By Engr Matahula, Smart Pwashemeno

Overhauling fuel oil purifiers on merchant ships typically involves a series of maintenance procedures to ensure their optimal performance. Here is a general guideline for overhauling fuel oil purifiers:

1. Preparation:
   • Obtain the necessary tools and spare parts for the overhaul.
   • Review the manufacturer’s instructions and guidelines for the specific purifier model on your ship.
   • Ensure that you have appropriate personal protective equipment (PPE) for the task.
2. Shutdown and Isolation:
   • Shut down the purifier and isolate it from the fuel system by closing the relevant valves.
   • Drain any remaining fuel and ensure the system is depressurized.
3. Disassembly:
   • Carefully disassemble the purifier according to the manufacturer’s instructions.
   • Remove the bowl assembly, discs, and all other removable parts.
   • Inspect the parts for signs of wear, damage, or blockages.
4. Cleaning:
   • Thoroughly clean all disassembled parts, including the bowl, discs, and other components.
   • Use appropriate cleaning agents recommended by the manufacturer.
   • Ensure that no debris or sludge remains on the parts.
5. Inspection:
   • Inspect all parts for wear, corrosion, or other damage.
   • Pay particular attention to the discs, as they may require replacement if worn beyond acceptable limits.
   • Check gaskets and seals for signs of wear and replace them as needed.
6. Reassembly:
   • Follow the manufacturer’s instructions to reassemble the purifier, ensuring proper alignment of all components.
   • Lubricate moving parts as recommended by the manufacturer.
   • Replace any worn or damaged parts with new ones.
   • Ensure all gaskets and seals are properly installed.
7. Testing and Calibration:
   • Once the purifier is reassembled, perform tests to verify its functionality.
   • Adjust and calibrate the purifier as per the manufacturer’s guidelines.
   • Check for any leaks, abnormal vibrations, or irregularities during the testing process.
8. Documentation:
   • Maintain a record of the overhaul, including the date, details of parts replaced, and any issues encountered.
   • Update the maintenance logbook and relevant documentation.

Please note that this is a general guideline, and specific procedures may vary depending on the purifier model and manufacturer. It is essential to refer to the manufacturer’s instructions and seek guidance from qualified personnel with experience in maintaining fuel oil purifiers.
