When it comes to fleet management and safe navigation, the RIVER VDR is a very interesting new development. Although the VDR has been in use for some time in the maritime shipping industry, it has now been specially developed for inland navigation by Orolia Maritime, in collaboration with Radio Holland. First and foremost, this VDR black box offers invaluable assistance in the case of incidents. The play-back functionality allows an incident to be played digitally, which can be very helpful in answering questions regarding cause and effect. A demo of this system is being shown at the Radio Holland stand. The VDR is linked with the River Radar and the intercom system, among others, in order to provide an excellent image of the situation at hand. Radio Holland has added functionality to the system to allow the measurement of a ship’s performance. This enables data with information about the functioning of the ship to be sent ashore.
