What is VDR OR Voyage data recorder ? What data items must be recorded by the VDR as per IMO Resolution ?

  •  Echo sounder
  • Main alarms
  • Rudder order and response
  • Engine order and response
  • Hull openings status
  • Watertight and fire door status
  • Accelerations and hull stresses
  • Wind speed and direction
  • The additional data (any or all) shall only have to be recorded if the data are available on the bridge and the data    signals are available in NMEA0183 format.
S-VDR

Simplified Voyage Data Recorder (S-VDR), as defined by the requirements of IMO Performance Standard MSC.163(78), is a lower cost simplified version VDR for small ships with only basic ship’s data recorded. It is not required to store the same level of detailed data as a standard VDR, but nonetheless should maintain a store, in a secure and retrievable form, of information concerning the position, movement, physical status, command and control of a vessel over the period leading up to and following an incident.

Hence, the principle difference between VDR and S-VDR lays in the requirements for recording of additional data
