The vdr system is a recording device which in turn records info from on side sensors and devices. For instance radar, routing instruments etc and then compresses this info into a single stream that is sent to the so-called FRM or perhaps final documenting medium.
The recording process is normally supervised by bridge team to ensure that most relevant data is registered correctly. This way the ship’s safety and integrity is certainly protected.
TRIP DATA RECORDER SECURITY AND DIGITAL FORENSICS
The VDR is a computer system which is equipped of quickly preserving and recording info from on side devices and sensors. This can range from the ship’s navigational devices, weather rail station and audio monitoring equipment.
It is also capable to record data from other types of on-ship equipment including the EPIRB or the ships’ connection systems. These info are refined and placed within the pc before being brought to the alleged FRM or final record medium, which can be an professional grade laptop that allows data out of all on-ship sensors.
During an incident the data via various sources is fed in the computer that then gathers it and saves it for a amount of at least 12 hours ahead of it is overwritten. This means that if you have an accident as well as the crew catapults the save press button it will be possible pertaining to the team to find the evidence of the accident, enabling them to get on with the rescue surgical procedures.
It is recommended that the saving of VDR/S-VDR data should be practised during urgent drills, thus vdr system that bridge group becomes knowledgeable about the operation of the apparatus. It is also suggested that the vessel’s safety management system should contain a section for you to save the information for obtaining of facts in the event of your accident.
