Heading Reference
· Gyroscopic Heading Reference
Voltage: 24V DC / 115V AC
type: Gyrocompass (Mechanical / Fibre-Optic)
size_range: ['Standard 22', 'Standard 22 NX', 'Horizon MF']
variant_count_approx: 3
period_start_year: 1990
period_end_year: None
drive_type: Electric
construction: Spinning mass gyro (Standard 22) / Fibre-Optic (Horizon)
Common Failures:
- • Spinning mass gyro bearing wear after 40,000+ hrs (mechanical)
- • Follow-up system motor failure
- • Heading settling time excessive after power interruption
- • Fibre-optic coil degradation from vibration (FOG models)
- • Compass card repeat signal failure
Service: Spinning mass gyro: bearing replacement every 40,000-60,000 hrs. Follow-up system check quarterly. Heading error check vs. celestial/GPS monthly. Annual survey.
Spares: Wärtsilä Voyage (Kiel). Gyro rotor assembly: 6-10 weeks. Follow-up motor: 3-5 weeks.
