A Voyage Data Recorder (VDR) is crucial for storing navigational data during a voyage. Routine maintenance ensures data is accurately recorded and easily retrievable for investigation after an incident. Simplified VDR (SVDR) systems serve a similar purpose but with reduced functionality. Regular servicing includes testing, software updates, data retrieval checks, and ensuring all components are fully operational. VDR/SVDR maintenance guarantees compliance with maritime safety regulations, including SOLAS requirements, and ensures crucial data is available in case of an emergency. Maintaining your VDR also helps prevent system malfunctions during critical operations.
