BUNKER ALERT - HIGH CAT FINES FUELS IN SINGAPORE

We have received the following from DNV Petroleum Services.  Several heavy fuel oil samples from bunkerings in Singapore with combined Aluminium and Silicon levels exceeding the limit set in ISO 8217:1996 of 80 mg/kg. The highest Al+Si content was 180 mg/kg, with an average level of 130 mg/kg. Vessels receiving such fuels may experience abrasive wear of fuel handling equipment and engine components. If your vessel recently bunkered in Singapore, please ensure that the fuel quality is known before using it. At these high levels of cat fines, the fuel must be efficiently centrifuged in order to adequately remove these abrasive contaminants. For optimum centrifuge performance operate the centrifuges in series and reduce the fuel throughput as much as possible. However, we cannot guarantee such operation will remove the abrasive materials. To determine the efficiency of the centrifuges we recommend analysis of samples taken before and after the centrifuge. This may be important to help you avoid serious damage to shipboard machinery.
