| Radar Blind Sector / Low Sensitivity at Anchorage | Magnetron emission deterioration or corrupted waveguide circulator after heavy monsoon sea passage. | Magnetron replacement and AFC cavity re-tuning at Indira Dock berth. |
| Gyro Compass 4-Degree Constant Error | Contaminated supporting liquid or rotor imbalance in Tokyo Keiki / Yokogawa gyro. | Flushing, fresh fluid replenishment, and meridian settling test before departure. |
Emergency Gyro Compass Overhaul at Butcher Island (Jawahar Dweep)
Reported Problem: Master reported gyro heading hunting continuously by ±7° while discharging cargo at JD-3 berth, triggering steering failure alarm.
Technical Diagnosis: Sensitive element sphere support fluid severely oxidized; lower rotor bearing showed excessive mechanical friction.
Corrective Attendance: Dispatched technician from Navi Mumbai depot with replacement gyrosphere (M-22DM) and fluid. Dismantled binnacle, cleaned chamber, renewed fluid and mercury contacts, and completed meridian settling.
