing and encoding data received from sensors. The data is then stored inside a capsule designed to survive an accident and provide evidence of what transpired on the ship. The primary components of the VDR system include a data collection unit that is located on the bridge, a separate power source as well as an interface unit and batteries for backup. The unit collects all information from integrated https://digitaldealdataroom.info/learn-how-much-should-a-data-room-cost-in-reality/ sources such as microphones for recording bridge audio, and then sends it to a Concentrator, where a sequence of NMEA 0183 sentence is processed and coded to be sent to the final recording media.
