As cat fines-laden 1.0% low sulfur fuel oil, which was used mainly by ECA bound ships, has been reintegrated into high sulfur bunker market from January 2015, the risk to all ship operators has likely increased. Furthermore, the compulsory reintroduction of low sulfur fuel oil for use in the EU waters (and also possibly in international waters on January 2020) will amplify the problem caused by the inclusion of cat fines in fuel as suppliers blend additional heavy cycle oil, which is the source of cat fines, to achieve a 0.5% fuel sulfur maximum. Conventional 5 micron fuel filters, such as barrier-type filters, can block asphaltenes in fuel. As a result, operators normally select filter pore sizes that are equal or greater than 10 microns. On the other hand, five micron depth-type filters have the ability to capture and remove cat fine particles from fuel without blocking fuel. Bench testing of 5 micron depth-type filtration technology resulted in an average removal efficiency of 92.9% across all particle diameter sizes that range from 3 to 5 microns, 5 to 10 microns, 10 to 15 microns, 15 to 25 microns, and 25 to 50 microns. The new DREWCAT Fine Filter from Drew Marine has the ability to fully mitigate the risk from cat fines contamination and protect ship engines from premature engine machinery wear.
