The vdr system is a recording device which in turn records data from on side sensors and devices. For instance radar, nav instruments and many others and then compresses these details into a single stream that is sent to the apparent FRM or final documenting medium.
The recording process is normally supervised by bridge workforce to ensure that all of the relevant info is documented correctly. This way the ship’s safety and integrity can be protected.
JOURNEY DATA RECORDER SECURITY AND DIGITAL FORENSICS
The VDR is a laptop which is ready of automatically preserving and recording info from on side devices and sensors. This can range from the ship’s what is the purpose of a data audit navigational tools, weather radio station and traditional acoustic monitoring products.
It is also able to record information from other types of note of equipment such as the EPIRB as well as ships’ conversation systems. These data are highly processed and kept within the computer before being delivered to the apparent FRM or perhaps final record medium, which is an industrial grade pc that allows data via all onboard sensors.
During an event the data by various sources is definitely fed in the computer that then collects it and saves it for a length of at least 12 hours just before it is overwritten. This means that if there is an accident and the crew shoves the save button it will be possible meant for the crew to find the evidence of the accident, enabling these to get on with the rescue experditions.
It is recommended that the saving of VDR/S-VDR data should be practised during emergency drills, consequently the fact that the bridge workforce becomes knowledgeable about the operation of the appliances. It is also advised that the vessel’s safety management should contain a section means save your data for securing of evidence in the event of an accident.
