The quality of bunker fuel continues to be a source of concern to shipowners and charterers. Over the last 30 years or so, enhanced refining techniques have resulted in a decline in the quality of residual fuel and the refinery side streams used as blend components. Added to this the demand for low sulphur fuel has resulted in heavy blending and the use of inappropriate blend components. Unfortunately some marine fuels have also been used as a dumping ground for waste chemicals and organic substances that have caused serious operating problems. Engine damage and resultant lost time caused by bunker quality problems occur all too frequently.
