Marine electronic failures often begin as intermittent alarms, dim displays, unstable power, connector corrosion, antenna damage, or lost configuration. A planned inspection routine helps crews find degradation early.
Inspect operator equipment
Check display brightness, touch response, keys, alarm sounders, mounting, ventilation, and day/night dimming. Confirm that time, position, heading, speed, and shared sensor data are plausible across connected equipment.
Check power and grounding
- Power supplies, breakers, fuses, UPS units, and batteries
- Loose, corroded, or overheated terminals
- Protective earth, bonding, and cable shields
- Backup power alarms and battery condition
Inspect antennas, sensors, and cables
Examine accessible radomes, antennas, cable glands, connectors, junction boxes, and cable routes for damage, ultraviolet ageing, water entry, and corrosion. Clean sensor faces only as the manufacturer recommends.
Review networks and records
Check link status, communication errors, alarms, redundancy, and event logs. Maintain controlled backups of configurations, databases, charts, licenses, network settings, and calibration data.
Prepare replacement details
Provide the equipment function, manufacturer, exact part number, revision, photographs, interfaces, supply, quantity, and vessel delivery location to US² Automation.
