Standard 6-Step VDR/S-VDR Annual Performance Test Protocol
Our Class-approved technicians execute this standardized procedural workflow to ensure first-time compliance with attending Class surveyors and Indian Port State Control (PSC) inspectors:
-
Pre-Test Inspection & Power Supply Interruption Check
Verify VDR main power unit, backup battery charging circuit, and conduct mandatory 2-hour emergency power interruption test to ensure uninterrupted audio and sensor data logging.
-
Protective Capsule & Acoustic Beacon (PT9) Verification
Inspect fixed and float-free capsules for physical corrosion, verify hydro-acoustic underwater beacon signal transmission frequency (37.5 kHz) using calibrated tester, and check battery expiry.
-
Navigational Sensor Interface & Data Integrity Validation
Check serial NMEA 0183 / IEC 61162 data feeds from Gyro, Radar, ECDIS, GPS, Speed Log, Echo Sounder, AIS, Engine Telegraph, and Wind Sensor for timestamped logging continuity.
-
Bridge Audio & VHF Communications Recording Verification
Perform acoustic audio test on all bridge microphones (internal and exterior bridge wing units) and verify clear VHF transmit/receive audio playback without clipping.
-
Raw Voyage Data Extraction & Manufacturer Log Playback
Extract 12-hour raw voyage recording sample using certified OEM service tool; analyze playback file for sentence drops, corrupted packets, or sensor communication failures.
-
Class Society Certificate of Compliance & APT Documentation
Issue manufacturer-approved Annual Performance Test Report (APTR), endorse vessel survey records, and submit electronic documentation to attending Class Surveyor.
