BOTTOM LINE UP FRONT (BLUF)
Seanav Marine delivers 24/7 emergency attendance, annual calibration, and sea trial tuning for commercial marine autopilot and heading control systems across Port of Sohar, Port of Salalah, Port of Duqm, Duqm Anchorage, and Port Sultan Qaboos (Muscat). We service Sperry Marine (Navipilot 4000/4500), Tokyo Keiki (PR-6000/PR-9000), Raytheon Anschütz (NautoPilot 5000), Simrad (AP70/AP80), Furuno (NAVpilot), and ComNav systems, resolving rudder hunting, solenoid interface dropouts, gyro heading sync alarms, and feedback transmitter failures with rapid port mobilization.
Autopilot & Steering Control Engineering Across Oman
Navigating through dense commercial waterways—including the Gulf of Oman, Arabian Sea, and Indian Ocean deep-water corridors—demands flawless autopilot course stability. Any steering anomaly, such as rudder hunting (±5°), off-heading drift, or failure to lock onto gyrocompass heading, poses immediate collision hazards and PSC detention risks.
Seanav Marine deploys experienced marine navigation engineers equipped with factory diagnostic tools, optical angle calibrators, and solenoid interface testers to service autopilots onboard container vessels, tankers, bulk carriers, and offshore support vessels calling at Port of Sohar, Port of Salalah, Port of Duqm, Duqm Anchorage, and Port Sultan Qaboos (Muscat).
Rudder Feedback Calibration
Precision zero-point calibration, deadband alignment, and potentiometer/resolver replacement for Rudder Feedback Units (RFU) to eliminate rudder oscillation and hunting.
Heading Input Synchronization
Interfacing gyrocompass ($HEHDT) and magnetic compass ($HCHDG) inputs via NMEA 0183, step-by-step, or synchro, ensuring instantaneous failover during primary compass loss.
Steering Gear Solenoid Interface
Diagnostics of proportional amplifier valves, port/starboard directional solenoids, hydraulic power pack relays, and non-follow-up (NFU) override circuits.
Adaptive Sea State Tuning
Custom parameter configuration for rudder gain, counter rudder, yaw damping, and weather trim to prevent steering gear wear and hydraulic overheating.
Emergency Autopilot Deadband & RFU Overhaul at Port of Sohar Liquid Cargo Berth 2
Fault: Severe rudder hunting (±4°) during harbor approach, causing hydraulic relief valve chattering and high-temperature alarms.
Action: Replaced noisy potentiometer in steering gear feedback unit, set digital zero center-point, and re-tuned deadband parameters.
Result: Sea trial verified stable heading hold within ±0.3°; vessel sailed without commercial delay.
