Voyage Data Recorders (VDR)
Voyage data recorders (VDR) collect, process and store shipboard sensor inputs to provide valuable information in the aftermath of an incident at sea. They are essentially black boxes for the maritime industry, designed to pinpoint the root of a marine accident and contribute to prevention.
VDRs and SVDRs are required to be installed on all vessels that have a gross tonnage of 3,000 or greater and built after July 1st, 2002. A VDR/SVDR is a storage device that can withstand shocks and pressures from incidents in the marine environment, such as sinking, collision, or fire.
The system is designed to gather data from various shipboard sensors, and then digitize and compress it, and then store it in a secure externally mounted storage unit. The tamperproof storage container is designed to withstand the most severe shock, impact and heat, as well as pressures that can be encountered in a marine incident, like a collision or fire.
Members may wish to upgrade their VDR/SVDR systems to ensure that they can store information for a longer time. In the moment, IMO http://www.digitaldealdataroom.info/how-to-get-started-with-your-new-ideals-vdr-system performance standards only require that the VDR/SVDR be kept in data for 12 hours following an incident.
A growing number of manufacturers now offer a ‘MantaDigital’ S-VDR that is able to be accessed remotely in the same way airlines’ FDR data is analyzed after an incident. This enables onboard technical issues to be diagnosed remotely and facilitates the implementation of proactive maintenance procedures. Regular shore-side playbacks also support bridge teams in understanding the trends in their performance and identifying improvements.
