What STEPS / PROCEDURE to follow by ship's staff when fuel oil analysis does not meet the quality requirements?
Long story short:there are to usual approaches of dealing with off-spec fuel (besides de-bunkering):
- Purification - run 2 purifiers (if available) in sequence at minimum possible flow rate and reduced de-sludging period down to 1-hour or less, depends on severity of contamination. Keep close monitoring of recommended purification temperature.
- Fuel additives. We used Octomar BT-25 and it had showed excellent results. We inspected bunker tanks after applying Octomar and found them in good clean condition. Sludge amount was reduced, combustion improved.
