The vdr system is a recording click to investigate device which will records data from aboard sensors and devices. This consists of radar, map-reading instruments and so forth and then compresses this information into a single stream that is transmitted to the apparent FRM or final documenting medium.

The recording process is usually supervised by bridge staff to ensure that each and every one relevant info is documented correctly. This way the ship’s safety and integrity is definitely protected.


The VDR is a computer system which is able of quickly preserving and recording info from aboard devices and sensors. This can are the ship’s navigational accessories, weather stop and traditional acoustic monitoring devices.

It is also in a position to record facts from other types of on-ship equipment including the EPIRB or perhaps the ships’ communication systems. These data are prepared and stored within the laptop before being sent to the so-called FRM or final record medium, which is an commercial grade computer system that accepts data right from all note of sensors.

During an incident the data from various sources can be fed in to the computer that then collects it and saves that for a amount of at least 12 hours just before it is overwritten. This means that if you have an accident as well as the crew shoves the save option it will be possible intended for the crew to find the proof of the crash, enabling these to get on with the rescue functions.

It is recommended that the saving of VDR/S-VDR info should be performed during crisis drills, hence the fact that bridge group becomes acquainted with the operation of the apparatus. It is also suggested that the vessel’s safety management system should contain a section on how to save the info for securing of research in the event of the accident.
