Voyage data recorders (VDR) collect the ship’s sensor inputs to provide valuable information in the aftermath of an incident in the marine environment. They are basically black boxes designed to identify the cause of marine accidents and contribute to their prevention.
VDRs and S-VDRs can be fitted to all ships with 3000 gross tons or more constructed on or after 1 July 2002. A http://www.digitaldealdataroom.info/database-access-control-best-practices VDR/SVDR is a electronic storage medium that is tamperproof that is enclosed in a capsule that is that is able to withstand the pressures and shocks associated with a marine accident such as collision, fire or sinking.
The system is designed for collecting data from a variety of sensors aboard a vessel, digitizing and compressing it before storing it into the form of a secure storage unit, which is mounted externally. The tamperproof container is built to withstand the most severe heat, shock, and impact as well as pressures that could be encountered during a maritime accident, for example, a collision or a fire.
Members may want to consider upgrading their VDR/S-VDR systems to enable them to store data for longer durations. In the moment, the IMO performance standard only requires the VDR/S-VDR to store data for a maximum of 12 hours after the incident before it is overwritten.
A growing number of manufacturers offer a MantaDigital S-VDR that is able to be accessed from a distance like the way airlines’ FDR data are analyzed after an incident. This enables technical issues onboard to be detected remotely, and assists in the execution of proactive maintenance processes. Regular shoreside playbacks help bridge teams in analyzing trends in their performance and identifying opportunities for improvement.
