Voyage Data Recorders (VDR)

Published in 20 de janeiro de 2024 by

Voyage data recorders (VDR) collect data from ships, process and store sensor data to give valuable insights in the aftermath of an incident on the water. They are basically black boxes that are designed to determine the causes of marine accidents and contribute to their prevention.

VDRs and SVDRs must be installed on all ships with a gross capacity of 3,000 or more that was built after July 1, 2002. A VDR/S-VDR is a electronic storage medium that is tamperproof encased in a capsule capable of enduring the shock and pressures associated to a marine event such as collision, fire or sinking.

The system is designed to collect data from various sensors aboard a vessel, digitizing and compressing it before storing it in a protective storage unit mounted externally. The tamperproof container is built to withstand extreme heat, shock and impact as well as pressures that might be encountered during a maritime incident, such a collision or fire.

Members may wish to upgrade their VDR/SVDR system so that they can retain data for a longer period. Presently, IMO performance standards only require that VDR/SVDRs keep data for 12 hours following an incident.

A growing number of companies offer a MantaDigital S-VDR which can be accessed from a distance similar to the way airlines’ FDR data are analyzed after an incident. This allows technical issues onboard to be identified remotely, and assists in the execution of proactive maintenance processes. Regular shore-side replays help bridge teams to identify trends in their performance, and identify improvement opportunities.
