On board ships, dozens of motors are used for various purposes in both the deck and engine departments. Each motor is equipped with a dedicated starter panel, which is responsible for the switching operations, such as turning the motor on and off. Just like any other machinery system, these motor starter panels require regular maintenance to ensure the smooth operation of the motors.

Importance of Starter Panel Maintenance

Maintaining the starter panels is crucial for the overall performance and safety of the motors on board ships. Regular maintenance helps in identifying and rectifying any potential issues before they escalate into major problems. It also ensures that the motors are functioning optimally, reducing the risk of breakdowns and costly repairs.

Components of a Starter Panel

A typical starter panel consists of several components that work together to control the motor’s operation. These components include:

  • Circuit Breakers: These protect the motor from overloads and short circuits by interrupting the flow of electricity when necessary.
  • Relays: Relays are responsible for controlling the switching of the motor, allowing it to start and stop as required.
  • Control Switches: These switches enable manual control of the motor, allowing the operator to start or stop it when needed.
  • Indicator Lights: Indicator lights provide visual feedback on the status of the motor, indicating whether it is running or experiencing any faults.
  • Fuses: Fuses protect the starter panel and motor from excessive current by melting and breaking the circuit in case of a fault.

Regular Maintenance Tasks

To ensure the proper functioning of the motor starter panels, the following maintenance tasks should be carried out regularly:

1. Visual Inspection

Perform a visual inspection of the starter panel to check for any signs of damage, loose connections, or overheating. Look for burnt or discolored components, loose wires, and any other visible abnormalities.

2. Cleaning

Clean the starter panel to remove dust, dirt, and debris that may accumulate over time. Use a soft brush or compressed air to clean the components, ensuring that no foreign particles interfere with their operation.

3. Tightening Connections

Check and tighten all electrical connections within the starter panel. Loose connections can lead to overheating and electrical faults, affecting the motor’s performance. Ensure that all terminals, screws, and wires are securely fastened.

4. Testing

Regularly test the functionality of the starter panel by simulating various operating conditions. Verify that the relays, circuit breakers, and control switches are working correctly. Also, check the indicator lights to ensure they are functioning as intended.

5. Calibration

If necessary, calibrate the starter panel to ensure accurate operation and control of the motor. Follow the manufacturer’s guidelines or consult a qualified technician for proper calibration procedures.

6. Documentation

Maintain a record of all maintenance activities carried out on the starter panels. This documentation helps in tracking the maintenance history and identifying any recurring issues that require attention.


Regular maintenance of the starter panels is essential for the reliable and efficient operation of motors on board ships. By performing visual inspections, cleaning, tightening connections, lubrication, testing, calibration, and proper documentation, ship operators can ensure the longevity and optimal performance of their motor starter panels. Neglecting this maintenance can lead to motor failures, costly repairs, and potential safety hazards. Therefore, it is crucial to prioritize the maintenance of starter panels to keep the ship’s motors running smoothly.
