1. A method of making a low sulfur marine bunker fuel oil composition, the method comprising:
producing residuum in a distillation column;
producing asphaltene stabilizer in a fluid catalytic cracker (FCC) configured to receive a hydrotreated hydrocarbon feed;
blending the residuum with the asphaltene stabilizer to form an intermediate blend; and
blending the intermediate blend with a low sulfur cutter stock to define the low sulfur marine bunker fuel oil composition, the low sulfur marine bunker fuel oil composition having a final sulfur content of less than 0.5 wt. %.
