## Abstract

This invention relates to low sulfur marine bunker fuel compositions and methods of making the same. The invention also relates to an uncracked, hydrotreated vacuum resid for use in making the low sulfur marine bunker fuel composition. Contrary to conventional marine/bunker fuel compositions, the low sulfur marine/bunker fuel composition uses mostly uncracked components, including a (cat feed) hydrotreated vacuum resid. The low sulfur marine/bunker fuel composition can also have reduced contents of residual components.
