🔍 River Navigation Electronics Faults at Kolkata Port
| Reported Defect | Root Cause Diagnosis | Technical Remediation |
|---|---|---|
| Echo Sounder Transducer Signal Loss in River Silt | Heavy river mud accumulation and acoustic impedance mismatch on 50/200 kHz dual transducer. | Transceiver gain recalibration, transducer cleaning, and draught offset verification. |
| River Radar High Close-Range Clutter | Misaligned STC curve and deteriorating magnetron in high-clutter river bends. | Magnetron replacement, AFC optimization, and receiver video gain tuning. |
Echo Sounder & River Radar Overhaul at Netaji Subhash Dock
Reported Problem: Vessel failed river pilot inspection due to echo sounder missing bottom lock and radar losing river buoy markers.
Technical Diagnosis: Echo sounder receiver amplifier drifted out of resonance; radar magnetron emission depleted to 40%.
Corrective Attendance: Boarded at NSD Berth 3. Replaced radar magnetron, tuned AFC circuit, recalibrated echo sounder analog preamp, and verified river depth readings against lead line.
