Voyage data recorders (VDR) collect the ship’s sensor data to provide valuable insight in the aftermath of a marine incident. They are basically black boxes for the maritime industry, designed to determine the cause of a marine accident and contribute to prevention.
VDRs and S-VDRs are affixed to all ships with at least 3,000 gross tons and up that were built on or after 1 July 2002. A VDR/SVDR is a storage medium that can endure pressures and shocks from marine events like sinking, collision, or fire.
The system is designed to gather information from a variety of shipboard sensors, digitize it and compress it before storing it in a protective externally mounted storage unit. The tamperproof container is built to withstand extreme heat, shock and impact, as well as pressures, that may be encountered during a maritime incident, such a collision or fire.
Members may wish to upgrade their http://www.digitaldealdataroom.info/ VDR/SVDR system so that they can retain information for a longer time. At present, IMO performance standards only require that VDR/SVDRs keep data for 12 hours after an incident.
A growing number of companies are now offering a ‘MantaDigital’ S-VDR that can be accessed remotely in the same way that airlines’ FDR data is analyzed after an incident. This allows remote detection of technical issues onboard and helps implement proactive maintenance procedures. Regular shoreside playbacks also assist bridge teams in analyzing trends in their performance and identifying improvements.
