Autopilot Sea Trial Testing Checklist

Autopilot Sea Trial Testing Checklist

Pre-Trial Preparations

1. Documentation and Manuals:

• Gather and review all relevant documentation and manuals for the autopilot system.

1. System Inspection:

• Verify all components of the autopilot system are properly installed.
• Check the connections of sensors (gyrocompass, GPS, rudder angle indicator, etc.).
• Ensure power supply to the autopilot is stable and correctly fused.

1. Software and Firmware:

• Confirm that the latest software/firmware updates are installed on the autopilot system.
• Verify the autopilot software is configured correctly for the vessel.

1. Safety Checks:

• Ensure all emergency stop procedures are known and functional.
• Confirm manual steering is operational and can override the autopilot at any time.

During Sea Trial

1. Initial System Test:

• Power on the autopilot system and check for any error messages.
• Confirm the autopilot interface is responsive and all displays are readable.

1. Sensor Verification:

• Check the accuracy of the compass/gyrocompass.
• Validate GPS functionality and accuracy.
• Test the rudder angle indicator for correct readings.

1. Basic Functional Tests:

• Engage the autopilot in calm waters.
• Set a straight course and observe the autopilot’s ability to maintain it.
• Check the system’s response to minor course adjustments.

1. Turning and Maneuvering:

• Execute a series of controlled turns to both port and starboard.
• Assess the autopilot’s ability to follow a preset turn radius.
• Monitor the system’s response time and accuracy in returning to a set course.

1. Speed Variation:

• Test autopilot performance at various speeds.
• Check for any deviations or lag in maintaining course during speed changes.

1. Environmental Condition Testing:

• Evaluate autopilot performance in varying sea conditions, including waves and currents.
• Observe the system’s stability and accuracy in maintaining the course under different conditions.

1. Advanced Functional Tests:

• Engage and test the automatic route-following capability if available.
• Validate waypoint navigation by setting multiple waypoints and observing transitions.
• Test advanced features such as wind steering or following a specific wind angle (if applicable).

1. Emergency Situations:

• Simulate a loss of GPS signal and observe autopilot behavior.
• Test manual override to ensure quick and reliable switching to manual control.
• Check the response of the autopilot to a sudden engine stop or propulsion failure.

Post-Trial

1. Data Analysis:

• Review the logged data from the sea trial for any anomalies or deviations.
• Analyze performance metrics such as course accuracy, response times, and stability.

1. System Adjustment:

• Make any necessary adjustments to the autopilot settings based on trial results.
• Update the system software/firmware if required.

1. Final Inspection:

• Conduct a final inspection of all autopilot components for wear or damage.
• Ensure all connections are secure and components are functioning correctly.

1. Reporting:

• Compile a detailed report of the sea trial, including all observations, issues encountered, and actions taken.
• Provide recommendations for any further actions or adjustments needed.

1. Crew Training:

• Ensure that the crew is adequately trained on the operation and troubleshooting of the autopilot system.
• Provide documentation and conduct a review session based on the sea trial results.

Notes:

• Always conduct sea trials under the supervision of experienced personnel.
• Ensure all safety protocols are in place and followed throughout the testing.
• Maintain communication with the bridge team during all phases of the trial.
