⚓ Why is Annual Gyro Compass Overhaul Important?

The gyro compass is a critical navigation tool onboard—integrated with autopilot, radar, ECDIS, and AIS. Over time, even the most robust gyro systems can drift or degrade in accuracy. A scheduled annual overhaul ensures:

✅ Precision heading for safe navigation
✅ Compliance with IMO & Class regulations
✅ Early detection of component wear or failure
✅ Reduced downtime during critical voyages

🔍 Full disassembly & inspection of internal components
