The VDR System – Health and safety and Digital Forensics

The vdr system is a recording device which in turn records info from aboard sensors and devices. This can include radar, nav instruments and so on and then compresses this information into a single stream that is sent to the so-called FRM or perhaps final saving medium.

The recording process is supervised by bridge workforce to ensure that all relevant data is registered correctly. This way the ship’s safety and integrity is definitely protected.


The VDR is a laptop which is have the ability of instantly preserving and recording data from aboard devices and sensors. This can include the ship’s navigational machines, weather radio station and traditional acoustic monitoring units.

It is also capable of record information from other types of on-ship equipment such as the EPIRB and also the ships’ communication systems. These data are highly processed and placed within the pc before being sent to the apparent FRM or final record medium, which is an commercial grade pc that welcomes data via all onboard sensors.

During an incident the data from various sources is usually fed in to the computer that then gathers it and saves that for a period of at least 12 hours just before it is overwritten. This means that if there is an accident and the crew catapults the save press button it will be possible intended for the staff to find the evidence of the mishap, enabling them to get on with the rescue operations.

It is recommended that the saving of VDR/S-VDR data should be practised during crisis drills, and so the fact that bridge crew becomes knowledgeable about the procedure of the devices. It is also recommended that the vessel’s safety management should contain a section in order to save the data for safe-guarding of data in the event of an accident.
