• Area: Pressure gauge calibration verification
  Check: Verify boiler pressure gauges are calibrated. Shut-off fittings must be clearly marked in open position. If calibration cannot be verified, obtain written statement from Master/Chief Engineer or use secondary gauge for verification. Critical for SOLAS compliance on all auxiliary and main boilers.
• Area: Safety valve function and adjustment
  Check: Ensure minimum 2 safety valves per boiler, adjusted under steam to not exceed 103% of approved design pressure. Test operational response and relieving capacity. Document valve settings in ship's records.
• Area: Furnace refractory and soot deposits
  Check: Inspect furnace refractory twice yearly minimum for cracks, brick displacement, and excessive soot accumulation. Check for hot spots or areas of excessive heat damage. For oil-fired boilers, soot removal via water jet cleaning (0.4-0.6 MPa, ~50 litres/min) between inspections.
• Area: Water tube condition and scale/corrosion monitoring
  Check: Inspect water side of tubes for scale, corrosion, and deposits. Check for pin-hole leaks or bulging. Verify tube plate integrity and gasket condition. For oil-fired auxiliary boilers, water jet clean tubes when out of service. Replace corroded or damaged tubes per manufacturer specifications.
• Area: Soot blower and burner maintenance
  Check: For boilers equipped with soot blowers: check for distortion, worn bearings, nozzle cracks, freedom of movement, and effective lubrication. Verify nozzles are not blocked. For burners: clean/replace atomiser tip, verify fuel pressure/temperature, test ignition system, inspect fuel pump condition, review burner management system fault history.
