VDR / S-VDR Annual Performance Test (APT) & Certification India
Preparing for a VDR or S-VDR annual performance test
Send the VDR make and model, previous annual performance test certificate, and next due date. List any recent changes to bridge audio, radar, ECDIS, AIS or other recorded inputs so the attending team can review the test scope.
Seanav Marine coordinates VDR and S-VDR annual performance tests through its accredited channel partners. Send the recorder make, model, vessel details and due date so the technical desk can confirm the attending provider, testing scope and reporting arrangements for your vessel. Acoustic beacon replacement and fault rectification can be scoped separately.

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.
