Voyage data recorders

A voyage data recorder (VDR), often known as the ship’s ‘black box’, collects and stores information over the course of a ship’s journey, including:

  • the ship’s position
  • audio from the ship’s bridge
  • the ship’s speed and heading
  • depth under the keel
  • VHF radio communications

All VDRs must be tested after installation and then inspected every year.
