Before a vessel leaves port, a thorough check of the steering gear is critical to ensure safe navigation and maneuverability. Here’s a comprehensive list of necessary checks:

Functional Checks:

• Main Steering Gear:
  • Test full rudder movement from hard-over to hard-over in both directions.
  • Verify smooth and responsive operation without excessive noise or vibration.
  • Check for any leaks or unusual sounds from the hydraulic system.
• Auxiliary Steering Gear (if fitted):
  • Test its operation and rudder movement in both directions.
  • Ensure it can be switched over seamlessly in case of main steering gear failure.
• Remote Control Systems:
  • Test all remote steering control stations on the bridge and other locations.
  • Verify communication between the bridge and steering gear compartment.
• Emergency Power Supply:
  • Test the emergency power supply to the steering gear, ensuring it can provide adequate power in case of a main power failure.
• Rudder Angle Indicators:
  • Check that rudder angle indicators on the bridge and in the steering gear compartment are accurate and functioning correctly.
• Alarms and Safety Systems:
  • Test all steering gear alarms, including power failure alarms, low oil level alarms, and overload alarms.
  • Verify the operation of any automatic isolating equipment or safety features.

Visual Inspections:

• Steering Gear Components:
  • Visually inspect all components of the steering gear, including rams, tiller, linkages, hydraulic lines, valves, pumps, and motors, for signs of wear, damage, or leaks.
  • Check fluid levels in the hydraulic reservoir and ensure the fluid is clean and free of contamination.
• Rudder and Associated Equipment:
  • Inspect the rudder for any damage or signs of excessive wear.
  • Check the rudder carrier bearing and pintles for proper lubrication and smooth movement.
  • Inspect the rudder stock packing for leaks.

Documentation and Records:

• Maintenance Logs: Review the steering gear maintenance logs to ensure all required maintenance and repairs have been carried out and are up to date.
• Test Procedures: Follow the vessel’s specific steering gear test procedures and document the results of all checks and tests.

Additional Considerations:

• Steering Gear Room: Ensure the steering gear room is clean, well-lit, and free of obstructions.
• Communication: Test communication systems between the bridge and steering gear compartment to ensure clear and effective communication during operation.
• Crew Familiarity: Ensure that all crew members involved in steering operations are familiar with the steering gear system, its controls, and emergency procedures.
• Testing Frequency: Steering gear tests should be carried out at regular intervals as per regulations and the vessel’s safety management system.
• Pre-Departure Checks: Perform final steering gear checks before leaving port, especially after any maintenance or repairs have been carried out.

By diligently conducting these necessary checks before departure, you can enhance the safety and reliability of the steering gear system, ensuring that the vessel is maneuverable and can respond effectively to any steering commands during its voyage.
