1. A method of making a low sulfur marine bunker fuel oil composition, the method comprising:
producing a vacuum tower bottoms having a sulfur content of less than about 2 percent by weight;
filtering a decant oil to at least partially remove fluid catalytic cracking catalyst fines to reduce an aluminum and a silicon content and produce a filtered decant oil therefrom;
blending the filtered decant oil into the vacuum tower bottoms, the filtered decant oil having a sulfur content of less than about 1 percent by weight; and
blending a vacuum gas oil having a sulfur content of less than about 0.1 percent by weight into the vacuum tower bottoms that is blended with the filtered decant oil to define the low sulfur marine bunker fuel oil composition, the low sulfur marine bunker fuel oil composition having about 12 percent to about 50 percent by volume of the vacuum tower bottoms, at least about 16 percent by volume of filtered decant oil and about 25 percent to about 74 percent by volume of vacuum gas oil, the low sulfur marine fuel oil composition also having a combined volume of the vacuum tower bottoms and the filtered decant oil that is at least about 50 percent, a final sulfur content of less than about 0.5 percent by weight, and an aromatic content of greater than about 50 percent by weight.
